Abstract
Disclosed is a system and method of digesting raw animal waste using diffusers to force circulation and aerate a digesting lagoon. Several lagoons may be used in series to treat raw waste and different variations may be employed to successively digest raw waste. Aeration with slightly ozonated air facilitates a blend of aerobic and anaerobic microbes to quickly and completely digest large amounts of raw animal waste.
Claims7
A system for the digestion of biological wastes comprising:
- a first water filled lagoon having an inlet and outlet;
- a compressed air supply;
- a blend of microbes comprising at least one of the following:
- Bacillus, Saccharomyces, and Thiobacillus, said blend of microbes present in said first water filled lagoon;
- a plurality of aerators disposed on the bottom of said first water filled lagoon, said aerators connected to said compressed air supply and adapted to produce a laminar column of bubbles;
- a second water filled lagoon having an inlet and outlet wherein said inlet of said second water filled lagoon is connected to said outlet of said first water filled lagoon;
- and
- a plurality of aerators disposed on the bottom of said second water filled lagoon, said aerators connected to said compressed air supply.
5 more elements
A system for the digestion of biological wastes comprising:
- four water filled lagoons, each of said four water filled lagoons having a conical bottom wherein said conical bottom comprises a sludge drain, each of said water filled lagoons further having an inlet and outlet arranged such that water may flow in succession from the first water filled lagoon to the fourth water filled lagoon;
- a sludge pit connected to the sludge drains of each of said four water filled lagoons;
- a pump adapted to move said sludge from said sludge pit to said first water filled lagoon;
- a compressed air supply;
- a plurality of aerators disposed on the bottom of said each of said four water filled lagoons, said aerators connected to said compressed air supply and adapted to produce a laminar column of bubbles;
- a blend of microbes comprising at least one of the following:
- Bacillus, Saccharomyces, and Thiobacillus, said blend of microbes present in said first water filled lagoon;
- and
- at least one surface circulator in said each of said water filled lagoons adapted to circulate the liquid in each of said water filled lagoons.
