Normalized permeate flow calculation
WebImmediately set the pressure regulator for 30 psi (2 bar) and measure the seconds for 500 mL to permeate using the graduated cylinder. Allow flow to continue through the filter for 15-minutes if possible and repeat the cylinder timing. If more than twice the initial timing, repeat the test with a new filter using a 5 or 10 minute span. Web16 de set. de 2024 · Normalized permeate flow or NPF is reflective of the amount of permeate water being produced. As a standard, when this value drops by 10 to 15 percent, it means that it is time to clean the membranes.
