will increase the treatment capacity to 130,410 gpd. Table 1 shows the details of the flow-rates during each phase of the design. As shown, a fine screen will require a spray water flow-rate of 10,000 gpd to clean the screen and carry the screenings to the adjacent sewer. Since the treated water will be used as the spray/conveyance water, the treatment process units will be designed to treat this additional volume. Since MBR systems use membrane filtered water for backwashing and chemical cleaning of the membranes, approximately 15% of the treated water will be consumed for this function. In addition, waste activated sludge (WAS) volumes needs to be accounted for when calculating the gross production capacity of the process units. The gross treatment capacity of the treatment train was calculated by taking into account recycled water end user demand, fine-screen spray/conveyance water, backwash/cleaning water for membranes and WAS volume.

INFLUENT WASTEWATER CHARACTERIZATION In order to characterize influent wastewater, several grab and composite samples were collected over a period of two weeks. Since the MBR system will be designed as a scalping plant, flow-rate to the plant will generally remain constant throughout the day. The primary purpose of the sampling was to determine the variations in the contaminant loading rate to the plant. 24-hr time composite samples were collected to determine average, maximum month, maximum week and maximum day organic loading rates. Table-2 shows the water quality sampling plan that was implemented for influent wastewater characterization. The wastewater samples were collected from trunk sewer near Oak and Lemon Street. The project team awaiting final lab results for the last few samples.

PROCESS DESCRIPTION The proposed treatment process flow diagram shown in Figure-2 consists of MBR, ozone and UV treatment processes. The detailed layout of individual unit processes and a full copy of the process flow diagram, equipment list and preliminary chemical volume calculations are shown in Appendix B. Wastewater from the trunk sewer will be pumped to the WRF using chopper/grinder pumps in order to avoid any clogging in the transfer line. Wastewater will be treated using a fine screen at the WRF and distributed by gravity to the pre-anoxic zone of the MBR process. The MBR process will be designed as a 4-stage Bardenpho process with pre-anoxic and post-anoxic zones to achieve low effluent Total Nitrogen (TN) concentration. The facility will be designed with provisions for carbon addition in the post-anoxic zone in order to achieve low effluent nitrate concentration. As specified in the draft design report prepared by PBS&J, an external tubular configuration membrane system (commercial name DynaLift) will be used for filtration. This configuration offers several benefits specific to this facility. The DynaLift membrane system is located outside of the biological process tanks, which simplifies chemical cleaning as the membranes do not have to be removed from the biological process tanks. In addition, since the membrane modules can be drained and filled with cleaning chemicals, the chemical cleaning process does not require lifting the membrane modules out of the tank. Membrane filtered effluent will be collected in a 500-gallon equalization tank that will serve as a feed tank to the ozonation system. The purpose of providing the equalization tank is to allow the use of booster pump to feed the ozonation system and to allow for continuous flow to the ozonation system while the membranes are being backwashed. Since the membrane effluent will have a pressure of less than 2 psi, a booster pump will feed the membrane treated water to the ozonation system, where the water will be treated further to remove residual color, odor and to provide disinfection. The selected ozonation system is Title 22 approved system. It will be designed to deliver sufficient dose and contact time to achieve effluent water quality standards that comply with Title 22 water quality standards for tertiary disinfected water. Ozonated effluent will then be passed through the UV unit, which will serve as a secondary barrier against microbial contaminants. Each of the unit treatment processes will be described in detail in the following sections. Each unit process will be equipped with instrumentation and control devices (factory supplied panels) provided by the vendors and communication from each unit process will be set up with the SCADA system.

FINE SCREENING Membrane clogging due to hair and fibrous materials can result in loss of membrane area and productivity of the membrane filtration system. In order to avoid this problem, raw wastewater is always filtered by a fine screen before being fed to the bioreactors and the membrane modules. The project team will use a center feed perforated rotating drum screen with openings of 1 mm.

Design Specifications and Power Requirements The proposed drum screen is manufactured by Waste Tech, based in Spartanburg, SC and the specifications of screen are presented in Table 5. The detailed specifications for the fine screen equipment are shown in Appendix C.

The Waste Tech rotating drum screen incorporates a feed distribution head box for effective flow distribution and an internally screw auger with individual dewatering cells which dewaters and transports the separated solids out of the drum. Depending on the size of the screen the drum is direct drive, cog fear drive or trunnion driven. The influent to the drum is distributed over a large area of the drum to ensure efficient use of the drum open area. As the drum rotates, fluid passes through the perforations and the solids are removed and dewatered from the drum by the fixed transport screw. Since the enclosed perforated drum screen has no seals or slots, all flow must pass through the perforations, which prevents bypass or carryover of solids to the downstream process. An automatic Integral Overflow System (IOS) within the screen equipment provides an alarm indication when screen is clogged in order to prevent raw wastewater from contaminating the filtered effluent. Separate overflow connection allows raw wastewater to be diverted to the sewer in the event of screen being clogged. Treated water from the clearwell will be used periodically (usually every 15-20 minutes for 10-15 seconds) as spray water for the spray system to wash away biological slimes, grease, etc. A mechanical brush continuously cleans the outside of the screen whereas the spray water is used as a secondary mechanism to clean the drum. The system shall be equipped with controls to provide both manual and automatic operation. Controls shall be housed in a NEMA 4X enclosure complete with HOA Switch for screen drive, ON/OFF Lights, Fail Lights, Overflow Alarm Light, Main Disconnect with panel mounted disconnect lockable in the off position. All necessary starters, breakers, fuses, timers and relays for Automatic and Manual Control.

Scope of Supply & Equipment Warranty The supplier shall furnish one RDS-OF-30 perforated drum screen with NEMA 4X controls, spares, anchor bolts, site service and provide delivery to site. The supplier shall also furnish, boxed for storage and clearly marked, the following spare parts: two complete trunnion wheel assemblies. The screen equipment is warranted for 2 years after installation.

