1500 ppm NaCl feed water solution @ 25°C (77°F), @ 4.5 bar (65 psig), 15%
recovery. Flow rate and recovery will decrease with lower water temperature and
pressure. We recommend the use of a hot water mixing valve before the RO system for
water cooler than 15°C (59°F). Feed water suitability must be determined by a water
analysis.
