Water treatment chemicals mainly refer to chemicals used in industrial water treatment, including scale inhibitors, corrosion inhibitors, dispersants, antiseptics, algaecides, and defoamers used in industrial water treatment such as cooling water, boiler water, sewage, and oil field water. Agents, flocculants, deoxidizers, sludge regulators, chelating agents, etc. Coagulants and flocculants for raw water and sewage treatment are also included in water treatment chemicals. In addition, activated carbon and ion exchange resins are also important water treatment chemicals.
Classification of Water Treatment Agents
General chemicals, originally referring to inorganic chemical products used in water treatment, such as Al2(SO4)3, etc.
Specialty chemicals, including activated carbon, ion exchange resins and organic polymers, flocculants, etc.
Formulation chemicals, including corrosion inhibitors, scale inhibitors, bactericides, combustion aids, etc.
Water treatment chemicals have strong specificity. According to the purpose of application, water treatment chemicals can be divided into two categories.
Purified water. PH value regulator, redox agent, adsorbent, activated carbon and ion exchange resin, coagulant and flocculant, etc.
Special industrial purpose. Corrosion inhibitor, scale inhibitor and dispersant, bactericidal and algaecide, softener, etc.
Compound water treatment agent is the main application form, which has the advantages of multi-function and convenient application.
Market distribution of water treatment agents
Worldwide sales of water treatment agents in 1992 were 2.837 billion U.S. dollars (excluding activated carbon, ion exchange resins, combustion additives and general inorganic coagulants), of which the United States was 1.479 billion U.S. dollars, Western Europe was 483 million U.S. dollars, and Japan was 575 million U.S. dollars. According to statistics, there are more than 500 companies engaged in the production and service of water treatment agents in the United States, and they focus on technical services. The Western European water treatment market is mainly controlled by American companies, and there are only a few water treatment companies in Western European countries. Western European organic polymer flocculants, especially polyacrylamide products, have certain advantages. In addition to the insufficient production capacity of American powder products, most of their markets are occupied by Western European companies. In addition, several Western European companies have also taken Korea from Japanese manufacturers. Fresh and some markets in the Middle East. There are also many companies engaged in water treatment agent production and technical services in Japan, including more than 20 companies related to cooling water treatment agent manufacturing and technical services.
