Abstract:In this study, an integrated air flotation and advanced oxidation process (AOP) facilitated by ×OH, resulting from strong ionization discharge, was applied to address this problem. For this purpose, natural reservoir water was used to culture Scenedesmus dimorphus to prepare synthetic water laden with algae cells concentration of 65.6×104cells/mL, turbidity of 10.8NTU and CODMn of 6.74mg/L, and the applied TRO dosage of 1.03mg/L. Almost complete removal of algae and bacteria (total bacteria, coli bacteria and E.coli) was achieved within 6s, while the CODMn of treated water decreased by 10% from 1.43mg/L to 1.25mg/L, its turbidity decreased by 12.59% from 0.66NTU to 0.54NTU. This suggest that this integrated treatment was effective for treatment of algae-laden wastewater, thus ensuring the safety of water supply.
