Large Flow 600GPD Reverse Osmosis RO Membrane for Water Treatment Household Using
Reverse osmosis membranes can be used for a variety of fluid separations. Currently, the most widely used reverse osmosis membranes are cross-linked aromatic polyamide reverse osmosis membranes. Usually, m-phenylenediamine and trimesoyl chloride are used for interfacial polycondensation on the surface of porous polysulfone supported membranes. A polyamide layer is formed. The polyamide layer obtained by the reaction is the key to influence the water permeability and salt retardation rate. Therefore, focusing on the interfacial polycondensation reaction and optimizing the polyamide layer in order to obtain a reverse osmosis membrane with large flux and high salt removal rate has always been the direction of many researchers.

With the rapid development of reverse osmosis membrane technology and the in-depth use of membrane elements, the development and preparation of large-flux reverse osmosis membranes has gradually become the focus of research. Large throughput means that the energy consumption required to process the same volume of liquid is low, which can effectively save investment and equipment operating costs, and improve processing efficiency.
