What is poly Aluminium chloride (PAC)?

Poly Aluminium Chloride (PAC) is most commonly used in the water treatment industry as a coagulant. It is characterised by the degree of basification – the higher this number the higher the polymer content which equals a more efficient product in the clarification of water products.

Is Pac better than aluminium sulfate flocculant?

Comparing to aluminium sulfate flocculant, the quality of water treated with PAC is better; the total cost reduced by 15%~30%, and the solubility is better. It can be applied to water with broad pH range. The floc function valid in water of pH 5 to pH 9

What are the advantages of using PAC as flocculant?

CAS No.: 1327-41-9 Using PAC as flocculant, the speed of flocs forming and settling is quick. Flocs formed is easy to filter Comparing to aluminium sulfate flocculant, the quality of water treated with PAC is better; the total cost reduced by 15%~30%, and the solubility is better.

How does poly Aluminium chloride work?

Poly Aluminium Chloride is a highly efficient water treatment chemical where it works as a coagulant to extract and clump together contaminants, colloidal and suspended matter. This results in the formation of floc (flocculation) for removal via filters. The below image showing coagulation in action illustrates this process.

What is a polymeric flocculant?

Polymers Polymeric flocculants are high molecular weight organic chains with ionic or other functional groups incorporated at intervals along the chains. Because these compounds have characteristics of both polymers and electrolytes, they are frequently called polyelectrolytes. They may be of natural or synthetic origin.

What is cationic polyacrylamide flocculant?

Cationic polyacrylamide is widely used for municipal sewage treatment. Its sludge dewatering qualities make it the best for sewage treatment. Cationic polyacrylamide flocculant is grouped depending on its levels of ionicity. The ionicity levels include strong, medium, and weak.
