GE E4H-CE Series - Manual (Page 13)

1.4.1 Feed Water Specifications
The feed water requirements listed in Table 1.1 must be met to ensure quality per-
meate and extended membrane element life.
1.4.2 Permeate Flow Rate
Stated in Table 1.1 and on the machine serial number label (assumes no permeate
back pressure, 2000 mg/L Total Dissolved Solids (TDS) maximum feed concen-
tration, and rated temperature).
To estimate permeate output with back pressure, use the formula below.
Maximum permeate back pressure is 80 psig (5.5 bar).
(Specified Permeate) x [(Operating Pressure) - (Permeate Back pressure)]
(Operating Pressure)
1.4.3 Concentrate Flow Rate
Stated in Table 1.1 and factory-set as stated on the serial number label.
1.4.4 Pressure Range
The Pressure Ranges listed below (Table 2.1) are boost pressure:
Boost Pressure = [(Primary Pressure - (Post-Filter Pressure)].
