<p>A method and system for ozone injection into a livestock building (2) is described. Ozone is homogeneously transferred, preferably from a remote location, throughout the air in the building (2) at levels considered save by OSHA. Ozone thus affects a reduction in dust, flies, and relative humidity, thereby inhibiting primary disease-causing vectors. Ozone is also homogeneously distributed through an upper stratum (20) of manure liquid contained within a pit (4) in the building (2) thereby creating an aerobic 'cap' (20), while still maintaining an anaerobic lower stratum. A perforated tube or plurality of tubes (36) fixed within the upper stratum (20) serves to distribute the ozone. Ozone applied in this environment unexpectedly inhibits the fly population through retardation of larvae maturation. Alternatively, a buoyant vehicle (40) propelled across the surface (16) of the liquid may also serve to distribute the ozone and create the ozonated 'cap' (20). The vehicle (40) provides an additional benefit of crust fragmentation and prevention thereby further inhibiting and eliminating fly propagation, and hygienically improving pit operation. In either embodiment, the ability to create an aerobic and anaerobic balance within the liquid facilitates a reduction in odor, a significant improvement of organic digestion and solids control, and a reduction in pathogens often found in water recycled from the containment area (4).</p> |
