I have a 75 gpd bulk reef supply RO system (5 stages prior to DI). I purchased the 150 GPD water saver upgrade (another DuPont 75 gpd RO filter that takes the waste from the first filter). Water pressure is 60 psi. I totally forgot to get a proper flow restrictor with the upgrade. It’s a 550 built in with a flush valve. The output prior to DI is still just a trickle without any appreciable flow rate increase since installing the upgrade.
The current flow restrictor is a 550 ml inline built into the back flush valve they BRS sells. I’d think I’d need an 800 ml restrictor for 150 gpd. If I use this setup, will I lose membrane efficiency since my pressures are marginal
I wonder if I am just wasting my efforts with this water saver system - I’m not sure how I can keep membrane efficiency with this kind of setup. I would seem a better idea to run two membranes completely in parallel with restrictors at each membranes waste, with a pre membrane boost pump to be able to get additional flow.
Or should I consider a pre boost pump with this my marginal water pressure?
Please help educate me. Thanks!