MEMBRANE BIOREACTOR Membrane Bioreactor (MBR) process is an advanced wastewater treatment process which uses membranes for solids separation instead of clarifiers. Use of membrane for solids separation allows the process to operate at high MLSS concentration (8,000-12,000 mg/L) irrespective of sludge settling characteristics and provides superior effluent water quality. Operation at high MLSS also reduces the required bioreactor volume and use of membrane replaces the need for clarifiers and media filters thereby reducing the overall footprint of the plant. Typically, a well operated MBR process with intact membranes will produce effluent with BOD and TSS below detection levels and turbidity of <0.2 NTU. Since MBRs are usually designed to operate at higher sludge retention times (SRT), effluent is fully nitrified and effluent ammonia concentrations are maintained at < 0.5 mg/L-N. MBR process can be categorized as either submerged or external depending on if the vacuum or pressure is used to produce permeate. Submerged MBR systems are more frequently used in municipal wastewater application since external MBR systems are perceived to be more energy intensive. The external MBR process requires a higher recirculation flow-rate for cross-flow pumping to provide enough hydrodynamic shear for membrane scouring. But high flux operation and recent advances in external MBR systems such as air-lift assisted cross-flow pumping have made external MBR systems competitive to submerged MBR systems. External MBR systems also offer an advantage in ease of cleaning since it is not required to lift the module out of the membrane tank for chemical cleaning.

BIOLOGICAL PROCESS CONFIGURATION MBR systems are usually designed using the MLE process with dual recycle configuration. Since the recycle stream from the membrane tank has high dissolved oxygen (DO) concentration (3-5 mg/L), it is usually diverted to aeration tank instead of to the anoxic tank. Denitrification is then achieved by having an internal recycle from aeration to anoxic tank. Recycle flow from aeration to membrane tank is dictated by the desired MLSS concentration in the membrane tank, which is usually 10,000-12,000 mg/L. Alternatively, when designed with single recycle configuration, a larger anoxic tank volume is required to quench the DO from the membrane to anoxic recycle stream. The project team proposes to install a MBR process with single recycle configuration with allowance to split the membrane recycle flow to aerobic and pre-anoxic zones. Screened influent will pass to the pre-anoxic tank to utilize influent BOD for denitrification process. Mixed liquor will flow by gravity from the pre-anoxic tank to the aeration tank for nitrification. Nitrified effluent from the aeration tank will then flow by gravity to the post-anoxic tank for additional denitrification. The process will be designed with provision for addition of MicroCg (agriculturally derived carbon source) to the post-anoxic zone to achieve low effluent nitrate concentration (< 5 mg/L NO3-N).

Denitrified wastewater from the post-anoxic tank will be pumped to the membrane tank for filtration. The recycle flow-rate from the post-anoxic tank to the external membrane system will

TM-001 Preliminary Process Design August 7, 2009

TM 001_Process_v1.docxocess_V1.docx 11 of 36

vary from 12-15 times the influent flow-rate. Since the recycle stream from the membrane tank has high DO concentration (3-5 mg/L), provisions will be made to split the membrane recycle flow such that the recycle flow can be diverted to either pre-anoxic tank or aerobic tank or both. Such provision will allow maintaining anoxic conditions in the pre-anoxic tank by diverting part of the membrane recycle flow to aerobic tank if DO concentration in the recycle stream is high. The biological process is designed with an SRT of 20 days and detailed calculations for pumps, blowers and mixers sizing are shown in Appendix D. A BioWin model was prepared to predict effluent water quality and bioreactor conditions at steady state as well as to simulate different contaminant loading conditions. Results from BioWin modeling are also shown in Appendix D. The results shown from BioWin modeling are currently based on maximum week concentrations only determined from the 24-hour composite samples. Designing to the maximum week loading will ensure meeting the maximum month requirement for effluent nitrate. The project will further simulate diurnal fluctuations in organic loading rate when the results for the diurnal sampling are received. Model runs for annual average, maximum month and maximum day loadings will also be verified at that time. Based on the steady state analysis, the proposed biological process design will achieve effluent nitrate concentration of < 5 mg/L-N on a monthly average basis.

MEMBRANE FILTRATION In accordance to the draft engineering report prepared by PBS&J (June 8, 2009), the membrane system to be specified is the DynaLift membrane system provided by Parkson Corporation (Fort Lauderdale, FL). As part of the preliminary process design, the project team requested Parkson Corporation provide the following information associated with the DynaLift system:

• Scope of supply • equipment specifications, • membrane design criteria, • warranty information, • list of reference plants.

As part of this request, the project team provided Parkson influent water quality and effluent water goals, along with the preliminary biological process design parameters. During a follow up conversation with Parkson’s MBR Group Manger, the project team was asked to contact Norit X-Flow (Enshede, Netherlands) to obtain the requested information regarding the DynaLift membrane system. Norit X-Flow is the membrane manufacturer and developer of the technology (commercial name AirLift MBR) used in the DynaLift membrane system. After further discussions with Norit, it was explained to the project team that Parkson is no longer an authorized supplier of the DynaLift technology. Based on further discussions with Norit X-Flow, the project team was informed that Dynatec Systems, Inc. (Burlington, NJ) was the original and current authorized representative of the DynaLift technology in the United States. Dynatec has been providing membrane systems for wastewater treatment applications for 30 years with many small capacity (<200,000 gpd) industrial and municipal DynaLift MBR systems currently operating in the United States. Based on discussions with Dynatec, the DynaLift system design they provide is similar to Parkson’s design with the major difference being the feed and product header configuration. After speaking with the Dynatec representative and qualifying their experience and knowledge of the municipal DyanLift MBR technology, the project team has selected this firm to provide the membrane equipment for the City of Anaheim MBR facility. Table 8 summarizes Norit’s MBR plants currently operating in the United States and overseas.

