ABSTRACT:
An odor collection station for a waste water lagoon with a buoyant housing having a top, open bottom, and opposite side and end walls. The housing having a U-shaped duct with an upper and lower passageway connected by a vertical passageway. Buoyant elements secured to the housing maintain the lower passageway at a level higher than the water surface. Compressed air forced through an inlet port of the lower passageway combines with odors that rise from the lagoon surface and are pumped through the vertical and upper passageway to an outlet port where odor components are contained, measured, and analyzed.
