DOW RO water purification  system/RO water purifier   Reverse Osmosis equipment  is a kind of reverse transfer movement; it is a kind separation method that separates the solute (impurity, organism, and brine etc.) and solvent (water) with the retention function of semi-permeable membrane and the propulsion of pressure. It can be classified into single-pass reverse osmosis and dual-pass reverse osmosis according to different quality of raw water that will be treated by Reverse Osmosis technology.   Single-pass Reverse Osmosis system: the water treated by RO system can be utilized directly. Dual-pass Reverse Osmosis namely the water produced by Single-pass Reverse Osmosis will be treated by RO Membrane again; therefore it is called Dual-pass Reverse Osmosis.   The RO equipment can be equipped with domestic famous brand components or imported components according to customers’ requirement. The equipped RO membranes are: Hydranautics, DOW, Toroy, Osmonics, Koch etc., of which the Salt Rejection rate are above 98%, max 99.7%. It can efficiently ensure the water quality. Reverse osmosis is widely applied in various of water production factories, pharmaceutical industry, brewage industry, beverage industry, food industry, industrial water, demineralization of brackish water etc..     Please contact us and tell us your details, including your needs, type of raw water, raw water quality analysis, we will provide you the most detailed and the most professional solution.If you have special requirements (such as the installation of equipment has specific requirements for area and volume) Please also tell us before we provide our design.All products are customizable, absolutely all the details to meet your requirements, product appearance and  accessories brand based on customer needs.Please subject to our final technique programe that sent you
