1. Achieving peak performance requires careful calibration of permeate flow rate and stabilized salt rejection, based on these rigorously validated standard testing conditions:
NF membrane (2000ppm MgSO4, 0.48 MPa, 25ºC, 15% recovery), RO membrane (2000ppm NaCl solution,
1.55 MPa, 25ºC, 15% recovery) prior to any hot water disinfection.
2. Please be aware, the permeate flow variation range is +/-15%, and final water yield may fluctuate further due to
the intricate heat treatment process involved.
