Development and application of reverse osmosis technology in pure water preparation process

   

1. Status of pure water preparation process and reverse osmosis technology

In recent years, China's water treatment industry, especially the pure water preparation professional process and equipment water has made great progress, which has promoted the development of food, pharmaceutical, chemical, electric power, drinking and drinking, especially in recent years, reverse osmosis process. Widely accepted by various industries.

The main reason for the rapid development of the industry: the improvement and improvement of the industry's water quality standards prompted the corresponding industries to increase the water quality requirements faster, the market demand is more prosperous; foreign film products flooded into the Chinese market, accelerating the maturity of domestic membrane technology The rapid growth of the national economy and the strengthening of purchasing power of enterprises have formed a virtuous cycle of continuous market expansion and lower production costs; the application of reverse osmosis process technology is developing rapidly and the technology market is maturing.

2. Application of reverse osmosis technology in various industries

The largest market for producing pure water by reverse osmosis process in China belongs to the power industry. The industry enjoys the national priority development policy and has strong financial resources. The number and scale of its projects are comparable to those of other industries, making it the largest user in the water treatment industry. The reverse osmosis process for steam water treatment of steam boilers in thermal power plants has been widely accepted, and domestically produced equipment is widely used, with good prospects. In the pharmaceutical industry, the National Pharmacopoeia adopts the distillation method for large infusions, and the reverse osmosis technology has been considerable in the process water for tablets, oral liquids and pre-distillation. In recent years, the pure water blending process has been adopted in the food industry such as brewing and beverages. In the trend, the first- or second-stage reverse osmosis technology has been widely used in the production process of bottled and barreled drinking pure water. Compared with household water purifiers and barrel water production lines, the Group's pure water machine market space 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. Status of pure water production equipment

The pure water production equipment is composed of a variety of process equipments. The basic materials, accessories and basic industrial products such as motors and pumps are involved. The 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. Domestic and foreign high-tech products represented by reverse osmosis membranes, pressure shells and high-pressure pumps are widely used. The competition in the market mainly occurs not only between foreign products, but also between domestic companies.

3. 2. The main domestic auxiliary equipment represented by ultrafiltration, electrodialysis, fine filtration, microfiltration, etc., steadily occupy most of the domestic market due to its performance, quality and price, which fully demonstrates China's long-term technology. Investing and related companies make unremitting efforts to play a huge role in the process of developing national industries.

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

3.4. It is common to pay attention to the main desalination equipment and neglect the pretreatment in domestic complete sets of equipment. This phenomenon also greatly reduces the overall design and operation level of the equipment and affects the investment efficiency of the whole equipment.

3.5. Domestic water treatment equipment manufacturers are highly competitive in the middle and low-end equipment market.

4. Views on the development of pure water equipment in China

1) Vigorously foster domestic production of reverse osmosis membrane module manufacturers, so that China's membrane module production has a place in the international market. Attracting international large-scale reverse osmosis membrane production enterprises to establish factories in China to promote the development of the industry.

2) The development of pure water production and the entire water treatment industry provides good business opportunities for domestic small and medium-sized industrial and commercial enterprises. Relevant enterprises should timely produce or introduce high-level materials and accessories that are matched with the industry in order to develop in parallel with the water treatment industry.

3) Complete equipment manufacturing enterprises should further improve the process design level, improve the production and installation level of equipment, and thus improve equipment investment efficiency, reduce energy consumption, and improve raw water utilization. Enterprises with conditions should aim at the international advanced level and improve their international competitiveness to drive the development of the whole industry.
