SMART YELLOW IS THE NEW GREEN

INTELLIGENT HIGH RATE FLOTATION UNITTAKING PRE-TREATMENT TO THE NEXT LEVEL Currently, efficient pre-treatment solutions for sea, surface, and wastewater are a major theme in the industrial and municipal water treatment markets. The rise of membrane filtration technology applications has presented companies with new challenges: to minimize costs (membranes and energy) and system failures. The “Intelligent High Rate Flotation Unit” is a SMART solution that guarantees maximum and efficient solids removal, taking pre-treatment technology to the next level. Especially for the purification of sea and surface water, pre-treatment solutions have to be compact, robust, stable, and modular at the same time.

Our clients benefit from three major improvements:1. High quality membrane feed water due to robust and reliable removal

of solids.2. Low CAPEX compared to alternative pre-treatment, thanks to - Low civil cost due to compact and small footprint. - Standardized production.3. Low OPEX compared to alternative pre-treatment, thanks to

- Low energy consumption. - Low sludge treatment cost by enhanced sludge thickening.

The Dissolved Air Flotation technology (DAF) has proven to be very successful as a pre-treatment step. Nijhuis flotation systems have been developed since the 1970s and our pre-fabricated stainless steel units stand out as the best in its field. However, above 1,500 m3/h and by extreme wastewater conditions concrete solutions are more economical. Our experience tells us that the expenses of transport and the application of appropriate stainless steel are often too significant above this capacity.

The next generation of flotation units is developed by a multidisciplinary team at Nijhuis Industries, combining the civil and hydraulic engineering of NH2OK and innovative wastewater technology from Nijhuis Water Technology. It is with pride that we present the Intelligent High Rate Flotation Unit (IHRFU), a concrete based high rate flotation unit, corrosion resistant, built with proven Nijhuis technologies. The Intelligent High Rate Flotation Units are typically applied at large scale water production facilities to remove solids from surface and seawater. Medium and large scale municipal and industrial wastewater treatment facilities apply our technology as pre-treatment prior to subsequent biological treatment. The solution is based on smart modular sections of 1,500 m3/h, each incorporating innovative and efficient coagulation, flocculation and flotation functionality ensuring a compact design and lowering the environmental footprint. To meet quality requirements, the intelligent high rate flotation unit can provide a NTU of < 1 depending on water source characteristics.

Unique integrated aspects are the specially designed Nijhuis plate packs and optional Nijhuis bottom scrapers which allow for higher capacity and solid loading. The Nijhuis plate packs reduce footprint requirements by 50 – 75% compared to a conventional DAF without plate pack. The fine Nijhuis bubble aeration system guarantees lower energy consumption up to 30% per m3 water. The Nijhuis smart level control reduces sludge disposal costs by ensuring high and stable dry solids content. Furthermore, the level control offers operational flexibility by anticipating on fluctuating flows without loss of solid removal efficiency. These useful features significantly reduce operations time and maintenance costs.

In comparison to conventional sedimentation technology, the Intelligent High Rate Flotation Unit is able to remove over 99% of algae and over 95% of oil and grease ensuring maximum protection of any post-treatment technology. It is a great example of the synergy between the different Nijhuis Industries companies and their expertise. Nijhuis developed the next level of pre-treatment technology by using intelligent and smart features to manage large water capacities and reduce our clients’ total cost of ownership. Our smart techniques for large water flows have been combined with the company’s long term DAF experience.

Wilbert Menkveld, Research & Development Manager, on the Intelligent High Rate Flotation Unit“Nijhuis Water Technology has supplied more than 2,400 complete DAF systems worldwide with a treatment capability of 2 to 1,500 m3/h. During the last couple of years the market has been showing a growing demand for larger systems for the pre-treatment of surface and wastewater. Stainless steel DAF installations are manufactured up to 1,500 m3/h. Larger capacity systems are available as well, however, logistics and transportation expenses are too significant and often have a negative impact on the project costs. With the introduction of the Intelligent High Rate Flotation Unit, Nijhuis found an answer to the larger capacity requirement. It consists of smart modular blocks of 1,500 m3/h, each incorporating innovative and efficient coagulation, flocculation and flotation. The new Intelligent High Rate Flotation Unit has a substantially lower energy consumption up to 30% per m3 due to smart Nijhuis aeration control while the smart Nijhuis level control reduces disposal costs by ensuring higher and more stable dry solids content. We are proud to have developed this new Intelligent DAF and support the introduction of the Intelligent High Rate Flotation Unit to the global market”.

