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