Single RO, applies for water with a coductance less than 500μS/cm, water conductance of 1-10μS/cm.   Raw water through per-treating, fiter, then delivered to RO facility by high pressure pump to be water product is called Single RO.RO facility apply to water treatment facilities in food, beverage, chemical, hospital, electrical fields and can be as critical facilities in community, industrial park, oil field and etc. RO is one of the most advanced and effective separating technics in the world. By the penetrating principle of semi-permeable membrane, under some forc opposite to the naturally penetrating force, water of the solution with high concentration under the pressure is called RO. the RO is composed of RO components,and the diameter of the RO membrane is so small that cn wipe off the dissolved salt, collid, microbes, organic substance (efficiency of 97%-98%).the system is of high quality, low energy consuming, no pollution,simple technics, convenient operation.
