Can polyaluminum chloride be used in water treatment?

In this study, synthesis and speciation of polyaluminum chloride (PAC) for application in water treatment was investigated using a colorimetric speciation method. It was possible to produce stable preparations of PAC solutions in which a relatively stable cationic polymer predominated.

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 polyaluminium chloride a safe coagulant?

Polyaluminium Chloride is a safer alternative to several other chemical coagulants. For instance, aluminium sulphate has been widely used as coagulant for many years. It removes contaminates and general turbidity from water during the water treatment process.

Is there an alternative preparation procedure for polyaluminium chloride (PAC)?

An alternative preparation procedure for polyaluminium chloride (PAC), a common inorganic coagulant, is presented in this paper.

What is polyaluminium chloride used for?

Among the aforementioned products, polyaluminium chloride has become one of the most effective coagulant agents in water and wastewater treatment facilities with various applications, including removal of colloids and suspended particles, organic matter, metal ions, phosphates, toxic metals and color.

Can granular al be used to produce polyaluminium chloride?

An alternative way for the production of PAC should be desirable, resulting in a more effectively preparation route, regarding time and cost. In this paper, an alternative method for producing polyaluminium chloride is presented, based on the use of granular Al, as aluminium source.