Scope of Supply & Equipment Warranty An example of a typical pro-rated lifetime membrane warranty provided by Norit is provided in Appendix E. In general, the terms of the warranty replace a membrane element found to be defective in the first 12 months at no cost to the owner. However, membranes identified to be defective after 12 months are replaced at a prorated charge calculated as follows: Pro-rated membrane replacement = New Membrane Cost x Months of Beneficial Use Total Membrane element warranty period (36 months) The warranty is also subject to a number of conditions related to the operation and performance documentation. In addition to membrane warranty, Dynatec will provide manufacturer warranty on all equipment associated with the membrane system (i.e. blowers, pumps, valves, chemical dosing systems, gauges, etc.). A complete scope of supply, equipment list, and budgetary cost estimate for the DynaLift membrane system is currently being prepared by Dynatec and will be incorporated into the overall engineering estimate of the plant in the final TM.

OZONATION Ozonation is an alternative disinfection technology for reuse applications. Like chlorine, ozonation is also considered a chemical disinfection process. However, ozone is a much stronger disinfectant than chlorine, and does not produce DBPs such as trihalomethanes (THMs) and haloacetic acids (HAAs). Other DBPs may be formed from ozonation (bromate), but this process depends on the bromide concentration in the water (expected to be low in this case) may be successfully controlled by pH adjustment and peroxide addition. For long time, UV has dominated the disinfection market due to the very short contact times required to achieve the desired inactivation goals. Ozone, on the other hand, is a gas sparingly soluble in water, which requires longer contact time to dissolve and become effective for disinfection. For this reason, the traditional ozonation process requires large contact basins with multiple contact chambers. Ozone is bubbled in the first 2-3 chambers and additional contact/reaction time is provided by the subsequent chambers. The contact time (CT) requirements for disinfection are met when the effluent leaves the last chamber. However, for applications of the size required at the WRF, alternative ozonation systems are available. Pressurized plug-flow tubular reactors, where ozone can be added in sequential steps, allow ozone to dissolve faster in water, and to utilize it more efficiently than using contact basins (i.e., by increasing dissolution in water, ozone losses to air are reduced). Under these conditions, ozone can compete effectively with UV to achieve the required disinfection goals for recycled water. Other advantages of ozonation over the UV process include providing higher dissolved oxygen (DO) to the effluent, as well as leaving a measurable residual to confirm the required disinfection goals, both advantageous conditions for recycled water applications. Successful implementation of this technology for Title 22 applications has been reported by Applied Process Technologies (APT) and their product known as the HiPOx® reactor. Data from prior applications indicate that when the objective is achieving disinfection equivalent to the irradiation of a 100 mJ/cm2 UV dose, the HiPOx reactor can achieve this same objective in a more cost effective manner. To accommodate the plant extension during the second phase of this project, the capacity of the proposed reactor can be easily doubled to 100,000 gpd (nominal) by using a pipeline array extension and an extra ozone generator. An extra generator may be also added later for redundancy. The selected ozone reactor has two more important advantages over UV:

• Substantial improvement to effluent water quality, especially with respect to odor and

color. • Removal of trace contaminants, such as endocrine disruptors (EDCs), and pharmaceutical

and personal care products (PPCPs), especially when used in conjunction with hydrogen peroxide for advanced oxidation (AOP)

ULTRAVIOLET DISINFECTION The TrojanUVFit™ is an UV system from Trojan Technologies for wastewater reuse and high level disinfection applications. The TrojanUVFitTM system is ideal for piped systems and delivers effective chemical-free disinfection in a pressurized reactor. This configuration is well-suited for media or membrane filtered effluent where effluent is already under pressure. The UV system uses low-pressure high intensity amalgam lamps to provide an energy-efficient solution.

The proposed UV system has a compact reactor design which minimizes footprint and headloss while ensuring that maintenance activities such as lamp replacement are is performed quickly and safely. Design Specifications and Power Requirements The design specifications for the proposed UV disinfection system are shown in Table 9 and detailed information/specifications for the proposed UV system are shown in Appendix G. Since the ozone system will be designed for both color removal as well as disinfection, the UV system will be designed and operated at a minimum dose. The UV transmittance (UVT) is expected to be higher (80%) since the water is treated with membrane and ozone before being passed to the UV system. In the event of membrane integrity failure or ozone system failure, the WRF effluent pumps (to the clearwell) will be turned off. Since the MBR and ozonation system (combined) will be designed to meet Title 22 standards, the UV system will be operated at a minimal dose of 40 mJ/cm2.

ODOR CONTROL The new WRF is intended to be a high profile demonstration project. The facility is surrounded by high use public buildings and open spaces. Thus the complete capture and treatment of odors and the prevention of any foul odors from the facility impacting the public is an essential part of making the WRF successful. All odor control systems contain the following elements:

• Ventilation of working areas: • Capture and collection of foul air; • Treatment of the air to remove odorous compounds; and • Exhaust of the treated air.

All four of these elements play a key role in preventing odor impacts to the public.

