2540-LP Reverse Osmosis System RO Membrane for Water Treatment Plant
The reverse osmosis membrane is the core component of the seawater desalination project, and its performance is directly related to the desalination project's desalination rate, water production, cost and energy consumption and other important performance indicators. The microscopic characteristics of the reverse osmosis membrane (surface functional groups, surface Potential, surface morphology, roughness, degree of cross-linking, thickness of separation layer and hydrophilicity, etc.) have an important influence on its macroscopic properties such as salt rejection rate and water flux. Incomplete, the detection methods of many indicators are not unified, some detection methods need to be further improved, and even some indicators have not yet formed corresponding detection methods. By testing the desalination rate, membrane flux and pollution resistance of these three membranes It is found that increasing the thickness of the separation layer, the degree of crosslinking and the density of the separation layer contribute to the improvement of the salt rejection rate of the reverse osmosis membrane. However, these factors will also reduce the membrane flux. The hydrophilicity of the polymer modified layer The groups and rough surface play an important role in improving the hydrophilicity of reverse osmosis membranes. In addition, the fouling resistance of reverse osmosis membranes can be improved by enhancing the cross-linking degree and the density of the separation layer or reducing the surface roughness and increasing the zeta potential. method has been enhanced.
