Abstract
A system for removing undesirable compounds from contaminated air includes a biofilter having sintered glass media. Hydrogen sulfide is removed from contaminated air by passing the contaminated air through the biofilter.
Claims19
A gas phase biofilter for the treatment of contaminated air, the biofilter comprising:
- a contaminated air inlet;
- a treated air outlet;
- and
- a media bed including foamed glass media in fluid communication between the contaminated air inlet and the treated air outlet.
A method of removing an undesirable compound from contaminated air, the method comprising introducing contaminated air through a gas phase biofilter including a foamed glass media.
The method of claim 19, wherein passing contaminated air at a flow rate of greater than about 250 cubic meters per hour per cubic meter of the media bed through the media bed comprises passing the contaminated air at a flow rate of greater than about 500 cubic meters per hour per cubic meter of the media bed through the media bed.
