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 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 polyaluminium chloride?

Polyaluminium Chloride is a yellow colored, water soluble solid with the chemical formula [Al2 (OH)nCl6-n]m. The chemical comes in the forms Polyaluminium Chloride (PAC) 28% and Polyaluminium Chloride (PAC) 30%. Polyaluminium Chloride has many industrial uses but primarily it is used in the processes of flocculation in water treatment industries.

How to use polyaluminium chloride PAC coagulant in sewage treatment process?

Most industries need to use polyaluminium chloride PAC chemical in the sewage treatment process. The precipitation rate of PAC chemical is much faster and the precipitation effect is better. The use method of PAC coagulant is to dissolve it in a certain proportion and then add it to water.
