1. For peak performance, the permeate flow rate and stabilized salt rejection are determined under meticulously tested standard conditions:
For NF membranes, conditions include 2000ppm MgSO4, 0.48 MPa, 25ºC, with 15% recovery. For RO membranes, conditions are 2000ppm NaCl solution,
1.55 MPa, 25ºC, with 15% recovery, all prior to any hot water disinfection process.
2. It is crucial to acknowledge that the permeate flow's variation margin is +/-15%, with final water yield possibly undergoing further fluctuations due to
the intricacies of the heat treatment process integrated.
