➤➤➤ Wastewater Screening

Screens for any application

Coarse Screen

Fine Screen

Perforated Plate Screen

Mesh Screen

Screening is indispensable as the first stepof municipal and industrial waste watertreatment. Debris must be removed in order to protectsubsequent treatment pro cesses fromclogging and/or damage. Floating, settlingand suspended solids are retained, depend-ing on the bar spacing or perforation dia-meter, removed and finally discharged. Based on the same ROTAMAT® principle“screening – washing – conveying –dewatering in a single unit” a family ofROTAMAT® screens has been developed andsuccessfully introduced in the global marketof wastewater treatment. In recent yearsthe STEP SCREEN® and the MAX® familieshave been added. We offer the perfectHUBER screen for:➤ any installation condition➤ any flow rate➤ any spacing or perforation size

Ultra-fine screens for new applicationsOur development of extremely fine screensfor the separation of very fine particlespermits new wastewater treatment applica-tions for screens. Reliable separation of hair and fibrousmaterial is necessary for efficient perform-ance of membrane bioreactors.

Another application for ultra-fine screens isriver and sea outfalls. Frequently, rawwastewater is only treated mechanicallyprior to being discharged to rivers or seas.Reduction of the COD/BOD loads from suchoutfalls is required for the protection of thereceiving water bodies if their self-cleaningcapacity is insufficient.These ultra-fine screens are able to removeundegradable and degradable, inorganicand organic material at the same time.Improved environmental protection isachieved by application of this new tech-nology at reasonable costs. Chemical coagulation can temporarily beadded to maintain the screening efficiencyand high effluent quality even during peakloads. For many regions with insufficientwastewater treatment, if any at all, ultra-fine screening is a quick and affordable firststep in the right direction.

➤➤➤ Screenings Treatment

Unwashed screenings

Washed screenings

The first step in wastewater treatment isnormally the removal of solids from thewastewater flow by means of screens. The removed screenings contain householdwaste, faecal matter, toilet paper andmineral solids. The screenings volumedepends, not only on the separation size ofthe screen, but also on the type of sewersystem. The solids content of municipal screeningsvaries between 18 % and 25 %, dependingon the type of screen. Approximately 90 %of the solids are volatile (organic). Due to their very high water content, theirheterogenous composition and unaestheticappearance screenings must be treatedbefore they can be disposed of. The best method of screenings treat ment iswashing and compaction with a wash press.Fecal matter and other organic materialsare removed and returned into the waste-water flow.As a result, a good wash press in creases theBOD5 load to the biological treatment pro-cess by about 6 %. After washing, the screenings are com -pacted to reduce the water content andincrease the solids concentration. Dewatering is improved by the removal oforganic materials during washing. A goodwashpress can achieve a weight andvolume reduction of up to 80 %.

A wash press reduces the mass and volumeof the screenings and con sequently thedisposal costs.

➤➤➤ Grit Separation

For reasons of operating reliability of waste-water treatment plants it is necessary toseparate the grit trans ported with thewastewater and other mineral materialsfrom the digestable organic material.Separation of grit, gravel and other mineralmatter is required to increase the reliabilityof wastewater treatment plant operation.Good grit separation prevents operationalproblems, such as grit sedimentation inaeration tanks and digestors, reduces wearof equip ment, such as pumps or sludgedewa tering centrifuges, and avoids cloggingof sludge hoppers and sludge lines.While as much as possible of the mineralmatter should be removed, as much organicmatter as possible should remain in thewastewater. Testing of the grit capture rateis usually done with a grit particle size of 0.2mm. In combined sewer systems, approxi mately60 l of grit can be removed from 1000 m3 ofwastewater. The most common grit separating systemsin use are grit channels, circular grit trapsand vortex grit traps. Grit is either separated by gravity sedimen-tation (grit channels) or centrifugal force(circular and vortex grit traps). Scrapers orscrew con veyors are frequently used in gritchannels for grit collection. Pumps, inclinedscrew conveyors or integrated grit classify-ing screws are used for grit removal. Grit channels are normally provided withaeration to prevent sedimentation ofvolatile solids and reduce the organiccontent in the grit. In addition, aerationhelps to float part of the fat, oil and grease.According to Kalbskopf, detention time is animportant factor in the design of aerated

grit channels. However, even the bestaerated grit channel cannot prevent highorganic contents in the removed grit slurry.Only a good grit washer can guaranteealmost complete separation of organicmaterial from grit and produce clean grit.

