• The reverse osmose technology relies on the pressure action more than osmotic pressure and completes the filtering by use of the capillary action of the membrane.
• The processing techniques of reverse osmose technology include 3 parts: pretreatment, membrane assembly connection techniques, and after-treatment.
• Pretreatment techniques: Intended to improve the quality of treated water, prevent the fomites in such water from any damages on the membrane, and prolong the service life of membrane, so as to cut down the operating costs.
• Assembly connection way: Usually divided to 1-level and multi-level connections.(Mainly)1-level&multisection is that the inflow liquid go through membrane separation after pressurizing at one go; and 2-level separation needs the membrane separation to be done after pressurizing twice.
• After-treatment techniques; Membrane-permeated water is alternatively termed as freshwater, i.e. the outflow water permeating from the reserve penetration membrane through pressurizing. Since it is not possible for the membrane to hold back all the inorganic matters, the permeated water is bound to contain some ions and gas such as Na+?HCO3-?co2 ETC. As a Result, if such water is to be prepared into highly purified water, it is then necessary to employ after-treatment such as ionic exchange and degassing tower.
• The reverse osmose method delivers a high desalination rate, low operating costs and is able to get rid of bacteria from cells, intracellular toxin and other organic matters. Thus it has been.
  Widely applied in desalination of seawater bitter salt water, preparation of the drinkable water for food-stuffs industry and purified water in pharmaceutical industry. To summarize, this method is especially suited to those trades that require both sterilization & getting rid of particles and desalination.
