Is 20,000 GPD the right size?
Size an RO system to your peak daily water use: the reservoir and batch-tank volume you mix each day, plus irrigation that runs on straight RO water. Leave headroom, because output drops with colder feed water and higher TDS.
Send us a recent water test and your daily water use, and we'll confirm the model and the pretreatment for your source.

Common questions
How much water does the ROS20 make?
ANGEL rates it at 20,000 gallons per day, which is 833 gallons an hour or 14 gallons a minute. Actual output depends on feed water temperature, pressure and TDS.
How much goes to drain?
ANGEL rates the system at up to 85%+ recovery (5:1) on suitable feed water. At full rated output that is roughly 4,000 gallons of concentrate a day.
What does the site need?
Three-phase 240V, 60 Hz power, feed water at 15–58 psi, a NPT 1.5" feed connection and a drain for the concentrate. The skid measures 96.5" L × 42" W × 80" H and weighs 1,650 lb.
How is it different from the ROS15?
The ROS20 and ROS15 share the same pump, pretreatment and automation. The difference is the membrane array: 12 membranes on the ROS20.