➤➤➤ Grit Treatment

Grit from grit traps of wastewater treatmentplants and grit from sewer and road clean-ing are heavily contaminated with organicmatter and debris. The high content oforganic material, the wide volatile solidsratio of 10 to 80 %, is the reason why suchgrit slurries do not dewater well. The solidsconcen tration remains somewhere between.The common performance criteria for thequality of grit removal are: The capture rateof 0.2 mm diameter grit particles; and thevolatile solids concentration of the removedgrit. The end product of excellent grittreatment is a reusable product with avolatile solids ratio of less than 3 % and awater content of below 10 %. Such grittreatment not only reduces the volume andmass of the removed grit, but also thedisposal costs. If the clean grit product isreused, e.g. for road bedding, costs for gritdisposal could be avoided.

Treatment of grit from wastewater For the treatment of grit from grit traps onwastewater treatment plants, HUBER gritwashers have proven to be the unrivalledbest option. HUBER grit washers achieve anoutstanding grit product con taining lessthan 10 % water and below 3 % volatilesolids. It is so clean that beneficial use iseasily possible. Equally important is thatHUBER grit washers have a 0.2 mm gritparticle capture rate of about 95 %. Over a thousand HUBER grit washers aresuccessfully operating worldwide.Regulations requiring certain grit qualitycriteria, depending on the kind of itsdisposal and/or reuse, are coming into effectin more and more countries. So far, HUBERgrit washers have easily met all suchrequirements and will most likely do so inthe future, because they have defined theindustry stan dards.


25

Treatment of grit from sewer flushingand road refuse The characteristics of grit from sewerflushing and from gully and road cleaningcan vary widely. Their treat ment must becustomized, depending on required capac-ity, input material composition, outputmaterial quality, etc. Main process stepsare: storage and balancing, debris sepa-ration, grit classifying and grit washing.Where there is no wash water supply avail -able, wash water treatment and re circula-tion is an option. Based on their wide ranging experience andexpertise, HUBER Engineers will design yourcustomized grit treatment system for yourspecific needs.

➤➤➤ Sewer System Managementand Storm Water Treatment

An important part of our efforts to protectthe environment in general, and our waterresources in particular, is treatment ofstorm water and of overflows from com-bined sewer systems. The quality of manyrivers, lakes and seas has significantlyimproved following the upgrading of old andconstruction of new waste water treatmentplants. However, despite all these effortsand invest ment, there is still considerablepollu tion of our water bodies caused bycombined and sanitary sewer over flows(CSOs and SSOs) during storm events. For the purpose of specific environmentalprotection appropriate measures will haveto be taken in future to minimize theseproblems.

Screens for sewer overflowsHUBER screens are used to retain debrisand other coarse solids within the sewersystems and to prevent them fromoverflowing into receiving water bodiesduring storm events. We have a variety ofscreens suitable for application at seweroverflows. For such applications bar screensand perforated plate screens can beselected. We offer screens that are installedupstream of, on top, or down stream ofoverflow weirs. The optimal ly suited screenis selected depending on the required ordesired capture rate, flow requirement andstructural conditions. Our global presenceand experience allows our experts to pro -pose the best solution to any problem.

Flushing of storm water tanks Due to the limited storage capacity ofsewers, additional storage facilities areinstalled at exposed positions, such asstormwater overflow, retention orclarification tanks, which retain the firstflush of stormwater and discharge it to thewastewater treatment plant after the stormevent.Suitable cleaning systems are required for sewers and storm water reten tion tanksand clarifiers to maintain their function and performance and to prevent odournuisance, toxicity and safety hazardsresulting from anaerobic digestion ofdeposits and generation of sewer gases. The most effective, most reliable and leastexpensive method of cleaning sewers andstorm water basins is surge flushing.HUBER Tipping Buckets SK have been wellproven for the flushing of all types anddimensions of tanks.

