Abstract

A fiber containing a bound active material, such as. a metal oxide, under 20 microns in diameter. The inventive fiber is formed through the mixing of the fibers with a cationic or anionic polymer in one tank, the active material with a cationic or anionic polymer in a second tank, the opposite zeta potential of that used with the active material, and then mixing the active material/polymer and fiber/polymer blends together.

Claims

exact text as granted — not AI-modified
1 .- 6 . (canceled) 
     
     
         7 . An improved. filter material comprising a plurality of fibers having a bound active material, said active material having a diameter less than 20 microns.. 
     
     
         8 . The improved filter material of  claim 7  wherein the active material comprises a metal oxide. 
     
     
         9 . The improved filter material of  claim 7  in combination with carbon block. 
     
     
         10 . The improved filter material of  claim 7  in combination with carbon sheets. 
     
     
         11 . The improved filter material of  claim 7  in combination with a second filtration media, whereby the improved filter material services as a precoat for said second filtration media.
