The pressurized ultrafiltration technology were applied to treat Xijiang source water. The effluent quality of ultrafiltration technology was evaluated. The variation of transmembrane pressure (TMP) during the experiment was also studied. Finally, we in-vestigated the chemical cleaning method .The results showed that the treated water quality by the pressurized ultrafiltration tech-nology was steady and safe. The concentrations of CODMn,ammonia nitrogen, turbidity in the effluent could still meet the sanitary standard for drinking water (GB5749-2006) and water quality standards for fine drinking water (CJ94-2005). When the membrane is run under the best membrane flux, the TMP increased slowly. The membrane fouling could be controlled effectively by chemi-cal cleaning with HCl and NaClO.
