1. To achieve peak performance, the permeate flow rate and salt rejection stabilization are determined under meticulously tested standard conditions:
For NF membranes (2000ppm MgSO4, 0.48 MPa, 25ºC, 15% recovery), and RO membranes (2000ppm NaCl solution,
1.55 MPa, 25ºC, 15% recovery) prior to undertaking any hot water disinfection process.
2. Please be aware that the permeate flow variation is within +/-15%, and the ultimate water yield may vary further due to
the intricacies of the heat treatment process involved.
