Reverse osmosis technology is the most advanced and most energy-saving and effective membrane separation technology today. Because the pore size of the reverse osmosis membrane is very small, it can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in the water (removal rate as high as 97-98%). The system has the advantages of good water quality, low energy consumption, no pollution, simple process and easy operation. CHIWATEC adopts professional RO membrane design software and CAD computer simulation software provided by HYDRANAUTICS of Japan and Dow Chemical Company of the United States to ensure that the design system is scientific and reasonable.

Reverse osmosis technology is usually used in sea water, brackish water, fresh water; water softening treatment, wastewater treatment, and purification, concentration, and separation in the food, pharmaceutical, and chemical industries. In addition, the application of reverse osmosis technology to pre-demineralization treatment has also achieved good results, which can reduce the load of ion exchange resin by more than 90%, and the amount of resin regeneration agent can also be reduced by 90%. Therefore, it not only saves costs, but also contributes to environmental protection.Reverse osmosis technology can also be used to remove particles, organic substances, and colloids in water, and has a good effect on reducing the pollution of ion exchange resins and prolonging the service life.

Reverse osmosis is currently the most widely used desalination technology in the preparation of high-purity water. Its separation object is organic matter with a range of ions and a molecular weight of several hundred in the solution. Reverse osmosis (RO), ultrafiltration (UF), microporous membrane filtration ( MF) and electrodialysis (EDI) technologies are both membrane separation technologies.

In the past 30 years, reverse osmosis, electrodialysis, ultrafiltration and membrane filtration have entered industrial applications and have developed rapidly. In the semiconductor, integrated circuit manufacturing process, food, and pharmaceutical industries, reverse osmosis is usually used as desalination in the preparation of high-purity water. Ultrafiltration is mostly used as the post-treatment of the water system, and membrane filtration is used for the pre-treatment and post-treatment of water treatment to filter particles and bacteria.
