General Specifications
1
500 ppm NaCl feedwater solution @ 25°C
(77°F), @ 4.5 bar (65 psig), 15% recovery.
Flow rate and recovery will decrease with
lower water temperature and pressure.
Barnstead recommends the use of a hot
water mixing valve before the RO system for
water cooler than 15°C (59°F).
