Reverse osmosis membrane washing Electronic industry ultrapure water produce. Phamaceutical,medicine water supply produce Soft and salt removal of boiler water supply Driking water produce 3. Application: Working pressure:with the rise of working pressure,desalinatin will increase a little. Water temperature:when water temperature raising,desalination will increase a little. Raw water concentration:with the raise of raw water consistency desalination will be decline. PH value:under acid conditon although the membrane is not easy to block,the desalination will be decline. Solubility gas:under its dissociation situation easy to permeate,such as CO,SO,O,CI,HS. Trend of hydrogen bond:as those organic contains strong hydrogen bond,the desalination rate is lower,such as water,ammonia and phenol.etc. Size of molecule:the desalination rate raised with average diameter of molecule. Ion degreeraised with the increase of ion degreee,second and third degree ion desalination rate higher than single degree ion. 2. Main factors affect desalination rate of reverse osmosis membrane: Reverse osmosis is a kind of semi-permeable membrane working under differential pressure and just the water can through it. Its working principle is hydrogen bond theory and selective adsortioncapillary flow theory.The general reverse osmosis membrane is low-tension composite membrane and ultra-low pressure composite membrane,its structure is screw roll-type membrane. Its advantages as follows:unit volume with large surface area,great steam distribute,compact structure,high desalination rate,good interception.Disadvantages are easy to block,hard to wash. So it is important to do pretreatment and washing. 1.
