PENTAIR GRO-36EN, 50EN, 75EN - 1:1 Ratio Super High Efficiency, Encapsulated Reverse Osmosis Membrane

If water efficiency is your concern with reverse osmosis process and saving as much water as possible is your goal, Pentair™ GRO-75EN (Also available in 36EN and 50EN GPD) Reverse Osmosis Encapsulated semi-permeable membrane is a high efficiency, 36-75 Gallons Per Day (GPD) reverse osmosis membrane that reduces water waste. Please note that modern RO systems are highly efficient.  Pentair Residential Membranes use an industry leading state-of-the art TLC (Thin Layer Composite) membrane providing high quality water for a broad range of water chemistries. Each membrane is required to meet factory's strict performance requirements prior to shipment. Encapsulated membranes already come with quick connect fittings on the housing. These membranes use less waste water with a near 1:1 ratio which means 1 gallon of RO water to 1 gallon of waste. Reverse Osmosis is the process by which water molecules are forced by your household water pressure through PENTAIR semi-permeable membrane.
