2021-01-04

 

The development of China's water treatment agents is developed with the introduction of modern water treatment technology. The development time is about 30 years later than the developed countries, but the development speed is fast. It has formed a system of independent research and development, industrialization.

Water treatment chemicals are mainly used in municipal water treatment, electric power, oil and gas, metallurgy, chemical industry, food and beverage, paper making, desalination, and other fields. Electric power, oil, and gas, metallurgy, the chemical industry is an important pillar industry in the national economy, and its corresponding water treatment agent market stability is high. High industrial demand, strict environmental protection requirements to promote China's water treatment agent industry's development.

 

1、The specific classification of China's water treatment chemicals industry

Water treatment refers to the need to deal with the water quality, the use of different water treatment supply and demand and chemicals so that water quality meets the production, life, and environmental requirements of the whole process. The application areas can be divided into industrial water treatment and domestic water treatment. Water treatment methods are mainly physical, chemical, and biological methods.

The water treatment chemical method refers to chemical agents used to eliminate and prevent scale, corrosion, the reproduction of bacteria and algae, and water purification treatment technology. Chemical water treatment technology is currently recognized at home and abroad as the most common and effective means of industrial water conservation.

According to the production technology classification, there are two main types of water treatment chemicals in China: one is a chemical with a clear molecular structure and compound name. This product belongs to the fine chemicals, generally known as single-agent products; second is the water treatment chemicals compound prescription products, this product does not have a clear molecular structure and compound name, generally to its use, performance characteristics (often crowned by the brand) named, such as corrosion inhibitors, scale inhibitors, biocides, flocculants. Scale inhibitors, biocides, flocculants, pre-film agents, etc.

According to the classification of its mechanism of action, the main varieties of water treatment chemicals are flocculants, corrosion inhibitors, scale inhibitors, dispersion agents, algaecides, and other auxiliary agents.

2Water treatment chemicals industry has a wide range of applications

The application areas of water treatment chemicals are generally divided into industrial water treatment, municipal/drinking water treatment, sewage/wastewater treatment, and desalination according to the end customer's water treatment objects and methods.

Industrial water

Water treatment chemicals are mainly used in circulating water cooling systems and industrial boiler water. Circulating cooling water is cooled by cooling towers and then cooled again, and the whole water system is in the dynamic process of circulation and used many times.

The circulating water cooling system needs to solve the combination of pipes and equipment, corrosion, and microorganisms. The main agents used in industrial circulating water treatment are scale inhibitors, corrosion inhibitors, algaecides, detergents, pre-film agents, etc.

The common methods of industrial boiler water treatment are water treatment outside the pot and water treatment inside the pot, and the agents used are mainly corrosion and scale inhibitors, deaerators, water supply alkali reduction agents, ion exchange agents, regeneration agents, softeners, alkalinity regulators, scale removers, etc.

Municipal/drinking water treatment

In producing qualified domestic water, appropriate water treatment chemicals must be used to make the ex-factory water quality meet national standards. The key links that should be treated are algae control, reduction of toxic or odorous algae agglomeration process in reservoirs, removal of floating and colloidal solids such as clay softening process, removal of calcium and magnesium salts, especially carbonate and bicarbonate corrosion control, used to reduce corrosion of distribution pipes.

Water treatment chemicals related to municipal/drinking water treatment are generally algaecides, coagulants, corrosion inhibitors, etc.

Sewage/wastewater treatment

If sewage/wastewater is discharged directly into the natural environment, these pollutants can disrupt the ecosystem and life cycle. Removal of all pollutants from wastewater is combined with several individual wastewater treatment methods to achieve hierarchical purification and gradual filtration until the water's pollutants are completely removed.

Water treatment chemicals involved in wastewater treatment are generally flocculants, sludge dewatering agents, defoamers, polymerizers, decolorizers, etc.

Desalination of seawater

The development of seawater desalination started in the 1960s, and after the development in recent decades, seawater desalination technology is relatively mature. Among them, the distillation method and membrane method have become a mainstream technology.

Membrane method needs to add scale retardant, detergent, coagulant, scale inhibitor dispersant and other agents in water, to reduce the impact of scale deposition on reverse osmosis membrane, distillation method is easy to produce fouling, reduce evaporation efficiency, reduce the impact through seawater pretreatment, add polyphosphate, organic phosphoric acid, phosphine polycarboxylic acid and other water quality softening in raw water, calcium, magnesium ions, and other metal ions

3, China's water treatment agents have formed independent development and industrialization system

The development of China's water treatment agent is developed with the introduction of modern water treatment technology. The development time is about 30 years later than the developed countries, but the development speed is fast and has formed a system of independent research and development industrialization. The development history of China's water treatment agent can be divided into three stages

1974-1989, that is, the introduction of absorption and localization stage, the goal is to establish China's water treatment agent research and manufacturing system.

1990-2000 is the stage of innovative research and development and industrialization. The goal is to establish China's water treatment agent and technology system with independent intellectual property rights.

After 2001 is the industrialization stage, China has more than 100 kinds of water treatment products. Various water treatment agents from production to quality basically meet domestic demand, and some products are exported. Technically speaking, the production process and performance of some products have been on the international leading level.

4, China's water treatment chemicals industry is gradually increasing the concentration of fragmentation

China's water treatment agent industry production enterprises are scattered; more than 20 large enterprises, more than 200 small technical service type enterprises.

In recent years, with the strict environmental protection audit, there is no scale advantage. Environmental protection does not meet the standards of small and medium-sized water treatment agent production enterprises gradually exit the market, especially small and medium-sized water treatment agent production enterprises dense Jiangsu, Shandong, and other provinces, due to the need to upgrade the local industrial structure, small and medium-sized water treatment agent enterprises to exit faster. In the case of steadily increasing market demand, market supply and demand showed a certain supply tension.

In this case, large enterprises' production capacity to technology, production scale, quality, and cost advantages to consolidate market position and expand market share.

 

5, strict environmental protection requirements to promote the development of China's water treatment agent industry

Water treatment agents are mainly used in municipal water treatment, electric power, oil and gas, metallurgy, chemical industry, food and beverage, paper making, desalination, and other fields. Electricity, oil and gas, metallurgy, and the chemical industry are important in the national economy; its corresponding water treatment agent market stability is high. High industrial demand, strict environmental protection requirements to promote the development of China's water treatment agent industry.
