1. To guarantee peak performance, the permeate flow rate and stabilized salt rejection are meticulously determined under the following 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 undergoing any hot water disinfection process.
2. Please be aware, the permeate flow variation range stands at +/-15%, and the ultimate water yield might face additional changes due to
the intricacies of the heat treatment process involved.
