Critical Time and Flow Rate at which Filterability Deterioration Rates are maximized. For the surfaces interpolated in Figure 3, the gradient was calculated using the gradient function in MATLAB with increment size of 0.1 weeks and 10 μL min⁻¹. The magnitude of the filterability gradient, (2), was calculated at every point on the surface, and the times and flow rates corresponding to the maximum magnitude of the filterability gradient were averaged and displayed here.
