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 .

Is PAC a good flocculant?

The floc function valid in water of pH 5 to pH 9 Comparing to inorganic flocculants, PAC is suitable for water of broad temperature, and is functional in low temperature water. It reduces less basicity less, so less or no basifier needed. The corrosivity of PAC is lower, easy to transfer, handle and operate.

Is Pac better than aluminium sulfate flocculant?

Comparing to aluminium sulfate flocculant, the quality of water treated with PAC is better; the total cost reduced by 15%~30%, and the solubility is better. It can be applied to water with broad pH range. The floc function valid in water of pH 5 to pH 9

Which PAC is the best recoagulant?

It is the best choice from aluminum sulfate, aluminium chloride to polyaluminium chloride PAC. The solid powdered PAC from us is made by excellent spray drying technology. It is used as a recoagulant in drinking water purification, as an antiperspirant in deodorants and flocculant in waste water treatment.

What is polyaluminium chloride used for?

Polyaluminium chloride (aluminium chlorohydrate) also simply called PAC, is used in deodorants and as a coagulant in water purification. This compound is preferred in some cases because of its high charge, which makes it more effective at destabilizing and removing suspended materials than other aluminium salts. CAS No.: 1327-41-9

What are the advantages of Pac compared to inorganic flocculants?

Comparing to inorganic flocculants, PAC is suitable for water of broad temperature, and is functional in low temperature water. It reduces less basicity less, so less or no basifier needed. The corrosivity of PAC is lower, easy to transfer, handle and operate. Drinking water and sanitary sewage.
