Title: System and method for treating animal waste

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.
