Can PAC be prepared from aluminum chloride solution?

PAC can be prepared from aluminum chloride solution with the titration of various basification agents such as calcium oxide [16, 21], sodium hydroxide [, , ] and sodium aluminate .

How much sulphate is added to a polyaluminium chloride reaction?

A process according to claim 10, characterised in that the reaction mixture is supersaturated into the metastable region, and the added amount of sulphate to the reaction mixture is kept belowabout 1.0 weight percent, calculated on the total weight of the produced polyaluminium chloride solution.

What is the basicity of polyaluminium chloride?

Basicity of the Produced PAC OH − is the basic component influencing the morphology of polyaluminium chloride [6 – 9] whose index in PAC is measured by basicity (B). According to GB 15892-2003 (water treatment chemical-polyaluminium chloride) , basicity can be measured.
