The aim of the study was to evaluate the suitability of UF membranes for purification and concentration of effluents from detergent production. During preliminary experiments flat-sheet Amicon (the cut-off of 100, 50, 1 and 0.5 kDa) and Intersep (the cut-off of 30, 10 and 4 kDa) membranes were used. Semi-pilot and full-scale cross-flow experiments were performed using Koch/Romicon capillary ultrafiltration mod-ules with polysulfone membranes of the cut-off of 2 and 5 kDa. The results obtained indicate that a decrease of membrane cut-off value improves the efficiency of effluent treatment. The membrane with a cut-off of 0.5 kDa yields the best separation efficiency: the decrease of COD-Cr value is over 85%, which corresponds to COD-Cr of permeate equal to 8800g O2/m3. It has been found that UF capillary modules made by Koch/Romicon are suitable for concentration of highly polluted effluents containing detergents. The modules applied are characterised by stable transport and separation properties. In the course of a long-term concentration of effluents, an essential drop in a permeability was not observed and the permeate quality remained almost constant, although a systematic increase in pollution load of the concentrate occurred.
