What is poly aluminum chloride (PAC)?

Poly Aluminum Chloride (PAC) is a highly efficient coagulant widely used in water treatment processes, particularly for drinking water and industrial wastewater. Known for its superior flocculation properties, PAC has emerged as one of the most effective and environmentally friendly solutions for purifying water.

Why is PAC used in drinking water & industrial wastewater treatment?

PAC’s widespread use in drinking water and industrial wastewater treatment is due to several key benefits: High Efficiency: PAC has a higher coagulation efficiency compared to traditional coagulants like aluminum sulfate and ferric chloride.

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 poly-Aluminium chloride (PAC) based coagulant?

Poly-aluminium chloride (PAC) based coagulant. It is also used extensively in the pulp and paper processing industry. This product has strong bridge adsorption performance. During the hydrolysis process, condensation, adsorption, precipitation as well as other physical and chemical processes also occurs at the same time.

Why is PAC a good coagulant?

High Efficiency: PAC has a higher coagulation efficiency compared to traditional coagulants like aluminum sulfate and ferric chloride. This means that smaller doses of PAC are required to achieve the same or better results, making it a cost-effective solution for large-scale water treatment.

What is Pac based water treatment?

PAC is the polymer adopted by the Ghana Water Company Limited (GWCL) and the Barekese Water Treatment Plant management in Ghana. However, limited information is available on the optimal dosage and operating conditions for PAC-based water treatment.
