1. Current status of pure water preparation and reverse osmosis technology　

　　In recent years, China's water treatment industry, especially the process and equipment for pure water preparation, has made significant progress, which has promoted the development of fields such as food, pharmaceuticals, chemicals, electricity, and drinking water. Especially in recent years, reverse osmosis technology has been widely accepted by various industries.

　　The main reason for the rapid development of this industry is that the improvement and enhancement of industry water quality standards by the government have led to a rapid increase in the demand for improving water quality in corresponding industries, resulting in a strong market demand; The influx of foreign membrane products into the Chinese market has accelerated the maturity of domestic membrane technology; The national economy is growing rapidly, and the purchasing power of enterprises is strengthening; The continuous expansion of the market and the decrease in production costs form a virtuous cycle; At present, the application of reverse osmosis technology is developing rapidly, and the technology market is becoming increasingly mature.  　

2. Application of reverse osmosis technology in various industries　　

     The large market for producing pure water using reverse osmosis technology in China belongs to the power industry, which enjoys the national priority development policy and has strong financial resources. The number and scale of its projects are incomparable to other industries, making it a major user in the water treatment industry. The reverse osmosis technology for steam boiler feedwater treatment in thermal power plants has been widely accepted and a large number of domestically produced equipment is used, with a promising future. In the pharmaceutical industry, the National Pharmacopoeia stipulates the use of distillation method for large infusion solutions, and reverse osmosis technology has been widely used in the process water market for tablets, oral liquids, and pre-treatment before distillation. In recent years, the use of pure water blending technology has become a trend in the food industry such as brewing and beverages. The production process of bottled and barreled drinking pure water has widely adopted first or second level reverse osmosis technology. Compared with household water purifiers and bottled water production lines, the market space for the group's water purifiers is also very broad. Its development will provide more practical equipment for improving the drinking water environment in enterprises, institutions, schools, and public places.

3. Current situation of pure water production equipment　

　　The pure water production equipment is composed of various process equipment combinations, involving many basic industrial products such as basic materials, accessories, motors, and water pumps. Its overall equipment level is also a microcosm of the domestic product level. The current characteristics of the equipment in this industry are as follows:

　　3.1. High tech products represented by reverse osmosis membranes, pressure shells, and high-pressure pumps are widely used both domestically and internationally, and market competition mainly occurs not only among foreign products but also among domestic companies.

　　3.2. The main domestically produced supporting equipment such as ultrafiltration, electrodialysis, precision filtration, and microfiltration, with their advantages in performance, quality, and price, have steadily occupied the vast majority of the domestic market. This fully demonstrates the enormous role of China's long-term scientific and technological investment and the unremitting efforts of related enterprises in the development of national industry.

　　3.3. The overall quality and efficiency of the main equipment such as reverse osmosis membranes in the complete set of equipment have generally improved.
