The Series 1 curve demonstrates the effect temperature has on the
permeate flow of a 50 Gallon per Day (GPD) membrane .
The above curve was generated by varying the water temperature. 50 GPD is produced
at approximately 72 degrees F
(at a constant pressure of 50 PSIG, and constant TDS of 125PPM Sodium softened water)
