An integrated new method using multi-oxide photocatalyst materials to treat ammonium and phosphate while killing pathogenic microorganisms in poluttion water. This new method involves the simultaneous use of two types of materials: multi-oxides photocatalyst materials ZnO-MgO-TiO2 (MOX) activated under sunlight, forming free radicals hydroxyl/ superoxide to oxidize and kill pathogenic bacteria and fungi. Multi-metallic oxides were modified with rare earth oxides CeO2/La2O3 (DLQDH) to enhance the removal activity of ammonium and phosphate by crystallization process MgNH4PO4 (MAP). The material samples were characterized by XRD, SEM, UV-Vis, FTIR, EDX, XRF...and evaluated the ability to simultaneously removal of ammonium and phosphate, killing typical bacterial strains (Vibrio parahaemolyticus (VP), Staphylococcus aureus (XSA), E. coli - Coliform (EC) present in To Lich river water under sunlight irradation. Ammonium, phosphate removal capacity and bactericidal efficiency results showed that these integration method has potential for practical applications to treat pollution water in the To Lich River as well as other wastewater or agriculture water sources contaminated with ammonium, phosphate and pathogenic microorganisms.
