Detailed specification

Basic overview 
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. Users have full knowledge. 
The company's ion exchange equipment at the plexiglass cylinder and two steel cylinders, generally Yang-chu, Yin-chu, mixed column configuration. General filling of the resin with acid, base resin, type the 001X7 and 201X7. The remaining water requirements based on user needs or various other types of resins are available for selection. 
Basic principles 
Ion exchange method, can be ionized water was Yang, 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 yang, yin resin by a certain percentage (usually 1:2 for Yang, 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.

I. Introduction 
Ion exchange, water can be ionized impurities were removed, this process is through the ion exchanger (resin) for the ion exchange resin to exchange genes with a different activity, but also sun, overcast, strong and weak points of the generally with the acidic functional group, with cation exchange material as cation exchange resin, with a basic functional group, with the anion exchange material, said anion exchange resin. Use of resins with different characteristics of the exchange of genes, can be a water softener, salt, produce highly purified water and industrial wastewater treatment.
