Membrane Output Calculation Example
What is the expected GPD from a 100 GPD System at 40 psi pressure and
60°F water temperature?
PCF = 40 ÷ 60 = 0.666
TCF = 0.754 (from Table above)
Expected GPD = 100 × 0.666 × 0.754 = 50.2 GPD ± 15%
50.2 GPD would be the Actual Production Rate
TIPS FOR LONG MEMBRANE LIFE:
1. Replacement of sediment filter at least once every 6 months.This will
prevent mem brane fouling due to silt or sediment depositing on the
membrane.
2. Replacement of carbon block filter at least once every 6 months or
when chlorine breakthrough occurs. This will ensure good membrane
life and protect the membrane from chlorine damage.
3. Membrane should not be operated at lower than the minimum 2:1
concentrate to purified water ratio.
4. Operating reverse osmosis systems on softened feed water greatly
reduces the chances of membrane fouling.
5. Use the flush valve
after each use
of the system to extend membrane
life. It can be operated even when the system has been turned off. This
is especially useful in hard water conditions.
