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.

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

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.

Does polyaluminium chloride affect microbial community in urban river sediments?

Polyaluminium chloride (PAC) has been widely used as a chemical coagulant in water treatment. However, little is known about the impact of PAC performance on the microbial community in sediments. In this study, the archaeal, bacterial, and fungal communities in urban river sediments with and without PAC treatment were investigated.

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.

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.
