Abstract: A separation system for separating solids from a slurry of waste material, the separation system comprising a housing, a drum assembly, and a drive assembly. The housing defines a collection chamber. Liquid within the collection chamber defines a liquid level. The drum assembly defines a perforated cylindrical wall and the drum assembly is supported such that at least a portion of the drum assembly is below the liquid level. The drive assembly rotates the drum assembly relative to the housing.

Abstract: A method and apparatus for collecting agricultural manure in a confined animal feeding operation includes a separator which receives heavy manure removing particulate from suspension to produce light manure. Heavy manure is collected to a volume of heavy manure sufficient to substantially fill the first tank. Within the first tank, particulate migrates, due to the influence of gravity to form a layer containing manure comprising a lesser density of particulate than is present in the volume of heavy manure. Additional heavy manure buoys the layer such that the upper surface exceeds a height of a weir. The weir is situated in a channel communicating between the first tank and a second tank configured to receive light manure from the separator.

Abstract: A feed system for a rotary screen separator has a feed housing and at least one feed lid movably attached to the feed housing. The feed housing has a feed chamber, an inlet opening, and at least one outlet opening. The feed chamber defines a proximal portion adjacent to the inlet opening and a distal portion at least a portion of which is adjacent to the at least one outlet opening. A cross-sectional area of at least a portion of the proximal portion is greater than a cross-sectional area of the distal portion. The at least one feed lid is movably attached to the feed housing such that the at least one feed lid covers the at least one outlet opening in a closed position, and does not cover the at least one outlet opening in at least one open position.

Abstract: To produce fertilizer, a system and method concentrates manure slurry in a mechanical vapor recompression evaporator (“MVR”) having a heat exchanger. The MVR receives the manure slurry within a first side to evaporate ammonia laden-water vapor from the slurry, leaving a nutrient concentrate. A compressor raises the evaporated ammonia-laden water vapor to a higher energy state. Within a second side of the heat exchanger, the compressed water vapor conveys heat to the slurry. Ammonia-laden water condenses in the second side at a process temperature to be conveyed to an ammonia stripping tower where the ammonia-laden water is dispersed into ammonia-laden water droplets. In the tower, a flow of air is directed across a surface of the ammonia-laden water droplets, the process temperature having been selected to promote the escape of ammonia gas from the ammonia-laden water droplets, the flow of air provided to entrain ammonia gas in the flow.

Abstract: A processing system for separating raw slurry material into particulate materials and liquid materials comprising a processing structure, a frame, and a drive motor. The processing structure defines a processing chamber, an inlet, an outlet, and at least one pre-processing opening arranged between the inlet and the outlet. The frame supports the processing structure. Operation of the drive motor rotates the processing structure such that at least some of the particulate materials in the raw slurry material are transported from the inlet to the outlet, at least some of the liquid materials in the raw slurry material are allowed to flow back towards the inlet, and at least some of the liquid materials and at least some of the particulate materials are allowed to flow through the at least one pre-processing opening.

Abstract: A processing system for processing raw slurry material has a barrel member, at least one transport member, and at least one separator member. The barrel member defines a processing chamber and at least one intermediate opening. The processing chamber defines a pre-processing portion and a separator portion. The at least one transport member is arranged within the pre-processing portion of the processing chamber. The at least one separator member is arranged within the separator portion of the processing chamber and configured to define at least one separator gap. As the barrel member rotates about a longitudinal axis thereof, the at least one transport member transports at least a portion of the raw slurry material through the pre-processing portion of the processing chamber, and the at least one separator member transports at least a portion of the raw slurry material through the separator portion of the processing chamber.

Abstract: A separation system for separating solids from a slurry of waste material employs first and second separator assemblies. The first separator assembly has a main housing and a perforated drum supported for rotation relative to the main housing. The second separator assembly has a barrel member and an auger blade supported for rotation relative to the barrel member. The main housing is fixed relative to the barrel member such that rotation of the perforated drum removes a first solids portion from the slurry of waste material and rotation of the auger member removes a second solids portion from the slurry of waste material.
