1. To guarantee exceptional performance, the permeate flow rate and stabilized salt rejection are meticulously determined based on the following rigorously evaluated 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.
2. Please be aware, the permeate flow variation range is +/-15%, and the final water yield might experience additional fluctuations due to
the incorporated heat treatment process.