Regulatory Requirements The following laws and agencies regulate various portions of the odor control and emission process:

• City of Anaheim municipal code – odorous emissions • South Coast Air Quality Management District (SCAQMD) – emissions • National Fire Protection Agency (NFPA) – ventilation of process areas; and • Occupational Health and Safety Administration (OSHA) – ventilation of worker occupied

areas. Chapter 18.48 of NFPA Standard 820 governs operations of recycling facilities. Section 060 paragraph 140 states the following: “All uses shall be conducted in a manner so as not to be objectionable by reason of noise, odor, dust, fumes, smoke, vibrations, or other similar causes.” The NFPA Standard 820 provides standards of ventilation established to prevent fire and explosion within wastewater treatment facilities. The ventilation rates for various areas of WWTPs depend on the type of electrical equipment used in those areas. The Anaheim WRF facility will be completely enclosed in a single building. The anoxic, aeration, and post anoxic areas will be in tanks below the building and there will be openings between the areas the rest of the building. The NFPA ventilation standard for enclosed aeration zones is 12 air changes per hour if the electrical equipment has a National Electrical Code (NEC) rating of Division 2 Class I Group D. If the equipment is rated Division 1 there are no ventilation requirement. While the mixing equipment in the anoxic zones may be Division 1 rated, all of the equipment in the working areas of the building will be Division 2. Thus a minimum ventilation rate of 12 air changes per hour throughout the building may be required. NFPA also has standards for the odor control areas. With Division 2 electrical equipment a minimum of six air changes per hour in the areas out to three feet surrounding any potential leak.

TM-001 Preliminary Process Design August 7, 2009

TM 001_Process_v1.docxocess_V1.docx 21 of 36

Because the odor control area is not isolated from the rest of the facility the12 air changes per hour standard discussed above will govern. OSHA does not provide specific ventilation standards but rather sets limits for worker exposure to specific compounds. In wastewater treatment applications hydrogen sulfide is the most common among these compounds. Worker exposure to hydrogen sulfide is limited to 20 ppm. Most of the process equipment such as the screen and MBR are self contained equipment and will be ventilated. The anoxic, aeration and post anoxic areas are tanks below the floor of the building. The only access to these areas will be through hatches in the floor. This configuration of the tanks and the limited access means these areas must be governed by the rules of confined space entry. Confined space entry requires workers to have respirators and thus the OASHA limits for concentration of hydrogen sulfide do not apply in these areas. As confined spaces these areas will have to be equipped with the following gas detectors and associated alarms located at the entrances:

• Hydrogen sulfide; • Oxygen; and • Methane.

Ventilation and Emission Capture/Collection In addition to the regulatory requirements discussed above there are other considerations in the sizing and arrangement of the ventilation and air collection systems. The foremost concern at the WRF is to prevent odors from escaping the facility and impacting the public in the surrounding areas. Process equipment in the building such as the inlet screen and MBR will be self contained and ventilated. The equipment will have small maintenance hatches that will need to remain closed for operation. Each anoxic and aeration tank will have a single three by three foot access hatch. Each post anoxic tanks will have two of these hatches. At least one of these hatches for each tank will need to be open occasionally and possibly be left open for extended periods. It is vital that enough air be pulled down through the hatches when they are open to prevent odors from escaping. For hatches located inside a building away from suction caused by wind passing over the hatches a capture velocity of 100 ft/min will be sufficient to prevent odor from escaping the tanks. Table 10 outlines the ventilation requirements for the various process equipment and areas as well as the sizing criteria. Detailed sizing calculations for odor control are shown in Appendix H.

the collection fans and treatment equipment (a total foot print of 26’ x 20’ x 10’ high)

520 cfm

Total 6,461 cfm

The total volume of the building is approximately 254,000 ft3. The required airflow to achieve 12 air changes per hour in the building is 4,875 cfm. The air collected from the process areas will need to be gathered from the building in order to provide the capture velocity across the hatch openings. Thus the process air collection of approximately 6,500 cfm is greater than the minimum 4,875 cfm required for 12 air changes per hour in the building. The odor control system will be sized for 6,500 cfm which will provide approximately 16 air changes per hour in the building. In addition to the amount of air collected the location of the inlets for makeup air and the collection points are important. The following are general good engineer practice when locating makeup air inlets and foul air collection points: Whenever possible enclose the odors and collect foul air as close to the odors source as possible;

• Drag fresh air past worker areas; • Avoid pulling foul air past worker areas; and • Avoid short circuiting the collection of odors by placing the collection port too close to

the makeup air inlet. In the proposed ventilation scheme fresh air will be introduced into the building through roof mounted inlets. This air will become the makeup air for the tanks and will be introduced to the tanks through louvered intakes located near the hatches. Air will be collected from the tanks at the opposite end of the tanks from the inlets. Air will also be collected from the inlet screen and the MBR directly. Air will be collected from near the floor in the odor control area. This

TM-001 Preliminary Process Design August 7, 2009

TM 001_Process_v1.docxocess_V1.docx 23 of 36

collection point will be located as far away from the overhead door as possible. This scheme incorporates all of the four elements listed above and will provide vital capture of odors thus preventing them from escaping the facility when doors or hatches are opened.

Foul Air Treatment There is a wide variety of odor control technologies available but these can be grouped into the following general types:

• Absorption filters – carbon and iron sponge filers; • Biofilters – organic and inorganic media filters; • Biotrickling filters and bioscrubbers; • Wet chemical scrubbers; • Chemical dosing of the wastewater; and • Regenerative thermal oxidation.

Of these technologies biotrickling filters, bioscrubbers, wet chemical scrubber and chemical dosing of the wastewater can be eliminated from consideration. Biotrickling filters, bioscrubbers and wet chemical scrubbers generally target hydrogen sulfide with some removal of other odorous compounds. Thus they do not provide the highest level of odor reduction. In this application and location the highest level of odor removal is essential. In addition chemical scrubbers require frequent delivery of caustic chemicals that require operator training and special handling. Given the close proximity to the high traffic public areas such chemical deliveries would be impractical and undesirable. Several different chemicals can be dosed into the wastewater flow to prevent the formation and release of odorous compounds. These chemicals generally target hydrogen sulfide generation but will reduce other sulfide compounds depending on the chemical used. However, as with wet chemical scrubbers, many of these compounds are corrosive or otherwise harmful and require care in handling and storage. Again the proximity of the facility to the general public makes the delivery, storage and use of such chemicals impractical and undesirable.

