Which reagent is used to prepare high-concentration polyaluminum chloride (PACL) products?

Using an instantaneous base-feeding method and a batch-feeding method, high-concentration polyaluminum chloride (PACl) products were prepared employing CaO as the basification reagent. The distribution and transformation of the Al species of PACl was explored for the first time over a broad total Al concentration (AlT) range.

How many suppliers of polyaluminum chloride?

Global ( 68)Suppliers POLYALUMINUM CHLORIDE | 101707-17-9 – chemical and physical properties, structure, melting point, boiling point, density, molecular formula, molecular weight, uses, prices, suppliers, and toxicity/safety/hazards/SDS information.

Which polymer is used in polyaluminum chloride?

The most well known polymeric Al species in polyaluminum chloride (PACl) is the preformed Al 13 polymer which is obtained by the method of base-microinjection into AlCl 3 solution [6, 7].

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 .

What is the basicity of polyaluminum chloride?

Polyaluminum chloride (PAC) is the name given to the family of compounds defined by the formula: Where 0 < n ≤ 3m and where m ≥ 1. The degree of neutralization (i.e., the OH to A1 ratio) is known as the basicity. In the case of polyaluminum chlorides the basicity is defined by the formula n/3m.

Do polyaluminum chlorides cause membrane fouling?

Without being bound by theory, these observations suggests that polyaluminum chlorides participate in a process that causes membrane fouling as the basicity increases and that this fouling process is mitigated as the temperature is increased.
