*Operating pressure less than 40 psi will require a booster pump:
less than 49 GPD use BPLF-MO-115(-230),
more than 49 GPD use BPHF-MO-115(-230).
*Operating pressure greater than 80 psi will require a pressure reducing valve.

TESTING THE QUALITY OF THE MEMBRANE
Membrane Output Calculation
Membranes produce the rated gallons per day (GPD) at 60 psi (4.1 bars) operat-
ing 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 membrane is directly proportional to the applied pressure.
Note: The membrane is rated to produce the rated GPD at 60 psi. For any pres-
sure other than 60 psi the output GPD is multipled by the PCF.
PCF = Line Pressure (in psi) ÷ 60
Calculation of Temperature Correction Factor (TCF):
also decreases with decrease in temperature. This is because water viscosity
increases with decrease in water temperature.