Treatment Technologies

Iron sponges can also be eliminated from consideration. These filters collect hydrogen sulfide and leave other odorous compounds in the air stream thus not achieving the maximum odor removal. Regenerative thermal oxidizers (RTOs) are very effective in removing a wide range of odorous compounds, however they are seldom used in wastewater application. The foul airstream is wet and relatively cool. The energy required to achieve compound destruction in an RTO makes their cost of operation prohibitive. The two remaining technologies are biofilters and carbon filters. Both are very effective at removing odors but they function very differently. In a biofilter odorous compounds are absorbed into a thin moisture layer on the surface of the media. The compounds are then oxidized by microorganisms in the moisture layer. The byproducts are mineral salts, carbon

TM-001 Preliminary Process Design August 7, 2009

TM 001_Process_v1.docxocess_V1.docx 24 of 36

dioxide and water. Depending on the material used for the media there can be a residual odor from the media itself. This is true of organic media biofilters that are composed mostly of wood or bark nuggets. Biofilter require a relatively large footprint compared to other control technologies. For the Anaheim WRF a minimum footprint of approximately 1,100 ft2 would be required. In addition the media must be replaced every three years and this generally requires the use of earth moving equipment. This type periodic operation is not well suited to the WRF location. In an activated carbon filter odorous compounds are adsorbed onto surface of the carbon media. The media has high porosity which provides an enormous amount of available adsorption surface area. There are three generic types of carbon media, Plain carbon also known as virgin carbon, caustic impregnated carbon and catalytic carbon. Both catalytic and impregnated carbon are treated to improve their ability to remove hydrogen sulfide and thus extend the life of the carbon in airstreams with high concentrations of hydrogen sulfide. Plain or virgin carbon is better suited for light hydrogen sulfide loading and higher VOC removal. Hydrogen sulfide is normally found in the early stages of wastewater treatment. At the WRF most of the hydrogen sulfide would be expected to be released from the inlet screen and the anoxic tanks. These areas represent about 30% of the total air collected in the facility. Thus there is ample dilution of any hydrogen sulfide collected. For this application where maximum odor reduction is required, removal of the greatest number of volatile compounds will provide the best overall odor removal. There are several advantages to carbon filters. They have a small footprint, and are completely enclosed in a vessel. The major drawback to carbon filters is the need to frequently replace the media. However the replacement process is relatively neat compared to that of a biofilter. Table 11 and Table 12 list the advantages and disadvantages of biofilters and carbon filter respectively:

Table 11 - Advantages and Disadvantages a biofilter

Advantages Disadvantages Less frequent media replacement Highly effective odor removal Inexpensive operation

Large foot print Residual odor from media Heavy equipment required for media replacement and replacement is messy More frequent oversight required for irrigation and weed control

Table 12 - Advantages and disadvantages of the carbon filters

Advantages Disadvantages Smaller footprint Highly effective odor removal Completely enclosed Easier and cleaner media replacement

More frequent media replacement Very high media cost but less media required

TM-001 Preliminary Process Design August 7, 2009

TM 001_Process_v1.docxocess_V1.docx 25 of 36

Based on the above analysis the small footprint, enclosed vessels and the neater maintenance make the carbon filter the clear choice for the Anaheim WRF. Exhaust of Treated Air The air exhausting from the carbon filters will be highly treated and have very little odor. However, it must be noted that no odor control system can produce 100% odor free air 100% of the time. There can be upsets in operation normal reductions in removal efficiency just before the media must be replaced. There is a backup unit in place to provide continual treatment during maintenance operation.

The odor control system will be a carbon filter system with plain or virgin carbon media. The system will treat 6,500 cfm. The system will have the following components:

• One duty carbon filter and one standby unit with each unit 10 feet in diameter. The filter will have either two horizontal media beds each three feet thick as shown in Figure 1.1 or a radial bed filter as shown in Figure 1.2.

• One duty fan and on standby fan to collect the foul air and send it through the carbon filter. The fan will be rated for 6,500 cfm at16 in.w.c.

• Due to the limited space available the collection fans will be equipped with inlet boxes to reduce turbulence entering the fan that would otherwise reduce the efficiency of the fan operation.

ELECTRICAL AND CONTROL SYSTEMS This section describes the electrical and control systems for the WRF building.

Incoming Power to the Water Recycling Facility MWH and the City of Anaheim Electrical Staff shall coordinate the work to provide an incoming power feed to the new Water Recycling Facility (WRF) adjacent to City Hall East. The work shall consist of the design and construction of conduits, wires, Motor Control Center, fittings and other necessary appurtenances to furnish an incoming power feed to the site that is in compliance with local City standards and the NEC. The incoming electrical power feed shall originate from the existing Civic Center Main Switchgear located south of the WRF. A 400 ampere circuit breaker, matching the existing manufacturer, shall be installed in the available space within the Civic Center Main Switchgear. The power wiring shall utilize an existing 5-inch conduit that originates from the Civic Center Main Switchgear and runs to the Maintenance Room located in the Parking Structure east of City Hall East. MWH and City of Anaheim Electrical Staff shall determine the exact routing of this existing conduit and coordinate the location of where to intercept this raceway to continue its routing to the new WRF. The incoming power feed shall be terminated at a Motor Control Center (MCC) located within the WRF. The MCC shall be enclosed in a non walk-in NEMA 4X enclosure to prevent the possibility of exposure to water and/or other harsh chemicals that may

TM-001 Preliminary Process Design August 7, 2009

TM 001_Process_v1.docxocess_V1.docx 26 of 36

be present in the building. The incoming power feed, designed by MWH and coordinated with City of Anaheim Electrical Staff, shall power this MCC, which in turn, shall deliver power throughout the WRF and the new Diversion Structure. MWH shall coordinate the proper number and size of breakers, starters and panel boards provided within this MCC. Bus size and approximately 20 percent extra space for future breakers and starters shall be designed to account for future loads at the WRF. Power for the site shall be distributed from the MCC (MCC) in the Electrical Room of the new WRF. Electric power shall be distributed from the MCC to all equipment, valves and instruments located in the WRF and new Diversion Structure. The equipment manufacturers shall provide local control panels with their equipment which house the starters for their respective equipment if possible. Otherwise starters and controls for this equipment shall be located within the MCC. The MCC shall distribute auxiliary power to the WRF via a step down transformer and 120/208, 3 phase lighting panel located within the MCC.

