1. To ensure superior performance, both permeate flow rate and stabilized salt rejection are determined under rigorously verified standard conditions:
NF membrane (2000ppm MgSO4, 0.48 MPa, 25ºC, 15% recovery), RO membrane (2000ppm NaCl solution,
1.55 MPa, 25ºC, 15% recovery) before executing any hot water disinfection process.
2. It is important to note that the variation range for permeate flow is +/-15%, and final water output may vary due to
the thermal processing involved.
