Description
An RO DI water system first removes around 95–99% of dissolved salts with reverse osmosis, then polishes the water through mixed-bed deionization resin to bring conductivity close to zero. The result is high-purity water for laboratories, cosmetics, batteries, car detailing and other uses where RO water alone is not pure enough.
Running a DI resin bed on raw Omani water exhausts it in days. Putting RO in front means the resin only polishes what the membrane leaves, so an RO DI water system gives far lower running cost than DI alone.
Features of the RO DI water system
- Sediment and carbon pre-filters
- RO membrane stage – removes the bulk of dissolved solids
- Mixed-bed DI resin – polishes to very low conductivity
- Inline conductivity or TDS meter – shows when resin is exhausted
- Wall or frame mounted
- Three sizes – 50, 200 and 800 GPD
