Abstract: A system and method for treating farm animal waste, such as hog and poultry waste, to remove volatile organic compounds (VOCs) from wastewater treatment pits and thus control smell is disclosed. The farm animals are housed in structures equipped with grated flooring to permit animal waste to fall into pits or reservoirs below. The pits contain water inoculated with a special assemblage of natural microbes to which oxygen is supplied through piping arranged in the pits. These special microbes have an affinity for ammonia and convert much of the animal waste into carbon dioxide, fatty acids, and water. The system also includes a second piping network situated beneath the grated flooring which serves to create a negative air situation by which escaping foul-smelling air is pulled back into the wastewater to permit further action on the VOCs by the microbes in the water.

Abstract: A system for capturing HAPs/VOCs from an existing or planned air stream and destroying the contaminants in the air stream by microbial degradation is disclosed. In general, the system is composed of a reservoir with a filter structure positioned above it. The filter structure contains a capture or filtration media through which contaminated air or vapors must pass. HAPs/VOCs in the air or vapors are filtered out and absorbed by the capture media. The reservoir contains a tank water bath that is inoculated with microorganisms that are selected to degrade the hazardous materials or pollutants removed by the capture media. Sprinkler heads above the filter structure spray the filter structure with a sprayed water bath also inoculated with the microorganisms, whereby contaminants caught in the filter structure are leached out and bioremediated.

Abstract: A system for capturing HAPs/VOCs from an existing or planned air stream and destroying the contaminants in the air stream by microbial degradation is disclosed. In general, the system is composed of a housing that contains a rotating drum. The drum contains a capture or filtration media through which contaminated air or vapors must pass. HAPs/VOCs in the air or vapors are filtered out and absorbed by the capture media. The rotating drum sits in a water bath that is inoculated with microorganisms that are selected to degrade the hazardous materials or pollutants removed by the capture media.
