Why is polyaluminum chloride a good coagulant for water treatment?

Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water .

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.

Can PAC be used as coagulant for water treatment?

The ZPD value of PAC was also revealed that the flocculation tendency of PAC particles was very high in water, and the PAC could be used as coagulant for water treatment. Fig. 5.

Can PAC reduce sludge production during water treatment?

The formation of sludge during water treatment is a concern both environmentally and economically. PAC’s ability to curtail sludge production not only simplifies the disposal process but also aligns with sustainable practices, reducing the ecological footprint of water treatment operations.

Is Pac better than aluminium sulfate flocculant?

Comparing to aluminium sulfate flocculant, the quality of water treated with PAC is better; the total cost reduced by 15%~30%, and the solubility is better. It can be applied to water with broad pH range. The floc function valid in water of pH 5 to pH 9

How does PAC affect water treatment?

This article delves into the various dimensions of PAC’s influence on water treatment, exploring its impact on coagulation, versatility, sludge reduction, turbidity removal, pH resilience, settling efficiency, cost-effectiveness, and compliance with water quality standards.