Equipment and systems for combined and separate sewer systems

Flushing of sewers We offer an innovative and proprietarysewer flushing system with flaps. Oursystem offers the benefit of achievinglasting cleaning results of even long sewersdue to powerful and long flushes. Thisavoids costs for mobile sewer cleaning. Alsothe dry weather flow can be used for regularsewer flushing to prevent sedimentation inaffected sewer sections. The system issuitable for any sewer cross-section andnormally also for retro fitting withoutinterruption of sewer operation.Storm water retention in sewer systemsAnother HUBER focus are intelligent andefficient systems for controlled storm waterretention in sewer systems. In order to saveinvestment and operating costs, it isessential to utilize the existing sewervolumes more effectively for storm waterretention by controlling the water levelswithin the system. In many cases, with suchan intelligent approach, construction ofadditional retention tanks can be avoided.Pollution by unavoidable storm water

overflows can be minimized by installationof storm screens. Discharged flow volume measurementMonitoring the utilisation of storm waterretention tanks and of overflows becomesever more important to allow optimising theuse of retention volumes and minimizingoverflow occurance and flows. It is essentialto be able to measure discharged stormwater flows and volumes. In the past thishas not been possible where a storm screenwas installed. This is now possible with ourequipment.

➤➤➤ Heating and Cooling with Wastewater

Energy recovery from wastewaterRight below the ground, in sewers, is ahidden and seldom used source of energy:our wastewater. Generally the temperatureof sewage is in the range of 12 to 20 °C.Even during winter the wastewatertemperature never drops below 10 °C, oronly for a few days. This makes wastewateran excellent heat source for the operation ofheat pumps.

Utilisation of wastewater as a heat source isespecially suitable to be applied in largebuildings, such as nursing homes, hospitals,schools or swimming baths. It is alsopossible to recover heat from the effluent ofsewage treatment plants and use it e.g. forsludge drying.

As a link between the wastewater and heatpump, a heat exchanger is required to ex-tract the heat energy contained within thewastewater. The heat exchanger transfersthe thermal energy from the wastewater tothe heat pump. The innovative HUBERThermWin® system which has beendeveloped especially for such applicationsuses the HUBER RoWin Heat Exchanger. The specific feature of this system is thatactual heat extraction from the wastewatertakes place above ground and not in thesewer. All system components are easilyaccessible and easy to maintain. For theexchange of heat directly in the sewer wehave developed the HUBER TubeWin HeatExchanger so that we can offer a suitableheat exchanger for any application.

Functional principle of the HUBER ThermWin®:A partial flow of the wastewater streamingthrough the sewer is passed through ascreen to remove the coarse material fromthe wastewater flow. Preceding screening ofthe wastewater is necessary to preventblocking of the heat exchanger. The pre-screened wastewater is lifted and flows bygravity through the above ground installedheat exchanger, the cooled wastewaterflows back to the sewer taking along theseparated screenings. Heating of thesecondary circuit, which is coupled with the heat pump, takes place inside the heatexchanger. The heat pump lifts the tem-perature to the requested level. For applications with contaminated mediathe HUBER Heat Exchanger RoWin can beused. This type of heat exchanger has beendeveloped especially for such applicationsand excels with its superior heat transfercapacity and automatic preventive cleaningof the heat exchanger surfaces. Up to 80 %of the useful heat can be recovered from thewastewater and utilized economically.

➤➤➤ Sludge Treatment

Sewage sludge is continuously generatedon municipal and industrial wastewatertreatment plants during the process oforganic pollutant degradation. In the pastyears, the annual volume of municipalsewage exceeded 10 million tons drysubstance in Europe alone, and the trendcontinues upward. Due to the very differentrates of connection in the individualcountries, with e.g. a rate of virtually 100 %in the EU member states, and thereforeregionally very different sewage sludgevolumes it is only understandable that thereare controversial approaches as regardssludge disposal ways.

In some countries, due to new legislationand eco-political consideration, somedisposal methods have been prohibited orat least restricted, such as landfilling ofsewage sludge. For many states therecovery of materials contained withinsewage sludge still plays an important role.This applies to both landscaping and sludgespreading on agricultural land.

The fertilization effect of sewage sludge and especially its phosphorus content isnormally sufficient to cover the nutrientsdemand of typical agricultural land. On the other hand, there are a lot of countrieswhere the agricultural application of sewagesludge is met with much scepticism due toits potential heavy metal pollution andcontent of organic pollutants, such as PFT. In these countries there has been a cleartrend towards concepts for thermal sewagesludge treatment for some years already,partly combined with the approach torecover the phosphorus contained withinsewage sludge. Against this political and

economic background it is understandablethat the sewage sludge disposal issue canbe discussed quite controversially. Even ifthere is no generally accepted concept forfuture sewage sludge disposal existingpresently, adequate sludge pre-treatment isrequired with all concepts described above.

