Drawing on more than three decades of experience

in woven media filtration technology, the Forty-X™

disc filter provides a simple and highly reliable

filtration system.

At the heart of each Forty-X™ disc filter, individual

media panels—with integral frames—support the

woven media and ensure the geometry of the

pleated surface. The media panels are a molded one

piece construction with structural stiffeners through the

center of the panel area. This unique pleated design

reduces the opportunity for fabric tear-out and effluent

contamination. The pleated media design increases the

true cloth area available for filtration by 40% over flat

panel designs. This assures a more sustainable operation

in terms of throughput, better feed distribution, and

fewer backwash cycles.

The Forty-X™ disc filter uses pleated, woven media in a unique inside-outconfiguration, which provides maximum disc filter performance, whileeasily rejecting troublesome inorganic material.

The pleated surface of the Forty-X™

disc filter panels dramatically

multiplies the filtration surface

area.

The inside-out flow of the Forty-X™ disc

filter panels effectively captures suspended

solids and adds to backwashing efficiency.

Each circular disc assembly is made up of 28 media

panels. The media panels are mounted on the central

influent drum to form the individual circular discs. The

number of circular disc assemblies mounted on the

central influent drum range from 1 to 24, depending

on the scale of the installation.

In operation, influent flows through openings in the

central drum, into the center of each media panel and

then flows out through the filter media as high quality

filtrate. This provides an inside-out flow, which

captures solids on the inside of the filter panel and

makes these solids far easier to remove during

backwashing cycles.

The inside-out filtration flow, combined with the

dynamics of the central influent drum adds further

to the simplicity of the Forty-X™ disc filter by

eliminating the need for a separate system for

handling floating and sinking material. The Forty-X™

disc filter effectively isolates trash so it is easily and

quickly transferred to the reject flow.

The Forty-X™ disc filter configuration minimizes

lifetime costs with fewer moving parts and lower

energy demands for backwashing. Wind-safe sliding

covers provide easy access to the interior, making

inspection of the media panels, quick release spray

nozzles and the centralized lubrication block simple.

With the Forty-X™ disc filter, the filtrate is always

accessible and in plain view.

The Forty-X™ disc filter frame-only design is an ideal

drop-in retrofit for existing traveling bridge filtersand provides an easy retrofit for most other

conventional filtration systems. This is because of

the exceptionally small footprint relative to the high

volume filtration capacity of the Forty-X™ disc filter.

Also, the micron-rated media panels can be

changed-out when filtration requirements change.

Designed, engineered, and constructed by the

skilled Siemens Water Technologies team, the

Forty-X™ disc filter represents world-class quality in

every respect.

The Forty-X™ disc filter is Title 22 approved.

The modular design of the Forty-X™ disc filter

offers flexibility for a broad range of flows

and applications including: municipal tertiaryfiltration, water reuse and process water

filtration.

High quality, high volume filtration is becoming increasinglyimportant to all industry professionals. Quality tertiary filtration is

now necessary to meet many effluent requirements and the need for

water reuse is well documented for most areas. In addition, the

advantages of industrial process water filtration have become more

widely recognized.

For decades, deep-bed sand filtration was one of the few effective

options, however this method had the distinct disadvantage of

requiring a large area of physical space. Today, there are a number of

other filtration options, many of which pack a tremendous amount of

filtration capacity into an extremely small physical space. Among the

most practical and efficient are disc-type filtration units.

Typically, disc-type filtration units employ rotating, unitized screened-

panels as the filtration media. Each specific manufacturer of these

now popular disc-type filtration units is unique relative to the form of

filtration media used and in the engineering of their individual units.

Some disc filters depend on a pile-type media for filtration, which has

the disadvantage of highly variable filtration capabilities owing to therandom variability of the pile media.

Disc filter units that incorporate woven-type media provide the most

consistent effluent for most filtration applications as the result of

their absolute cloth media rating.

Among disc filter units using woven-type media there are two

options, flat media and pleated media. The obvious advantage of

pleated media is that it increases the true cloth area available forfiltration by 40% over flat panel designs. Plus, pleated media is

structurally more durable and can easily withstand much higher

headloss conditions than other media configurations.

For these reasons, the Forty-X™ disc filter is engineered around

pleated, woven-type media, which allows high volume, high quality

absolute filtration as well as long term, trouble-free operation.

An absolute media rating is providedwith woven media. (10-micronopenings shown.)

Rating is nearly impossible with pilemedia.

The pleated surface increases thetrue cloth area available for filtrationby 40% over flat panel designs.

EC Goals

To effectively protect rivers, lakes,

coastal waters and ultimately the

public health, municipal waste water

must be disinfected before release to

the environment. Biological

treatment, even when combined

with clarification and filtration, does

not provide adequate removal or

inactivation of dangerous bacteria

and viruses. Where waste water

can enter bathing or drinking water

resources, the risk of human infec-

tion makes disinfection prior to

discharge an absolute necessity.

Waste water reuse for irrigation

and other purposes is increasingly

required to meet the needs of rapidly

expanding population sizes,

especially in arid climates. Provided

there is a disinfection system in place

to safeguard water quality, reuse

represents a positive, safe method of

water conservation that is set toincrease dramatically in the future.

Natural disinfectionwithout chemicals

Ultraviolet technology provides a

proven, accepted and

environmentally friendly method of

disinfecting waste water. Whenexposed to UV-C light,

microorganisms are inactivated

within seconds through a physical

reaction with the organisms’ DNA.

