Feed water supply at 50 psi, 77°F, and 750 TDS - Quality water production and percent rejection all vary
with changes in pressure, temperature and total dissolved solids.
¢
Efficiency rating means the percentage of the influent water to the system that is available to the user as
revers osmosis treated water under operating conditions that approximate typical daily use.
¤
Recovery rating means the percentage of the influent water to the membrane portion of the system that is
available to the user as reverse osmosis treated water when the system is operated without a storage tank or
when the storage tank is bypassed.

TO USE THE CHART...
...Locate the intersecting point of feed
water hardness
and
pH
.
If this point falls within the shaded area, pretreatment* is
needed.
*Softening of the water is the suggested pretreatment.
This system conforms to NSF/ANSI 58 for the specific performance claims as verified and substantiated by
test data.
