Polyaluminium Chloride PAC is used as an alternative chemical for aluminum sulfate in the treatment of industrial wastewater, urban wastewater, and domestic water with the main uses of creating coagulants, reducing mud volume. To limit the adjustment of the pH of the source water. To increase the clarity of the water after settling, prolong the filtration cycle and increase the quality of the water after filtration.
Compared with inorganic alum and aluminum sulfate, Polyaluminium Chloride PAC is featured with more advantages, specifically: It does not make the water cloudy when used in over or less quantity. It is easily soluble in water, gives less volatility of the pH in the water, so there is no need to use NaOH for re-treatment, which is less corrosive to equipment. It has 4-5 times greater performance of flocculation and settling efficiency. Less residual Al in water. Better removal of soluble and insoluble organics and heavy metals. It does not generate SO42-(f) content in wastewater after treatment.
