(1) Membrane performance is dependant on membrane condition, pressure, recovery,
water temperature and water composition. Listed membrane performance for a new
membrane is based on optimal operating conditions of 200 psig, 10% recovery, 25°C
(77°F) feedwater temperature and feedwater composition of 1000 ppm NaCl at a pH of
6.0-6.5.
(2) pH range is for membrane only. Minimum pH for the ULTROpure unit is 6.0.