A major pre-treatment step is to reduce thewater content of the sludge. Sewage sludgegenerated on wastewater treatment plantstypically shows a DS between 1 and 5%depending on where exactly it is generated.The average DS content of digested sludgeis 45 %. This means that one cubic metre ofdigested sewage sludge contains 950 l,which would permanently have to betransported without prior dewatering. The major benefits of dewatering and dryingare weight and volume reduction and theincreased thermal value.

Consequently, the process chain that allowsfor later thermal utilisation of dried sewagesludge comprises the steps of prior screen-ing, thickening and drying.

➤➤➤ Mechanical Sludge Treatment

Mechanical sludge treatment primarilycomprises the processes of sludgescreening, thickening and dewatering.

Sludge screeningSludge screening is a mechanical treatmentstage that primarily achieves homogenisa-tion and separation of foreign matter andensures therefore undisturbed furthertreatment of the sludge, irrespective of thesubsequent treatment methods applied.Operating problems, such as clogging ofpipelines, pumps, heat exchangers ordownstream filtration units, tressing onstirrers and aeration plants, scum in settlingand sludge tanks as well as damage indownstream drying units, can reliably beprevented by using HUBER sludge screens.

The STRAINPRESS® is a horizontal, pipe-shaped coarse material separator. Thecoarse material is separated continuouslyunder pressure and periodical cleaning ofthe screening zone by backwashing isthereby not required.

Sludge thickeningWith regard to economical further treatmentand disposal of sewage sludge, it isnecessary to reduce the sludge volumesproduced in the course of the wastewatertreatment process. The volume reduction isachieved by separation of parts of thesludge liquor at different points in thesludge treatment process chain. The mainfield of application of thickening systems isvolume reduction of primary and excesssludge prior to stabilisation. In addition tocommon sludge thickening systems, e.g.belt and drum thickeners, HUBER offers also

its optimized own developments, such asscrew and disc thickeners. The selection ofthe most suitable technology for individualapplications depends on project-specificparameters, such as throughput capacity oroperating and investment costs, but also onother criteria, such as operating reliability,flexibility and process complexity.

Sludge dewateringSludge produced in municipal and industrialwastewater treatment plants requiresdewatering prior to further treatment orutilisation. In view of increasing sludgedisposal costs it has become necessary toconcentrate the sludge to a high solidscontent. HUBER offers for this purposecommonly known systems for continuoussludge dewatering, e.g. belt filter presses,but has also developed a machine forsmaller and medium-sized wastewatertreatment plants, the ROTAMAT® ScrewPress. It is this wide range of productscombined with many years of experiencethat enables HUBER to select the bestsuited technology for each individualapplication.

➤➤➤ Thermal Sewage Sludge Drying and Utilisation

Sewage sludge disposal is becoming anincreasing problem, landfilling was pro-hibited in 2005. Spreading sludge onagricultural land is in dispute and also itsuse for landscaping is no long-term solution. As all these methods cannot guarantee thereliable removal of contaminants from thematerial cycle, thermal utilisation remainsas best possible alternative.

Sewage sludge consists of more than 95%water that requires transport, disposal orfurther processing. If the water content isreduced to 10% or less, costs can be re-duced significantly. But a lot of energy isrequired for drying. The energy demand ofavailable drying systems varies, as well astheir operation and end product quality.Which system is suitable for the individualsewage treatment plant needs to be clari-fied for each specific case. HUBER has thesuitable drying method with optimal usageof energy for any application.

Solar sewage sludge drying

The basic principle is sewage sludge dryinginside a greenhouse. This solution allows forcontinuous system operation so that thesludge bed in the greenhouse remainsconstant. Due to the special features of thesludge turning assembly, particularly thebackmixing function, an open-pored andslightly wet sludge bed is generated thatcauses neither odour problems nor un-necessary dust loading.

The sludge is fed manually, with a wheelloader for example, or automatically bymeans of special conveying units, directly

from the dewatering system. The driedsludge can be stored in a ground deposit atthe end of the drying hall or mechanicallytransported directly to a loading station.

The sludge turner is the heart of the HUBERSRT drying system. It consists of a rotatingdouble shovel which is used for two differentmotion sequences. The sludge turningfunction ensures mixing, breaking up,aeration and transport of the sludge. Thesecond function is the transport of sludge in the turner shovel, i.e. the sludge turnertakes up some sludge at a defined point and transports it inside its shovel to anotherpoint. This ensures that dry sludge is back-mixed into wet sludge and sludge feedingand removal can take place at the samegable side of the hall.