Communications to the WRF All controls shall be hardwired or networked to a PLC within the WRF. This PLC shall be tied into the existing City’s communication system via fiber optic using utilizing TCP/IP (Ethernet) Protocol. The City of Anaheim already has an existing fiber optic network infrastructure. The probable location for network interface will be to City Hall East which will be adjacent to the WRF. Coordination with the City of Anaheim Telecom Group shall determine the exact location for interfacing with the existing ethernet fiber optic system. The fiber optic system shall provide two way communications with City Hall, Lenain Water Treatment Plant and other locations as required. The WRF will be monitored remotely by City staff at the Lenain Treatment Plant via SCADA. Alarms and control notifications will be sent to the Lenain Treatment Plant and elsewhere as required.

Power Feed to Diversion Structure Power to the Diversion Structure shall originate from the MCC within the WRF. The Variable Frequency Drives and controls for these pumps shall be housed within this MCC. Each pump within the diversion structure shall have a power feed in a 1” conduit from the Motor Control Center to a local disconnect switch at the manhole. These local disconnect switches shall be rated NEMA 4X due to the outside environment where they will be mounted. Another 1” conduit shall be routed from the local disconnect switch to each pump within the diversion structure.

Communications to the Diversion Structure

A PLC shall be provided at the Diversion Structure for communication interface with the WRF. The City has standardized on General Electric RX3i PLCs which are capable of direct Ethernet interface. All process parameters and alarms at the Diversion Structure shall interface with City’s network via an Ethernet fiber optic link.

Power Feed to Booster Pump at City Hall West

TM-001 Preliminary Process Design August 7, 2009

TM 001_Process_v1.docxocess_V1.docx 27 of 36

MWH and the City of Anaheim Electrical Staff shall coordinate the work to provide power to a small booster pump. The booster pump is responsible for boosting pressure to the toilets on floors 2 through 11 in the City Hall West Building. There are two options to provide power to this pump. The first option is to provide a starter in the existing Motor Control Center MCC-A, located in the basement of the City Hall West Building. New conduit and wire shall be routed from the Motor Control Center MCC-A to the booster pump through the ceiling. The controls for this pump would be located at MCC-A. Another option would be to install a 480, 3-phase breaker in Panel board LSLB located in the basement of the City Hall West Building, and route new conduit and wire to a Local Control Panel near the pump. The controls for this pump would be housed in this Local Control Panel.

Communications to the booster pump station A PLC shall be provided at the Booster Pump Station for communication interface with the City Hall West. All process parameters and alarms at the Booster Pump Station shall interface with City’s network via an Ethernet fiber optic link. The fiber optic link will probably interface directly to the nearest Remote Terminal Unit (RTU) in City Hall West. Coordination with the City of Anaheim Telecom Group shall determine the exact location for interfacing with the existing Ethernet fiber optic system.

STRUCTURAL CONSIDERATIONS The City of Anaheim has formally adopted the 2007 California Building Code (CBC) with City specific amendments. The structural design of RWBR WWTP will be governed by these codes. In specific, the following list of codes will be used by MWH to complete the detailed structural design.

• Concrete – ACI 350-06: Code requirements for Environmental Engineering Concrete Structures

• Masonry – ACI 530-05: Building Code Requirements for Masonry Structures • Steel – AISC 13th Ed: Steel Construction Manual

The geotechnical design requirements and recommendations are forth coming. These requirements and recommendations will set forth the design criteria lateral soils pressures, allowable soils bearing pressures and the general site-specific Seismic design parameters. The RWBR WWTP is to be constructed on the North-East corner of the existing City Hall building. It will be placed in between the existing City Hall building and an existing electrical duct bank. The new WWTP will be approximately 20 feet from the North wall of City Hall. This close proximity to the existing City hall and the electrical duct bank will introduce some challenges during the construction phase of the project. Based on the limited information provided in the pre-design report, the construction excavation for the WWTP is expected to extend below grade approximately 20 to 25 feet. Specially designed shoring will need to be designed and installed to limit any settlement of the existing building, interruption of the electrical duct bank and to keep the soils in place between the existing building and the new

TM-001 Preliminary Process Design August 7, 2009

TM 001_Process_v1.docxocess_V1.docx 28 of 36

APPENDIX C

Information and Specifications for Fine Screen

The Waste Tech Rotating Drum Screen incorporates a feed distribution headbox for effective flow distribution and an internally screw auger with individual dewatering cells which dewaters and transports the separated solids out of the drum. Depending on the size of the screen the drum is direct drive, cog gear drive or trunnion driven. The influent is controlled into the drum by means of various inlet pipe designs, selection based on the type of material processed, which distributes the influent over a large area of the drum to ensure efficient use of the drum open area. As the drum rotates fluids pass through the perforations and forward to treatment. Solids are removed and dewatered from the drum by the fixed transport screw.

The Perforated Screen is effectively cleaned by means of a friction drive rotating brush and intermittent spray system. The Waste Tech RDS is fully enclosed with removable inspection covers to prevent splashing and leaks and are designed to create a hygienic working environment in the area the screens are located and comes standard equipped with a pipe connection for odor control.

When combined with our screenings washer press fitted with drainage perforations matching the drum perforation we can guarantee matching capture efficiency of solids to prevent bypass of solids to the downstream process. Screenings are washed and compacted to 80%+ volume reduction

Special Features:Automatic Integral Overflow System (IOS) with alarm indication to prevent dirty influent from contaminating the filtered effluent. Separate overflow connection allows dirty flow to be diverted to back to the pump station.

