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 rotary screen separator for processing feed material comprising liquids and solids, the rotary screen separator comprising a separator member, a collector structure, 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 rotating 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: 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.

Abstract: A processing system for processing raw slurry material comprising a barrel member defining a feed portion, a processing chamber, and an outlet opening, at least one pre-processing member, and at least one pre-processing opening formed in the barrel member adjacent to a first portion of the pre-processing member. As the barrel member rotates, the at least one pre-processing member transports at least a portion of the raw slurry material such that at least some of the heavy particulate material in the raw slurry material is transported to the outlet opening, at least some of the liquid material in the raw slurry material is allowed to flow back towards the feed portion, and at least some of the liquid material and at least some of the light particulate material is allowed to flow through the at least one pre-processing opening.

Abstract: A processing system for processing raw slurry material comprises a barrel member defining a processing chamber, at least one intermediate opening, and an outlet opening, a trough system arranged to contain the raw slurry material, at least one transport member, and a drive system. As the drive system rotates the barrel member, the at least one transport member transports at least a portion of the raw slurry material from the trough system and through the processing chamber such that at least a first portion of the raw slurry material is transported to outlet opening, at least a second portion the raw slurry material exits the processing chamber through the intermediate opening, and at least at third portion of the raw slurry material is allowed to flow back towards the trough system.

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: A pre-separator for a screw press separator wherein the pre-separator increases the concentration of solid material in a water solid material mixture. The pre-separator is configured to have a frustoconical screen surface where a plurality of wiper blades engage the interior portion of the surface to provide de-watering action, and the plurality of blades are configured to reposition with respect to the center axis of the frustoconical surface to allow for engagement between the interior surface of the frustoconical screen, and the wiper blades.

Abstract: A flush system for processing waste slurry contains animal waste, comprising a primary separator, a primary digester, and a secondary digester. The primary separator separates the waste slurry into a first portion and a second portion. The primary digester digests the first portion. The secondary digester digests at least part of the second portion. A solids content of the first portion is higher than a solids content of the second portion.

Abstract: A cleaning system for a dairy facility comprising a rinse system including a rinse sprayer, a flush system comprising a process system for processing waste water to obtain processed water, a collection system connected between the dairy facility and the process system, and a flush sprayer. The rinse sprayer sprays rinse water in a first zone of the dairy facility, where the rinse water becomes waste rinse water after the rinse water has been sprayed in the first zone of the dairy facility. The flush sprayer sprays the processed water in a second zone of the dairy facility, where the processed water becomes waste processed water after the processed water has been sprayed in the second zone of the dairy facility. The collection system collects the waste rinse water and the waste processed water to form the waste water and directs the waste water to the process system.

Abstract: The present invention may be embodied as a rotary screen separator for processing feed material. A separator member defines a longitudinal axis, an input port, an output port, a fine perforation region, and a coarse perforation region. A collector structure defines a fine material output and a coarse material output. A support structure supports the separator member and the collector structure. A drive system rotates the separator member relative to the support structure. Operation of the drive system displaces feed material through the fine perforation region and the coarse perforation region. A first portion of the feed material flows through the separator member to the fine material output in the fine perforation region. A second portion of the feed material flows through the separator member to the coarse material output in the coarse perforation region. A third portion of the feed material flows through the output port.

Abstract: A rinsing system for rinsing fibrous material providing a separator with counter current flow of the fibrous material with respect to a rinsing fluid in a second separator. The system provides for a first separator which in one form removes water from the fibrous material to increase the dilution factor whereby the fibrous material in the second separator passes therethrough and in one form passes through a dewatering mechanism.
