Due to the good stability of spray drying, the PAC has the advantages of wide adaptability to water, fast hydrolysis speed and strong adsorption capacity, and has the advantages of large alum, dense and precipitated precipitates, low turbidity and good dewatering performance. Under the same water quality, the dosage of spray drying polyaluminum chloride is reduced, especially under the condition of poor water quality. The volume of spray drying products can be reduced by half compared with that of the drum drying polyaluminum chloride, which not only reduces the labor intensity of workers, but also more importantly, reduces the user’s water production cost. In addition, spray drying products can ensure safety and reduce water accidents, which is very safe and reliable for drinking water.

Pure white polyaluminium chloride is made from sodium hydroxide aluminum powder and high purity hydrochloric acid by spray drying. The ordinary polyaluminium chloride is made by drying the roller after natural precipitation. And the content of pure white polyaluminium chloride Al2O3 is higher, about 30%. The basicity of pure white polyaluminium chloride is low, only 50%, and that of ordinary polyaluminium chloride is 90%. Pure white polyaluminium chloride has small water insoluble matter, only 0.3%, and ordinary polyaluminium chloride has more than 1%. Pure white polyaluminium chloride does not contain any heavy metals except Al +. Pure white polyaluminium chloride has low iron content and is easy to dissolve at low temperature. It is used in oil-water separation and other projects.
