ABSTRACT
This chapter focuses on filtration developments, specifically charged filter media, as
applied to primarily pharmaceutical and beverage applications. There are many
examples where the use of charged filter media has been applied to additional fluid
purification areas including microelectronics integrated circuit manufacture (Stone and
Parekh, 1993), wastewater remediation (Hagg, 1998), water treatment (Mika et al.,
1999), and others. Several reviews addressing the charged filtration media development
and implementation are available in the literature (Andelman, 1995; Zeman and
Zydney, 1996;). Further, the use of charge enhanced media has been applied to nearly
the full range of filtration types, encompassing microfiltration, ultrafiltration,
nanofiltration, and even reverse osmosis membranes (Ebersold and Zydney, 2004).
Charged media has also been used in “non filtration” applications such as
chromatographic separation (Zhou and Tressel, 2006).
