Extra Low Pressure 4inch Industrial Reverse Osmosis RO Membrane for RO Water Purifier
Reverse osmosis (RO) is a method of separating the solute and solvent in the solution by means of the selective interception of the semi-permeable membrane under the pressure drive. Regardless of the low-pressure composite membrane or the ultra-low-pressure composite membrane, it is the size of the water permeation rate. , the desalination rate is used to measure the quality of the membrane, and the water permeation rate, that is, the water flux, is proportional to the driving pressure. If a certain water flux can be achieved, the lower the required driving pressure, the lower the Energy consumption, but also reduce equipment investment such as pumps, pressure vessels and pipes.
