Reverse osmosis membrane is a simulation of biological semi-permeable membrane made of artificial semi-permeable membrane with certain characteristics, is the core component of reverse osmosis technology. The principle of reverse osmosis technology is higher than the osmotic pressure of the solution under the action of other substances can not pass through the semi-permeable membrane and will leave these substances and water to come.
The scope of application is mainly used for reverse osmosis pretreatment, drinking water treatment, water reuse and other fields.
Filtration of suspended solids, colloids, proteins, microorganisms and other molecular substances in the media solution.
Principle of operation
Reverse osmosis is in the concentrated solution side of the pressure greater than the osmotic pressure of the solution, forcing water molecules in the reverse direction (and natural osmosis in the opposite direction) through the semi-permeable membrane into the dilute solution process, due to the process of reverse osmosis, the solution side of the water molecules through the semi-permeable membrane flow to the dilute solution, while the vast majority of the solute (dissolved solids) can not be through the membrane to be retained. Therefore, the concentrated solution is further concentrated or dehydrated, and the dilute solution is diluted and purified or desalinated.

RO technology introduction : The principle of RO technology is that under the action of higher osmotic pressure than the solution, RO water equipment will leave these substances and water according to other substances can not pass through the semi-permeable membrane. Reverse osmosis, also known as reverse osmosis, is a membrane separation operation that uses the pressure difference as a driving force to separate the solvent from the solution. Pressure is applied to the material liquid on one side of the membrane. When the pressure exceeds its osmotic pressure, the solvent will reverse osmosis against the direction of natural osmosis. Thus the low pressure side of the membrane to get through the solvent, namely osmotic liquid; The high pressure side produces a concentrated solution, that is, a concentrated solution. For example ,if the seawater is treated with reverse dredging, fresh water is obtained on the low pressure side of the membrane and brine is obtained on the high pressure side. Advantages and Applications : RO Reverse osmosis equipment has been developed rapidly in the past 20 years due to its advantages of good water quality, low energy consumption, simple process and easy operation. The main application areas of reverse osmosis equipment include: 1. Flowers and aquaculture water: flower seedling and tissue culture; Fish xing buckwheat colonization, beautiful fish and so on. 2. Fine chemical water: cosmetics, detergent, biological engineering, genetic engineering, etc 3. Alcohol drink water: liquor, beer, wine, carbonated drinks, tea drinks, dairy products, etc 4. Electronics industry ultra-pure water: monocrystalline silicon semiconductor, integrated circuit block, liquid crystal display, etc 5. Pharmaceutical industry water: pharmaceutical preparations, infusion, extraction of natural substances, traditional Chinese medicine drinks, etc 6. Quality drinking water: community, hotels, airports, schools, hospitals, enterprises and institutions 7. Industrial production water: washing glass water, automobile, electroplating ultra-pure water, coating, paint, paint, boiler softening water, etc 8. Seawater brackish water desalination: making drinking water from islands, ships and saline-alkali areas 9. Water for textile and papermaking: water for printing and dyeing, water for jet loom, water for papermaking, etc 10. Water for food processing: cold drink food, canned food, livestock and meat processing, vegetable finishing, etc 11. Circulating cooling water: air conditioning, smelting, water cooled air conditioning 12 .Swimming pool water purification: indoor natatorium, outdoor elephant view pool, etc 13. Drinking water: purified water, mineral water, mountain spring water, bucket bottled water, etc.
