The filtration device of the present invention relies on materials and
methodologies that achieve the formation of a structural matrix that may
later accommodate the addition of other adsorbent materials as opposed to
merely binding adsorbent materials together through the use of
compression and/or binder materials. The filter device of the present
invention relies on (i) a unique method of processing to achieve maximum
density of materials, (ii) a polymeric material having a distinct
morphology and (iii) a very small micron diameter of the polymeric
material to create uniformity. For example, in place of compression to
increase density, the materials comprising the filtration device of the
present invention are instead vibrated into a mold cavity. Thus, the
methodology of the current invention optimizes how all of the materials
comprising the filtration device fit together without compaction. The
material being processed is vibrated as it is gradually poured into the
mold. Once the mold cavity has been filled to a point where it will hold
no more material, it is heated and then cooled. In place of an external
binder, the structural material adheres to itself as it softens. This
results in a tortuous path matrix of pores rather than an absolute pore
barrier.
