And then the reverse osmosis is that one kind of the film being able to take pressure as motive force by the aid of the skill choosing through nature film (permeate partly) separates a technology , the water molecule permeates a film unceasingly while what be added pressure enters aqueous solution osmotic pressure greater than in system, is in charge of by that product streams flows into a centre, and then in water foreign substance of one end outflow, if ion , organic , bacterium , virus etc., produce water holding an outflow , achieve separation purification purpose thereby on the side of water-entering being held back in the film, in dense water. The film reverse osmosis equipment is applied separates a technology , can dislodge water electrification ion , inorganic substance , colloid particle , bacterium and organic matter etc. effectively. Be high purity water preparation , bitter salt water desalination and the best equipment in waste water treatment handicraft. Be used for electron , medicine , food , be spun gently broadly, fields such as chemical industry , electric power generation.
