1. For optimal performance, permeate flow rate and stabilized salt rejection are determined under meticulously 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 undergoing any hot water disinfection.
2. Please be advised, the permeate flow variation range is +/-15%. The final water yield may be subject to additional fluctuations due to
the involved heat treatment process.
