What is a high purity polyaluminum chloride solution?

High purity (Al-b/Al-T > 90%, Al-13 approximate to 70%) and high coneentration (Al-T > 2.0 mol (.) L-1) polyaluminum chloride (PAC) solution was obtained through membrane distillation followed conventional PAC (0.2 mol (.) L-1) synthesis by quick base injection.

What is high-purity poly-aluminum chloride (PACL)?

Poly-aluminum chloride (PACl) is one of the common coagulants for water and wastewater treatment. A new Chinese national standard of PACl has been implemented, where the concentration of insoluble substances, iron and heavy metals is to be controlled strictly, then researches on the preparation of high–purity PACl are needed.

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 .

Why is polyaluminum chloride a good coagulant for water treatment?

Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water .
