title: [Removal of TOC and Ames mutagens from drinking water using AC-NF process].
abstract: Expermental results of the effect and mechanism of removing TOC and Ames mutagens from drinking water using AC-NF process showed that the adsorptive ability of AC was limited, depending on the characters of AC and the organic matters in drinking water. But AC can be used as the pretreatment of NF to ensure to meet the requirement of membrane feed. NF can remove the majority of total organic carbon and Ames mutagens effectively to ensure the safety of drinking water. The MR values of TA98 and TA100 of NF permeate were below 2 under the tested doses, and the results of Ames test of NF permeates were completely negative. Therefore, it is feasible to combine AC and NF to obtain the high-grade drinking water.
