1. To guarantee superior performance, the permeate flow rate and stabilized salt rejection are meticulously based on the following rigorously established standard conditions:
NF membrane (2000ppm MgSO4, 0.48 MPa, 25ºC, 15% recovery), RO membrane (2000ppm NaCl solution,
1.55 MPa, 25ºC, 15% recovery) before initiating any hot water disinfection.
2. Please take note, the permeate flow may vary by +/-15%, and the final water yield might undergo additional fluctuations attributable to
the requisite heat treatment procedure.
