1. To ensure peak performance, permeate flow rate and stabilized salt rejection are meticulously calibrated based on 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 note, the variation range of permeate flow is +/-15%, and the final water yield may experience additional fluctuations due to
the heat treatment process involved.
