Deionisation Systems-Automatic Type
Deionisation is an ion-exchange process for removing ionic contaminants from a feedwater supply. The process passes feedwater through a cation-exchange resin bed followed by an anion exchange bed and, in the new TBR series, a final polisher stage to produce low conductivity water with low content of dissolved ionic species. The cation resin is in the hydrogen form and is regenerated on demand with hydrochloric acid. The anion resin is in the hydroxyl form and is regenerated on demand with sodium hydroxide.
