With the continuous development of China's economy, people's living standards and living requirements have been constantly raised. In China, many water bodies have been seriously polluted due to various complicated reasons, people are no longer satisfied with the use of untreated water resources, untreated water contains many harmful substances, so the water treatment equipment was born. Water treatment equipment is through a variety of physical and chemical means, to remove some of the water production, life does not need harmful substances, this kind of water filtration purification equipment. Water treatment equipment can filter out bacteria, viruses, heavy metals, pesticides, organic matter, minerals and off-color smell in the water, is a pure water, without heating can be drunk. The amount of water it filters is very low-cost. The pure water produced has high quality and ideal sanitation index. With the constant development of market and demand, the market of water treatment equipment is becoming more and more mature, the current water treatment equipment can be divided into the following categories: 1, electronic water treatment equipment 2, self-cleaning water filter 3, electronic descaler 4, water softener 5, pure water machine 6, water purifier 7, reverse osmosis Equipment 8, EDI ultra-pure water equipment 9, ultra-filtration equipment 10, purified water equipment 11, hospital water treatment equipment. These water treatment equipment is now widely used in: 1, Power Industry Water: Textile Printing and dyeing, papermaking water, chemical reagent production with pure water. Skin care products production with pure water, shampoo production with pure water, hair dye production with pure water. Chemical Laboratory, physical laboratory, Biological Laboratory. 2, industrial coating water: electroplating, glass coating with high-purity water. Water used in beverage industry: pure water, mineral water production, pure water used in food and beverage production, water used in hotels and living quarters, pharmaceutical raw materials, intermediate products, biological agents, enzyme extraction, protein separation. 5. Public Water Treatment Systems: water treatment for daily life, filtration and disinfection for swimming pools, water for ornamental fish farming, water saving irrigation, desalination systems for desert brackish water, desalination systems for seawater, metal recycling for electroplating wastewater treatment, domestic sewage treatment and reuse, product cleaning water recycling treatment, Industrial wastewater treatment. Although since the reform and opening up, people's economy, living standards and living requirements have been rising, people's awareness of environmental protection and daily morality have not been able to keep pace with the improvement of living standards and the economy, so water pollution has not been completely removed, and water treatment equipment market has been expanding, far from saturation, we can expect the future development of water treatment equipment.
