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.

What is polyaluminium chloride (PAC)?

Poly aluminium chloride (PAC) used at YASA ET for wastewater treatment projects has the characteristics of good coagulation performance, large alum particles formation, fast settling, low dosage, high efficiency, and wide application range. Due to the positive charge Polyaluminium Chloride (PAC) has strong adsorption of suspended matter in water.

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.

How does polyaluminium chloride affect wastewater treatment equipment?

After the use of Polyaluminium Chloride (PAS), the content of iron, manganese and other heavy metals in water is lowered, which has a little corrosive effect on wastewater treatment equipment.

Is electrocoagulation a viable wastewater treatment alternative?

Electrocoagulation (EC) is a popular wastewater treatment alternative that had been studied extensively for a wide range of wastewater types, due to its versatility, ease of setup, low footprint and eco-friendly nature. The recent studies on EC advancements on various wastewater types had been reviewed in this paper.

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.
