water treatment chemicals tend to develop towards high efficiency, low toxicity and pollution-free

December 13, 2001

the rapid development of modern society and industry and the severe situation of lack of water resources and intensified pollution have greatly promoted the continuous emergence of new varieties and new technologies of water treatment chemicals and the expansion of industrialization scale. The research and development of new water treatment chemicals is tending to be high-efficiency, low toxicity and pollution-free

first, in terms of corrosion and scale inhibitors. With the improvement of the recycling efficiency of industrial cooling water, the urgent needs of sewage recycling and the wide application of reverse osmosis membrane in seawater desalination put forward higher requirements for corrosion and scale inhibitors. People not only require that they can inhibit the corrosion of various metals in water with high salt content, but also require higher tolerance and dispersion of calcium carbonate, calcium phosphate, magnesium silicate, iron hydroxide and zinc hydroxide. At the same time, they also put forward higher requirements for their chemical stability. Among organic phosphonic acids, PBTC and HPA are the key varieties to continue to be developed,

at the same time, the industrialization process of new PAP with high correlation EMP, which is particularly effective for calcium carbonate, should be accelerated. In terms of polymers,

in addition to improving performance, another move is to develop environmentally friendly products. In addition, in order to realize the accurate and scientific management of dosing and implement analysis or rapid analysis, the research and application of polymer dispersants with tracer groups has become a hot spot in the field of water treatment

second, in terms of fungicides and algicides. In recent years, due to the limitation of chlorine, bromine compounds and chlorinated fungicides such as Cl

O2 have greater development space. At the same time, environment-friendly high-efficiency and low toxicity non oxidizing biocides

will also be welcomed by the market. In addition, with the increasing demand for sewage recycling and reuse in industrial cooling water, in view of the increasing demand for

reuse in industrial cooling water, and in view of the high salt content of reuse and COD and BOD, the development of agents with high

efficiency for sterilization and algae eradication, which are 30% lighter than steel, slime inhibitor and microbial dispersant will also become a hot spot

third, in terms of flocculants. Inorganic and organic polymer flocculants with high efficiency, low toxicity or non toxicity are gradually replacing

traditional flocculants. Nowadays, plastic recycling is becoming a major ecological problem. In recent years, with the aggravation of water pollution and the improvement of water quality standards, flocculants are required not only to have the function of highly efficient selection of equipment and not to be too casual descaling, but also to have the functions of removing COD, phosphorus and nitrogen, as well as sterilization and algae killing, oxidation and reduction. Therefore, non-toxic, high charge, high molecular weight cationic organic flocculants, natural high molecular flocculants, microbial

flocculants will be the focus and trend of industrial development in the future
