High Desalination 2521 RO Membrane for Industrial & Commercial RO Water Purifier Treatment
Reverse osmosis technology can achieve high-efficiency separation of inorganic salts and water molecules, and is widely used in seawater desalination and water quality treatment. Among them, the precipitation and growth of microorganisms at the interface of reverse osmosis membrane is the biggest cause of membrane fouling. The development of a new type of reverse osmosis membrane with anti-biological fouling is the most effective means to combat membrane fouling. Therefore, this topic is based on The aggregation and growth process of microorganisms at the interface of the reverse osmosis membrane, a bifunctional anti-biofouling reverse osmosis membrane that can resist the adsorption of pollutants in the first stage and inhibit the growth and reproduction of microorganisms in the second stage at the same time is prepared. The "passive" antifouling mechanism and the "active" antifouling mechanism were discussed. In this study, polydopamine was coated on the surface of polyamide composite membrane (TFC) by oxidative polymerization, and was synthesized in situ on it by chelation and reduction. Nano-copper particles were used to prepare a surface-modified reverse osmosis membrane.
