tiated by test data.
_1 fced water supply at 50 psi, 77°K and 750 TDS Quality water production, amount of waste
water and percent rejection all vary with changes in pressure, temperature and total dissolved solids.
tz: For water with hardness greater than 10 grains the use of a softener is recommended.
_:_ Efficiency rating means the percentage of the influent water to the system that is available to the user
as reverse osmosis treated water under operating conditions that approximate typical daily use.
_9 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 stor-
age tank or when the storage tank is bypassed.
