There is an increasing demand for drinking water, that is purified without applying chemical additives such as chlorine. The ultrafiltration technique provides a mechanical treatment technique that removes particles as well microorganisms, e.g. bacteria and viruses, from the water. Even waters with high turbidity can be treated. Thus, ultrafiltration is the appropriate method for the purification of bank-filtered water, karst water and surface water.

Ultrafiltration uses pressures of up to 10 bar. The pore size of 1 nm to 0.05 µm guarantees the hygienic treatment of washing and process waters containing oil and grease phases.
