Treatment of Micro-Polluted Water Resources by Powdered Activated Carbon-Ultrafiltration Membrane

Fan Jin-chu

Abstract

The powdered activated carbon(PAC)-ultrafiltration membrane process was used to treat micro-polluted water resources,in terms of the efficiency of organics removal,enhancing flux and effect of preventing membrane from fouling.It was found that PAC addition was effective in enhancing flux and that flux could be recovered by backwash,suggesting that PAC can prevent membrane from fouling.The process could remove organics and disinfections by-productions(DBPs)due to effective removal of lower molecular weight(MW)by PAC.
