RO/DI supplies
Just came across this site and thought I'd share since it was on topic with tonight's meeting:

Enjoy!

I'm thinking about adding DI to my RO unit. Is there any drawback to using the "color changing" DI resin? Sounds like a very small amount of dye may get into the water, but is it significant?
Why do they call resin "nuclear grade"?

"Color changing" DI resin is more expensive than the resin without the color changing capability. If you have a TDS Meter, which I'd recommend using, then using the "color changing" resin would be somewhat redundant.
I used to use the Tap Water Purfier and never saw any dye get into the water. It's chemically bonded to the beads in the resin.

Nuclear Grade means a very high quality. When I was in nuclear power, it was really really important to have very pure water. The DI Ion Exchanger was filled with Nuclear Grade water and there is nothing in the water.
You need pure water for Primary coolant since any impurities can lead to activation, hence a radiation or contamination issues.

Sweet. I'm gonna start calling everything that I think is really good stuff "nuclear quality." As in "Man, that tank in the front of the store at Aquarium Showcase was nuclear quality!"

Just FYI for those who don't want to pay extra for "color changing" type DI resin, the link at the top of the page here goes to a site that charges the same for both.

Ah. Thanks. Yep, I have a TDS, but like all my testing nowadays, I'm not real good about testing the water regularly. Just whenever I feel like maybe it "has been a while".

Yah, when I got out and went to college studying environmental science the topic of ocean dumping came up. I mentioned the "25 mile rule" and doing small primary water discharges prior to entering port. seems that we were not supposed to do that by the ocean dumping treaty. I also recall a time on board when someone reviewing the logs realized we were making potable water at the same time we were doing a primary discharge overboard. The good old days.

The dye in color changing resin is detectable in parts per billion in the water - is that significant? Well, people have been using color-changing resin for years and years...
