What are people who have monster rodi units with at least 800 gpd membranes using for booster pumps? I have done some looking but can't seem to find any.

Wow, I'm on city well with a TDS of 700. Wonder what my resin consumption is gonna look like. ooofYea my issue is I'm on a well and when I was running my 150gpd I would run the well dry and it would take me a week to fill the container. The other fun issue i have is the tds going into the ro unit is just about 400. With the new membranes I'm running and booster pump that doesn't like to run for more then an hour, gets the tds to 16 at best. So buy stock in di resin cause I go through a ton hahah
If going through a lot of resin it may be worth looking into replenishing it. I’ve never done it but it only takes some pretty common chemicals to recharge the resin.So buy stock in di resin cause I go through a ton hahah
I admittedly don’t know anything about commercial sized membranes but just from a quick google search you may be right. The first 800gpd membrane that I found states a 2.5:1 concentrate to permeate ratio, which is indeed better than “normal” sized membranes.My thought was more gpd = less water wasted or at least that was my thought process ... could be entirely wrong. I also never new or thought to look to see if di resin could be recharged I will have to look into that for sure
I still have it. It's a Cirqua system. I think they be out of business now... I'm not sure. I get my parts from Buckeye. It does about 40gph or almost 1000gpd. The pump is from GE Industrial and it's serious over kill. I have a 40g RO/DI tank and a 180g cistern for reject water which I use for doing laundry. The small system above the big one is gone now. I kept it for several years until I knew the big one would be reliable. It's been running for me for 10 years now.@Ron Reefman has a commercial-type setup, or at least he used to.
