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 PAC?

Polyaluminium chloride PAC is a kind of water treatment chemical with a wide range of uses. It has the advantages of fast flocculation, rapid sedimentation, good solubility and low water purification cost. As a reliable polyaluminium chloride manufacturer in China, we can guarantee the high quality and competitive price.

Is polyaluminium chloride a safe coagulant?

Polyaluminium Chloride is a safer alternative to several other chemical coagulants. For instance, aluminium sulphate has been widely used as coagulant for many years. It removes contaminates and general turbidity from water during the water treatment process.

What is the optimal pH range for Pac coagulation?

The optimal pH range for PAC coagulation performance was 7.5 to 8.0. The coagulation process in conventional water treatment could be enhanced and the ensuing water pH decline reduced appreciably by applying the right dosage of polyaluminium chloride and appropriate process conditions of pH, fluid mixing speed matrix and residence time.

Can polyaluminium chloride be used in drinking water treatment?

Drinking grade polyaluminium chloride (PAC 30%) can be used in drinking water treatment. Polyaluminum chloride is immediately dissolved in water. During the dissolution process, hydroxide ions release a large amount of positive charges to adsorb negatively charged ions in the water.

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.
