1. To deliver peak performance, the permeate flow rate and stabilized salt rejection are meticulously determined under these rigorously verified 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. Be aware that the flow of permeate may vary within a range of +/-15%, and the final water yield could be affected by additional fluctuations due to
the intricate heat treatment process involved.
