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.

The present invention provides an apparatus for feeding a feed slurry into a particle separator having a fluidisation source. The feed apparatus comprises a chamber having at least one baffle for dividing the chamber into a first zone and a second zone. A feed inlet feeds the slurry into the first zone (20) and the baffle deflects the slurry away from the second zone and direct fluidisation fluid from the fluidisation source through the second zone to combine with the slurry from the first zone. A particle separator incorporating the feed apparatus and a method of particle separation is also provided.

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.

Various examples are provided for systems and apparatus for separation of particulate matter from fluid. In one example, an apparatus has a first wall and a second wall connected to and separated by an end edge wall and one or more side edge walls. The first wall has a fluid outlet. The apparatus has a separation chamber with a volume defined by the first wall, the second wall, the end edge wall, and the one or more side edge walls. Each of the side edge walls extends from a respective end of the end edge wall. The side edge walls taper from the end edge wall to a fluid exchange port, to guide contaminants or other particulate matter out the fluid exchange port.

The disclosure relates to an installation for processing and/or using process liquid, comprising at least one first installation section which comprises at least one heat exchanger for heating the process liquid. The heated process liquid can be guided directly or indirectly to a second installation section for processing and/or use. The invention is directed to the problem of providing an installation by means of which the wear and tear of comminution mechanisms, in particular for frozen, cold or tough biomass, can be reduced in a cost-effective and environmentally friendly manner. The installation is characterized in that the second installation section comprises at least one washing, soaking and/or thawing booth device for treating biomass using the warm process liquid.

An apparatus and methods for the separation of macroscopic solid body particles (SBPs) from a fluid stream contained in a conduit, such as a hose or pipe. The method involves utilizing a particle separator having a fluid inlet port connected to a fluid inlet conduit and a fluid outlet port connected to a fluid outlet conduit to change the direction (and optionally the velocity) of the fluid stream within a lumen of an enclosed vessel component of the particle separator sufficiently to permit SBPs to fall by gravity (and/or to descend due to inertia) into a removable receptacle within a bottom portion of the vessel component while directing the flow of cleansed fluid to the fluid outlet port of the particle separator.

A carbon negative clean fuel production system includes: a main platform; a heat collection device for capturing heat from a hydrothermal emissions from a hydrothermal vent on a floor of an ocean; a heat-driven electric generator; a heat distribution system including a heat absorbing material and a heat transporting pipe; anchor platforms tethered to the main platform; a mineral separator; a seawater filtration unit; a water splitting device; a sand refinery machine; a carbon removal system; and a chemical production system for producing hydrides, halides and silane. Also disclosed is a method for carbon negative clean fuel production, including: capturing heat; producing electric energy; separating minerals; filtering seawater; splitting water; refining sand; removing carbon dioxide; and producing hydrides, halides, and silane.

A method for collecting mill scale from a hot rolling mill is provided. The hot rolling mill includes a flume. The method includes transporting mill scale particles in wastewater, retrieving the wastewater from a flume of the hot rolling mill and separating the mill scale particles from the wastewater using a separator. A hot rolling mill and a method for retrofitting a hot rolling mill are also provided.

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 feedwell design for a clarifier that may better dissipate the entrance energy of feed slurry liquid exiting the feedwell and entering the clarifier. Plates having a surface area twisted around a longitudinal axis may be provided at the bottom of the feedwell. The plates may cause a change in the flow direction of the feed, from being mostly horizontal to mostly vertical, to slow the slurry. The provision of plates at the bottom of a feedwell in a clarifier may advantageously reduce the velocity of the materials entering the clarifier, or may increase the uniformity of the flow rate of the materials while reducing or maintaining the amount of shear force, turbulence, or other forces that may have a detrimental effect on clarification. Likewise, this may improve the rate at which solids settle out of the feed slurry solution, and thus improve the clarity of the removed liquid.
