I just joined to forum to ask this question.
I got a reverse osmosis system capable of producing 150 US Gallons of water a day. I connected it and left it running for over 2 hours, but the output TDS
were still quite high. I measure the TDS
in-line, input is 60 and output was 50. My pressure was only around 20psi, so I got a booster pump. With this my pressure is close to 40psi but my output TDS
is still only 35.
It's a D-D booster pump and I can't see a way to increase the output pressure on it.
Would a lower grade membrane work better with my low water pressure and produce higher quality water?
It's a 3 stage RO
system with a 5 micron pre-filter, a 10 micron block carbon filter and the membrane.