AECOMIXTM: TURN YOUR WASTE AND WASTEWATER TREATMENT PLANT INTO A POWER PLANT

The AecomixTM is a revolutionary and highly innovative solution, especially tailored to food and beverage plants treating wastewasters with high TSS and/or FOG. Additional benefits can be realized when the plant is designed to treat factory waste as well. The concept provides a single step process solution for different substrates with a high removal efficiency (of organic matter) of more than 95% on COD. Since the majority of removed organics is transferred into biogas, a much higher biogas

volume is achieved in comparison to process steps.

In case post-treatment is required, this step will be less intensive in comparison to the traditional method because more organics will already have been removed in the AecomixTM process. This results in a smaller footprint and less OPEX for polishing. Wastewater can be fed directly to the AecomixTM if coarse solids are present that need to be macerated. The (solid) waste streams may need pre-treatment such as shredding, maceration or pasteurization before feeding them to the AecomixTM. The challenges typically concern waste with a high organic load and a low(er) dry solids content, such as: whey, sugar, waste from snack food production and glycerine. It is a perfect solution to deal with factory effluent together with organic waste without the need of chemical pre-treatment. Typical examples of such industries are chocolate, ice cream, dairy and vegetables and fruit.

AecomixTM factors of excellence• A single step process solution to convert a mix of

wastewater and organic waste in one anaerobic reactor into an energy source.

• No pre-treatment required resulting in lower OPEX. • Highly adaptable to local requirements and conditions.• Simple and stable process.• Use of proven technologies like digestion and dissolved

gas flotation.• Less intensive biotreater resulting in a smaller footprint

and les OPEX for polishing.

MUNICIPAL CONTAINERIZED SOLUTIONS: INDUSTRIAL DESIGN APPROACH FOR THE MUNICIPAL MARKET

The Nijhuis containerized municipal solutions range provides a variety of fully equipped wastewater treatment plants based on high quality and reliable technologies and materials. Due to the modular design the Nijhuis containerized solutions can be easily relocated or modified. They have a capacity that ranges from 2 to 20,000 m3/d. Subject to the influent load and effluent discharge limits, various process steps can be connected to comply with the required treatment level. In some cases only pre-treatment is sufficient, however, if high removal rates are required, multiple steps can be connected resulting in a high-end wastewater treatment system to meet the stringent discharge limits.

The system’s strength lies in its compact footprint, fast track project realization, reliable material, sustainable technology, lower operational and investment costs. In case future changes require an increased level of treatment or extended hydraulic capacity, the units can be easily extended without significant civil activities on site due to its modular set-up. The distinctive advantage of containerized solutions is based on the development of highly cost-effective integrated solutions that cover all required treatment stages and corresponding equipment. Together they offer a tailored package to our clients to meet individual requirements in the most effective and professional way.

Every treatment stage takes place in pre-engineered stainless steel containers, tanks and equipment, arranged in accordance with capacity and required treatment quality. These are designed for above-ground installation with additional air-conditioned administration, staff and support facilities available as well. Smaller capacity units of up to 200 m3/d can be positioned below ground.

The mining industry is considered as one of the most dynamic markets for water and wastewater treatment technologies and related services. Copper for example is mainly used in jewelries, machine factories, automotive production and construction sites. Nijhuis Industries LATAM, in cooperation with their local agent Spena, recently received the order for a pre-treatment system for Cerro Verde.

The majority of the shares from Cerro Verde–Latam are owned by American-based company Freeport MacMoRan Inc. (FCX). The Cerro Verde mine has various wastewater streams, which vary both in flow as well as pollution-loads, thus demanding equalization-systems to balance-out the fluctuations involved. The requirement for TSS-level after pre-treatment is more than 90%.

To control the whole operation, the effluent is continuously monitored using an infrared NTU-measurement. Furthermore the electrical controls have to comply with high standards, UPS installed for power supply-failures, connected to MCC-panels and provided with Ethernet for communication with main control rooms. The system is expected to be commissioned during the first half of 2015 and aims to lower disposal costs and meet the ever demanding sustainability requirements.

THE NIJHUIS HERITAGE - FROM 1904 UNTILL 2015

110 years ago, Gerrit Jan Nijhuis started a small machine factory in Winterswijk, located in the east of the Netherlands. G.J. Nijhuis was born in 1877 in Boekelo and grew up on a farm called “den Els”. After having discovered his talent for forging and repairing machines he established “Machinefabriek (Machine factory) Nijhuis-De Wolf” together with his business partner Mr. Wolf in 1896. After eight years their partnership came to an end and on 5th of April 1904 he started “Machinefabriek (Machine factory) G.J. Nijhuis” on the Parrellelweg in Winterswijk. The workshop offered repairs for textile, dairy and slaughterhouse equipment. In 1917 he expanded the factory with a foundry which enabled the company to design its own generators, motors and other iron equipment.

