1. For peak performance, the permeate flow rate and stabilized salt rejection are precisely based on these rigorously standardized test conditions:
NF membrane (2000ppm MgSO4, 0.48 MPa, 25ºC, 15% recovery), RO membrane (2000ppm NaCl solution,
1.55 MPa, 25ºC, 15% recovery) before undergoing any hot water disinfection.
2. Be aware, the permeate flow variation is +/-15%, and the final water yield may exhibit further fluctuations due to
the integration of the heat treatment process involved.
