What is polyaluminum chloride?

Polyaluminum chloride (PACl) is a common inorganic polymeric coagulant used in the water supply and wastewater treatment process , , , , , , . PACl is a dynamic intermediate product in the hydrolysis–aggregation–precipitation process of the Al ion. PACl is composed of several easily intertransformable Al species , , .

What are the advantages of polyaluminum chloride?

Polyaluminum chloride has the advantages of high adsorption activity, wide range of pH value, no need for coagulation aids and no influence of water temperature, etc. It is widely used in water purification treatment of domestic water, industrial water, etc.

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.

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 .

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].

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 (Al T) range.
