At Shanghai Jiao-Tong University, hybrid ultrafiltration membranes have been developed which have an immobilized layer of TiO2. When placed under UV light, these membranes have demonstrated a self-cleaning ability that removes fouling, represented as humic acid (HA). The goal of this project was to evaluate different AOPs for the removal of HA fouling from these hybrid UF membranes. AOPs were tested individually and in combination. Their performance was evaluated based on the membranes flux recovery and the concentration of HA in the permeate. Overall, the best AOP combination was the photocatalysis of TiO2 and the photolysis of H2O2 under UV light. While UV and ozone were effective cleaners as well, ozone alone damaged the membranes by reducing their flux and selectivity.
