DI EXCHANGE TANKS
Exchange tanks are used in service deionization (SDI) systems to replace the synthetic resins that capture harmful cation and anions. They are not required for continuously-regenerating Electrodeionization (EDI) systems.
VARIABLES TO CONSIDER:
- Feed Water characteristics and outflow quality requirements
- Sizing — larger deionization tanks allow higher flow rates.
- Bed types — Separate bed tanks produce higher volumes at lower quality, mixed bed tanks produce lower volumes at higher qualities.
- Downstream of RO system for polishing purified water
- Standalone purification in place of an RO system in situations where an RO system can’t be used.
- Hospitals and Universities
- Food and Beverage
FREQUENTLY ASKED QUESTIONS (FAQ’s):
What is deionized water? Deionized water is water that has had all the dissolved minerals removed from it.
How many gallons will my DI exchange tanks produce? The total number of output gallons depends on the size and design of the DI exchange tanks, and the total dissolved solids in the source water. Contact us for help calculating based on your variables.
What are total dissolved solids? Total dissolved solids are the positive and negative charged mineral ions in feed water.
