Process water and wastewater

Process water

Process water is indispensable for industrial processes and must remain continuously available in the required amounts. Innovative production processes, too, require a consistently high water quality.

High demands on production processes are now increasingly defined by practical requirements. For businesses to meet these requirements, we and our cooperation partners jointly develop optimized methods of treating and recycling of fluids.

Main requirement 1: Absolute filtration

Pore size can be precisely defined according to the customer's wishes, i.e. the filter material's structure determines the medium's absolute separation limit.

Main requirement 2: Constant volumetric flow

The filter system can achieve a constant volumetric flow, i.e. continuous filtration capacity over the entire operating period.

Main requirement 3: Active regeneration

The employed filters can be quickly backwashed and dependably regenerated.

Main requirement 4: Recycling capability

The benefits of items 2 and 3 maximize recycling capability.

Main requirement 5: High filtration yield

The filter system achieves a very high filtration yield, leaving only a small amount of highly concentrated fluid requiring disposal.

Extended service life and significant savings

"Separation of ultra-fine particles in water extends the service life of process fluids by a multiple factor, thus leading to significant savings in terms of the employed chemicals and, especially, disposal of waste liquids. A very positive side effect is the fact that cleaning of the process fluids during ongoing operation notably improves degreasing efficiency and enables reproducible adherence to quality specifications."

Waste water

"The market for conditioning of industrial wastewater has lately received some attention in view of increasingly stringent regulations regarding wastewater discharge. Water recycling and purification of industrial wastewater are becoming attractive growth segments for water technology companies."

However, the challenges posed by industrial wastewater treatment vary greatly from application to application. The goal usually is to separate recyclable materials or pollutants from water which must ultimately meet relevant discharge requirements before being released. Another objective, increasingly, is to condition water so that it can be recycled.

Wastewater purification, too, involves a number of sequentially linked technologies mainly incorporating membranes and requiring reliable particle separation in order to operate efficiently.

The absolute Bloom filter is a dependably regenerative surface filter with a definable, absolute filter fineness in the particle filtration range. It operates with minimal filtration pressure loss, and is configured to achieve an extremely high filtration efficiency. This makes it especially suitable for pre-filtration prior to the membrane.
