Membranes are the principal component of the Industrial RO system. Membranes are made of spiral wound sheets of semi-permeable material designed to let pure water flow through, while keeping back all other impurities. Within industrial applications, the standard length of each membrane has been set to forty inches and in larger applications can go upto 80 inches. With a Pore size of about 0.0001 micron, this excludes most dissolved contaminants while allowing water molecules to pass through. 

Application Areas DOW RO Membrane Model -  BW30-4040-

These membranes are widely used in water filtration technology of Reverse Osmosis. With the use of pressure and force ( generally from a pumping system), the natural process of osmosis is reversed as feed water being is pushed through the semi-permeable membranes thus overcoming the natural process of osmosis , this ensures that the impurities are left behind and the filtered water flow out.
