  • 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.

  • Poly-Aluminium-Chloride (PAC) - 3V Tech

    Water treatment - The poly aluminium chloride (PAC) is used for settling of solid particles present into drinkable waters and for the flocculation of civil and industrial effluents. It has also a high antibactericide effect, due to the presence of chlorine into the product formula, and can be utilized for large range of pH and with higher turbidity.
