Water treatment equipment electrodialysis, electrodialysis device ① migration of ions of the same name, the ion exchange membrane selective permeability often not be one hundred percent and therefore there will always be a small amount of counter ion-exchange membrane through; ② ion concentration diffusion, Since desalination chambers and concentrating compartments was concentration difference exists, there is always a small amount of diffusion of ions from the concentrating compartments migrate to desalination chamber, thereby reducing the efficiency of dialysis; ③ water infiltration, although a solvent is not allowed to exchange membrane permeable molecule before, but due to the concentration difference between the desalination chamber and concentrate chamber, it will make part of the solvent molecules (water) to the concentrate compartment penetration; ④ water electrodialysis, since hydration and ion electric double layer formed in DC Under field, the water molecules can migrate from desalination chamber to the concentrating compartment; polarization ionization ⑤ water, sometimes due to poor working conditions, will be forced to water and electricity from hydrogen ions and hydroxide ions, they can enter the concentrate through the exchange membrane room; ⑥ water pressure infiltration, due to the difference in fluid pressure between the concentrating compartments and desalination chambers, forcing water molecules penetrate from the pressure side to the pressure side. Obviously, these secondary electrodialysis process is unfavorable factors, but they can be avoided or controlled by varying operating conditions. Water Treatment Equipment Co., Ltd.
