Performance
Notes:
Maximum production based
on a feed water of 77°F, SDI
< 1, 1000 ppm TDS, and pH
7. Individual membrane pro-
ductivity may vary (± 15%).
May be operated on other
feed waters with reduced
capacity. Percent rejection is
based on membrane manu-
facturer’s specifications;
overall system percent rejec-
tion may be less.
