    Abstract: A feed system for a rotary screen separator has a feed housing and a feed lid movably attached to the feed housing. The feed housing has a feed chamber, an inlet opening, and an 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 an 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 feed lid is movably attached to the feed housing such that the feed lid covers the outlet opening in a closed position, and does not cover the outlet opening in at least one open position.

    Abstract: A processing system for processing raw slurry material comprising at least liquid, sand, and contaminates comprises a barrel member, at least one transport member, at least one separator member, and a drive system. As the drive system rotates the barrel member about the barrel longitudinal axis, a portion of the raw slurry material is transported through a pre-processing portion of the processing chamber. At least a portion of the liquid and at least a portion of the contaminates in the raw slurry material flows back down the pre-processing portion of the processing chamber towards a barrel inlet. At least one intermediate opening is arranged such that at least a portion of the contaminates in the raw slurry material flowing down through the pre-processing portion of the processing chamber passes through the at least one intermediate opening.

    Abstract: A rotary screen separator for processing feed material comprising liquids and solids, the rotary screen separator comprising a separator member, a collector structure, a drive system, and first and second vane structures. The separator member defines a first perforation region and a second perforation region. The collector structure defines a first material output and a second material output. The vane structures are supported relative to the separator member such that operation of the drive system to rotate the separator member causes the first vane structure to displace the feed material through the first perforation region at a first material displacement rate and the second vane structure to displace the feed material through the second perforation region at a second material displacement rate. The first material displacement rate is greater than the second material displacement rate.

    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 digester system comprising a primary digester tank containing a primary feed material portion, a secondary digester tank containing a secondary feed material portion, a first conduit connected between the primary digester tank and the secondary digester tank to define a primary tank lower opening within the primary digester tank and a secondary digester tank lower opening within the secondary digester tank, and a flow control valve configured to allow or prevent flow of fluid through the first conduit. When the flow control valve is configured to allow flow of fluid through the first conduit, a portion of the primary feed material portion flows from the primary digester tank to the secondary digester tank to form the secondary feed material portion.

    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.
