Treatment volume of grey water approx. 3100 litres/day

The grey water from showers, bathtubs and washbasins is first pre-filtered by a PR 150-S PURAIN filter before it is fed into a 5,000-litre plastic tank (bioreactor), where biodegradation takes place. The skimmer overflow of the PURAIN filter removes impurities from the water surface. With the help of two AQUALOOP membrane stations with C-MEM™ technology in the bioreactor, the grey water is ultrafiltrated and then fed into a 5,000-litre clear water storage tank. In this project, the grey water treatment system is implemented as an internal tank system.
