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 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.

Is polyaluminium chloride better than polyelectrolyte – alum-based coagulation?

At the Barekese Water Treatment Plant in Ghana, an alternative, the polyelectrolyte – polyaluminium chloride (PAC) is also used in coagulation but limited information is available on the operating conditions required to achieve better performance than alum-based coagulation.

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.

Are PACL coagulants a good coagulant?

Results from the pilot-scale study indicate that most PACls were as or more efficient a coagulant as alum for direct filtration of surface water without requiring acid addition for pH adjustment and subsequent base addition for re-stabilizing the water.

Does polyelectrolyte –polyaluminium chloride Formance improve coagulation performance in water treatment?

At the Barekese Water Treatm ent Plant in Ghana, an alternative, the polyelectrolyte –polyaluminium chloride formance than alum-based coagulation. The aim of this study was to determine the optimal coagulant dose, mixing speed and operating pH for enhanced performance in water treatment.
