Abstract
This paper presents a comparative study of the elimination of anionic surfactants (linear alkylbenzene sulphonates, LAS) and nonionic surfac tants in a conventional municipal activated sludge plant. The LAS were analysed by high performance liquid chromatography, after extraction and purification. The nonionic surfactants was analysed by the Wickbol d method. The elimination of the surfactants in water, suspended solid s and sludges were determined in the different stages of the purificat ion process. The results obtained show that over 90% of the surfactant s were eliminated. The maximum degradation took place in the aeration tank. (C) 1997 Elsevier Science Ltd.