The HUBER SRT system is not only suitablefor pure solar drying but also ideal to becombined with a high performance floorheating or hot air blower. Optimized withsuch a heating, the SRT system can be usedfor all year round, season-independent solarsewage sludge drying. This eliminates theneed for storage facilities for wet sludge andsaves the floor space required for solardrying without additional heating as solardrying alone is unable to dry wet sludgeduring winter.

Belt drying

The excellent product quality and reliabilityof the HUBER belt dryer are the results of aspecial sludge pelletising technology. TheHUBER Belt Dryer BT operates as a two-beltdryer at medium temperatures. The dryer isable to produce a dust-free granulate with adry substance in excess of 90 %. Optimalusage of energy and combination ofdifferent energy sources ensures aneconomical dryer operation. This is anexperience HUBER has made for more than10 years, since the company started tocommit itself to sludge drying solutions.

Thermal utilisation with sludge2energy

The core part of the sludge2energy systemis decentralised sewage sludge dryingcombined with mono-incineration of sewagesludge. In the pilot project Straubing amedium temperature belt dryer has beencombined with a grate stoker furnace andcompleted with a micro gas turbine toachieve an energy-self sufficient utilisationproces of drying and incineration. EachHUBER sludge2energy system is tailored tomeet specific customer require-ments andsite conditions. This guarantees optimumeconomic efficiency and maximumreliability of operation.

➤➤➤ Sedimentation / Secondary Clarification

Clarified Water Discharge from Secondary Clarifiers

Secondary clarifiers are in most cases thelast treatment stage of the activated sludgeprocess and therefore contribute significant-ly to the overall performance of a waste-water treatment plant. The efficiency of thesecondary clarifier as last treatment stage isdecisive for whether the quality of thewastewater treatment plant effluent meetsthe standards of the Waste Water Levy Act.Secondary clarifiers should thereforeremove as much as possible of thebiological sludge, activated sludge ortrickling filter sludge, from thewastewater. The peak flow during stormevents is critical for the design of theclarifiers. If the sludge layer rises too highthere is a risk of sludge overflow ing with theeffluent. Sludge overflow ing must beprevented in any case to comply with theconsent standards. A further determining factor for clarifierperformance is a uniform and slow outflowof the effluent from the clarifier which canbe guaranteed with a HUBER SubmergedEffluent Pipe. Uniform and slow overflow over a weir intoan effluent channel could only be achieved,if the rim of the weir would be and remainabsolutely level and if the water level wouldnot be affected by wind.

If one of these requirements is not met theperformance of the clarifier is not optimal.In extreme cases, the entire overflow occurson one side of the clarifier, with highvelocity, and no water overflows on theopposite side. If this happens, the flowpattern in a circular clarifier will be so badlyimpaired that only approx. 50 % of the tank is used, this results in hydraulicoverload, in a poor clarifier performance,and sludge overflow.All these problems can be eliminatedcompletely with the use of a HUBERSubmerged Effluent Pipe. The HUBERSubmerged Effluent Pipe ensures theconstant submersion height over the pipeopenings of 30 cm so that the pipe remainsunaffected by external influences. An outletflow control system ensures that thesubmerged effluent pipe is adaptable toeven strongly varying inflow situations.

➤➤➤ Filtration / Deep Bed Filtration

Sand filtrationDue to increased requirements on theeffluent quality of wastewater treatmentplants – both for direct and indirectdischarge – the operators of municipal andindustrial plants are forced to implementadditional treatment steps to ensure therequired effluent standards are met.Sandfilters are a cost-effective solution tomeeting effluent standards in variousapplications.The CONTIFLOW® Sand Filter is an upflowfilter with a continuously cleaned filter bed,making shut downs for cleaning or back-washing of the filter bed un necessary. The feed is introduced at the top of the filterand flows down ward through an openingbetween the feed pipe and airlift housing.The feed is intro duced into the bed througha series of feed radials which are open atthe bottom. As the influent flows upwardthrough the moving sand bed, the solids areretained in the filter sand. The filtrate exitsat the top of the filter and flows over a weir.Simultaneously, the sand bed, along withthe accumulated solids, moves downwardand is drawn into the lower end of the airliftpipe which is located in the center of thefilter. The sand is lifted to the upper end ofthe airlift pipe where it falls through awasher which consists of several concentricstages.

