Anionic surfactant

Anionic and non-ionic surfactants have been detected in the influents to and effluents from wastewater treatment plants (WWTPs). Linear alkylbenzene sulphonates (LAS) and alkylphenol ethoxylates (APEO) are the most frequently detected anionic and non-ionic surfactants in urban wastewater. The aim of this study was to assess the effect of the presence of anionic and non-ionic surfactants in the influent to WWTPs on activated sludge processes.

Municipal wastewater treatment plants generally utilise biological activated sludge processes to remove organic compounds and nitrogen. The biological nitrogen removal (BNR) occurs in two steps, nitrification (ammonium removal) and denitrification (nitrates removal). This study focused on a medium-sized wastewater treatment plant (WTP) which experienced poor nitrification for years, mainly when the weather temperature drops.
