Filed:

May 7, 2002

Appl. No.:

10/139827

Inventors:

Larry P. Sower - Milford UT

Assignee:

Crystal Peak Farms - Milford UT

International Classification:

C01F 100

US Classification:

71 11, 71 12, 71 14, 71 15, 71 21, 71 23, 71 25, 71 28

Abstract:

Integrated waste treatment and fertilizer and feed supplement production methods to be implemented at organic waste source sites, at remote treatment sites, or partially at the organic waste source site and at a remote location, whether in small or large scale operations. The methods are suitable for retrofitting existing organic waste sources and for treating the organic waste generated by a single source or by a plurality of sources. These methods provide: Reduction or elimination of emissions of acrid and greenhouse gases; effluents that meet discharge standards and that can be used in wetland and irrigation projects; organic based, granular, slow release NPK fertilizer of standard composition and size that can be supplemented with micronutrients and soil amendment materials and whose composition can be adjusted to meet demands and needs of specific markets; methane-rich biogas recovery for its subsequent use for heating, for power generation or for catalytic and synthetic processes, and feed supplement including feed supplement for cattle. The methods comprise steps for thoroughly separating suspended and dissolved materials, preventing gas emissions and capturing gases, and minimizing waste disposal. Fertilizer base is produced by mixing waste with at least one of a phosphate precipitating agent, a base, a flocculant, and optionally with an ammonia retaining agent and a densifier, subsequently separating and drying the precipitate.

Inventors:

Larry P. Sower - Milford UT

Assignee:

Crystal Peak Farms - Milford UT

International Classification:

B01D 904

US Classification:

62532

Abstract:

Methods and systems for separation of purified water and nutrients from organic waste. Separated purified water can be used as fresh water in agricultural and farm operations, and nutrients can be converted to fertilizers. Treated organic waste includes complex organic waste with settleable and nonsettleable material that has not been subjected to a conventional lagoon primary treatment. These methodology eliminates the need for land application of residual waste stream and it comprises operations such as controlled freezing and thawing, and optionally evaporation.

Filed:

Oct 25, 2004

Appl. No.:

10/973104

Inventors:

Larry Sower - Milford UT, US

International Classification:

C02F 1/00

US Classification:

210173000, 210195100, 210209000

Abstract:

An animal waste management system for handling a waste slurry that includes coarse solids flushed from an animal confinement housing. The system comprises a surge tank for stabilizing the flow of waste slurry through the waste management system, reducing means for reducing the particle size of the coarse solids contained within the waste slurry flushed from the animal confinement housing, recycling means for recycling a portion of the waste slurry through the waste management system at a recycle rate so as to increase the concentration of solids within the waste slurry flushed from the animal confinement housing, and conditioning means for conditioning at least the recycled portion of the waste slurry to maintain air quality in the animal confinement housing.

Appl. No.:

11/005085

Inventors:

Larry Sower - Milford UT, US

International Classification:

C02F 9/00

US Classification:

210631000

Abstract:

A system and related method for concentrating a waste slurry produced from an animal confinement housing so as to significantly reduce the volume of waste requiring treatment. The system includes means for containing a volume of waste slurry produced and flushed from an animal confinement housing, means for removing a portion of the waste slurry to produce a removed portion of waste slurry, means for selectively evaporating at least some water from the removed portion of waste slurry so as to produce a concentrated waste slurry, and optionally, means for containing the concentrated waste slurry.

International Classification:

C02F 1/02

US Classification:

210175000

Abstract:

A sludge evaporation tunnel and associated method for producing a solid fertilizer product from a sludge. The sludge evaporation tunnel includes a floor surface for supporting a relatively thin layer of sludge from which water is to be evaporated, a cover over the floor for retaining heat and preventing dilution of the sludge layer by rainwater, one or more inlets for introducing sludge into the evaporation tunnel, means for moving and turning over the layer of sludge as water is progressively evaporated from the sludge, and an outlet through which the solid fertilizer product exits. The sludge evaporation tunnel may form part of a larger waste treatment system that includes a digester or anaerobic lagoon, which separates a waste animal slurry into sludge and a dilute waste slurry, and a dilute waste evaporation tunnel.
