The first major use of aluminum sulfate is for papermaking, and the second major use is as a flocculant in the treatment of drinking water, industrial water and industrial wastewater, which accounts for about 40% of the total aluminum sulfate production. When aluminum sulfate is added to this type of water, colloidal aluminum hydroxide flakes can be formed that can adsorb and precipitate bacteria, colloids and other suspended matter, and can be used to control the color and taste of water in drinking water treatment. Zibo Guangzheng Aluminum Salt Chemical Co., Ltd. is mainly engaged in the production and sales of paper-making industrial aluminum sulfate, iron-free aluminum sulfate, and water treatment agent aluminum sulfate.
