1.5.2Permeate (Product Water) Flow Rate

Stated on the serial number label (assumes no permeate back pressure, 2000 mg/L TDS maximum feed concentration, and rated temperature).

To estimate permeate output with back pressure, use the formula below:

(Permeate Flow on Label) x [(Operating Pressure) - (Permeate Back Pressure)] Operating Pressure

Permeate Back Pressure:

Maximum: 80 psig (5.5 barg)

Permeate Outlet:

1-inch FNPT
