Demineralizers (Ion Exchanger)

In many applications is necessary high quality process water (demineralized water). Ion exchanger process is used for a long time for demineralization of the solution.  
 
Process Description
In ion exchanger process both cations and ions in raw water can be removed by treatment with an hydrogen-form cation exchange resin and a hydroxide form anion exchange resin in series.
 
Generally, demi plant consists of two cation exchanger column, one degasser and two anion exchanger column.
In cation exchanger column removed all cations; 
 
2 R-H + Ca+2 ―> 2 R2-Ca+2+ H+            Service (Cation)
 
In anion exchanger column removed all anions;   
 
2 R-OH + SO4-2 ―> 2 R2-SO4-2+ OH-     Service (Anion)
 
enki design demineralization systems according to custom requirement and specific application.