During the mid-twenties the company gradually applied more focus on designing and manufacturing slaughterhouse equipment. In 1927, Nijhuis provided the local slaughterhouse in Winterswijk with the latest state-of-the-art slaughterhouse technology, a unique piece of equipment in the Netherlands back then. In the 1930s Nijhuis introduced a new division aimed at repairing, designing and manufacturing Nijhuis pumps. G.J. Nijhuis proved to be a great inventor and was personally responsible for the introduction of the self-priming centrifugal pump. Nijhuis pumps continued to grow in popularity, particularly in the shipping and fire pump industry where the Nijhuis name became a household brand for decades. After World War II the population of The Netherlands was on the rise again which had an impact on the demand for food and slaughterhouses. This development in combination with the company’s engineering experience encouraged Nijhuis to continue to expand and build a reputation for itself in the field of pumps and slaughterhouse equipment.

The growing demand for the purification of wastewater in slaughterhouses in the sixties and seventies led to the development of the Augias bandfilter and flotation system. Capable of separating solids from slaughterhouse wastewater, the newly developed system was able to meet the discharge requirements imposed by the government. The flotation system was an idea originally inspired by the oil industry. In 1977, Machinefabriek G.J. Nijhuis employed 200 employees active across three divisions: Pumps, Slaughter Technique and Wastewater. Each division had their own symbol and specialized in the engineering, manufacturing and delivery of products across a wide range of industries. The idea behind the company’s logo, showing the Nijhuis eye was also established during this time. It meant to visualize “a critical eye on water treatment”.

The foundry in Winterswijk

To allow the company to specialize further and meet the growing demand for purifying wastewater, Nijhuis started the Nijhuis Water division, aimed at developing wastewater technologies to accommodate for a new range of other markets at the end of the seventies and eighties. The GDF (the Gerrit Drupsteen Flotation unit) and IPL (Inclined Plate Lamella separator) where developed during this period, as well as the temporary wastewater rental solutions. In 1983 Nijhuis Slaughterhouse technique moved to Lichtenvoorde and Nijhuis Water B.V. relocated to the Rondweg (Hal Zuid) in Winterswijk with its own production facility. Throughout the mid-eighties Nijhuis Pumps was separated all together which resulted in Nijhuis Water and Nijhuis Slaughter Technique to operate as separate entities.

The Nijhuis eye

THE NIJHUIS HERITAGE - FROM 1904 UNTILL 2015Nijhuis Water continued to expand its wastewater technologies in primary and secondary treatment all over the world under the leadership of G.J. Nijhuis, grandson of the original founder. He was director of Nijhuis Water from the late seventies until 1990. In 1987 Stork acquired Nijhuis Slaughter Technique and after five years the former relationship between the three divisions came to an end. It was also at that time that the business started operating in Poland. In 1993 Nijhuis Water moved from Winterswijk to Dinxperlo with approximately 40 employees under the new name “Nijhuis Water Technology” (NWT). The Dinxperlo office provided Nijhuis with its own production facility for the in-house production of robust stainless steel wastewater solutions such as the famous dissolved air flotation system.

The Dinxperlo era introduced a whole new range of added values services like engineering, project management, manufacturing and service of complete wastewater treatment systems. The company’s expertise continued to grow across a wide range of industries, especially in the oil and gas market where the famous Nijhuis flocculation-flotation technique was based on the latest safety standards.

At the beginning of 2000, the demand to create value out of waste material was growing. To accommodate for this requirement Nijhuis developed the first concept of the AecomixTM in Lithuania. In the years that followed waste to value continued to develop itself as an important new theme in the industry. Between 2005 and 2010 Nijhuis opened new offices in Russia and the USA and established a joint venture agreement with H2OK in the United Kingdom. Not only primary treatment and secondary treatment where important for the complete delivery of wastewater treatment plants, Nijhuis also developed its own Sand Filter and Carbon Filter for tertiary wastewater treatment and an inside fed rotary filter for primary treatment.

