Optimizing Tangential Flow Filtration

Web(Figure 2). The rate of clean water flux through the membrane is measured as liters per membrane area per hour (L/m2-h). Water flux divided by the transmembrane pressure is the normalized water permeability or NWP (L/m2-h-bar). The NWP values are compared to initial (pre-process) levels and may be analyzed for trends over time.
