Hey guys. I have to make 100 gallons of ro water a day. i really require the water within hours. i had 1 400gpd membrane hooked up to a booster pump at almost 100psi. this only output 7ml/s. so now then i tried 2 membranes parallel and was getting 14ml/s output. i needed more water so i opt to get a third membrane and for a couple of days it output 21 ml/s now im only getting 10ml/sec and im not very happy about this right now. please what is it going to take to get a steady 30ml/sec of water output from a ro system. i bought the biggest membranes i could get "400gpd" and they produce less than 100gpd at 100psi. I need something fast to get this water faster. I use alot of ro water and my demand for it is high. right now 1 of 3 of my filter is making 7ml/s while the other 2 are only make 1-2 ml/s. i have check valves on all the inputs/outputs of the membranes. my flow restrictor is adjustable and is about 1400ml/s. this is driving me CRAZY
