Poly Aluminum Chloride (PAC)

Poly Aluminum Chloride (PAC) is widely used as a coagulant in various industrial applications. During the water treatment process, PAC is used to remove suspended solids and other contaminants from the surface water.

The advantages of using PAC in water treatment includes

Purifies Water and Effluent better

 

Less sludge is formed or carried

 

Do not require lime with PAC

 

Safer to health

 

Broad flocculation range according to pH (4.5 to 9.0)

 

 

 

 

 

Applications

Water treatment

 

Waste water treatment

 

Sewage treatment

 

Paper and pulp manufacturer

 

Separation of suspended (solids) from effluent water

 

Reduction of BOD and COD

 

 

 

 

Comparison of PAC and Alum

Poly Aluminum Chloride purifies water more effectively and at the same time it is more economical as compared to Poly Aluminum Sulfate (Alum).
