What is Pac based coagulant?

Poly-aluminium chloride (PAC) based coagulant. Accepta PAC is used for the treatment of wastewater and industrial effluent, drinking water, swimming pool water, the treatment of sewage and industrial effluents. It is also used extensively in the pulp and paper processing industry. Poly-aluminium chloride is…

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.

What is the treatment capacity of polyaluminium chloride?

Its treatment capacity is 1.3-3.0 times of other inorganic flocculants. The PAC (Polyaluminium Chloride) enjoys wide-range adaptability for different-temperature source water and a good solubility. PAC is slightly corrosive and easy for operation, and it is suitable for automatic dosing.

What is PAC (Polyaluminium chloride)?

The PAC (Polyaluminium Chloride) enjoys wide-range adaptability for different-temperature source water and a good solubility. PAC is slightly corrosive and easy for operation, and it is suitable for automatic dosing. Furthermore, it will not block pipes over long-time usage.

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.

What is the optimal pH range for Pac coagulation?

The optimal pH range for PAC coagulation performance was 7.5 to 8.0. The coagulation process in conventional water treatment could be enhanced and the ensuing water pH decline reduced appreciably by applying the right dosage of polyaluminium chloride and appropriate process conditions of pH, fluid mixing speed matrix and residence time.
