Abstract

Studies the removal of pollutants from drinking water with combined PAC-Immersed hol- low fiber membrane system and compares the efficiencies of removal of pollutants before and after the immersion of PAC in the IHFMS system which contain hollow fiber membrane, and points out that at the concentration is 250mg/L, PAC takes 40 min to get in contact with water, and the ultrafiltration membrane flux is 12L/h, and concludes from test results that the addition of PAC im- proves the removal of CODMn and NH+4-N in IHFMS but does not change the removal of UV 254 too much, and concludes from test results that the addition of PAC can effectively reduce the membrane resistance and maintain a high flux for a long period of time.
