ABSTRACT:
A rotary filtration device having at least two members, one at least partially within the other to define a fluid gap therebetween, is disclosed. One or more filters are located on one or more of the members facing the fluid gap. Sufficient uncharged hydrophilic polar groups, preferably uncharged substituted amide groups, are located on the surface of the filter to render the surface hydrophilic.
