Purify domestic drinking water and domestic sewage. 2. Purification of industrial water, industrial wastewater, mine, oil field reinjection, purification of water, treatment of gold, coal washing, leather and various chemical wastewater treatment. 3. Industrial production applications; paper sizing, printing and dyeing, cement accelerators, precision casting hardeners, refractory adhesives, glycerin refining, cloth anti-wrinkle, medicine, and other industries. Wastewater can be recycled. 4. In the refining industry, it is used for waterless separation with very good effect.

    Production Methods

    Boiling pyrolysis method: The crystalline aluminum chloride is subjected to boiling pyrolysis at 170℃, and the released hydrogen chloride is absorbed into water to make 20% hydrochloric acid and recovered. Then add water to ripen and polymerize above 60 ℃, and then solidify, dry, and crush to obtain a solid polyaluminum chloride finished product. In its boiling pyrolysis method, aluminum ash (the main components are alumina and aluminum) is added to the reactor with pre-added washing water according to a certain ratio, and hydrochloric acid is slowly added to the polycondensation reaction under stirring, which is polymerized to pH after aging. 4.2 to 4.5, the relative density of the solution is about 1.2 to settle, to obtain liquid polyaluminum chloride. The liquid product is diluted and filtered, evaporated, concentrated and dried to obtain a solid polyaluminum chloride finished product. its
