Abrégé

The present disclosure relates to processing organic compounds, such as manure or other organic waste, comprising a first containment or mixing chamber, a first anaerobic chamber, and a second anaerobic chamber. A first anaerobic chamber may receive organic compounds from a first containment or mixing chamber, and may provide a fluid stream to a second anaerobic chamber. The second anaerobic chamber may comprise a substrate, such as lava rock, with bacteria growing thereon. Further, biogas generated in one or both of the first anaerobic chamber and the second anaerobic chamber may be purified in a first stage using a water scrubber to remove a majority of the carbon dioxide and other contaminants from the biogas, and in a second stage using a pressure swing adsorption unit to reduce carbon dioxide and other contaminants to pipeline acceptable levels. Further yet, carbon dioxide and hydrogen sulfide gases generated during the biogas purification process may be injected into a water-containing chamber in the presence of bacteria and oxygen to convert the hydrogen sulfide to elemental sulfur and/or sulfate.

Abrégé

The present disclosure relates, according to some embodiments, to systems and methods for processing organic compounds, such as manure or other organic waste. Embodiments may comprise a first containment chamber, a first anaerobic chamber, and a second anaerobic chamber. A first anaerobic chamber may receive organic compounds from a first containment chamber, and may provide a fluid stream to a second anaerobic chamber. The second anaerobic chamber may comprise a substrate, such as lava rock, with bacteria growing thereon. Further, a sulfide gas treating unit may receive and treat sulfide gases from a first anaerobic chamber and/or a second anaerobic chamber. A water storage unit may receive and store waste water or effluent from a first anaerobic chamber and/or a second anaerobic chamber.
