A water purification kit/system comprises a first pot, a second pot, a filter, and a condensation collector. The first pot and the second pot are configurable into first and second configurations, wherein, in the first and second configurations, the first pot is either an upper pot or a lower pot, and the second pot is the other of the upper pot and the lower pot. In the first configuration, the upper pot and the lower pot form a water filtration system. In the second configuration, the upper pot and the lower pot form a water distillation system.

Provided are a filter cloth recovery device and a copper rod continuous casting and rolling manufacturing system using the same. This device includes a cleaning water tank, a winding mechanism and a cleaning mechanism provided on the cleaning water tank. The winding mechanism includes: a winding shaft provided on the cleaning water tank for winding a filter cloth after being cleaned; a first guiding roller for guiding a filter cloth to be cleaned into a cloth-transmitting path within the cleaning water tank; and a second guiding roller between the first guiding roller and the winding shaft along the cloth-transmitting path for providing a tension force to the filter cloth. One end of the winding shaft is connected with a driving mechanism. The cleaning mechanism is provided with multiple liquid spraying openings for spraying a cleaning fluid to the filter cloth located in the cloth-transmitting path during winding.

A particle separation system may comprise a vessel having at least one side wall and a bottom wall forming an internal chamber within the vessel, a filtration unit positioned within the vessel and including a first filtration pack including a first plurality of filter elements, an inlet for moving pre-separated fluid into the vessel, and an outlet in fluid communication with the filtration pack for moving processed fluid out of the vessel, a rate of pre-separated fluid flow into the vessel and a rate of processed fluid flow out of the vessel each being between about 10 and about 1000 gallons per minute (GPM) and a flux within the filtration unit is less than or equal to about 0.05 gallons per minute per square foot (GPM/ft.sup.2).

A stormwater runoff treatment system that offers an economical means of achieving highly efficient, effective, and compact means of treating runoff through a unique method of flow restrictions, diversions, elevation differences and strategically located components to achieve a combination of treatment advantages.

A fuel filter includes: a casing having a chamber for collecting water separated from fuel; a water level sensor that extends into the casing and is provided with an electrical water level contact extending into the collection chamber and an intermediate electrical contact arranged inside the casing and outside the collection chamber; and a water separator element having: a filtering element; a filtering element support provided with a through opening crossed by the water level sensor so that the electrical water level contact extends into the collection chamber; and a conductive element provided on the filtering element support and provided with: a water level electrode extending into the collection chamber; and a contact electrode electrically connected with the water level electrode, spaced apart from it and in contact with the intermediate electrical contact of the water level sensor.

A dip tank and recycling system for applying antimicrobial solution to food items, including a dip tank having a bottom and sides, and holding a liquid antimicrobial solution. A conveyor to convey food items through the tank passes through the liquid antimicrobial solution held in the tank such that food items conveyed on the conveyor are dipped in the liquid antimicrobial solution. At least two discharge nozzles spray fresh antimicrobial solution into the tank. The discharge nozzles are located in the sides of the tank, and are positioned above the level of the conveyor but below an expected top level of the liquid antimicrobial solution contained within the tank such that food items conveyed on the conveyor are agitated by the force of the spray from the discharge nozzles. The spray from the discharge nozzles causes unstacking of items on the conveyor, producing an even application of the antimicrobial solution.

A dewatering system is disclosed. In a particular embodiment, the dewatering system includes a debris tank configured to receive a slurry through an inlet and a dewatering filter installed in the debris tank. In addition, the dewatering system includes a bar screen forming a curvilinear surface of the dewatering filter, where the bar screen is configured to prevent sediment from passing through and into an interior space of the dewatering filter. A first end of the dewatering filter is in communication with a discharge port to remove filtered liquid from an interior of the debris tank, and a vibratory device is configured to shake the dewatering filter to remove sediment from an exterior surface of the dewatering filter.

Filtration systems having a normal filtration mode and an enhanced filtration mode are described. In some arrangements, the filtration system is an air filtration system having a primary air filter element, a pre-cleaner, and a pre-cleaner bypass valve. Based on feedback from an intake air quality sensor the bypass valve is either opened or closed to selectively route intake air through the pre-cleaner during sensed dirty air operating conditions (e.g., heavy dust or moisture concentrations). In other arrangements, the filtration system is a liquid filtration system (e.g., a fuel or oil a secondary filter. The filtration system selectively routes the liquid being filtered through the main filter, the secondary filter, or a combination thereof depending on a detected event or sensed characteristic of the liquid.

A fluid reservoir for accommodating a fluid reductant used in an SCR exhaust treatment process may include various styles or designs of bag filters to filter debris and contaminants from the reductant prior to being channeled out of the reservoir. To secure the bag filter to a header assembly accommodating the various inlet and outlet tubes, in one aspect, the bag filter is adapted to fit around a header boss descending from the header assembly and protruding into the reservoir volume. Various configurations for the bag filter can be utilized to secure the bag filter to the header boss in a manner that isolates the tubes of the header assembly from the remainder of the reservoir volume to prevent debris and the like from being unintentionally drawn out of the reservoir.

A filter element (10) has a filter bellows (12) arranged about the longitudinal axis (L) and having a first end disk (14) on a first end face (26), and a second end disk (16) on a second end face (28). A central element (20) is arranged rotatably about the longitudinal axis (L) relative to the filter bellows (12) in the interior (18) of the filter bellows (12). The central element (20) has one or multiple positioning elements (22, 24) which interact with counter positioning elements (116, 118) of an upper housing part (114) to fix the central element in the upper housing part (114) in a defined angular position. The central element (20) has at least one electrical connector element (32) on the element, electrically contacting at least one electrical connector element (120) on the housing.
