For microfiltration or ultrafiltration membranes, both clean water flux and particulate
fouling (blocking of pores by particles) are thought to be a function of the pore area and shape. In
this research, commercial membranes have been uni-axially stretched to alter the pore shape, and
their performance was evaluated with respect to clean water flux, flux decline when filtering a
suspension, and particle rejection. Polyethylene terephthalate (PET) track-etched membranes with
mono-sized circular pores from 1 to 10 µm and polyether sulfone (PES) phase-inversion
membranes with nominal pore sizes ranging from 0.2 to 5 µm have been stretched in the range of
12 to 150%.
