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.

An air washer includes an outer case having an air suction port, a water tub disposed in the outer case to store water, a humidification unit disposed in the water tub, a display unit disposed so as to be spaced apart from the outer case to form an air discharge port, the display unit having a water supply port, through which water is supplied, an inner case located at an upper side of the water tub, the inner case having an air channel, connecting the air suction port with the air discharge port, and a water channel, along which the water injected through the water supply port is guided to the water tub, and a blower disposed in the inner case to blow air suctioned through the air suction port to the air discharge port.

The present disclosure provides a container-type apparatus for wastewater treatment with a suspended particle system, including one or multiple biological reaction zones. Said biological reaction zones can be facultative, anaerobic, anoxic, and aerobic and at least one of said biological reaction zones is a suspended particle system. Particles in said 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 for multiple times. Based on actual requirements, this apparatus can also be a structure type. The suspended particle system disclosed herein applied in wastewater treatment can increase the concentration of microorganisms significantly, improve the ability to bear impact load, produce less sludge, and without sludge expansion. Meanwhile, the means to suspend particles by gas and liquid is able to reduce energy consumption to a larger extent. Therefore, this system features high efficiency and low energy consumption.

A filter device comprises a first filter mechanism and a second filter mechanism, the first filter mechanism is connected to the second filter mechanism, wherein the first filter is configured to filter disinfectants, impurities, and organic matters in water, and the second filter is configured to filter germs in the water. A faucet water purifier comprises above filter device.

Provided herein is a filter medium comprising a first nonwoven melt-blown layer, the meltblown nonwoven comprising a) at least one styrenic thermoplastic elastomer and b) at least one polyolefin. Also provided herein is the use of the filter medium for coffee filters, compressed air filters and face masks.

A water filter is provided. The water filter includes a filtration material and a filter housing spaced for accommodating at least a portion of the filtration material therein. The water filter also includes a housing cap coupled to an upper end of the filter housing for enclosing the filtration material within the water filter. The housing cap includes an upper portion, a lower portion, and a channel formed through the upper portion and the lower portion. The water filter also includes an interface adapter accommodated in the channel, wherein the interface adapter includes a side wall vertically extending from an upper surface of the interface adapter and partially around a perimeter of the upper surface, and a projection vertically extending from the upper surface, wherein the projection is integrally formed with the upper surface and a portion of the side wall.

A water faucet or water tap includes, in its base area or other suitable area or region, a built-in or embedded or integrated filtering mechanism. The filtering mechanism includes a nonelectrical filtering chamber, having a cavity for securing therein a replaceable water-filtering capsule. A suitable water-filtering capsule, having an active filtering component or a passive filtering component, is inserted into the non-electrical filtering chamber, and can be removed from it for periodical replacement. Optionally, the water-filtering capsule includes a scent-producing agent, a flavor-producing agent, or a nutrient or a supplement, which are added to the filtered water. Optionally, a bypass mechanism or water-diverting mechanism enables to select between: a first mode in which a first water-outlet outputs non-filtered mixed hot-and-cold water; and a second mode in which a second water-outlet outputs filtered cold water or filtered room-temperature water.

An integrated faucet filtration system comprising a faucet assembly; a filter assembly; a first T-connector; and a second T-connector; wherein, the faucet assembly comprises a body; a spout; a spray head; a multi-channel hose fluidly coupled to the spray head and disposed in the spout; and a valve cartridge configured to control flow of unfiltered water; the filter assembly comprises a water filter; an electronic actuator; and a solenoid valve; the first T-connecter comprises a first branch configured to receive unfiltered water from a water source; a second branch configured to deliver unfiltered water to the water filter; and a third branch configured to deliver unfiltered water to the valve cartridge; and the second T-connecter comprises a first branch configured to receive unfiltered water from the valve cartridge; a second branch configured to receive filtered water from the water filter; and a third branch configured to deliver the filtered and unfiltered water.

A separator device for removing particles from suspension in a liquid includes a housing having first and second chambers with apertures for ingress and egress of liquid into the first chamber. Means are provided for setting up a swirl of liquid within the first chamber. Apertures enable flow of liquid between the first chamber and the second chamber. Means are also provided for setting up a swirl of liquid within the second chamber. The swirl in the second chamber is in substantially the opposite direction to the swirl in the first chamber, and there is no substantial flow in the second chamber which is in the same direction as the swirl in the first chamber.
