1 Feedwater suitability must be determined by a water analysis.
2 Free chlorine removed by pretreatment cartridge.
3 ±1.5 lph, feedwater at 25°C and 60 psig pressure.
4 Membrane performance is dependent on condition, pressure, recovery, water temperature and water composition. Listed membrane
performance for a new membrane is based on optimum operating conditions of 60 psig, 15% recovery, 25°C (77°F) feedwater tempera-
ture and feedwater composition of a maximum of 500 ppm NaCl at a pH of 6.0-6.5.
5 Membrane performance, flowrates and recovery information are nominal values. Variations in the feedwater temperature, pumps and
reject orifice may slightly alter these results.
