<strong>Production</strong> <strong>Aspects</strong> <strong>of</strong> <strong>Membranes</strong><br />
Polymers / What is the Desired Membrane Design?<br />
� Appearance (hollow fiber, tube, flat sheet)<br />
� Permeability <strong>and</strong> selectivity to the desired solutes<br />
� Adequate siev<strong>in</strong>g characteristics (cut <strong>of</strong>fs)<br />
� Adequate water (or solvent) permeability<br />
� Chemical <strong>and</strong> physical resistance (pH, peroxides, acids,<br />
caustics, blood)<br />
� Low amounts <strong>of</strong> extractables (TOC, toxicity)<br />
� Heat resistance (sterilizeability)<br />
� Impermeability <strong>of</strong> bacteria / viruses (pharmaceutical appl.)
