Abstract
Pleated membrane filters are used in a wide variety of applications. A model is derived to predict and optimize the performance of a pleated membrane filter (in terms of how pore radius varies in the depth of the filter membrane) as adsorptive fouling (standard blocking) occurs. For the chosen objective function the optimized pore shape is found to be funnel-like. The model may be the first to predict deterioration in particle retention with standard blocking alone.
