Water treatment technology in China began in the 1950s, the introduction of chemical technology from the former Soviet Union have begun to use inorganic phosphate water treatment agent. 1970s the introduction of large chemical fertilizer unit at the same time the introduction of water treatment technology, the introduction of the United States Bates technology in the early 1980s, the introduction from the United States nalco phosphate water treatment technology and imported from Japan, Kurita-225 alkaline treatment formula.On this basis, China at the line developed a domestic water treatment technology and water treatment agents, wastewater treatment technology from the 1960s, a deal with most of the current secondary treatment, flocculant and coagulant had already begun in the 1950s production, but in the 1960s before being applied to industrial production, developed a number of novel agents in the 1980s. The production of organic flocculants in China polyacrylamide series, non-ionic and anionic species and cationic products. Which yield a larger, more varieties of plant of Guangzhou, South Africa and plastic plant.2000, a variety of water treatment agent in addition to individual species in the technical preparation of a breakthrough, has been producing the variety of applications still dominant. The average annual growth rate of the various species will be around 5% -6%.
Global water treatment chemicals market stability has increased
Water treatment chemicals also known as water treatment agent, stabilizer and water quality, mainly used for industrial water treatment chemicals, including cooling water, boiler water and scale inhibitor for oilfield water for industrial water treatment, corrosion inhibitors, dispersants, algicide sterilization, anti-foaming agent, flocculant, deoxidant, regulator and chelating agents such as sewage sludge.Coagulant and flocculant of raw water and sewage treatment, water treatment chemicals including water treatment chemicals, in addition to activated carbon and ion exchange resins are also important. According to statistics, more than 500 in the United States engaged in water treatment agent in the production and services company, their technical service. The water market in Western Europe by U.S. companies control only a few Western European countries the water treatment company. Japan engaged in the production of water treatment agents and technical services company, in which cooling water treatment agent manufacturing and technical services company, with more than 20.
Global water treatment specialty chemicals market sales in 2012 expected to be $ 11 billion, according to a rate of 3.1 percent, in 2010 estimated the total market sales of about $ 10 billion, of which the United States accounted for 37%, 16% in Western Europe, Japan accounted for 8% China accounted for 12%.
