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 .

Does Contec use polyaluminium chloride in potable water treatment?

Polyaluminium Chloride Argentina, where PAC is not used at all as flocculants in potable water treatment, Contec has built two PAC plants and in 5 years almost all the drinking water is treated with PAC. Poly Aluminium Chloride process has been fine tuned by Contec during these years.

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

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.

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.

What is polyaluminum chloride (PAC)?

Polyaluminum chloride (PAC) is an important flocculant in potable water and wastewater treatment. Al13 or Alb is regarded as the most efficient species of PAC. A low base addition rate, small base drop sizes, and sufficient mixing usually favor the formation of PAC with higher Alb contents.
