1.5.2 Permeate Flow Rate
Stated in Table 1.1 above and on the machine serial number label (assumes no permeate
backpressure, 2000mg/L TDS maximum feed concentration, and rated temperature).
To estimate permeate output with backpressure, use the formula below:
Maximum permeate backpressure is 80 psig (5.5 bar).
