Waste Water

Waste water is water that has become contaminated through use. It includes household sewage, municipal waste water, industrial effluent, collected rainwater and surface runoff, i.e. water that flows off paved surfaces. Waste water treatment is generally carried out in three to four stages in centrally located sewage works. The cleaning stages typically include physical, biological and chemical processes. To ensure that the water that leaves the sewage works is genuinely clean, however, a further stage is required to remove pathogenic germs and viruses. This is where ultrafiltration technology can be used to purify the waste water without requiring any additional chemical treatment.


Ultrafiltration not only enables the removal of specific products from complex material streams, it also makes it possible to separate other useful by-products and "pure" water. Reuse concepts can then be applied to recycle these materials within the production process.
