Whether polyaluminium chloride can be used in the treatment of acidic and alkaline wastewater

As a new inorganic macromolecule coagulant, PAC is a frequent customer in water treatment industry. It has advantages of good stability, wide adaptability to water area, fast hydrolysis, strong adsorption capacity, large alum formation, fast quality and precipitation, low turbidity of effluent and good dewatering performance.

Polyaluminium chloride is widely used as a regulator of industrial acid-base wastewater in recent years due to its wide pH adaptability. The main reason is that polyaluminium chloride is not affected by pH value of water, has strong adsorption and dewatering ability, and has high removal rate of pollutants in water.

Polyaluminium chloride is easy to treat alkaline wastewater because it can fully play the role of polyaluminium chloride under alkaline conditions so that pollutants in water can rapidly coagulate and settle without adding other auxiliary agents.

Usually, in the paper, printing and electronics industries, most of their effluent is acidic. The effect is not very satisfactory when treated with universal polyaluminium chloride. It is necessary to use neutralizer to change the PH value of wastewater. Generally, polyaluminium chloride has good solubility in the range of pH 6-8.

Summary: The treatment of alkaline wastewater is relatively easy, because the role of PAC can be fully exerted under alkaline conditions, and the pollutants in water can rapidly agglomerate and settle. If polyaluminium chloride is used in acidic sewage between normal ranges, there will be no flocculant or poor flocculation effect if the pH value of acidic sewage is too high. Therefore, these other methods need to be replaced. It is necessary to change the value of pH before adding flocculant to treat acidic sewage.
