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. Webcellulose membrane. Stable process pressures and flow conditions indicate absence of plugging and suitability of cassette design. No Protein Loss Samples of composite permeate from each process run were analyzed for protein using the biuret method. No protein loss was detected in the permeate, indicating greater than 99.9% protein yield.
