The Pentair GRO-75EN features an industry leading Thin Layer Composite (TLC) membrane. This membrane is encapsulated which maximizes the life cycle of the cartridge inside. The flow rate for this membrane is 75 gallons per day (GPD), and is based on nominal performance. Most standard membranes have a 3:1 ratio which means for every 3 gallons of waste water that goes down the drain, you get 1 gallon of RO water. That ratio is only a 25% recovery of good water. What separates this membrane from the competition is the GRO-75EN features 50% recovery which is a 1:1 ratio! That means for every 1 gallon of waste water down the drain you get 1 gallon of RO water. No other membrane in the industry can make that claim!
