L. Q. T. Nguyen*, M. Engelhart, M. Wagner, P. Cornel, Technical University Darmstadt; Germany; E. Linclau, P&G, Belgium

This paper presents an integration of filtration process into a liquid detergent production plant to separate surfactants from rinsing waters discharged during the production of fabric enhancer and shampoo. There are three research objectives: (i) to minimize the waste stream, (ii) to reduce the high organic load in the downstream and (iii) to recover valuable materials, simultaneously. Due to the difference of rinsing waters resulting from different production lines, flow separation at source is necessary for further treatment steps...
