What is Ro membrane?
 
Reverse Osmosis Reverse osmosis membrane to achieve the core element is an artificial semipermeable membrane having a semipermeable membrane made ??of the characteristics of the biological analog . General use of polymer materials. Such as cellulose acetate film , an aromatic polyamide film hydrazide , an aromatic polyamide film . Surface pore diameter is generally between 0.5 ~ 10nm, the size of the membrane through its chemical structure. Some polymer materials and good salt rejection , the water permeation rate is not good. The chemical structure of some polymeric materials with more hydrophilic groups , and thus relatively fast through the water . So one kind of satisfaction should have proper reverse osmosis membrane permeation or desalination .
The reverse osmosis membrane should have the following characteristics: ( a ) having a high flow rate to be high rejection rate ; ( 2 ) having a high mechanical strength and service life ; ( 3 ) can function at a lower operating pressure ; ( 4 ) can be withstand the impact of chemical or biochemical effects ; small ( 5 ) by pH, temperature and other factors ; ( 6 ) the source of the film material is easy , simple processing, and low cost.
The structure of the reverse osmosis membrane , an asymmetric membrane and homogeneous film types. Membrane materials currently used primarily for the aromatic polyamides and cellulose acetate . Its components are hollow fiber , roll , frame and tube . Can be used for separation, concentration , purification and other chemical unit operations , mainly for pure water and water treatment industries.Reverse Osmosis Reverse osmosis membrane to achieve the core element is an artificial semipermeable membrane having a semipermeable membrane made ??of the characteristics of the biological analog .