IOS System automatically activates spray system with hot or cold water to wash away biological slimes, grease, etc….

Various influent distribution pipe designs for specific applications

The enclosed perforated drum screen has no seals or slots – all flow must pass through the perforations – therefore we can guarantee no bypass or carryover of solids to the downstream process.

Special perforation design and cleaning system allow perforations down to 0.6mm guaranteed not to clog with screenings.

Low water usage due to special designed drum cleaning system – water is the secondary cleaning method, not the primary cleaning method

Perforated drum available from 3 mm to 0.6 mm

The Waste Tech RDS stainless steel perforated drums are stronger and more efficient than wedge wire or mesh drum screens

Operator Safety – all rotating parts are covered and the unit is totally enclosed to prevent contact with material.

All removable covers are bolted down or fitted with safety switches to detect removal

Combined with our screenings washer press provides a complete high performance screenings capture, washing and dewatering system

Special Applications:Membrane Biological Reactors (MBR)Effectively removes short chain fibers that create ropes which hang on the hollow fiber membranes and reduce efficiency causing frequent back flushing and failure of the membranes.

Waste-Tech RDS with 1 mm perforations are ideal for screening raw sewage ahead of MBR plants. Waste-Tech RDS efficiently remove up to +95% inert solids, including fibers and hair. Waste-Tech RDS with 0.6 mm to 3 mm perforations offer flow capacities up to 50 mgd (larger capacities available).

Guarantee no carryover of solids

Sludge ThickenerBy adding polymer to waste activated sludge (WAS) or mixed primary and secondary sludges, a Waste Tech RDS can dewater the sludge from 0.5 -2% DS to 4-10% DS. This will save money on less transport or by using a lower capacity belt press.

Typical ApplicationsThe Waste Tech RDS is also used in a variety of other applications including: - Raw Sewage Screen, Sludge dewatering, Pulp and Paper Mills, Fiberglass, Poultry, Fish Processing, Vegetable Preparation, Slaughterhouses – any application requiring liquid solids separation between 0.6 mm to 3 mm

All models are of stainless steel and have the following options:

optional hole perforation from 0.6 mm (0.02 inches) to 3 mm (0.12 inches)varying types of inlet pipes for water or sludge with or without overflow system varying speeds variable inclines available low weight and small footprint low energy consumptionlow water usage304, 316 stainless steel – special alloys available hygienically encased with optional ventilation connection

APPENDIX E

Information and Specifications/Warranty for Norit/Dynatec Membrane System

Municipal Waste WaterChallengeMunicipal waste water needs to be treated as it originates exactly

there where people live. The treatment should be done as close as

possible to the source. With growing cities the footprint of these

plants and the quality of effluent needed have given more and more

interest in compact waste water treatment plants.

In a growing number of plants submerged membranes are applied to

improve them to Membrane Bioreactors (MBR). However cleanability

and maintenance are not ideal in these plants, as the membranes are

difficult to reach. Uniform distribution of membranes and the ability

to reach every square meter of the membrane area are essential for

optimal operation and keeping a plant running satisfactory.

SolutionThe X-Flow’s AirLiftTM configuration offers a membrane solution out-

side the reactor allowing the maintenance of the plant to be simple

and clean. Due to the inside out configuration of membrane filtration

all membrane area is subject to the same process conditions.

Energy consumption is at the same level of submerged membranes

or even less, due to the efficient usage of process conditions for

flux enhancement.

X-Flow’s tubular 5 mm UF membrane will allow a bioreactor to

run up to 15 g/l MLSS biomass.

X-Flow’s 5 mm tubes found their way in MBR applications in the

municipal and industrial market in areas such as:

• Municipal WWTP

• Food industry

The X-Flow tubular membrane modules are being produced with

ISO 9000 certification.

Appendix A2 Compact, Pro-rated Lifetime Warranty Conditions

Page 1 of 2 2008 rev7

1. Membrane Element warranty

There is no other warranty express or implied as provided for herein.

X-Flow warrants that its membrane elements supplied shall be free from defects in materials and workmanship. The membrane element warranty for lifetime will commence upon

installation of the membrane elements in the UF system or three months after the date of membrane element ready for shipment ex works Enschede, The Netherlands, whichever comes first. X-Flow’s sole liability and the Purchaser and/or Owner exclusive remedy under this warranty shall be to provide replacement membrane elements

and is limited to the initial membrane element contract value. Any membrane element found to be defective under the terms of this warranty during the first 12 months of the warranty period will be replaced at no cost to the Purchaser and/or Owner, excluding shipping and handling

charges

Any membrane element found to be defective under the terms of this warranty after the initial 12 months of the warranty period will be replaced

based on the pro-rata membrane element value as calculated below, excluding shipping and handling charges.

Pro-rata membrane element value:

Membrane element Replacement Price* X Months Beneficial Use Total membrane element Warranty Period (months)

The Membrane Replacement Price is based on the actual list price at the time of replacement or otherwise agreed upon.

The months of beneficial use will be calculated based on the calendar month of the warranty claim relative to the commencement of the warranty period.

The membrane element warranty period is 36 months or otherwise agreed upon.

2. Membrane Element Failure Criteria A membrane element shall be considered defective if it meets one or more of the following criteria:

An individual membrane element shall be considered defective;

• if more than 5 of the total number of membrane tubes in the

element have required repair (i.e.: by plugging, pinning and/or gluing) during any consecutive period of 12 months

• if more than 10 of the total number of membrane tubes in the element have required repair (i.e.: by plugging, pinning and/or gluing) over the total course of the warranty period.

