Test Parameters:
550 TDS Filtered (5 Micron), De - Chlorinated, Softened City Feed Water, 35 psi (2.41 bar) Feed Pressure, 150 psi
(10.34 Bar), 100 psi (4.83 bar) Operating Pressure, 77 Degrees F (25 Degrees C), Recover as stated, 7.0 pH. Data taken after 30 minutes
of operation. Low temperatures and high TDS levels will significantly affect system
’ s production capabilities. Computer projections should
be run for individual applications which do not meet or exceed minimum and maximum operating limits.
