Submerged membrane filtration process coupled with powdered activated carbon for nonylphenol ethoxylates removal

A combination of a submerged membrane filtration system and powdered activated carbon (PAC) was investigated for nonylphenol ethoxylates removal. Both filtration flux and initial powdered activated carbon dosage had significant effects on the micropollutants removal efficiency. The best performance...
