So you're probably familiar with residential scale RO systems of 75, or 100 gallons per day, and you may have wished for faster RO water production. Here's a 1,500 gpd commercial RO system with a custom control system we recently installed in our local public aquarium. The system produces about 1 gallon per minute, and simultaneously feeds four 500 gallon storage tanks. RO water sent to each tank can be controlled with a selector switch. The system runs at only 80 psi to minimize energy consumption, and it runs at about 50% recovery (a 1:1 ratio of concentrate to permeate). She's a beauty!
