文摘

Blocking models and interaction energy theory were employed to evaluate PAC alleviating membrane fouling. Cake formation was the major mechanism of membrane fouling. PAC pre-treated water had a relatively low fouling rate. PAC enhanced the removal of NEU and SHA (based on fractionation), and BB&LMW-A (based on HPSEC). PAC could control membrane fouling through decreasing AB interaction energy.
