A filter for use in the treatment of contaminated fluid is provided. The filter, in an embodiment, includes two filter elements, each substantially flat in shape, for use in removing certain contaminants from the fluid flow. The filter further includes a waste adsorbent material, positioned between the two filter elements for use in removing additional contaminants within the fluid flowing across the filter elements. The waste adsorbent material, in an embodiment, may be a nanosorbent material manufactured from self-assembled monolayers on mesoporous supports (SAMMS). The filter can form a barrier through which contaminated fluid flows for removing certain contaminants from the fluid.
