A New Flat-Sheet Submerged Membrane Photoreactor (FSMPR) for the Removal of Humic Acid in Water
The study focuses on the degradation humic acid (HA) by a hybrid system combining a flat-sheet submerged membrane module and a photocatalysis reactor (FSMPR). The influences of UV irradiation intensity, titanium dioxide (TiO2) and initial humic acid concentration, pH, H2O2 dosage were investigated in batch kinetic tests. and the relevant dynamic analysis was carried out. The transmembrane pressure (TMP) with time under the range of constant flux operation (20-40L/m2h) does not increase obviously. It was also found that aeration backflush availably reduced TMP of the FSMPR. Therefore, the FSMPR can be potentially applied in drinking water treatment.
