Okay, so I have a 4021 ro with double di setup in the garage. I'm producing lots of lovely pure but I've never achieved a ratio of 60/40. It seems I can only get about 80/20 or 70/30 at best.
I have a tap pressure of 40psi and a 95% rejection rate. I have a hf5 membrane which works best with a 80psi tap pressure, so I expect a below average rejection rate. I'm currently producing approximately 800ml of pure per minute or 48 litres per hour.
Does this sound about right for my current setup? I can't help thinking that my ratio should be better. Will my ratio improve along with the rejection rate with a booster pump? Scares me how much water is going down the drain!!
