Poly aluminum chloride plays an important role in the development of water treatment Poly aluminum chloride is mainly used as flocculant for domestic drinking water, domestic water and industrial sewage (such as oily wastewater, printing and dyeing, papermaking wastewater, steel mill wastewater, etc.) As well as the treatment of highly toxic heavy metals and fluorine-containing sewage, etc. In addition, it has a wide range of uses in precision casting, tanning, etc. Since its establishment, PAC producers have been devoted to promoting the development of China's water and water utilities. During this period, we have done a lot of training, publicity and promotion for the establishment of the philosophy of water and we will continue to do so. The new China Water Art Network is China's leading water industry vertical e-commerce service provider, dedicated to the water industry as a whole to create their own exclusive marketing platform for Chinese water art colleagues to provide the best water treatment technology solutions, Project cases, academic research and best practical skills; at the same time, it provides a platform for technology exchange and communication among water art engineering design institutes, constructors and equipment manufacturers; and provides professional, precise, effective and individual integrated marketing programs for enterprise users , Jointly promote the sustainable development of China's water industry. Poly aluminum chloride has developed rapidly in recent thirty years. At present, the world's output has reached about 1.5 million t / a. Calculated on the basis of 10% alumina, of which about 500,000 t / a in Japan, about 400,000 t / a in China, Others are developed countries. At present, the domestic polyaluminium chloride technology has reached or reached the international advanced level, with resources and technical advantages. As a whole, China's polyaluminum chloride enterprises are small and medium-sized with more than 300 manufacturers and the total output Has more than 400,000, all over the country in various provinces and cities, the largest production of liquid production plant has reached an annual output of more than 20,000 tons, the largest manufacturer of solid aluminum chloride has reached 5,000 tons of sales, its application areas in addition to tap water purification, industrial Water treatment, sewage, waste and sludge treatment, but also used in foundry, medicine, catalyst, cosmetics, paper and leather and other non-water treatment industry, therefore, polyaluminum chloride in the water treatment industry plays an important role.
