A sedimentation device for material which is contained in fluid, in particular rainwater, includes a sedimentation insert (12) which in the position of use is inserted into a shaft element (12), wherein the sedimentation insert (12) includes a run-in chamber, said run-in chamber being delimited by a run-in chamber side wall (20) which provided with a lateral run-in opening (19) and on its lower side having an outlet opening (23), wherein a flow-breaking device (24) for breaking the flow of a fluid flow which is produced in a throughflow direction (26) between the run-in opening (19) and a run-out opening (25) is assigned to the outlet opening (23), and wherein the sedimentation insert includes a run-out chamber (32) which annularly surrounds the run-in chamber (18) and which is delimited by an inner run-out chamber side wall, a base (33) and an outer run-out chamber side wall (34), wherein the run-out opening (25) is formed on the delimitation of the run-out chamber (32) and wherein the outer run-out chamber side wall (34) is designed as a spillway (38).

A feedwell comprising a plurality of holes disposed in a bottom thereof, at least some of the holes having a tube disposed thereabout which extends downward or otherwise away from an interior of the feedwell. Optionally, a large center hole can be provided and it can have a tube disposed around it. By providing a plurality of holes spread across a large portion of the bottom of the feedwell, lower velocity flow rates from the feedwell to a sedimentation chamber can be provided, thus reducing induced turbulence in the fluid within the sedimentation chamber, while still providing sufficient separation of the feedwell from the sedimentation chamber so that the contents of the feedwell can be properly and adequately mixed.

A cyclonic inlet diverter for initiating the separation of a multi-phase inlet fluid flow comprises an enclosed tubular body mounted crosswise within a larger separator vessel. The inlet diverter includes a splitter plate positioned within a center portion of the tubular body and configured to split the inlet flow into a first stream and a second stream, and a swirl plate positioned on each side of the splitter plate with angled surfaces configured to increase the cyclonic motion of the first and second streams within the tubular body. The inlet diverter further includes elongate apertures formed through bottom sidewall portions of the tubular body on each side of the splitter plate, an axial aperture formed through opposing end caps of the tubular body, and at least one radial aperture formed through lateral sidewall portions of the tubular body proximate each opposing end cap.

An extrusion system for separating particulates entrained in wash water, e.g. from harvesting tuberous produce, includes a settling tank configured to receive a flow of particulated water. A diffuser suspended within the tank converts the flow of particulated water into multiple transverse flows to avoid churning settled particulates. A particulate filter fixed within the tank includes a central channel surrounded by a cylindrical array of cantilevered parallel vertical blades. The channel directs the flows below the blades, causing dynamic movement of the blades as the particulated water rises therebetween to trap particulates along boundary layers, promote particulate settling by gravity, and allow clarified water to rise to the top of the tank. A sensor detects settled particulate reaching a predetermined setpoint, and in response the system actuates an auger and opens a pinch valve to force concentrated particulate from the bottom of the tank.

The disclosure provides a sewage treatment device and method for a thermal desorption system. The device comprises the thermal desorption system and a sewage treatment assembly connected with the thermal desorption system. The sewage treatment assembly comprises a particle precipitation tank for removing large particle suspended matters in sewage, a chemical purification tank for removing organic mattes in sewage and a filter tank for removing fine suspended matters in sewage, which are connected in turn, the particle precipitation tank comprises a stirring cavity provided with a stirring mechanism and a contaminant collection cavity, and the stirring mechanism comprises a stirring shaft provided with several groups of stirring blades along a length direction and a first motor driving the stirring shaft to rotate.

A method and apparatus for the separation of gas and liquid-solid slurry under pressure, and passage of the liquid-solid slurry to an atmospheric discharge.

A method, system, and apparatus directed to an innovative approach for the treatment of stormwater utilizing hydrodynamic separator assembly designed to maximize flow movement for more efficient sediment removal and maximize water flow control.

The system for a continuous dewatering recirculating for removing particulate such as coal combustion residue from a water stream. The system includes multiple dewatering and recirculation containers, each having a submerged flight conveyor and lamella settlings plate located therein, at least one dewatering and recirculation container receives ash water stream overflow.

A floating liquid intake for a liquid suction removal system, the liquid intake comprising housing defining an internal cavity. The housing has a hollow and buoyant annular body, an upper cover and a lower cover. The internal cavity is formed between the upper and lower covers. A substantially annular inlet is formed in the annular body for ingress of liquid into the cavity. The annular body has a buoyancy sufficient for the liquid intake to float in a liquid with the annular inlet submerged below the surface of the liquid in which the liquid intake is floating. A pipe extends into the cavity and the pipe includes an inlet that in use is open below the surface of the liquid within the cavity. The pipe extends outside of the cavity for connection to a liquid suction removal system.

A compact hydraulic particle separator apparatus is disclosed. The disclosed apparatus comprises an upper chamber and a lower chamber separated by a partition. A liquid fluid flow upwelling through the partition from the lower chamber is caused to mix with tangential jet of fluid flowing introduced above the partition in the upper chamber produces an upwardly-flowing cyclonic flow within the upper chamber. Particle mixtures containing low- and high-density particles and other solids are introduced into the upper chamber through a feed tube having a mouth that is offset from the center of the upper chamber. Low-density particles are immediately entrained in the cyclonic flow and swept upward and exit the apparatus.