2010 witnessed the start of a new period through the acquisition of Thecogas, aimed at expanding the company’s biogas activities to create more value out of waste(water). After a period of 18 years, the Nijhuis logo changed from blue to black and yellow but the ever watchful eye, which has been unique to the Nijhuis identity since the 1970s, continued to exist as it still does to this day. With the appointment of Menno M. Holterman and Ronald Ruijtenberg Nijhuis has been accelerating its growth strategy turning (waste)water into value. In 2013 Nijhuis acquired Excellent Ozone Solutions (now Nijhuis Ozone Solutions) and H2OK (now Nijhuis H2OK) to expand the Nijhuis group with ozone and disinfection technology and turnkey solutions.

In November 2013 a new corporate identity was launched incorporating Nijhuis Water Technology, Nijhuis Ozone Solutions and Nijhuis H2OK under the joint flag of Nijhuis Industries, providing “solid solutions in a fluid world”. In order to cope with the growing demand for Nijhuis systems, solutions and added-value services Nijhuis relocated to its current HQ in Doetinchem. In 2014 new offices were established in Latin America, Singapore and China and at the end of the year Nijhuis Ozone Solutions relocated from Eerbeek to join the team in Doetinchem.

These days Nijhuis has established itself as a multinational and leading solution provider with more than 50 partners and agents all over the world, employing over 240 employees and offices in The Netherlands, UK, Poland, Germany, Russia, Ukraine, China, Singapore, Indonesia, USA, Canada and Colombia. Even though

the former ties with Nijhuis Pumps and Nijhuis Slaughter Technique do not existent anymore, the legacy is not forgotten. The company continues to build on the knowledge and experience that is part of its proud heritage, dating back more than 110 years. It has provided the business with a wealth of expertise based on their innovative vision, in-house technologies, market experience and a wide range of added value services.

We strongly believe that through combining our longstanding expertise and know-how we can design, manufacture and deliver solid solutions with the highest level of innovation to meet today’s challenges as well as those of the future. It is with this vision that we strive for solid solutions fit for a fluid world, ever-changing and variable as ours, just like Gerrit Jan Nijhuis had in mind when he started his workshop all those years ago in 1904.

THE NH2OK HERITAGE FROM THE RIVERS TO THE SEA . . . In light of the Nijhuis Industries heritage feature and the forthcoming 20th anniversary of NH2OK, Phil Badger (original founder) and Tim Cunliffe (current MD) met up at the Headquarters in Truro to turn back time and talk about the early days of the company and the developments since they first joined forces 20 years ago. Originally founded as a consultancy and sewage treatment specialist, the company has seen rapid expansion throughout the years which eventually led to the merger with Nijhuis to become a leading solutions provider in the water and renewable energy market.

13

Phil, can you take us back to the early days of the company?

Phil: “After a number of years in the water industry sector I went self-employed in 1995 and started H2OK as a consultancy specialist. It was the first opportunity to set up a consultancy section to feed the newly privatised water sector in the UK. At that point it was only my wife and I running the business, sharing a room in somebody else’s office right in the centre of Falmouth (Cornwall). The company soon moved to Barkley Vale, our new premises which gave us two offices – luxury that was! A year later, Tim Cunliffe joined.”

How did you come up with the name H2OK?

Phil: “After a number of brainstorm sessions, it was actually my wife who came up with the name of H2OK. It started with the H2O part to which the OK was soon added. In the early days at Berkley Vale our strapline was very much Cornwall inspired, we were called “H2OK – from the rivers to the sea”. We wanted to make a link between our wastewater treatment work and the county of Cornwall, ever intertwined and connected with the sea.”

How did the expertise in the company develop itself?

Phil: “Well, the sewage treatment work that the company does now is not much different from how it started; we still work with the same clients and are recommended by the same people.”

Tim: “There was one job which is the DNA behind our development as a company and the association with Nijhuis: Tulip Foods in Bodmin, formerly known as Roche Foods. They presented us with a £30 million factory that was in need of a wastewater treatment plant: a completely new challenge! That really was the foray into the food sector after which more projects followed.”

Phil: “Another significant step in how we expanded to what we are today is when Tim Sullivan (current principal design manager) joined in 2000 as a result of that first Tulip project. He brought a whole raft of skills with him including design skills, structural engineering and sea defence.

Tim Sullivan played a key part in growing the consultancy section and has established a team

around him throughout the years.”Tim: “After the company moved to Indian Queens the business experienced significant expansion and turned limited in 2003 under the name of H2OK Water and Energy. It outgrew its former location and eventually settled into the current head office in Truro.”

How did the company move into the AD sector?

