A device for extracorporeal blood treatment, in particular a dialysis device, including an internal fluidic system for a treatment liquid, in particular for a dialysis liquid, the internal fluidic system having at least two liquid connectors for connecting a substantially cylindrical filter element, in particular a dialyzer, to the internal fluidic system for passing a treatment liquid through the filter element, and including a mounting for exchangeably holding the filter element in such a way that the filter element can be connected to the liquid connectors of the internal fluidic system and to an extracorporeal blood line in an intended manner, wherein the mounting for holding the filter element is designed in such a way that a cylinder longitudinal axis of the filter element is substantially horizontally aligned.

Exemplary systems and methods relating to washboxes are described.

An apparatus for removing impurities from water and/or wastewater and a method of installing a fluid distribution system in the apparatus. In the most preferred form of the invention, the fluid distribution system is an air scour system for directing air through the filter bed to assist in cleaning of the filter bed to remove impurities trapped in the filter bed during a service run. In the most preferred form, the method of installing the fluid distribution system in the filter bed is performed by imparting a force to the filter bed to permit the fluid distribution system to be installed in the filter bed without removing media. The fluid distribution system is preferably configured to permit the fluid distribution system to be readily installed in the filter bed and at an optimum orientation.

An imaging system includes a housing to define a housing space, a collection device to collect fine particles in the housing space, a detection device to detect a collection performance of the collection device, and a cleaning device to clean the collection device.

A contact chamber in which a bed of fluid treatment media is fully fluidized by using a fluidizer. The fluidizer may be, for example, an internal or external eductor that acts as a pump for a media and fluid mixture to boost fluid flow and generate recirculation that keeps the media suspended in the fluid or an arrangement of nozzles, mixing blades, pumps, baffles, or irregular cross-sectional shapes (or combinations of any of these) to promote fully fluidizing the media in the chamber and causing the media to recirculate within the chamber.

A floating media filter including a filter housing with an influent conduit extending into the filter housing, the influent conduit having at least one outflow aperture positioned below an effluent outlet of the filter housing. A floating media is positioned in the filter housing and forms a media bed when the filter is in a filtration stage, the media bed having a lower surface and an upper surface defining a filtration zone between the lower and upper media bed surfaces during the filtration stage. A diffuser trough is positioned in the filter housing such that (i) the lower surface of the media bed, when the filter is in the filtration stage, is below an upper edge of the diffuser trough, and (ii) the outflow aperture of the influent conduit is positioned sufficiently close to a surface of the diffuser trough such that influent flow, during the filtration stage, is initially directed against and/or along the surface of the diffuser trough, and then redirected in a path into the media bed. Finally, the media filter includes a backwashing mechanism causing (i) lowering of the upper surface of the media bed to a point below the upper edge of the diffuser trough, and (ii) creation of an air space in a substantial portion of the filtration zone.

A filter structure has a main body and a stirring member. The main body has a hollow containment space filled with a filtering material. A filtering mesh is disposed at a bottom side of the containment space. A first purifying opening is disposed at a top end of the main body. A second purifying opening is disposed at a lower sidewall position of the main body above the filtering mesh. A first cleaning opening and a second cleaning opening are disposed on the main body and respectively coupled to a first and second inner pipe. An outlet is disposed at a bottom of the main body. The stirring member has an upper cover corresponding to the first purifying opening of the main body. The upper cover further has a driving arm and a connecting rod, and the connecting rod has a plurality of stirring rods.
