Claim:
An apparatus for removing odor from a contaminated airstream from a wet well, comprising: a) a first housing, a first inlet disposed on said first housing for inletting the airstream into said first housing, a first outlet disposed on said first housing for discharging the airstream from said first housing; b) a filter disposed in said first housing for filtering the airstream, said filter being a dry filter, wherein said filter is disposed internal said first housing so that the airstream passes through said filter between said first inlet and said first outlet; c) a second housing, a second inlet and a second outlet disposed on said second housing, wherein said first outlet is connected to said second inlet so that said second housing receives the airstream from said first housing; d) a first and second compartment disposed in said second housing, said second compartment disposed above said first compartment, said second inlet disposed on said first compartment so that the airstream enters said first compartment and said second outlet disposed on said second compartment so that the airstream is discharged from said second compartment; e) a treatment fluid for removing odor from the airstream, wherein said treatment fluid is disposed in said first compartment; f) a plurality of diffusers disposed under a surface of said treatment fluid, wherein said second inlet connects to said diffusers so that the airstream passes through said diffusers and into said treatment fluid so that odor is removed from the airstream, wherein froth is generated as the airstream passes through said treatment fluid; g) at least one plate disposed between said first compartment and said second compartment so that said plate is above said surface of said treatment fluid, said plate having a plurality of holes therein, wherein said froth is captured on said plate so that said froth is removed from the airstream; and, h) a vacuum pump disposed in said second housing for vacuuming the airstream through the apparatus so that the airstream is conveyed from said first inlet to said second outlet, wherein odors are substantially removed from the airstream.
