Abstract
A method for forming a filtration media from waste media includes combining the waste media with a binder to form a dry mixture, adding a liquid composition to the dry mixture to form a slurry, and extruding the slurry to form a filtration media. The waste media may include fines or oversized media resulting from a prior media production process that have been subjected to a hydration process. The waste media may be ground and sized prior to combining it with the binder. The binder may include clay, cellulose materials, and combinations thereof. The liquid composition may include water and optionally one or more additional additives selected from the group consisting of permanganates, acids, bases, amines and combinations thereof. In one embodiment, the slurry is extruded into a honeycomb matrix.
