Patent ID: 7311743

Claim:
A filtration apparatus for filtering methyl bromide from a volume of methyl bromide-containing gas, comprising: a housing having a first end, a second end, and a sidewall extending from the first end to the second end to define an interior compartment; a contaminated gas inlet located on the housing to direct methyl bromide-containing gas into the interior compartment; a filtered gas outlet located on the housing to direct filtered gas out from the interior compartment; and a substrate component comprised of an inert material located in the interior compartment, the substrate component having located therein a population of methyl bromide-degrading microorganisms effective in degrading methyl bromide present in a volume of gas passed from the contaminated gas inlet into the interior compartment, and a biotrickling filter, including a nutrient dispersion device, sufficient to disperse nutrients through the substrate component and continuously purge the substrate of bromine ions.
