A device includes a compartment for separating the solids and liquids. The compartment includes a base that is concavely curved according to a cylindrical portion having a transverse axis and is formed of a sieve, an idler roller mounted transversely on an arm, a drive which actuates the arm, and resilient means for adjusting the pressure exerted by the rollers. Both the contact interface between the sieve and the roller and the rotational interface between the roller and the arm are made of a non-metal material on at least one of the two contacting surfaces that form each of the interfaces, such that, there is no metal-on-metal contact between surfaces moving relative to one another at the interfaces.

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.

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.

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.

Provided by the present invention is a faucet water purifier for filtering a raw water, which comprises a control valve and a filtering device, wherein the filtering device defines a first communicating opening and a second communicating opening, the control valve comprises a valve body and a valve core, wherein the valve body defines a valve cavity, a first opening, a second opening, a third opening, a raw water inlet and a draining opening, wherein the valve core is disposed inside the valve cavity, wherein the first opening is communicated with the first communicating opening of the filtering device, the second opening is communicated with the second communicating opening of the filtering device, the third opening is communicated with a water outlet of the filtering device, and the raw water inlet of the valve body is adapted to be communicated with a raw water source.

A filtration device efficiently sizes removal of unnecessary substances adhering to and deposited on a filter medium of a filter element during filtration and backwashing (cleaning) from target (non-filtered) substances. The filter element captures substances in a fluid on one surface of a filter medium. The captured substances are separated from the filter medium during backwashing. A brush moves relative to the one surface of the filter medium and assists in separating the captured substances and sifting during the relative movement. The backwashing starts when a differential pressure between both surfaces of the filter medium exceeds a predetermined value, or the like while performing the filtration, and returns to filtration after the differential pressure is eliminated or after a predetermined time elapses. The brush sifts the unnecessary substances from the captured substances and passes the removal to the other surface side during the filtration.

The present disclosure relates to a separation device to separate contaminants from contaminated water. It comprises a container to receive the contaminated water. The container further comprises a contaminated water inlet, a filter, a presser for compressing and/or dewatering contaminants separated from the contaminated water, and a contaminant outlet. The container further comprises a gas inlet for generating gas bubbles into the contaminated water to further separate contaminants from the contaminated water. The present disclosure relates to a use of such a separation device and a method of separating contaminants from contaminated water.

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 microplastic filter (also referred herein as fluid filter) for a washing machine has a filter housing, a first filter screen, a second filter screen, an inlet opening 16, and an outlet opening. The inlet and outlet openings communicate with each other through the first filter screen to define a direction of fluid flow. The first filter chamber has a retentate outlet, is particularly easy to handle if the second filter screen is arranged in a cavity of the filter housing, the inlet and outlet openings communicate with each other through the second filter screen, and the retentate outlet is arranged on a side of the second filter screen that faces the fluid flow.

A dishwasher appliance includes a filter assembly positioned between a pump and a spray body along a flow path between the pump and the spray body. The filter assembly includes a cylindrical filter medium positioned within a housing proximate an inlet of the housing. A plurality of vanes is distributed around the cylindrical filter medium. The plurality of vanes is rotatable about the cylindrical filter medium.
