Patent ID: 8546298

Claim:
A method of producing a filtration media having a chemical reagent comprising the step of: mixing H 2 O, KMnO 4 , and at least one member from the group consisting of NaCl, Na 2 SO 4 , Na 2 BO 3 , Na 2 CO 3 , Na 3 PO 4 , NaNO 3 , LiCl, Li 2 SO 4 , Li 2 BO 3 , Li 2 CO 3 , Li 3 PO 4 , LiNO 3 , KCl, K 2 SO 4 , K 2 BO 3 , K 2 CO 3 , K 3 PO 4 , KNO 3 , NH 4 Cl, (NH 4 ) 2 SO 4 , (NH 4 ) 2 BO 3 , (NH 4 ) 2 CO 3 , (NH 4 ) 3 PO 4 , and NH 4 NO 3 , or from the group consisting of MgCl 2 , MgBO 3 , Mg(NO 3 ) 2 , CaCl 2 , CaBO 3 and Ca(NO 3 ) 2 , forming an impregnating solution; heating said impregnating solution; combining an activated alumina support with said impregnating solution in an amount sufficient to form a coherent mass; mixing and heating said impregnating solution and said activated alumina support; and curing said impregnating solution and said activated alumina support forming said coherent mass, wherein said curing is performed without allowing the curing to proceed to completion and is followed by the steps of: granulating said coherent mass into granules; compression forming said granules into a desired shape; and further curing to completion said shaped granules forming said filter media.
