- Removes dissolved inorganics effectively, allowing resistivity above 5 Ω•cm @ 25° to be reached (which corresponds to a total ionic contamination level in water of approximately 50 ppb).
- Environment-friendly:
- no chemical regeneration
- no chemical disposal
- no resin disposal
- Inexpensive to operate.
- Safe: no heating element.
- Removes only a limited number of charged organics.
- Requires feed by good quality water (for instance, reverse osmosis-treated water) for economically efficient operation.
