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 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 polyaluminium chloride coagulation?

Polyaluminium chloride, or PACl, is a coagulant used in the water treatment process to remove small particles of dirt and other contaminants. When mixed with untreated water, the PACl sticks to small particles of dirt and other contaminants and clumps them together so they sink to the bottom of the tank. This process is called coagulation.

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 the coagulation removal rate of polyaluminium chloride (PAC)?

Without coagulation removal rates in a single pass of a medium-rate filter were about 50%. This was dramatically improved, to over 90%, by dosing polyaluminium chloride. PAC is directly and continuously dosed from the containers in which it is delivered at a rate of about 0.1ml/m 3 of the circulation flow.

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.
