20130260443 | ODOR FILTER - A portable odorous gas filter may provide for substantially even distribution of byproduct gas throughout a containment vessel by utilizing a diffuser plate having a plurality of holes therein. Byproduct gas from manufacturing or treatment processes may be directed into a gas plenum layer in the containment vessel through an inlet below the diffuser plate. The geometry of the diffuser plate may provide for a high-pressure differential between the plenum layer below the plate and a filter layer containing an odor-filtering media above the plate. Certain types bacteria and/or fungal strains may be added to extend the effective life of the biological media used therein. | 10-03-2013 |
