Introduction: In recent years, with the development trend of sewage treatment technology, ro membrane element has been widely used on ro membrane filter, and everyone has agreed. Ro membrane element has the advantages of uniform water flow, high environmental pollution, low replacement costs, simple external pipelines, and convenient cleaning and maintenance. It can also reasonably remove the residues of dissolved salts, colloidal solutions, pathogenic microorganisms in the water.
The ultra-thin separation layer is the effective layer that truly has a separation effect in the whole process of RO reverse osmosis and nanofiltration membranes, with a thickness of about 0.2μm.
(2). The increase in the number of stages also represents an increase in the total number of reverse osmosis membrane cartridge through which the flushing water flows. In order to better meet the total flow requirements, the working pressure of water seepage must be increased. It may exceed the specified value of the flushing working pressure, leading to an increase in the working pressure of the membrane surface and reducing the actual effect of flushing.
