DI resin is the small ‘beadlike’ substance that makes the entire water deionization process tick.
While creating highly purified water applicable for medical, bio or laboratory use, It catalyzes the ion exchange that rids the water of any non essential charged ion. Whenever dislodging either the hydrogen or hydroxyl ions, as water passes through the resin beads, all the other ions stick to the resin. Anyway, this process is known as Ion Exchange or Deionization.
As resin begins to age or become fouled from contaminants as well as improper regeneration, the ion exchange process loses its efficiency. Over time the resin beads can become fouled or damaged. While hindering the ion exchange process, Therefore if this happens, they lose their ability to hold hydrogen and hydroxyl ions. Fact, here’s the poser. A well-known fact that is. It’s impossible to handle throughout the batch regeneration process, if two or three of the 20 30 deionization canisters contain fouled resin that requires additional attention. The fouled resin should not get treated properly, and ultimately reduces the resin quality of the other ‘2030’ deionizers in the batch process.
That’s why Total Water never mixes resin.
Instead, we keep identical resin in every canister for the entire lifespan of the deionizer. We treat that resin appropriately or discard it without affecting the quality of the other resins, I’d say in case we identify any canisters with fouled resin. Furthermore, it was not difficult to recognize fouled or expired resin. Fact, each deionizer is equipped with some sort of water quality monitoring system -be it a digital meter or pretty straightforward water quality light system.
I know that the monitor’s light changes from greenish to light red, when the water quality drops below a certain resistance level. At that point, you can call a water treatment service to exchange your deionization tanks.
Another option is ‘off site’ monitoring, where a water treatment service will monitor your system for you. Although, if the water quality drops below a certain resistance set point, a ‘on site’ service can be arranged.
Ensure that it’s calibrated correctly each year, I’d say if you have a digital meter.
When actually, we’ve experienced customers who falsely believe their deionized water is meeting the necessary quality standards an incorrect calibration was misleading them. Of course, whenever ensuring your high purity DI ain’t expired or fouled is crucial, Given its importance in the deionization process. So, contact us to see if resin gonna be your issue, if your deionization system indicates any drop in water quality.
