Production Process And Uses of Polyaluminum Chloride

Polyaluminum chloride is a high-efficiency water purifier that can sterilize, deodorize, and decolorize. Due to its outstanding characteristics and wide application range, the dosage can be reduced by more than 30% compared with traditional water purifiers, and the cost can be saved by more than 40%. It has become a globally recognized excellent water purifier. In addition, polyaluminum chloride 28% powder can also be used to purify drinking water and tap water and other special water treatments, such as removing iron, removing cadmium, removing fluorine, removing radioactive pollutants, removing slick oil, etc. In recent years, polyaluminum chloride has developed into a water purifier with mature technology and large market sales, and has a tendency to gradually replace traditional water purifiers.

Production And Uses of Polyaluminum Chloride in China

At present, the production process of PAC in China is mostly intermittent production, which has serious pollution, low raw material utilization rate and unstable product quality. The development of high-efficiency continuous production processes will surely become a hot spot in the future industrial production research. my country's polyaluminum chloride is mainly used in industrial wastewater. Tap water purification and other fields, the consumption of these two areas accounts for about 70% of the total consumption. The proportion used in industrial sewage purification accounts for more than 40%. The proportion of tap water used in water purification and domestic sewage treatment is about 30%. Industrial circulating water and purification of rivers and reservoirs account for 20%. Others account for 10%. With the country's further improvement of environmental protection requirements, the amount of use in industrial wastewater treatment will continue to increase substantially.

The raw materials used in the current production of polyaluminum chloride are mainly calcium aluminate powder and industrial hydrochloric acid, which are reacted at higher temperature (50-180℃) and pressure (0.5MPa) to prepare a liquid with a base degree of 41.6-98.6% The polyaluminum chloride product is then concentrated and dried to obtain a solid polyaluminum chloride product. The production process of this method is relatively simple, the reaction conditions are also harsh, the equipment requirements are high, and the corrosiveness is strong. Generally, commercially available glass-lined reactors are difficult to adapt, and it is not easy to ensure product quality during production. Mainly used for the treatment of drinking water, industrial water supply, oilfield reinjection water, circulating cooling water and various sewage (such as urban domestic sewage, oily sewage, printing and dyeing sewage, papermaking sewage, steel mill sewage, etc.).

Purchase PAC from A Reliable Manufacturer

In recent years, China's polyaluminum chloride industry has developed rapidly, with more than 500 production enterprises, with a production capacity of 170,000 tons per year in 2005 (calculated as solid products with 30% alumina content). However, the scale of production enterprises is relatively small, and the annual output is mostly 2000-5000 tons. And the regional characteristics of industrial development are obvious, mainly distributed in Henan, Shandong, Jiangsu, Zhejiang and other regions. A base-type industrial cluster has been formed in Gongyi, Henan, with annual output accounting for more than 50% of the country.At Fengbai Chemical Co.,Ltd, we provide world class PAC products that can be shipped to any location around the world.
