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 is Longwater® polyaluminium chloride (PAC/PACL)?

CAS No.:1327-41-9 EINECS No.:215-477-2 Chemical Formula: [AL2 (OH)nCL6-n] Longwater® Polyaluminium Chloride (PAC/PACL) as a kind of high effective inorganic compound polymer coagulant or flocculant. Longwater® All the polyaluminium chloride is manufactured by National Standard and almost equal to ANSI/AWWA Standard, JIS Standard, NSF Standard.

What is Pac water treatment?

Powdered Activated Carbon (PAC) is a reliable and economical water treatment option for taste and odor control and removal of organic compounds. The use of PAC is beneficial economically and environmentally, since it reduces operating costs, produces minimal waste sludge, allows for the conservation of resources, and provides superior water quality.

Is Pac better than alum for water treatment?

Nevertheless, in the view of physical–chemical treatment, this study shows that PAC is more efficient in improving physical parameters of partially stabilized leachate and less effective in removing COD compared to alum; perhaps for this reason, PAC is increasingly recommended for water treatment where COD is not a significant concern.

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

Can PAC be applied to water with broad pH range?

It can be applied to water with broad pH range. 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.
