MEMBRANE PRODUCTION CALCULATION:

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 on previous page)
Expected GPD = 100 × 0.666 × 0.754 = 50.2 GPD ± 20%*
50.2 GPD would be the Actual Production Rate
*Membrane manufacturers state their flow ratings with a ± 20% variance.

TIPS FOR LONG MEMBRANE LIFE:

1. Replace the sediment filter at least once every 6 months. This will
prevent mem brane fouling due to silt or sediment depositing on the
membrane.
2. Replace the 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 and extends the life of the
RO Membrane.
