HDR UP-flow Regeneration Cation (anion) Exchanger

Description:
this type is one of the advanced and applied exchangers at present. It changes the co-current regeneration into up-flow regeneration, and designed according to atmospheric press bed C.C.R. This design saves not only acid (alkali) material, but also saves air source.

If connecting cation (anion) exchanger with one stage mixed bed in series, the producing water quality can be SiO20.1mg/L, conductivity10Umho/cm. Such cleaned water can be widely used in Industry boiler, Electronic industry, medicine, paper making, Chemical industry and Oil fields. Another equipment of this type is Double-Layer atmospheric press bed C.C.R up-flow regeneration cation (anion) exchanger. It has double-layer filling, i.e. put Strong and Weak resins as rate 1:1.2 into same tank. Then both resins will have more exchange capacity and higher clean water quality. Regenerant consumption will then be reduced, cation-anion one stage mixed bed will have a producting water quality of SiO20.1mg/L, conductivity5Umho/cm.

WORKING PRINCIPLE

1.    Cation Exchanger
When Raw Water goes into H type Cation Exchanger with Cation Resin inside, there will be such chemical reactioin:
Fe3+ + 3HR  FeR + 3H+
Ca2+ + 2HR  CaR + 2H+
Mg2+ + 2HR  MgR + 2H+
Na+ + HR  Na + H+
After the above reaction, all kinds of cations (Fe3+, Ca2+, Mg2+, Na+ etc.) may be absorbed on the exchanging resin. And H+ from resin will go into water. Thus there is only H+ in water, and it will have reaction with all kinds of Anions in water to form acid.

2.    Anion exchanger
After Cation exchanged, acid quality water goes into Anion Exchanger with OH anion resin inside, there will be such chemical reaction:
H2SO4 + 2ROH  R2SO4 + 2H2O
H2CO3 + 2ROH  R2SO3 + 2H2O
HCL + 2ROH  RCL + H2O
After the above Cation-Anion exchanging, more than 99% salt in water may be removed.
