3013-400GPD Reverse Osmosis RO Membrane for RO Water System
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.

Note:1. The Max. continous operation temperature is 35ºC when PH rate over 10.
2. In certain conditions,if would cause membrane breakage if the free chlorine or the other oxidant in feedwater.The production quality guarantee range is notincluded membrane breakage by oxiadation.