Note: Tubes repaired during production and testing are excluded from the failure count. Tube repair on site is the responsibility of the purchaser and or owner. 3. General Warranty Conditions

All warrantees shall be null and void if any of the following conditions are not met:

a) Accidental and/or external caused damages and damages caused by

improper use are excluded from this warranty. Accidental and/or external caused damages and damages caused by improper use are damages

caused by but not limited to operation and/or exposure of membranes modules to conditions, outside the instructions and conditions listed in the X-Flow Product Datasheets or misuse, abuse or improper installation,

operation, maintenance, or repair, alteration, accidents. Also, damages caused by uncontrolled and/or defective operation of the overall water

treatment process in which the membrane elements are used or parts thereof are excluded from this warranty. This warranty is strictly limited to

membrane failure due to X-Flow’s fault in manufacturing; all other

causes are excluded. If there is any dispute with respect to the above, the Purchaser should provide evidence to X-Flow.

b) The Purchaser and/or Owner of the membrane elements will immediately notify X-Flow in writing of any potential issues or claims relating to the membrane element warranties.

c) The feed and/or backwash stream to the element(s) shall contain neither organic nor inorganic matter or solutions harmful to the membrane elements as listed on the X-Flow Product Datasheets and/or X-Flow Chemical Resistance Datasheet (see appendix B). Also fiber damage due to foreign debris is excluded from this warranty. d) Membrane elements shall be handled and stored according the instructions on the X-Flow data and instruction sheets. e) During normal operation the membrane element(s) shall be protected against the introduction or intrusion of any and all gasses

(i.e.: air) unless the entering of gas is required and/or allowed during certain controlled process steps / sequences, such as but not limited to air-flush, airlift or integrity tests. f) The membrane element shall be operationally protected against

hydraulic and pneumatic shock loading such as, but not limited to water hammer, etc. g) X-Flow understands that the membrane elements will be used as a part of a larger water treatment process. X-Flow must be given the opportunity, with a reasonable notice, to review engineering

documents and attend testing and commissioning activities of all aspects of the water treatment process which may affect membrane

lifetime. Note: That neither a review of the engineering documents nor attendance of testing or commissioning nor the declining of the opportunity does constitute any responsibility for any aspect of the

system. h) The purchaser and/or Owner will calculate and record the temperature-normalized clean membrane permeability after each membrane element cleaning for the duration of the membrane

element warranty period and any subsequent extensions. The Purchaser and/or Owner will immediately notify X-Flow in writing of any recorded drop in temperature-normalized clean membrane permeability of greater than 10% of reference permeability value. The notification shall include all pertinent treatment process and

operating parameters at the time of the reading. Purchaser and/or Owner should avoid scaling or fouling of membranes at all times. i) The Purchaser and/or Owner of the membrane elements will maintain for the duration of the warrantees complete and accurate

daily records of all relevant process settings and data (see Appendix C, “Trending and Logging”). Copies of these data shall be made

available to X-Flow upon request. j) Any defects or faults caused by any alterations to the membrane elements, or improper use or mishandling of consumable items used in the operation of the membrane elements, by the Purchaser and/or

Owner or his authorized representative are specifically excluded from this warranty. Furthermore any replacement of X-Flow membranes by

membranes not produced and/or supplied by X-Flow will render this warranty null and void.

k) In the case where the Purchaser and Owner are separate parties, the Purchaser has sole and exclusive responsibility for making the Owner aware of his responsibilities under the conditions of this warranty. Failure of the Purchaser and/or Owner to meet their respective obligations under this agreement will render this warranty

null and void.

4. Conditions for Testing and Shipment

a) X-Flow reserves the right to test and verify the failure of any membrane element for which a warranty claim is made. b) Membrane elements shipped to X-Flow for warranty examination must

be shipped freight, tax and custom duties prepaid.

c) Before returning any membrane element(s) to X-Flow for warranty

examination, X-Flow must be contacted to obtain return authorization. For that purpose, follow X-Flow’s return procedure which can be found on our website (www.x-flow.com). Any element(s) shipped to X-Flow without

return documentation will be returned to shipper unopened, freight collect.

d) If after the testing the failure of the membrane element is determined to be caused by the Purchaser, the Purchaser shall pay X-

Flow all damages and expenses such as but not limited to: costs for testing, reports, site visits, etc.. e) Membrane elements examined as part of a warranty claim, which

are found to be performing as warranted will be returned to the Purchaser freight collect and a handling charge will be levied against the Purchaser.

Information and Specifications for UV System

WASTEWATER DISINFECTION FILTERED IN-PIPE TREATMENT

Around the globe, wastewater treatment plants of all sizes are responding to the water quality and quantity demands of the communities they serve. As more municipalities adopt wastewater reuse policies and practices, wastewater treatment plants are required to treat effluent to higher levels –essentially eliminating all pathogens prior to reuse or discharge. Depending on site and design conditions, wastewater treatment plants producing

filtered effluent sometimes prefer a disinfection solution using closed-vessel or pressurized UV reactors. The TrojanUVFit™ offers an effective and energy-efficient closed-vessel UV solution. This compact reactor is available in multiple configurations to treat a wide range of flow rates. The streamlined hydraulic profile of closed-vessel systems disinfect filtered effluent without breaking head in the treatment process. These benefits along with UV’s ability to provide environmentally-friendly, chemical-free treatment for chlorine resistant microorganisms (such as Cryptosporidium and Giardia) make the

TrojanUVFit™ closed-vessel solution an attractive option for wastewater disinfection.

Trojan Technologies is an ISO 9001:2000 registered company that has been leading the UV disinfection market with open-channel solutions for wastewater disinfection (e.g. TrojanUV3000Plus™) in over 5,000 municipal installations worldwide – the largest UV installation base. The TrojanUVFit™, the latest addition to the Trojan product line, rounds out a complete portfolio of products for wastewater disinfection and reuse applications.
