Pollutant removal of drinking water with combined system of PAC-UF

Wang Xiao-lian

Abstract

In order to improve the removal efficiency of pollutants by ultrafiltration(UF) membrane,the experiment has been carried out based on the combined use of adsorption of powered activate carbon(PAC) and filtration of UF for advanced treatment of drinking water.The results showed that UF could remove turbidity effectively,while it could not remove dissolved organic matter and lower molecular weight pollutants well.Adding PAC to the system enhanced the removal efficiency of UF for COD_(Mn),UV_(254) and the larger the amount of PAC added,the higher the removal efficiency.It also showed that under the same addition amount of PAC,the organic content of effluent decreased firstly and then was steady during the course of the operation.
