ABSTRACT:
Filter element package, method for preparing and method of using the same for treating contaminated aqueous solutions, in which the filter element is in the form of a mat consisting essentially of a wet laid, porous, non-woven matrix having randomly arranged, irregularly intersecting and overlapping cellulose fibers intermixed with polymer micro-bits. The filter mat, either alone or confronted with a supporting sheet of material, is provided in a predetermined geometrical shape and folded along perpendicular lines to form a four-layered filter element which can be displaced into a cone-shaped structure for filtering contaminated aqueous solutions. A resealable envelope is provided for enclosing the filter element and may include therein a bracing member to provide lateral support for the filter element during filtering and/or a collapsible receptacle for containing a predetermined quantity of the solution to be treated along with a packet of disinfectant for disinfecting the same.
