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.

What is polyaluminum chloride coagulant?

1. Introduction Polyaluminum chloride (PAC) coagulant has been developed and used in water and wastewater treatment since the 1980s throughout the world (Jiang, 2001). PAC is made by partial hydrolysis of acid aluminum chloride solution using a specific reactor.

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.

What is Pac water treatment chemical?

PAC water treatment chemical has a wider range of applications and is suitable for more types of water quality. 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.

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.

How Pac coagulant can improve the efficiency of sewage treatment?

With the characteristics of rapid reaction speed, PAC coagulant can improve the efficiency of sewage treatment and reduce the water treatment cost. Dosage is small. The configuration concentration is very low, and under the same water quality conditions, its addition amount is also very small compared with other coagulants.
