Recently, one of my employees changed his resin with the Xerio DI resin. It was not the virgin resin, but the regenerated resin. Anyway, he changed the resin in his 1/2 cubic foot tank about a week or 10 days ago, and today the reading was 44! I can’t believe it would go bad so quickly. Just yesterday it was reading 0.
Has this happened to anyone? Any ideas why? Thanks!
What were the last few jobs where he hooked up? We have seen filters go really quick hooking up to customers water bibs with old pipes hardly if ever used. We no longer hook up at the customers home to produce pure water… saves us a ton on DI and RO membranes compared to before.
It’s not just me then. It took my original resin a year and a half to go bad, though I didn’t use it often, but I do estimate 120+ of use. I ordered the washed resin and got 50-60 hours out of it, and I did check the tds at each source and it wasn’t out of the ordinary. The only source I didn’t check was three that I used at a high school, but I checked the first one at that same high school and it was running at 65 tds so I would think the others were similar. I only had the washed resin installed about 2 and a half months.
Interesting I’m visiting this thread again… I wonder if something was up with a batch of resin. We have a 4x40” DI cartridge and it went bad in just a couple mos. we usually get 6 mos out of a refill and process at the shop with a 4 stage set up. I think we will go back to Virgin resin
Might be a small thing but after use do you drain as much water from your system as you can? Thinking the standing water in there could be some of the culprit? I don’t get a ton of use on my WFP system as I do a mixture of Trad and WFP. I’m using the HydroPower DI unit and get a little over 4 months or so per bag of resin. I think if I used it real often I would go to RO/DI but this works for me now.
The resin may not he bad but you may have what’s known as “Channeling” where the sum of the water only flows toward one area or a channel is created causing a small amount of resin to handle all the impurities. You always want water to flow in and around all of the resin for maximum life. We used to see this is reclaiming gold…last thing you want is the metal in the solution to flow past the resin and not get picked up. A simple shake or roll of the tank can help.