Tim: “The company was given credibility in the AD sector through its experience in the food and beverage market. One of our major breakthroughs was the biogas project for InSource Energy. It originated from some design work Tim Sullivan had done on a biogas project for Envitec Biogas who were also looking to win a project for In Source Energy. They recommended H2OK to the client who awarded the contracted to us as principal contractor.”

How did the relationship with Nijhuis develop?

Phil: “It was lucky coincidence actually. Around 2005 I noticed an advert in a trade magazine that promoted the Nijhuis DAF unit which caught my eye immediately and a meeting was set up. The first major project was carried out at Tulip Foods Ebinezer and a joint venture partnership was formed in 2010 to supply nationwide anaerobic digestion, waste to energy, wastewater treatment and recycling solutions. That was the courtship that eventually led to the marriage and the rest is history . .

In conclusion Phil added: “When I think back to when we started the company all those years ago and realize that it is now part of a multinational company with lots of prospects – you couldn’t wish a better outcome for your business you started on a shoestring from day one!”

OZONE TECHNOLOGY IN THE DAIRY INDUSTRY

Challenges and concerns in the dairy industryThe dairy industry continues to apply more focus on the importance of reducing water cost and the recovery of valuable materials. Water consumption in this industry is mainly associated with cleaning operations, cooling water and process water. The concerns for health and environmental challenges have given rise to alternative solutions for disinfection. Combining wastewater and waste streams will take the dairy industry to the next level towards self-sufficiency and enable the production of power, energy, fertilizer and recycled water to create value out of waste and wastewater.

Process water in the dairy factoryWhen taking a closer look at the dairy factory process, it is a common fact that process equipment has to be cleaned and disinfected several times to

comply with hygienic regulations. Cleaning is usually related to pipes, tanks and vessels. Most companies apply the conventional method of using chemicals and disinfectants for cleaning purposes which are subsequently discharged to the sewer, using a large amount of fresh water to dilute the chemicals in the water. Pasteurization, sterilization and evaporation lines for example need to be free of bacteria at any time to guarantee food safety. The presence of heated water and product spills in process water is an ideal environment for bacterial growth. Any recycled water flows are susceptible to pollution and bacterial growth as well due to the circulation of warm water streams which are exposed to air for cooling purposes. In order to remove these undesired side effects that arise from the cleaning process, ozone technology provides a chemical-free solution. It helps lower the environmental footprint, reduce water costs and achieve numerous sustainable and economical goals.

Chemical free disinfection by ozone technologyOzone was first identified by German chemist Schönbein in 1865 who noticed a distinct smell while investigating the electrolysis of water. He identified the source and named the gas ozone from the Greek word ‘ozo’ meaning ‘smell’. The chemical identity of ozone (O

3) was identified by Soret in 1865, the result of which was confirmed shortly before Schönbein’s death in 1867. Although the basic technique is still the same, the technology has progressed Ozone (O³) removes bacteria and has the added advantage that hazardous biocides or chemicals are no longer required in the process (O

³ re-generates to harmless O²). Ozone leaves no chemical residues in the water and therefore the water can be recycled multiple times.

Ozone Technology for process and ice water - an example The Netherlands is renowned for its black and white Holstein Friesian cows and the excellent milk they produce year around. Vreugdenhil, based in Gorinchem, the Netherlands, transforms this high quality milk into milk powders and other dairy ingredients. Cooling water in the factory is used to cool the milk product which has to be kept clean at all times. Nijhuis Ozone Solutions provided an ozone installation type NOS Q120 to disinfect cooling water without the use of additional chemicals. The NOS installation has to be able to operate in an efficient, safe and sustainable way to remove pollution and bacteria. In addition to this, the Nijhuis online monitoring program will enable to act and react on reports and alarms to optimize the process. By reading out the collected data of the system, Nijhuis can adjust the process remotely and see when it is time to replace parts to improve the reliability of the plant, optimize the process and lower operational cost.

NOS also delivered a solution to disinfect the evaporated condensate of the milk powder production. Normally the condensate is left unused and discharged to the sewer but in this case, ozone disinfection allowed the condensate to be re-used, resulting in huge savings. The temperature of the condensate varies between 11°C and 40°C. Given the operational circumstances the use of ozone as an oxidant is the right choice for the cleaning and disinfection of CIP and cooling water with environmental benefits as opposed to other sanitizers.

BIOGAS PLANTS ARE THE ANSWER!The main purpose of waste to value projects is to solve waste challenges. There are many types of different waste, which can, and should be ma-naged in different ways. Typical examples of waste streams are: sludge from municipal / industrial wastewater treatment plants, animal manure (liquid and solid), organic waste, food waste and green waste (grass, leaves etc.).

