drinking water grade poly aluminium chloride reaction using method

  • USING POLYALUMINIUM COAGULANTS IN WATER

    2017-8-1 · Another important advantage of using polyaluminium coagulants in water treatment processes is the reduced concentration of sulphate added to the treated water. This directly affects SO4 levels in domestic wastewater. A raw water with a sulphate level of 3 to 5 mg/L will typically have a SO4 concentration of 15 to 25 mg/L following treatment with alum.

  • White drinking grade Poly aluminum chloride(PAC)

    2017-7-11 · Subsequent to the various coagulants, the advantages of using PAC over alum are, PAC works well with pH range of 6-9 where as alum works better between pH 6.5-7.6, since, PAC works even at temperature below 10DC, so, it can be used during winter season. Also, quality of treated water is good, and possesses greater reaction speed due to its liquid state. Further, it works at all turbidities and contains lower residual aluminium content. Polyaluminium coagulants are typically twice the price of liquid alum on per kilogram aluminium basis. However, lower doses of the coagulant and lower pre- and post-treatment alkali doses can still make its use economical. Polyaluminium chloride …
