following RO models:
If the RO membrane fits loosely, you will probably need to wrap a few layers of tape near one end to give it a tight fit. A loose fit of this membrane could result in a higher permeate TDS. Performance conditions are based on 500 ppm tap water, 50psi applied pressure, feed water temperature of 77 degrees Fahrenheit, feed water pH 2-11 and 15% recovery.
