A waste treatment device may include a solid-liquid separator which is configured to receive and separate waste into solids and liquid. The waste treatment device may further include a solids treatment arrangement which is configured to receive the solids from the solid-liquid separator, wherein the solids treatment arrangement comprises a disinfection unit having a heating mechanism configured to heat, without burning, the solids so as to disinfect the solids to convert the solids into pathogen-free-treated-solids. The waste treatment device may further include a liquid treatment arrangement which is configured to receive the liquid from the solid- liquid separator and to treat the liquid so as to convert the liquid into pathogen-free-effluent. The solid-liquid separator may include a curved-funnel-shaped inner separator surface and a frusto conically-shaped inner liquid guide surface whereby the respective narrower ends are directed towards each other.

The present invention relates to an apparatus and a method of cleaning particle loaded "dirty" air using a multi flow- splitter technology in combination with at least one cyclone system which requires minimal energy to operate due to low pressure drops used to generate the fluid flows whilst allowing to exert high centrifugal or G-Force on the infeed fluid stream. This further allows to operate the particle removal process such that conventional additional filter media become optional, such that the technology may operate a significantly reduced or even without the need for maintenance and/or repair. Low internal air turbulence ensures a very high separation efficiency. Optionally adding additional explosion safe low-energy down-stream filtration stages with variable speed system fan provides optimal operational performance and operational flexibility.

An inertial dust separator comprises a plate, a pair of walls depending from the plate, and a curved wall connecting pair of walls. The plate is generally planar. The pair of walls are generally planar parallel walls depending generally normally from the generally planar plate. The curved wall has a first end, a second end, a first side edge and a second side edge and connects the pair of generally planar parallel walls. The curved wall is generally flat from side edge to side edge and curved from first end to second end. The first side edge and the second side edge connect generally normally to the pair of parallel generally planar walls. A portion of the curved wall adjacent the first end is generally parallel to the generally planar plate, and a portion of the curved wall adjacent to the second end is positioned at an angle in the range of about 100 to about 150 degrees with respect to the generally planar plate. The curved wall follows part of a generally circular path along the pair of generally planar walls.

A system and method are provided for producing from a first fluid having particles of a substance suspended or dissolved therein with a first concentration of the substance, a second fluid having a second concentration of the substance lower than the first concentration and a separated-fluid product, in which concentration of the substance is greater than that in the first fluid. The system comprises a pre-treatment module for processing the first fluid to produce aggregates from the substance and at least one separation duct in fluid communication with an outlet of the pre-treatment module, the duct having at least one bay portion having such design as to cause aggregates to accumulate along a pre-determined wall of the bay portion, thereby facilitating separation between the second fluid and the separated-fluid product.

Methods and apparatus for processing a material, the material being the upper layer from a metal melting process, the material containing one or more salts, the material containing one or metals, are provided. The method includes feeding the material to a size reduction step; feeding the material from the size reduction step to a density based separation step; feeding the material from the density based separation step to a leaching step. The size reduction stage is optimised to provide exposure of material for a ferrous and non-ferrous metal separation. The ferrous separation is preferably provided by an eddy current separator. The non-ferrous separation is preferably provided by a cyclone.

A device for washing a suspension of cells. The device includes a bowl-shaped basin having a top end and a bottom end and an axis extending from the top end to the bottom end, and an inlet port formed in the basin. The inlet port is positioned at an angle to allow for a wash solution to be injected or delivered into the basin and circulate around the basin about the central axis. A suspension of cells can be washed in the circulating wash solution. The circulating wash solution forces the cells to settle at the bottom of the basin, where they can be extracted.

The present invention relates to an arrangement and method for separating harmful material, especially sand, from a liquid stream or a low-consistency fibre suspension in a pulp production process. The arrangement comprises a cyclone-type separator comprising a vertical chamber, in the upper part of which a tangential inlet is arranged for creating a swirling motion for the stream to be cleaned, and an accept outlet, the conical lower part of which separator is provided with a reject outlet. The arrangement comprises two or more cyclone-type separators (301) that are connected in parallel, whereby their inlets open into at least one feed channel (310) having at least one inlet, and their accept outlet open into a common discharge channel (313) having at least one outlet, and their reject outlets open into a common discharge channel having at least one outlet that is connected to at least one auxiliary separator (316) having conduits (318, 319 ) for discharge of accept and reject.

The present invention provides methods and means for separating slurry liquid from catalyst in a three-phase slurry process. The embodiments of the invention are characterized by conducting the three-phase process under conditions to provide an upper region in the slurry that contains a catalyst concentration of about 20 wt% or less and a lower region with a catalyst concentration higher than about 20 wt%. A portion of the slurry in this upper region is degassed and passed to liquid-solid separation devices for recovery of liquid product.

Die erfindungsgemäße Vorrichtung zur Separierung von einem Feststoff und einem Gas besteht im Wesentlichen aus einer wendel- und/oder spiralartigen Leitung, in der durch Zentrifugalkräfte eine Gas-Feststoff-Suspension in einen Feststrom und einen Gasstrom getrennt werden und einer mit dem Ende der wendel- und/oder spiralartigen Leitung in Verbindung stehenden Abscheidekammer, an die eine Feststoffleitung zum Ableiten des Feststoffstroms und eine Gasleitung zum Ableiten des Gasstroms angeschlossen sind.
