A system for treating wash waste liquid is described, configured for coupling to a wash module of a continuous Tunnel washing machine for the field of Preclinical Pharmaceutical Research, said wash module (12) comprising a wash chamber (25), characterized in that it comprises: a wash tub (22) with a side wall (31) substantially cylindrical in shape, with a tangential liquid suction outlet (33) and a substantially conical bottom, with a wash waste drain point (35) at the vertex of the cone, said tangential suction being adapted to generate a rotational motion of the liquid in said tub, said tub being positioned under said wash chamber (25), so as to receive said wash liquid by gravity; a centrifugal wash pump (21) with an open impeller, adapted to take in liquid from said tangential liquid suction outlet (33); an in-line filter (26) with an internal filter cartridge of the wedge-wire type, adapted to filter the liquid coming from said centrifugal pump (21) and deliver it back, filtered, into said wash chamber (25), and comprising a flush valve (27) for discharging the filtering waste.

The present disclosure provides devices and methods for processing and harvesting adipose tissue. The present disclosure provides improved devices, systems, and methods for harvesting, processing, and filtering adipose tissue for autologous fat transfer procedures. The features of the devices and systems of the present disclosure increase efficiency and sterility of adipose tissue processing by reducing the need for users to interrupt the procedure to adjust some part of the system, such as unclogging filter pores or adjusting tubing.

The present invention discloses a method for self-cleaning filters without having to open the filter housing. Wash nozzles are integrated with the filter housings such that when the filters are clogged, both back-wash and regular washing can be performed with practically no down time. Moreover, without opening the filter housing, the hazardous components of the fluid to be filtered can be contained and dealt with before they escape the filter housing, thereby significantly reduces the environmental impact and harm to the working crew.

A filtering device for removing solids from water. Within the filtering device, water, under the force of gravity, flows through successive porous members. Plates are used to distribute the water prior to the water flowing through the porous members. Rotating brushes are used to removed retained solids from the porous members. The brushes are preferably returned to a home position when not being utilized to remove solids in which they are maintained out of contact with the porous members.

A nozzle for a filter cleaning system has a stub portion having an inlet opening and an outlet opening, and a splitter portion positioned downstream of the stub portion. The splitter portion has deflector surfaces arranged to direct the airflow exiting the stub portion outlet in 3 or more different/separate airstreams each of which airstreams are directed inclined axially outwardly from the axial direction of the airflow exiting the stub portion outlet opening. The various parameters of the splitter nozzle portion can be tailored to provide required jet shape and entrainment characteristics. A beneficial feature of the nozzle designs is that jet entrainment and recombination of flows can be specified for different shaped filters.

The present invention relates to a filter device with enhancements to ensure the continuity of the function of the flexible scraper element (23), which separates plastic and waste (pollution, foreign matter) from each other, presses on the filtering element to be used in recycling systems for the recovery of plastic materials, to enable the scraper to sharpen itself, to prevent permanent damage on the filtering element (9) due to the melt pressure.

A device for separating and lifting solids from waste water has a stationary drum provided with a first filter screen and a screw conveyor. An auger shaft has a lower portion located inside the stationary drum, which is partially surrounded by a second filter screen. The lower portion is connected to a cleaning apparatus of the first filter screen formed by a plurality of comb-holder arms mounted on a cross shaped element. The comb-holder arms are integral at the opposite end to an anti-skid ring sliding in a sliding seat integral with the support frame. Each comb-holder arm has an elongated comb facing the first filter screen and in contact with it. The comb-holder arms are connected to the auger shaft by means of an epicyclic secondary gear.

Apparatus for removing debris from channeled water that includes a bar screen assembly. The assembly includes a plurality of spaced apart screen bars, each bar having an upstream edge and a downstream edge and distal ends to which U-shaped clips are attached. Each of the clips has a bar engaging portion and a cross member engaging portion that attaches to an associated cross member. The clips operate to space the trailing edge of the screen bars a predetermined distance from associated cross members and allow easy replacement of a bar. A continuous conveyor carries a plurality of rakes having a plurality of spaced apart tines which are adapted to fit between the screen bars as the rake is moved along the bars by the conveyor. The tines of the rake have a length that substantially spans the distance between the leading edge and trailing edge of a bar, so that tips of the rake tines extend to at least the trailing edge of an associated bar. Intermediate clips may be used to support the intermediate section of the screen bars.

The subject matter of the invention is a nozzle-brush automatic cleaning filtration device with motor reducer performing physical cleaning by trapping coarse particles and suspended solid contents in any liquids. These filters perform physical cleaning by trapping coarse particles and suspended solid contents in any liquids.

A screening device for separating out and removing contaminants from wastewater includes two continuous conveyors, which are mounted with clearance from each other. Each has a drive wheel that is guided on a circular path and includes a fixedly situated bar screen, which includes multiple mutually spaced grating bars for removing contaminants from the wastewater. Each bar screen includes multiple clearing elements, which are connected to the conveyor for removing from the bar screen the contaminants that have been separated out by the bar screen. The bar screen forms a fixed screen surface that extends, in the intended installation position of the screening device, essentially in the flow direction of the wastewater reaching the screening device.
