I'm getting zero right now but it's all new prefilters and new DI. The RO is outputting steady at around 7. Not the best membrane I ever owned, the one before this one had a much better rejection rate or whatever the term is, it was almost always zero except for the first half hour or so. My DI lasted much longer on that membrane .. until the membrane went that is. |
If it is a good and properly labled membrain ie. a Dow filmtec
TW30-1812-75 it is 75GPD @ 50 PSI. at 90 PSI it should give you about 130 GPD. the max operating PSI is 300PSI on the dows and I think you can get about 170GPD out of that one @ 100 PSI
these numbers are for 75 degree water temp, so you won't get that much as I doubt your tap water is 75 degrees. for example the 75gpd membrain only puts out 50gpd at 60 degree water.
