What is poly aluminum chloride?

Poly aluminum chloride is a water purification material, inorganic polymer coagulant, also referred to as Poly aluminum, abbreviated as PAC, an inorganic polymer water treatment agent having a relatively large molecular weight and a relatively high charge is produced due to bridging action of hydroxide ions and polymerization of polyvalent anions.

What is polyaluminium chloride?

Polyaluminium chloride, also written as poly aluminium chloride, is an inorganic polymer coagulant used for water treatment. Take the first letter of words as abbreviation, it is refered to as PAC chemicals, can be considered as one of the best coagulants.

What is the chemical formula for polyaluminum chloride?

Polyaluminum chloride can be regarded as an intermediate product of the hydrolysis of AlCl3 into Al (OH)3, so that the hydrolysate is acidic. Polymeric aluminum chloride is also known as aluminum hydroxychloride (aluminum chloride) or Basic aluminum chloride (Basic aluminum chloride), and its chemical formula is [Al2 (OH)nCl6-n] m.

What are the physical and chemical properties of polymeric aluminum chloride?

The residual amount of aluminum and salt in the treated water is less, which is beneficial to ion exchange treatment and preparation. The main physical and chemical properties of polymeric aluminum chloride are expressed in terms of alkalization degree, pH value, Al2O3 content and density.

How many types of polyaluminium chloride are there?

There are four types of polyaluminium chloride for sale with different content of AL2O3 and basicity. Among them, PAC 30% 01&02 is used for drinking water treatment, while PAC 30% 03&PAC 28% 04 is used for industrial wastewater treatment. The four types can be easily distinguished by color, from white, light-yellow to deep-yellow.

What is the molecular formula for aluminum chloride?

polymeric aluminum chloride is an inorganic polymer coagulant, molecular formula [Al2 (OH)nCl6-n-xH2O]m (m = 10,n = 1~5). It is an inorganic polymer compound, which is a hydrolysis product between aluminum chloride and aluminum hydroxide.
