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 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.

What is polyaluminium chloride used for?

Polyaluminium chloride (aluminium chlorohydrate) also simply called PAC, is used in deodorants and as a coagulant in water purification. This compound is preferred in some cases because of its high charge, which makes it more effective at destabilizing and removing suspended materials than other aluminium salts. CAS No.: 1327-41-9

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 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.

How does PolyDADMAC work?

PolyDADMAC can strengthen the “net structure” formed by inorganic coagulant in water treatment to effectively capture fine suspended matter, especially in high turbidity or highly polluted water. 1.