A small amount of filtered water passesupward through the washer, washing awaysludge from the sand, while allowing thecleaned sand to fall through to the washer.By setting the reject weir at a lower levelthan the filtrate weir, a steady stream ofwash water is assured. The continu ousreject exits near the top of the filter so thatit can run off by gravity. The typically used filter bed height formunicipal applications is 1 m (2 m forphosphorus removal / denitrification).Depending on the plant size, the filter tankis made of steel or concrete.

Typical Sandfilter applications:

➤ Tertiary filtration after secondaryclarifiers

➤ Phosphorus elimination throughprecipitation and filtration

➤ Algae removal ➤ Partial removal of nutrients➤ Process water conditioning, e.g.

reverse osmosis pre-stage, or cooling water conditioning

➤ Industrial wastewater treatment

➤➤➤ Membrane Technology / MBR /Wastewater Reuse

Membrane bioreactors for any throughput

Inexpensive wastewater disinfectionWastewater treatment in municipal andindustrial plants can require large areas, bigtanks, expensive odour control equipment.Where freight and loads vary widely, theperformance of the treatment processes isoften poor.

All these factors result in heavy impacts inthe form of contamination of our environ-ment, very limited possibilities of waterreuse, and also high construction, operationand maintenance costs. Membrane Bio-Reactors (MBR) need by upto 70 % less volume which results in con-struction cost savings. MBRs have an im-

proved performance. Clarifiers are elimi-nated and therefore the problems that scumor sludge could overflow from a clarifier.Existing structures can be retrofitted andtheir performance increased. Existingprimary and secondary clarifiers can bemodified and used for example for storageor redundancy.The effluent of MBR systems complies withall current standards. The effluent does notcontain bacteria and other germs. It can beused as service water or for irrigation. Evena MBR permeate of drinking water qualitycan be achieved by adding further treat-ment stages.

For over a decade HUBER has been heavilyinvolved in membrane technology formunicipal and industrial waste-watertreatment. In the meantime we havecontinuously improved the design of ouroriginal VRM® units (Vacuum RotationMembranes), we have optimized theirperformance and adapted manufacturing to the increasing demand in the market.VRM® units simultaneously excel with theirhigh capacity of in excess of 100 m³/h, lowpower consumption and long life.

A special feature of these membrane unitsis their rotation that allows sequential buthigh-intensity air scouring of theirmembrane surface.

The specific scouring air flow is as low as150 - 250 l/(m²∙h) because the scouring airis supplied by air tubes to the VRM’s centralaxis. Furthermore, the air can be blown in atonly half the depth required otherwise. Weachieve improved scouring of the membranesurface, with comparatively low powerconsumption and infrequent chemicalcleaning. For decentralized applications weuse our HUBER BioMem® plants that includestationary membrane plates.

Both systems are available as completesolutions or optionally as components forintegration into the customers’ plants.

We provide all our membrane units with top-quality ultra-filtration membranes andtherefore combine best effluent quality withlow cleaning and maintenance costs andlong life. Compared to hollow fibremembranes membrane plates have theadvantage that no plaiting can occur and a3 mm perforated screen is sufficient aswastewater pre-treatment system.

It is our philosophy to offer high-qualitymembrane units with long life and bestvalue.

In contrast to our competitors we preferplate membranes due to improvedoperational reliability, ease of maintenanceand chemical cleaning, and we offeroutstanding global after- sales service.

We have the philosophy that a high degreeof vertical manufacturing integration is inthe best interests of our customers. To prevent any cross-contamination of ourstainless steel products with carbon steelrust and dust, we use only stainless steel inour factory. Our machinery and manufactur-ing processes are specifically designed forthe material stainless steel. Every stainlesssteel product, before it leaves our factory, ispassivated by full sub mergence in an acid(pickling) bath for perfect surface finishingand corrosion protection.

Potable water is a most important re sourcethat should be available for all people insufficient quantity and quali ty. We offer thehighest quality pro ducts for the treatment ofdrinking water.Drinking water must be pure, i.e. clear andfree of pathogens, odour and colour. Tocomply with these require ments certainstandards have to be met during collection,treatment and distribution of the drinkingwater. Many waterworks, however, do not meetthese standards and are a danger to ourhealth and environment. It is important toidentify such risks as early as possible toprevent further damage.We have developed systems for water-works that prevent contamination ofdrinking water, such as special air filteringsystems.
