The reverse osmosis device is an equipment to purify the saline water with the action of pressure difference of semi-permeable membrane It is called reverse osmosis, as it is counter to natural penetration direction.Different materials have different osmotic pressure. The reverse osmosis method which is larger than osmotic pressures is used to obtain the purpose to separate, extract, purfy and condense.
More than 97% soluble salts and 99% glues, microbe, particulate and organic substances etc. can be removed with the reverse osmosis. It becomes the most ideal equipment for the modern program of pure water, hyper pure water and sirspace water. The remarkable characteristics of the equipment are shown as lower energy consumotion, no pollution, simple technics, high water quality, easy operation and maintenance.
