A filtering module includes a cyclone having a contaminated air inlet part into which external contaminated air and cleaning water cleaning the contaminated air are each introduced, and a cleaned air outlet part through which air cleaned by bringing the cleaning water into contact with the contaminated air is discharged; a water tank coupled to the cyclone, to which the cleaning water cleaning the contaminated air is introduced, and storing mixed water in which a pre-stored fluid and the cleaning water are mixed; and a fluid circulating part providing the mixed water stored in the water tank to the contaminated air inlet part.

A drinking water treatment system is disclosed. The system includes an ultraviolet (UV) light source and an adsorption medium positioned downstream of the UV light source. The UV light activates residual chlorine in water. The adsorption medium is configured to adsorb any remaining free chlorine from the water. Drinking water treatment systems are disclosed for point-of-use (POU) applications, such as tap-mounted countertop, under-counter, and/or commercial bottling applications, and for point-of-entry (POE).

An F.O.G. separation apparatus includes a tank for receiving a liquid effluent flow containing water, F.O.G., and gross solids. The tank has a chamber, an inlet in an inlet module, a downstream section and an outlet in an outlet module. The inlet module has a weir for the effluent downstream of a strainer to strain gross solids from the effluent. A pump upstream of the strainer pumps water and solids that do not pass through the strainer. The pump's rotatable vertical shaft has a motor at an upper and an impeller at the bottom. A pipe connected to the inlet module near the impeller conveys solids and water when the pump is activated and directs the solids and water to the outlet. F.O.G. and water entering the tank pass to the downstream section where the F.O.G. is removed from the water by a skimmer, and the residual water exist the tank through the outlet module.

The subject matter of the invention is a filter element (13) for insertion into a vacuum cleaner, with an upper side (14), a lower side (15) which lies opposite the upper side (14), a filter body (19) which extends from the upper side (14) to the lower side (15) and which forms a wall (26) of a clean air space which is situated between the upper side and the lower side, and with a conveying opening (17) which is arranged on the upper side (14), opens into the clean air space, and through which an air flow which is driven by way of the vacuum cleaner can be conveyed. According to the invention, a deflecting surface (20) which extends in the direction of the lower side (15) is arranged in the clean air space below the conveying opening (17), which deflecting surface (20) is configured to deflect an air flow which is introduced through the conveying opening (17) in the direction of the wall (26) of the clean air space. The filter element (13) according to the invention can be relieved of filter cakes in a simple and effective way.

An eco-friendly water filtration apparatus. The apparatus may comprise a lid comprising openings that allow water to flow into the apparatus, and an enclosure that is open at one end and comprises openings at the opposing end that allow water to flow out of the apparatus. The enclosure may be configured to receive a pod of activated carbon, while allowing removal of the pod, and the lid may be configured to attach to and detach from the enclosure at the enclosure's open end.

A container-type apparatus for wastewater treatment with a suspended particle system, including one or multiple biological reaction zones. The biological reaction zones can be facultative, anaerobic, anoxic, and aerobic and at least one of the biological reaction zones is a suspended particle system. Particles in the suspended particle system act as the carrier of microbiota and offer better conditions for them to grow. The apparatus adopts a box structure, such as a container type, which is convenient to move, flexible to assemble, and can be used multiple times. Based on actual requirements, this apparatus can also be a structure type. The suspended particle system can increase the concentration of microorganisms significantly, improve the ability to bear impact load, produce less sludge, and without sludge expansion.

The present invention relates to a removal device for removing gas bubbles and/or dirt particles from a liquid in a liquid conduit system or for removing a second liquid from a first liquid in the conduit system. The removal device includes a main channel for a main flow, the main channel having an entry and an exit which are configured to be connected to the conduit system, a housing which defines an inner space, at least one supply channel extending from the main channel to the inner space, at least one return channel extending from the inner space back to the main channel, directly or indirectly via a return chamber, at least one quiet zone in the inner space in which in use the liquid has a substantially smaller velocity than in the main channel. The quiet zone is configured to allow dirt particles or a relatively heavy liquid to settle at a lower end of the housing and/or gas bubbles or a relatively light liquid to rise to an upper end of the housing. The removal device further comprises means to remove dirt particles or relatively heavy liquid, and/or gas or relatively light liquid out of the housing.

A handheld air purifier may include a suction body provided with a fan to suction air and a filter to filter foreign matter from the sucked air, a handle extending from the suction body, and an agitator provided in the suction body to loosen or scatter dust from a garment. The handheld air purifier may be configured to be attached to and detached from a main air purifier, and the main air purifier may suction dust off the handheld air purifier and sterilize the handheld air purifier when the handheld air purifier is mounted on the main air purifier. The agitator of the handheld air purifier may have a striking member exposed through a lower surface of the suction body, and may move out of and into the suction body to strike the garment so that the dust may be loosened and suctioned into the suction body and filtered by the filter.

A telescopic fitment for connection of a magnetic filter into a central heating system circuit includes a first connector and a second connector, each of the first and second connectors including a filter connection end for connecting with the magnetic filter and a circuit connection end for connecting with the central heating system circuit, at least one of the first and second connectors including an inner pipe and an outer pipe, the filter connection end being provided on one of the inner or outer pipes and the circuit connection end being provided on the other of the inner or outer pipes, the inner pipe being slideable within the outer pipe for adjusting the position of the circuit connection end with respect to the filter connection end, whilst maintaining a sealed fluid path between the circuit connection end and the filter connection end.

A magnetic debris level measuring device for a magnetic filter is disclosed. The magnetic debris level measuring device includes a magnetometer and a temperature sensor. The temperature measured by the temperature sensor is used to calculate a corrected magnetometer reading, which in turn can be used to determine the amount of captured magnetic debris held within the filter. The device has a stored threshold for the corrected magnetometer reading, and when the corrected magnetometer reading crosses the stored threshold a notification is issued that the filter is full. If it is detected that debris continues to be captured after the full notification has been issued, the stored threshold will be updated accordingly.
