· It is a most widely used product, and it is most effective when the concentration of the original water is below 10,000ppm.

· It can be used in varous ways since it has excellent performance and chemical durability.

· It is used in making drinking water, making industrial water, water for medical reason, wastewater treatment and concentrating food and drugs.

· Contamination of the membrane is the most problematic part when using reverse membrane.

· Especially, when using surface water and waste water as a basis water, high concentrations of organic matter often cause pollution that is difficult to recover.

· With stain resistance reverse membrane developed by Woongjin chemical's new technology highly reduced this problem. 

· Hydrophilicity has been improved, so hydrophobic substances (oil, organic matter.etc)  deposits less, and since the surface of the membrane is smooth, there is also less deposition of particles.

· Sea water contains high percentage of salt, varying from 3 ~ to 5% , depending on region. 

· Because of this , sufficient amount of sea water is hard to use as drinking water and industrial water.

· High performance of CSM overcomes this shortcomes. High tech sea water desalination membrane enavles to change sea water into drinkable water by just one step.

· Not only it lessens the salt, is also removes all harmful substances that might be included.

· Also, it costs less than any other method.

· It is most importand to highlight the importance of clean water at home, since it is directly linked to health.

· Reverse membrane propose the most certain method on unsure water quality.

· You can enjoy the most clean and pure water at home.

· The feature of nano membrane is that the removal ratio of  monovalent ion and divalent ion are different.

· According to this feature, it is available to remove selectively.

· As its main field of application, it recovers special chemicals or expensive raw materials such as developer and dye, and reduces the concentration of divalent ions in seawater desalination facilities

· It is also used for preprocessing to remove parts of monovalent ion.

· Ultrafiltration membrane cannot remove ion in the water, but it can remove fine particles.

· Usually, it can remove material of size less than 0.01 μm (one-thousandth of the thickness of the hair).

· For industrial use, it is used for manufactured ultra-pure polishing purposes and can also be used for residential use.
