1. For peak performance, the permeate flow rate and stabilized salt rejection are precisely determined based on the following rigorously tested conditions:
NF membrane (2000ppm MgSO4, 0.48 MPa, 25ºC, 15% recovery), RO membrane (2000ppm NaCl solution,
1.55 MPa, 25ºC, 15% recovery) before any hot water disinfection.
2. Please be aware that the variation range of permeate flow is +/-15%, and final water yield may vary further due to
the heat treatment process applied.
