  • USING POLYALUMINIUM COAGULANTS IN WATER

    2017-8-1 · At one water treatment plant in the Otway region of Victoria, polyaluminium chloride replaced alum and in so doing SO4 levels in the treated water were reduced from 27 to 4 - 5 mg/L. Previously, alum was dosed at 45 to 55 mg/L at this plant. The change to PACl had a major impact on SO4 levels in the sewage, with reduced odour problems evident at several pump stations in the sewerage system.
