China RO Water Deionization Mixed Bed Ion Exchanger for Ultra Pure Water

RO Water Deionization Mixed Bed Ion Exchanger For Ultra Pure Water
Process Theory:
Mixed ion exchanger known as mixed bed.Mixed ion-exchange demineralization, is the cation and anion exchange resin in the same switch, in the run before the first they were then generated OH-and H-type, and then mixed. Therefore, the mixed bed can be seen by many cation resin ,anion resincomposition of the staggered and complex multi-stage bed.
In the mixed-bed operation, cation resin,anionresin is uniform with each other, so the cation and anion exchange reaction is almost the same time. Or, cation exchange and anion-exchange water is several times staggered, so the H ion exchange generated by the H and OH ion exchange generated by the OH-are not cumulative, but each other immediately neutralize and generate H2O, This makes the reaction was carried out very thorough, very good water quality. Mixed bed resin failure, the first separation of the two resins, and then regeneration and cleaning. Regeneration after washing, and then mixing the two resins, but also put into operation.
Application
Ion exchange technology in the field of water treatment is widely used. Such as water softening, desalination, high water extraction, industrial wastewater treatment, heavy metals and precious metals recovery and so on. Water softening process in the boiler so widely used.

Basic principles
Ion exchange method, can be ionized water was Cation, anion removed to sodium chloride (NaCl) on behalf of inorganic salts in water, water desalination in the basic reaction equation with the following expression can be:
1, cation exchange column (Cation): R-H + Na + → R-Na-H +
2, anion exchange column (anion bed): R-OH + Cl - → R-Cl + OH_
Yang, known as anion exchange column in series after the resumption of bed, the total response can be written as:
RH + ROH + NaCl ------- RNa + RCl + H2O
From this we can see that the NaCl in water were resin has H + and OH_ replaced by the reaction products only,
It reached the role of salt removal
3, mixed ion exchange column (mixed bed): mixed bed is positive, negative resin by a certain percentage (usually 1:2 for Cation, anion resin to exchange the end while at the same time renewable) made into mixed column, the actual on its portfolio into the water immediately generate H + and OH_ small degree of ionization of water molecules (H2O), almost no sun beds or shade beds Exchange is produced by the phenomenon of reverse exchange, it can exchange reaction was carried out very thoroughly, so mixed-bed effluent quality better than the sun, the composition of the complex anion bed bed in series can achieve the water quality, the system can take very high purity product water.
the advantages of Ion Exchange Chromatography:
It is a non-denaturing technique that can be used at all stages and scales of purification.
By changing pH, salt concentration and/or the ion exchange media, an IEX separation can be controlled in a predictable way.
It can serve as a concentrating step. A large volume of dilute sample can be applied to a media, and the adsorbed protein subsequently eluted in a smaller volume.
It offers high selectivity, in that it can resolve molecules with small differences in charge