No industry is waste freeThere is no industry that is entirely waste free, all farms and food factories dealing with for example dairy, meat, vegetable and fruit processing plants are producers of organic waste. They are all potential industries for a waste to value project; it could be a single biogas installation for a meat processing and rendering plant, or one central plant for a whole community, where several factories deliver their organic waste. There are numerous possibilities of which two are described below.

What results could be achieved Modern waste to value installations are regarded as “green cleaners” using organic waste which is converted into valuable goods. For example, biogas plants can produce the following:

• Electricity.• Heating / cooling.• Natural fertilizer without artificial additives.

In an average community, a 1 MW biogas plant can deal with a variety of substrates such as liquid and solid manure, abattoir waste, sludge from wastewater treatment plants and green and organic waste from nearby municipalities. A Nijhuis biogas plant should produce electricity for at least 8,000 hours per year and is capable of using about 100 t of organic waste every day. On an annual basis it produces about 8.000 MWh of electricity and a similar amount of energy (hot water from CHP cooling system and heat recovered from the exhaust gas). This amount of energy can be enough to supply electricity for around 50 households (assuming 20 kW for a single household).

Part of the produced heat is reintroduced to the biogas process itself (digester heating, waste sanitation), however, the remaining heat and/or energy can be used for a variety of other purposes such as heating or chilling, steam, hot water (approx. 900°C) or diathermic oil. The remaining digestate as a result of the anaerobic digestion process is fed to a separation unit. Solids can be dried by using heat from CHP and dried material can be pelletized and sold for burning or used as dry fertilizer. Liquid fraction is stored in storage tanks and used in agriculture as a high quality natural fertilizer.

Alternatively it can be treated in a biological wastewater treatment plant and discharged or used in agriculture for irrigation purposes. There are additional benefits that a biogas plant can offer to local communities. It can be a local, independent, green, renewable heat and power source but it also improves living conditions for local inhabitants. Pig or chicken manure for example is converted into odorless digestate which has virtually no smell as opposed to raw manure spread out onto the fields.

Finally, the energy produced in a biogas plant significantly lowers CO2 emissions. A 1 MW biogas plant could reduce the CO2 emission by approx. 6,500 tons

every year which has a very positive effect on the environment. To put this into perspective, 1ha of pine forest is able to absorb around 30 tons of CO2 per year, so in this case a 1 MW biogas plant is equal to approximately 217 ha of pine forest. It also significantly reduces odor emissions from used waste – H2S is biologically reduced during the process.

The Nijhuis biogas plant also could be expanded with other waste to value systems available at Nijhuis such as ammonium recovery into ammonium sulphate (NAR) or recycling of polished water from digestate. On the one hand this results in a reduction in discharge costs and on the other hand it creates value out of waste and wastewater.

Examples of existing waste to value projects

Nijhuis Industries Central Europe (NICE) has executed several waste to value projects in the food and agricultural market. They differ in size, the type of waste treated and the use of digestate but all have in common that the provided solutions are designed according to the customer’s expectations and possibilities. Both biogas bag-type and Taurus systems have been delivered.

The biogas is used to produce heat or burned in cogeneration engines that generate electrical and thermal energy. One example is the plant delivered by NICE for CEDROB, a leading Polish meat production company and one of the largest food companies in Europe. The biogas plant is an integral part of the complete wastewater treatment system designed and delivered by Nijhuis. NICE has recently signed the order for a complete extension of the existing system involving the wastewater treatment plant to be extended to capacity of 6,000 m3/d and more than double the capacity of the waste to value system.

Biological excess sludge from the wastewater treatment plant, sludge from DAF treatment, as well as sludge from off-site facilities are pre-treated and digested in the Nijhuis Taurus reactors. The digested sludge is dewatered to be used as fertilizer while the biogas is used in the gas boiler producing heat for the purpose of the plant and factory. The liquid phase of the digestate is recycled back to the plant and treated together with remaining wastewater streams. The produced

effluent meets strict environmental requirements and is discharged to the river. Another example is the biogas plant at Grolder farm, located in the Netherlands. This biogas plant is planned to run on pig manure and produced in digesters made of special PVC foil tanks. The purpose of this plant is to utilize all of the manure to achieve the following objectives:

• Reduction of liquid spread on fields.• Little to no unwanted odors compared to raw manure.• Production of green heat and electricity.
