    Effect of polyaluminium chloride water treatment sludge

    In this study, the reuse of polyaluminium water treatment sludge (PA-WTS) as a flocculant aid to improve the effluent quality of wastewater during primary sedimentation is evaluated and presented. PA-WTS was collected from Gabba water treatment plant (Gabba WTP) Uganda, after the coagulation-flocculation process that makes use of aluminium

    Impacts of poly-aluminum chloride addition on activated

    As a common and low-cost coagulant, poly-aluminum chloride (PAC) may be widely used for wastewater treatment. In this article, the impacts of PAC on activated sludge and the treatment efficiency of sequencing batch reactor were investigated over 100 d for domestic wastewater treatment.

    (ACH) and polyaluminium chloride (PAC) do not have as great an effect as that of alum in respect of water alkalinity and pH. Organic coagulants generally do not effect the raw water alkalinity and pH. All coagulants produce sludge in the form of the metal hydroxide together with coloured and colloidal mater removed

    Appraisal and ranking of poly-aluminium chloride, ferric

    Three coagulants that are commonly used in water and wastewater treatment were examined in the study – poly-aluminium chloride (PACl) (18% Al 2 O 3), ferric chloride (FeCl 3) (40% w/w) and aluminium sulphate (Al 2 (SO 4) 3) (8% Al 2 O 3). All coagulants were in liquid form to ensure full mixing with the DSW.

    USING POLYALUMINIUM COAGULANTS IN WATER TREATMENT

    At one water treatment plant in the Otway region of Victoria, polyaluminium chloride replaced alum and in so doing SO 4 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.

    Effects of polyaluminium chloride on the freshwater

    Effective concentrations of polyaluminium chloride can differ markedly according to the type of water composition used in the assay. Our experiments proved that EC50 values can fluctuate between 9.89 and 54.29 mg·L−1 of Al3+, and the toxicity is dominantly dependent on the treated water conductivity. This parameter seem...

    We also have coagulants such as polyaluminium chloride (PAC) and ferric chloride. With our experience and competence, we are able to work flexibly to develop an effective concept for each unique application. It is based on a one-, two- or three component system, depending on the actual conditions in the specific water or sludge.
