Product introduction

Ro film introduction
Reverse osmosis membrane is a small aperture treatment for filtration of impurities in water.
Reverse osmosis membrane sourced from the United States Aerospace Technical Studies in the 20th century, currently has been widely used in science research, medicine, food beverage and salt water. This film has a small nano pore size, which allows water molecules to pass through, while preventing inorganic salt, heavy metal ions, organic agents, colloids, household cleaning bacteria and virus, etc. V. T. Reverse osmosis membrane is the important technology for filtration of water, with a small aperture to 0,0001 Micron, which can prevent impurities such as bacteria, virus, heavy metal ions and organic molecular in water. This kind of membrane uses pressure control principle and only allows the water molecules to pass through, while retaining contaminants to produce high purity water. The RO membrane is widely used in areas such as household water filtration, public water supply system and industrial sewage treatment.

Reverse osmosis membrane component
The reverse osmosis membrane structure is quite accurate, and popular components include end caps in both ends, center tubes, O rings, reverse osmosis membrane and water separator/water production. These ingredients work together to let water under pressure can go through filter element to refine and finally create pure water. Reverse osmosis membrane is generally composed of three-layer structure: non-woven fabric, polysulfone coating, salt removing membrane. For some special membrane elements, the film surface is coated with a modified layer.

Reverse osmosis membrane feature
1. the reverse osmosis membrane separation process should be done under high pressure. So the technology process must be equipped with high pressure pump and reverse osmosis membrane separation process of high pressure pipe for low energy consumption and non-deformed. It can be done in normal temperature. So it can be better used to separate and concentrate of heat sensitive substances.
2. it can effectively remove ion, molecular, organic colloidal, water bacteria, suitable for better quality of salt water treatment.
3. it has higher salt filtration rate and water reuse rate.
4. the membrane separator is simple and convenient for automation.
5. during the separation process, it is easy to produce film pollution, so need to clean the membrane regularly.
6. To prevent Film pollution, coarse water should be processed certain first, after reaching different indexes, it will go into the reverse osmosis membrane separator.
Technical principle of

Reverse osmosis treatment unit, treatment principle is under the control of pressure, so that permate water from the reverse osmosis membrane pass through to retractable water, While the salt can't go through and a small amount of organic substances will be retained in concentrate liquid.
The technical principle of reverse osmosis membrane is mainly based on two basic physical processes: osmosis and reverse osmosis. During osmosis, due to the appearance of gradient concentration, natural water flows from low-concentration solution to high-concentration solution through semi-seepage solution to dilute high-concentration solution. And in the reverse osmosis process, by applying higher pressure than its osmosis pressure on one side of high concentration solution, reversible flow water molecules, flow from high-concentration solution to low-concentration solution, To achieve the purity.

RO membrane filtration function is very strong. When water flows through the membrane, most of the inorganic salt, the organic material is soluble in the water and bacteria, virus and other creatures can't pass through this membrane and are retained efficiently. And, because the diameter of the water molecules is smaller than the RO membrane aperture, they can pass smoothly, thereby reaching the purpose of separation and purity. This process is not related to chemical changes, no auxiliary product generating and is thus considered a safe and efficient water treatment.
The RO film's features also include electrolysis spraying ability to exceptionally reduce water hardness, and the elimination rate is usually more than 90%, very important for hard water areas. In addition, the membrane life is relatively long, can be used for years under precision maintenance, higher sex price.

In the application, the RO membrane is not only widely used for household and commercial water purification, but also used in many areas such as salt purification, recycling waste water and reuse. Its appearance greatly improved access to clean water, human safety and play an important role in improving global water shortage and ensuring safe water quality. With the development of material science and film technology, the reverse osmosis membrane performance is improved and its unique value will be displayed in many more areas in future.

Frequently Asked Questions

Q: What's RO membrane?
Re: reverse osmosis membrane is a very small aperture filter, able to separate water molecules from solution with high pressure, and prevent most soluble salts, bacteria, virus, and other impurities from going through.

Q: How does the RO membrane work?
Re: reverse osmosis membrane uses reverse osmosis and osmosis principle, when the pressure is higher than the natural osmosis pressure applied, water molecules will flow back through semi-Seeed films to separate pure water.

Q: What contaminants can be trimmed by RO membrane?
Re: Ro film can remove bacteria, virus, heavy metal ions, soluble salt, organic agents and some water-soluble chemicals.

Q: How long RO membrane should be replaced?
Re: different RO membrane replacement cycle depending on frequency of use and water quality condition, replacement is usually recommended every 2 to 5 years, specific to manufacturer's instructions and actual use it for identification.

Q: What is the filtration rate of RO membrane?
Re: Ro film usually has a salt filtration rate above 90%, which means it is effective in reducing hardness and salinity in the water.

Q: How do reverse osmosis membrane require water pressure?
Re: RO system usually requires a certain water pressure to normal operation, this pressure range usually varies from 40 to 60 psi (square pounds).

Q: How to wash and care RO membrane?
Re: Ro film cleaning and care regularly include steps like frequent washing, backwash and rinse chemical to eliminate dirt and grow bacteria on the film surface.

Q: What is the application of RO membrane?
Re: the RO membrane is widely used in home and commercial drinking water purification, public water supply system, the use of water in medical and pharmaceutical industry, industrial filtration and sewage treatment, etc. V. T.
