Demineralising plant (ion exchange resins)

Demineralisation on resin "HRW process"
While being based on the process of counter-current regeneration, BABCOCK WANSON has developed the "HRW" process which removes salts (and silica) by the provision of cationic and anionic resins (primary chain) and/or from mixed beds (final polishing).
The counter-current regeneration process presents many advantages in term of regenerating reagents consumption and quality of water produced :
- quality of the water produced with low conductivity and stable in time ;
- no suspension phase ;
- obtaining a water of constant quality over the duration of the cycle ;
- reduction in the volume of service water and thus in the volume of waste water ;
- reduction of the duration of regeneration and the quantity of reagents (-30 to 40%) ;
- reduction of the size of the installations.
