3313-800GPD Anti-Pollution Water Purifier RO Membrane for Water Treatment
The invention relates to an anti-pollution composite reverse osmosis membrane and a preparation method thereof. According to the invention, an epoxy group at the terminal of PEG is utilized to react with the residual free amino on the surface of a polyamide composite layer, and a firm beta-site hydroxyl-amino bond is formed, so that a short chain poly-amino ethylene glycol unit is formed on the membrane surface, and the hydrophilcity of the membrane surface is improved. Meanwhile, the anti-pollution composite reverse osmosis membrane has a certain effect of blocking adsorption and deposition of pollutants on the membrane surface, so that the pollution resistance of the reverse osmosis membrane is improved. The preparation method disclosed by the invention is simple.
Performance

This product is suitable for areas where there is strict pretreatment, but the feed water still contains pollutants such as organic matter. The new anti-pollution membrane has excellent anti-pollution ability and cleanability. Because its membrane is electrically neutral, it greatly reduces the adsorption of bacteria and microorganisms on the membrane surface; the widest water supply channel not only has strong anti-pollution performance, but also has effective recovery after chemical cleaning. It is widely used in the regeneration and utilization of urban sewage and industrial wastewater, as well as the desalination of micro-polluted surface water, and the reuse of cooling and circulating sewage.
