Abstract

In this study the separation of model solutions of CIP (cleaning in place) waste water was investigated experimentally. The ABS (alkyl benzene sulphonate) was chosen as anionic detergents applied in the CIP processes. The ABS solution was treated by combined ultra- and nanofiltration steps, the detergent was recovered, concentrated over 100 g dm-3 and this concentrate could be led back to the process. The ABS content of the permeate was kept below the desired 0.5 g dm-3 value. The resistance in series model described well the concentration profile of surfactant and the permeate flux of the ultrafiltration step.
