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.
