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.
