Ultra-Low Pressure Reverse Osmosis RO Membrane for Industrial RO Water Purifier
Ultra-low pressure reverse osmosis membrane has the characteristics of high desalination rate, large water flux, strong anti-pollution, anti-bacterial erosion, etc. Due to its special surface structure, the surface potential is neutral and the hydrophilicity is good. The osmotic membrane is easy to adsorb surface active substances and is blocked by dirt, so it is a new type of reverse osmosis membrane used in various wastewater treatment.We provide the most widely used RO technology in the world — trusted globally by municipalities , industries , manufacturers, commercial markets, and families wanting clean, healthy water at home.
Compared with cellulose acetate membrane, low-pressure composite membrane and ultra-low pressure composite membrane have larger specific surface area, low operating pressure, large water production, high desalination and desiliconization rate, saving the operating cost and equipment investment of the system. All the advantages of composite membranes. With good chemical stability, low pressure composite membrane and ultra-low pressure composite membrane are ideal reverse osmosis membranes for preparing high-purity water today. Compared with conventional RO membranes, LF10 membrane has the same high salt rejection and high water flux at low pressure. In addition, , Due to its neutral surface potential and relatively hydrophilic, it has strong anti-pollution ability, so it has superior performance in the treatment of wastewater containing surface active substances that cause membrane fouling.
