Surfactants are the major active ingredients of laundry detergents. Therefore, special attention should be focused on the treatment and disposal of laundry wastewater. The aim of this study was to characterise the wastewater from a commercial laundry over 30 days. Physicochemical analyses were performed, monitoring the content of nitrogen, phosphate, heavy metals, linear alkylbenzene sulphonate (LAS), volatile organic acids and alcohols. The pH was approximately 5.6 and the COD… Expand

Evaluation of anionic surfactant removal by anaerobic degradation of commercial laundry wastewater and domestic sewage
TLDR
Statistical tests indicated that the decrease of the LAS removal rate was significant and indicated a correlation between the removal of LAS and specific organic loading rate and genera similar to Geobacter, Desulfovibrio, Syntrophomonas, and Desulfomonile, which were related to the degradation of L AS.
