Development And Application Of Reverse Osmosis Technology In Pure Water Production Process

- Apr 12, 2019-

1. Present situation of pure water preparation process and reverse osmosis technology 

In recent years, China's water treatment industry, especially the pure water preparation professional technology and equipment has made great progress, and thus promoted the development of food, pharmaceutical, chemical, electric power, domestic drinking and other fields, especially in recent years, reverse osmosis technology has been widely accepted by various industries. The main reason for the rapid development of the industry: the country's improvement of the industry water quality standards and improve the corresponding industries to improve the quality of water demand growth is faster, the market demand is more prosperous, foreign membrane products poured into the Chinese market, accelerated the maturity of domestic membrane technology, the rapid growth of the national economy, the strengthening of the purchasing power of enterprises ; The continuous expansion of the market and the decline of production costs to form a virtuous circle; At present, the application of reverse osmosis technology is developing rapidly, and the technology market is maturing gradually. 

2. Application of reverse osmosis technology in various industries In the domestic reverse osmosis process to produce pure water is the largest market is the power industry, the industry enjoys the national priority development policy, has a strong financial resources, the number and scale of its projects are comparable to other industries, so that it becomes the largest user of the water treatment industry, thermal power plant steam Boiler water treatment Reverse osmosis process has been widely accepted, And a large number of the use of domestic equipment, good prospects. In the pharmaceutical industry, the national Pharmacopoeia for large infusion and other provisions of the use of distillation, reverse osmosis technology in tablets, oral liquid and pre-distillation process water market has been considerable, in recent years brewing, beverages and other food industry using pure water blending process has become a trend, bottled, barrel drinking pure water production process has been a large number of first or two levels of reverse osmosis 

Compared with household pure water devices and barrel bottled aqueous production lines, the market space of the group's pure water machine is also very broad, and its development will provide more practical equipment for improving the drinking water environment of enterprises, institutions, schools and public places. 

3. Current status of purified water production equipment 

Pure water production equipment by a combination of a variety of process equipment, involving the basic materials, accessories and motors, pumps and other basic industrial products, its overall equipment level is also a microcosm of domestic product level, the industry's equipment is currently characterized as follows: 

3.1. The domestic and foreign high-tech products represented by reverse osmosis membrane, pressure shell and high pressure pump are widely used, and the competition in the market mainly occurs not only between foreign products, but also between domestic companies. 

3.2. Ultrafiltration, electrodialysis, fine filtration, microfiltration and other representative of the main domestic supporting equipment with its performance, quality and price advantages, stable occupation of the vast majority of the domestic market, which fully demonstrates China's long-term scientific and technological investment and the unremitting efforts of related enterprises in the development of national industrial process of great role. 

3.3. The overall quality and efficiency of the main equipment, such as reverse osmosis membranes, are generally improved. 

3.4. The phenomenon of paying attention to the main desalination equipment and neglecting the pretreatment is more common, which also greatly reduces the overall design and operation level of the equipment, and affects the investment benefit of the whole equipment. 

3.5. Domestic water treatment equipment manufacturers in the middle and low level equipment market competition is fierce. 

4. Some views on the development of pure water equipment in China 1) Vigorously foster domestic reverse osmosis membrane component production enterprises, so that China's membrane component production in the international market occupies a place. 

Attract international large reverse osmosis membrane production enterprises in the domestic construction plant, comprehensively promote the development of the industry. 2) pure water production and the development of the entire treatment industry to its supporting domestic small and medium-sized industries, commercial enterprises to provide a good business opportunities. 

Related enterprises should timely production or introduction of industry supporting high-level materials, accessories, in order to synchronize with the water treatment industry development. 3) Complete sets of equipment production enterprises should further improve the level of process design, improve the production and installation level of equipment, and then improve the efficiency of equipment investment, reduce energy consumption, improve the utilization rate of raw water. Enterprises with conditions should aim at the international advanced level and improve their international competitiveness in order to promote the development of the whole industry.
