victoly Posted June 28, 2019 Share Posted June 28, 2019 Thought you guys might be interested in this:Its an RODI system that uses three 24V apex valves to control cutoff and membrane creep. Here's a process diagram:and here's what it looks like in real life: I haven't put it into full production yet (my tank is still dry), but im glad I finally got it working. I still need to determine how long to dump the RO and a few other details in code, but overall I'm happy with how it turned out. 2 Quote Link to comment Share on other sites More sharing options...
jolt Posted June 28, 2019 Share Posted June 28, 2019 Awww, links are broken. Are you gonna run mixed bed in both DI, or separate cation and anion? Quote Link to comment Share on other sites More sharing options...

victoly Posted June 28, 2019 Author Share Posted June 28, 2019 ehhhh, when i view it in browser they show up fine! when i tried in tapatalk they looked broken. I won't be running separate resins at this point. Maybe in the future. The economics aren't that great last time I ran the numbers. Quote Link to comment Share on other sites More sharing options...
jolt Posted June 28, 2019 Share Posted June 28, 2019 I see. Looking at the diagram it looks like there is no final TDS meter? Quote Link to comment Share on other sites More sharing options...
