1. To ensure peak performance, the permeate flow rate and stabilized salt rejection are meticulously determined under the following rigorously tested standard conditions:
NF membrane (2000ppm MgSO4, 0.48 MPa, 25ºC, 15% recovery), RO membrane (2000ppm NaCl solution,
1.55 MPa, 25ºC, 15% recovery) prior to any hot water disinfection.
2. Please be aware that the variation range of permeate flow is +/-15%, and additional fluctuations in the final water yield may arise due to
the heat treatment processes in place.
