Pure Water Machine

  (h) Work pressure:desalination rate higher a little after the work pressure higher

  (g) Water temperature:desalination rate will higher after the water temperature higher(due to the reduce of water viscosity).

  (f) Density of resource water:desalination rate will lower after the higher of resource water density.

  (e) PH value:under acidic condition,although the membrane not easy to block,the desalination rate will be reduced.

  (d) Soluble air:easy to penetrate in its free state,such as CO,SO,O,CI,and HS

  (c) Hydrogen trend: for the strong hydrogen containing compounds,desalination rate is low enough,such as water,ammonia and phenol.

  (b) Size of molecular: desalination rate higher with the average diameter of molecular.

  (a) Ionic order:higher with the increase of ionic order,second- and third-order ion desalination rate should be higher than the single-order ion.

2 Main factors affect the desalination rate of reverse osmosis membrane:

Reverse osmosis is a kind of semi-permeable membrane under the impetus of differencial pressure,only allow water through it while the solute intercepted.it work pinciple follow the bond and selective adsortion theory. General reverse osmosis membrane is low pressure composite membrane and ultra-low pressure composite membrane,its frame is spiral-type membrane. Add a layer of porous support material bag-shaped reverse osmosis membrane in the middle. In the middle of membrane add a concentrated water donductivity net. The open side of donductivity net and bag-shaped membrane fixed on porous fresh water central pipe,and set the central pipe as a axis roll into a spiral type. outer shape is sealed of epoxy resin. The advantage is unit membrane with a great surface,good flow distribution,compact conformation,high desalination rate and good interception. Disadvantage is easy block,and difficult cleaning. So it is important to clean and pre-processing water treatment.
