Two Column Deionizer
This type of deionizer is designed with two media tanks in series. The first tank contains cation resins in the Hydrogen (H) and the second tank contains anion resin in the Hydroxyl (OH). Typical processed water product is in the range of 50,000-250,000ohm resistivity depending on feed water chemistry and 1,000,000 to 2,500,000 ohm resistivity with Reverse Osmosis water as feed.
