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. Contaminants are rinsed to the drain with a reverse osmosis water purifying system, while your high quality drinking water is stored in the holding tank ready for drinking on demand. There is no contamination of drinking water with impurities.

This membrane needs a flow restrictor to work properly
Filters and membrane elements are not to be installed on microbiologically unsafe water supplies. TLC Membranes are not certified to sanitize water, remove cysts, bacteria, or viruses. Filter and membrane element performance can be affected by fluctuations in water quality. Use sediment and carbon pre-filters with this membrane to avoid damaging the RO membrane.
DRAIN LINE FLOW CONTROL KITS In order for this membrane to provide 1:1 water ratio, you need a flow restrictor. Please choose a membrane with flow restrictor included from the dropdown above or if you need to buy in bulk, follow the link here flow restrictor.
