I have a small DI system that I route through a portable soft water tank to help "pre-condition" what's feeding the DI.
Back to the resin: Who recharges the rechargeable resin vs. replacing both. Anyone find a bulk supplier?
DI systems use either two tanks or one tank. Pre-treating a two-tank system will result in slightly lower quality, more alkaline water. Soft water feed to a single-tank system will help only if the resin will be regenerated. Soft water will not yield more water from either DI system. Use soft water with detergent for washing, and feed hard water into the DI system for rinsing.
Softeners use one type of resin that can be regenerated with salt. DI systems use two types of resin. One is regenerated with concentrated hydrochloric or sulfuric acid; the other is regenerated with a concentrated solution of sodium hydroxide (lye). Handling these chemicals is so dangerous I've never heard of anyone other than trained operators regenerating DI resins.
