Ultrafiltration treatment of detergent solutions

Taking into account the presented results, it can be stated that ultrafiltration — low pressure membrane process — is suitable for concentration of highly polluted effluents containing detergents. The high separation efficiency of anionic surfactant from model solutions as well as from detergent wastewater was observed. The applied modules were characterized by stable transport and separation properties. In the course of longterm effluent concentration, an essential drop in permeability was not observed and the permeate quality remained almost constant, although of systematic increase in pollution load of the concentrate.
