1. For peak performance, permeate flow rate and stabilized salt rejection have been meticulously determined under 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) before any hot water disinfection process.
2. It is important to note that permeate flow variations are within a +/-15% range, and the final water yield may experience additional fluctuations due to
the heat treatment process involved.
