Reverse osmosis membranes are organic membranes derived from polymers: cellulose derivatives and polyamides.
Other polymers with better resistance to oxidation, pH or temperature such as polyacrylonitrile, polysulfone, polycarbonates and polyvinylidene fluoride are increasingly used.
Thermo Scientific manufactures a whole range of water purification systems using various purification processes such as reverse osmosis, ion exchange resins, EDI...
