1. To guarantee supreme performance, the permeate flow rate and stabilized salt rejection are carefully determined based on the following stringently 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 procedures.
2. Please be advised that the variation range of permeate flow is +/-15%, and the ultimate water yield may undergo additional changes due to
the heat treatment process implemented.
