What is poly-Aluminium chloride (PAC)?

Poly-Aluminium Chloride (PAC)is a kind of highly effective water purificiant, which is wildly used in the purification of table water, industry water, industry circulation water and wasted and polluted water from pharmacy industry, paper making industry and printing and dying industry, as well as life wasted water.

Who makes polyaluminum chloride?

USALCO® has manufactured chemicals for over 60 years, and began full scale production of the patented process (US Patents 5,985,234; 5,997,838; 6,036,935 and Canadian Patent 2229266) for manufacturing Polyaluminum Chloride in 1996. USALCO manufactures a variety of Polyaluminum Chlorides to meet a wide range of water quality objectives.

How to manufacture polyaluminium chloride?

Method for manufacturing polyaluminium chloride with aluminum vanadine and calcium aluminate powder CN104671269A(en) 2015-06-03 Method for producing polyaluminum chloride from hydrogen chloride waste gas and aluminum salt water waste liquid generated from anthraquinone synthesizing production

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 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

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.
