ABSTRACT:
A method and system for wastewater treatment is described and is particularly suitable for manure lagoons and pits. Specifically, an ozone gas is homogeneously distributed through an upper stratum of a contained liquid thereby creating an aerobic "cap", while still maintaining an anaerobic lower stratum. A perforated tube or plurality of tubes fixed within the upper stratum serves to distribute the ozone. Alternately, a buoyant vehicle propelled across the surface of the liquid may also serve to distribute the ozone and create the ozonated "cap". The vehicle provides an additional benefit of crust fragmentation and prevention thereby inhibiting and eliminating fly propagation, and hygienically improving lagoon or 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 sometimes found in water recycled from the containment area.