In contrast to chemical disinfection,

UV produces no harmful by-

products. It also eliminates the risk 

for opera- tors associated with

handling dangerous chemicals. Two

major advantages of UV disinfection

versus chemical methods are

increased disinfection effectiveness

(especially against viruses) as well as

space-savings due to shorter reaction

times. Since no chemicals are

introduced into the water, no ”post-

treatment” is required to remove

these chemicals before discharge to

the environment.

Effective and economicultraviolet systems

WEDECO has more than 20 years

of experience in the development

and application of UV technology.

The TAK series was specificallyengineered for the disinfection of

municipal waste water. Several

different TAK design configurations

are available to meet worldwide

regulatory requirements (e.g.

European bathing water guidelines,

WHO guidelines for irrigation,

California’s Title 22 for waste water

reclamation, etc.) and cope with

varying degrees of water quality

depending on the level of pretreat-ment (e.g. primary, secondary or

tertiary). Installed in final effluent

channels, the modular design of the

TAK allows for practically unlimited

flow capacities.

WEDECO

Throughout the world, WEDECO TAK 

systems demonstrate their

effectiveness and reliability every day

of the year.

The design of any UV system starts

with the selection of the right lamp

technology. The lamp in turn is only

as good as the ballast that powers it.

This lamp/ballast combination and

the available control philosophy willdetermine the performance,

operating costs and reliability of the

UV system. Since UV light can only

disinfect properly when it can enter

the medium unhinderedly, the

overall performance of a UV system

is also dependent on the

effectiveness and reliability of its

automatic cleaning (i.e. wiping)

system. TAK series disinfection

systems utilize the most advanced

technology available in all four of

these critical areas.

Like Spektrotherm® lamps, medium

pressure mercury lamps (”multi-

wavelength” lamps) also emit a very

high UV output. However, a signi-

ficant portion of their energy

output consists of wavelengths

outside

the effective disinfection region of

the electromagnetic spectrum. This

non-productive energy leads to

higher electrical operating costs and

installation of a larger electrical

service to the system.

WEDECO Spektrotherm® lamps and

ballasts also feature variable output

control to precisely match changes

in flow rate and/or water quality.

This technology truly provides

”The Best of Both Worlds”.

WEDECO continues to set the pace

in UV technology development. No

other company can match

WEDECO’s 15 plus years of ”Low

experience.

This results in:

• Fewer lamps required

• Reduced design/construction

Chemical-free WipingSystem

One of the most important features

in state-of-the-art UV systems for

waste water is automatic cleaning to

keep the equipment performing well

day-in and day-out. The TAK series’

automatic wiping system performs

this function like no other.

Employing specially designed wiper

rings, it prevents organic and

inorganic deposits from

accumulating on the lamp protective

quartz sleeves. This ensures that the

UV light actually reaches the water.

The TAK series’ wiping systems are

designed to operate continuously

without disrupting the disinfection

process. Wiping frequency and

”wipes per cycle” are fully fieldadjustable to match specific waste

water characteristics. Even when

lamp banks are in ”stand-by” mode,

their quartz sleeves are automatically

kept clean and ready for operation.

The smooth, reliable operation of the

TAK wiping system is due largely to

its use of a high performance

pneumatic drive and ”torsion-free”

floating wiper array.

Smart Ballast Operation

TAK systems employ WEDECO’s

advanced variable output electronic

ballast, developed specifically to

operate Spektrotherm® lamps. It

offers a multitude of unique features

for maximum system performance

and reliability.

These include:

• Very low power losses for

increased efficiency

• Infinite adjustment of UV lamp

output

• ”Smart” automatic lamp

restart on ignition failure

• High output stability for long

lamp life

• Lamp failure detection

• Very high power factor

(>0.98)

• Ease of maintenance

The result is perfectly clean quartz

sleeves, completely without

chemicals.

The degree of micro-organism

inactivation in a UV system is a

function of the UV dose received

by the organisms:

UV dose = UV intensity x Retention

Reliable and intelligentdisinfection control

The UV intensity to which an

organism is exposed is dependent on

the lamp output, quartz sleeve

cleanliness and effluent UV

transmittance. By using dedicated UV

intensity sensors mounted within thelamp arrays, each of these variables

is automa-tically incorporated into

the measured intensity value.

Exposure time is derived from the

ratio of the UV system ”reactor”

volume to the effluent flow rate. The

resulting UV dose can be calculated

by the control system as a product of

the measured UV intensity and

exposure time.

Additional TAKAdvantages

True dose pacing

The TAK series is unique in its

ability to provide true ”dose-paced”

system control. This intensity-based

control technology actively monitors

and controls the UV dose delivered

to micro-organisms by measuring

the ultraviolet intensity within the

UV system itself. The system adjusts

lamp power automatically (up or

down) to compensate for intensityfluctuations caused by changes in

water quality, lamp ageing or quartz

sleeve cleanliness.

Control systems that utilize a flow

signal alone (”flow pacing”) or in

combination with water trans-

mittance cannot provide accurate

”dose-pacing” due to their

ignorance of critical variables

including actual quartz sleeve

transmittance and UV lamp output.

The TAK systems are able to employ

true ”dose-pacing” as a result of

their exclusive use of accurate,

Ease of maintenance

In the development of WEDECO

products, special attention is

always devoted to maintenance

considerations. The successful

operation of any UV system is

dependent upon the frequency

as well as the ease of maintenance.

In TAK systems WEDECO has

succeeded in minimizing main-

tenance requirements through the

use of advanced technology, quality

engineering and construction. The

long life of Spektrotherm® lamps,

exceptional ballast reliability,

superior lamp module construction

and an extremely effective wiping

system all serve to minimize the time

and costs to maintain a TAK system.

WEDECO accomplished much of the

timesavings simply by designing the

TAK system to provide easy access to

all system components.
