A combination of a submerged membrane filtration system and powdered activated carbon (PAC) was investigated for nonylphenol ethoxylates removal. Both flux initial dosage had significant effects on the micropollutants removal efficiency. The best performance achieved under 20 L/m2.h 50 mg/L. efficiencies obtained at 75±5% in first 60 hours, then decreased 55±7% 23±11% following respectively. As observed, over 65% dissolved organic mass adsorbed into that suspended bulk phase, remainder deposited surface. It reveals between PAC could be an effective solution enhancing from water.
