Abstract

A sequencing batch reactor (SBR) was operated to investigate the degradation and removal of non-ionic surfactant, nonylphenol ethoxylates (NPEOs) in wastewater using lab scale experimental apparatus. About 5mg/L of NPEO was introduced and only < 0.1mg/L of NPEOs and nonylphenol(NP) in total was detected in treated effluent. In the effluent, long chain ethoxylates (NPEO12-15) were not detected, but short chain ethoxylates (NPEO1,2) were in relatively high concentration. NPEOs in the mixed liquor disappeared more rapidly in anaerobic condition than in aerobic condition.
