Clean Conditions –High Benefit

The objectives of waterprotection policies makeconstantly increasing re-quirements on morethorough waste waterpurification. Therefore, a

further increase in the volume ofsewage sludge produced world-wideis anticipated in the future.

Both municipalities and industry areobliged to dispose of the growing quan-tities of sewage sludge in an environ-mentally safe and economical manner.The disposal of sewage sludge must be

secured in the future, employing the lat-est standards of technology to ensure thatvaluable materials are recycled. The optimum and economical dewater-ing of sewage sludge is a central step forall recycling possibilities.

Concentrating on the Essentials

The method of disposal and the associa-ted requirements on the degree of de-watering determine the economy of adewatering unit. Any increase in the con-centration of solids is beneficial in termsof reducing landfill and transport costs.

The Less the Better

To allow the sewage sludge to be recycled or disposed of in line with thecorrespond-ing requirements, optimumdewatering is necessary before drying, -incineration or dumping. The decantersfrom Westfalia Separator fulfil theserequirements by a high g-force(separation efficiency) and optimumtorque control.

A high degree of dewatering guarantees a substantially reduced sludge volumeand thereby significant cost reductionsfor:

• Transport

• Landfill

• Energy consumption during drying or incineration

Optimum Thickening – Reliable Operation

Westfalia Separator | 6 |

VariPond® Ensures aConstant SolidsConcentration

Statutory regulations forphosphorous and nitrogenelimination and changesin the process engineer-ing of waste water treat-ment make the mechani-cal thickening of sewagesludge unavoidable.

For example, the controlled thickeningwith decanters can reduce the volumeof the surplus activated sludge by 90%under normal circumstances. The patented VariPond®-system fromWestfalia Separator ensures constantdry substance values in the dischargeeven when the feed concentrationsfluctuate.

Small Box – Big Impact

VariPond® stands for “Variable PondDepth” in the running machine.In the past, it was necessary to stop andmodify decanters used to thicken sludgein order to achieve a constant dischargeconcentration.

VariPond® now makes it possible tomake the optimum adjustment simplyand reliably when the machine is runn-ing. The machine adapts automatically tothe changing feed conditions. This is anenormous advantage which ensures opti-mum thickening, thereby saving a greatdeal of time and money.

Online Measurement for Reliable Operation

By the use of optical sensors, which ope-rate by the backscatter light principle, thedry substance content of the sludge canbe measured online. This achieves anaccuracy of ± 0.3 % dry substance under

operating conditions, allowing reliableand unsupervised operation during thenight and at weekends. The constantconcentration means that the design ofthe digestion tower can be optimised and it can be operated economically. The sludge digests more efficiently andthe quality is enhanced.

Regardless How Thick and Fast

Regardless how thick and fast, VariPond®

will not desert you. All decanters with athroughput up to 350m3/h can now beequipped with VariPond®. The fields ofapplication extend from the thickening of primary sludge and surplus activatedsludge in waste water treatment plants to the controlled concentration of liquidstreams in the starch and beverageindustries.

Clear Solutions forMany Applications

Waste water technology integrated inproduction processes for resource-min-imised production is a broad spectrumof applications for WestfaliaSeparator.Recycling, making a material useful ina circulatory production system by se-paration, is a task for special decantercentrifuges in diverse industrial appli-cations.

The use of high-alloy stainless steelsfor all components in contact with theproduct ensures a high degree of dura-bility and a long service life.Innovative features such as high g-forces,large clarifying surfaces, optimisedfeed systems, special drives and adegree of dewatering which can beadjusted externally during operationensure optimum clarifying perfor-mance and highly economic operation.

Clear Solutions from “A” to “Z”

The fields of application are as diverse asthe industries themselves. Whether in thefood industry, chemicals and pharmaceu-ticals, the computer industry, energymanagement, the paper industry or agri-culture – separating technology withdecanters and separators provides clear-cut solutions in all fields of application.The fields of application extend from thetreatment of atomic power plant washwater through glass powder recovery tothe purification of waste water fromcellulose production.The smallest particles of slag produced

Drinking Water – A Valuable Resource

It’s Time for Some Treatment

Drinking water is a valuable resource.The average world-wide per capitawater consumption is estimated at 150 cubic metres each year.Only a very small proportion of this isactually consumed.

Drinking water is gained either from theground water or from surface water. Withgrowing populations and increasing lev-els of pollution, the employment of sur-face water is increasing constantly.Surface water is treated by centrifugalseparating technology to remove theundesired constituents.

It Has to be Clean

Heavily polluted surface water is treatedby various chemical processes. Decantersare used to dewater the sludge producedin this process. The proportion of mineralpollutants in the raw water and the typesof chemicals used for precipitation arehighly significant for the dewateringprocess.

Fast and Efficient

Clarifying decanters are employed todewater the sludge in drinking watertreatment plants. These were developedfor high-performance clarification and the highest possible dewatering of thesolids. Amongst other features, this isensured by the high bowl speed and ahigh scroll torque in conjunction with adifferential speed regulation operatingproportionally to the solids loading. Theclosed design of the machines inconjunction with an enclosed installationprevents the escape of aerosols, protect-ing people and the environment.
