Water treatment chemicals, also known as water treatment chemicals, mainly refers to industrial water treatment chemicals used, including cooling water, boiler water, sewage, water and other industrial water treatment field with the scale inhibitor, corrosion inhibitor, dispersing agent, disinfection of algal agents, defoamers, flocculants, oxygen scavenger, sludge conditioning agents, chelating agents, etc.. Raw water and wastewater treatment coagulant and flocculant used is also included in the water treatment chemicals. In addition, activated carbon and ion exchange resins are also important water treatment chemicals.

Statistics in a foreign country, the water treatment agent, including the following three categories of products:
1. Chemicals: the former refers to inorganic chemical products for water treatment, such as aluminum sulfate.

2. Specialty Chemicals: including carbon, ion exchange resins and organic polymer flocculants (such as polyacrylamide, polyethylene and poly quaternary amine), etc.;

3. Formulation of chemicals: including corrosion inhibitors, scale inhibitors, bactericides and combustion additives.
Water treatment chemicals worldwide sales in 1992 to 2.837 billion U.S. dollars (not including activated carbon, ion exchange resins, additives and general inorganic combustion coagulant), which was 1.479 billion U.S. dollars the United States, Western Europe, 483 million U.S. dollars, Japanese 575 million U.S. dollars. According to statistics, the United States, more than 500 water treatment agent in the production and services companies, technology service oriented. Water treatment market in Western Europe mainly by U.S. companies control only a few Western European countries water treatment company. Western Europe, the organic polymer flocculant, especially with certain polyacrylamide products, coupled with inadequate capacity of the U.S. powder products,The market was largely occupied by the Western European companies, other Western European companies also took from the hands of the Japanese factory fresh and the Middle East part of the Korean market. Japan engaged in manufacturing water treatment chemicals and technical services companies are many, and cooling water treatment chemicals manufacturing and technical services and the company has more than 20.

Water treatment technology in China starting in the 50's, from the former Soviet Union, while the introduction of chemical technology has begun to use inorganic phosphate as water treatment agent. 70's introduction of large chemical fertilizer unit in the same water treatment technology was introduced, mainly to introduce the United States Bates's technology, the early 80s and from the U.S. introduction of phosphate water treatment company Nalco technologies and companies from Japan, Kurita T-225 Alkaline introduced treatment formula. On this basis, the development of China-made office line of water treatment technology and water treatment agent, sewage treatment technology from the 60's a start, now they use a secondary treatment, Flocculant and coagulant that already started production from the 50s, but 60 years before being applied to industrial production, 80 years developed a number of new agents. The production of organic flocculant polyacrylamide products to the main varieties of non-ionic and anionic mainly small cationic product. Which yield a larger, more plant species are South Africa and plastic factory in Guangzhou. By 2000, all water treatment chemicals with the exception of species in the preparation of a breakthrough technology, the production and application of the varieties now still dominant. Average annual growth rate of various species will be around 5% -6%.
