Membrane Output Calculation

Membranes produce the rated gallons per day (GPD) at 60 psi (4.1 bars)
operating pressure, 77°F (25°C) operating temperature and 500 ppm total
dissolved solids.

Membrane output gallons per day (GPD) depends on operating pressure,
water temperature and the ppm TDS in the feed water.

Expected GPD = Rated GPD × PCF × TCF

PCF

is the pressure correction factor

TCF

is the temperature correction factor

Calculation of Pressure Correction Factor (PCF):

The output (GPD) from

the membrane is directly proportional to the applied pressure.

The membrane is rated to produce the rated GPD at 60 psi. For any
pressure other than 60 psi the output GPD is multipled by the PCF.

PCF = Line Pressure (in psi) ÷ 60

Calculation of Temperature Correction Factor (TCF):

The output (GPD)

also decreases with decrease in temperature. This is because water viscosity
increases with decrease in water temperature.
