The policy direction of sewage treatment is obvious, polyaluminum chloride will usher in a new round of development

Polyaluminum Chloride (PAC), also known as polyaluminum chloride and polyaluminum, is a multi-nuclear inorganic polymer high-efficiency coagulant containing different amounts of hydroxyl groups. The molecular formula is [Alm(OH)n(H2O)x 】Cl3m-n (n≤3m) has the advantages of good coagulation performance, large floc, low dosage, good sedimentation performance, and low alkalinity consumption in water. It is widely used in the field of water treatment and is a recognized high-efficiency Excellent water purifier.

Polyaluminum chloride was first studied in the early 20th century, but it was actually used in the field of water treatment in the 1970s. At that time, China had just shaken off the shackles of the Cultural Revolution and began to research and develop polyaluminum chloride. After nearly half a century of development, my country has developed into one of the world’s largest polyaluminum chloride production bases. Low prices and fast freight have made China’s polyaluminum chloride products popular in Southeast Asia, the United Kingdom, Africa, Russia, and the United States. , Japan and other dozens of countries and regions, the total industry production capacity exceeds one million tons (equivalent to solid content).

Polyaluminum chloride is mainly divided into two categories: industrial-grade polyaluminum chloride and drinking water-grade polyaluminum chloride. Among them, industrial-grade polyaluminum chloride is often used as a flocculant for industrial wastewater and sludge treatment; drinking water-grade polyaluminum chloride Polyaluminum chloride can be used for the purification treatment of special water quality such as drinking water and tap water, such as iron removal, fluoride removal, floating oil removal, etc. At present, according to the “In-depth Market Research and Investment Strategy of Polyaluminum Chloride Industry 2021-2025” released by the Industrial Research Center, Polyaluminum chloride in my country is mainly industrial-grade polyaluminum chloride, and the production capacity of industrial-grade polyaluminum chloride accounts for more than 75% of the total production capacity.

In recent years, the policy orientation of the sewage treatment industry has been obvious, and my country’s sewage purification agent industry has achieved rapid development, which has led to an increase in investment enthusiasm in the polyaluminum chloride industry, and an increasing number of industry reconstruction, expansion and new projects. For example, in January 2019, Kemira Tiancheng Wanfeng Chemicals (Yanzhou) Co., Ltd. held a groundbreaking ceremony for its 40,000-ton-annual polyaluminum chloride construction project; in September 2019, Guangxi Baise and Xinjiang Wujiaqu Pengxiang Building Materials Co., Ltd. signed a contract for a polyaluminum chloride project with an annual output of 250,000 tons; in March 2020, the 100,000-ton annual polyaluminum chloride project contracted by Shanxi Huanpu Chemical Co., Ltd. started construction; in October 2021, Yunnan Longmagnesium’s annual output A signing ceremony was held for the 50,000-ton polyaluminum chloride project.

Industrial researchers believe that in recent years, my country has made great progress in the control of industrial pollution. The overall amount of industrial wastewater discharge showed a downward trend. However, the continuous development of social economy and the continuous advancement of new urbanization have caused the volume of wastewater discharge to remain at a relatively high level. As a coagulation water purification agent widely used in water supply and drainage treatment, polyaluminum chloride has good market prospects, and the industry will welcome Come to a new round of development opportunities.
