ABSTRACT:
A method of making a filter media for use in a filter employed to separate water and particulate material from a liquid to be purified, such as a hydrocarbon fuel. The method includes the steps of providing a fibrous mat of material adapted to mechanically separate particulate material from a liquid to be purified, applying starch-polyacrylonitrile graft polymer in dry, granular form to the mat, and fixing the co-polymer to the mat by spraying the mat with a volatile solvent containing a small amount of water.
