A separator system and method may provide a four-way separator that may separate a material and remove a hazardous material. The hazardous material may include gas and sand that may be removed by the four-way separator. The separator system and method may further provide a main unit that may include three chambers or recirculation hoppers, an auger sand extractor, and a strap tank. The separator system and method may provide a faster rig-up time and may be exclusively driven by hydraulics.

A system for recovery of animal byproducts and providing water reuse from an animal processing plant waste stream. In one embodiment of the invention there is an equalization tank forming part of an animal processing plant that is mechanically filtered to recover animal byproducts from a water mixture in the equalization tank. In another aspect of the invention there is a skimmer tank that contains a skimmer mixture with water and animal byproducts. The system mechanically separates the animal byproducts from the skimmer mixture in a manner that is suitable for human consumption. The system also allows the separated water to be reused in the animal processing plant.

A flow back system for separating solids from a slurry recovered from a hydrocarbon well. The system includes a V-shaped tank with a first series of baffles configured to cause the settling of solids that are moved by a shaftless auger to a conduit fluidly connected to hydrocyclones mounted over a linear shaker. The overflow from the hydrocyclones is discharged through a second conduit back into the tank for processing by a second series of baffles resulting in a clean effluent. The clean effluent is recirculated in the well.

The invention relates to a water treatment plant which comprises means (38) for supplying the water to be treated, means (31) for supplying coagulant reagent (21), a flocculation-decantation device (1) which has means (32) for dispensing the flocculant reagent, means (33) for distributing ballast, means (39d) for extracting decantation sludge and means (9) for discharging water that has been treated, a line (8) for supplying coagulated water to the flocculation-decantation device (1), means (24) for separating the ballast contained in the ballasted sludge followed by means (36) for recycling the ballast back into said flocculation-decantation device (1), characterised in that said device (1) comprises an outer tank (2) that has a first hopper (4), and at least one inner tank (3) that has a second hopper (5) and is arranged inside said outer tank (2); the inner tank (3) receiving the flocculant and the ballast and comprising stirring means (10), wherein a peripheral space is disposed between the inner tank (3) and the outer tank (2); the second hopper (5) having an opening (6) which opens into the first hopper (4); and said first hopper (4) having an outlet that communicates with the means (34) for discharging ballasted sludge, wherein the means (9) for discharging water that has been treated are disposed in the upper portion of said outer tank (2). The invention also relates to a method for implementing a plant of this types.

An apparatus for gas and solids separation from down-hole fluids having an inner tube and an outer tube disposed about the inner tube. The annular region between the tubes contain a plurality of chambers, separated by fluid barriers. The chambers include an intake chamber to receive fluids from outside of the outer tube through an orifice, and processing chambers. Fluid communication between the intake and processing chambers is restricted to fluid flow through sets of tubes. Fluid communication between a lowermost processing chamber below the intake chamber and a lower processing chamber above the intake chamber is restricted to fluid flow through the inner tube. A block restricts fluid communication within the inner tube to other chambers above the intake chamber. Orifices in the inner tube of the processing chambers on either side of the block provide fluid communication across the block.

The invention relates to a water treatment plant comprising: means (1) for supplying water for treatment, wherein said water has been coagulated previously, a flocculation-decantation device (11) having means (5) for dispensing at least one flocculant reagent, means (6) for dispensing at least one ballast, means (20d) for extracting decantation sludge, means (9) for discharging the treated water, means (14) for separating said ballast contained in the ballasted sludge, and means (8) for recycling the ballast that has been cleaned in this manner back into the flocculation-decantation device (11), characterised in that: said flocculation-decantation device (11) has a single tank (12) in the lower portion of which a stirring mechanism (13) is arranged; wherein said single tank (2) comprises slats (10) in its upper portion; and said slats are separated from the stirring mechanism (13) by a distance d which is between approximately 0.5 metres and approximately 3 metres. The invention also relates to a method using said plant.

Provided is a cutting fluid tank for a machine tool, which is capable of sufficiently collecting and removing sludge mixed in a cutting fluid even when a chip conveyor or the like is disposed in a tank main body, and with which a location where sludge remains accumulating on a bottom of the tank main body is less likely to occur even when an operation is restarted after being suspended. A cutting fluid tank includes: a tank main body; a first circulation pump; a sludge transfer nozzle configured to eject the sludge-containing cutting fluid pumped out by the first circulation pump, toward a sludge collection pump; a second circulation; and first agitation nozzles configured to eject the sludge-containing cutting fluid that is pumped out by the second circulation pump, toward predetermined points in the tank main body.
