Abstract

Effect of the powder active carbon (PAC) dosage on ultrafiltration (UF) membrane performance was investigated. The results showed that stable operation time of UF membrane was lengthened and the lowering rate of the flux decreased when the PAC dosage was increased. An addition of PAC has no obvious effect on the membrane filtration resistance. Based on above the experiments, the removal efficiency of organic components in drinking water by combining ultrafiltration and PAC (PAC-UF) was further studied, and contrastively investigated effect of different PAC dosages on the removal efficiency of organic components in 5 drinking water samples with different ingredients. The larger the water sample CODMn was, the higher the average removal efficiency of CODMn; while the CODMn value of outlet water was nearly same. This result indicates that PAC-UF system has a stale effluent and is influenced little by the water quality difference.
