      The CSM Reverse Osmosis Membranes fits in a standard membrane housing for most conventional reverse osmosis systems. RANGE : 24 GALLONS PER DAY The same standard membrane housing can accommodate RO membranes with capacities ranging between 18-180 gallons per day (GPD). Specifications are based on 500 mg/L NaCl solution at 60 psi net pressure (4.1 bar), 77°F (25°C), 15% recovery after 24 hours. Individual element flux may vary ± 15%. There is a wide range of inorganic compounds that can be removed from drinking water with this reverse osmosis membrane. If you would like to change your membrane to a capacity other than what was originally in your Reverse Osmosis System, we recommend changing the drain flow control also. Flow restrictors help maintain the correct drainage for the membrane to prevent premature fouling/clogging of the membrane.
