A main housing provides a first reservoir and a second reservoir. Water flows from the first reservoir to the second reservoir. A draining aperture in the first reservoir directs water from the first reservoir to the second reservoir. The water may be flushed from the first reservoir to the second reservoir. In another embodiment, the water may flow directly from the first tank to the second tank without the flush. A pump circulates water from the second reservoir to the first reservoir. The pump directs the water through a filtration system to filter the water to remove at least some of the dirt, debris, and other contaminants from the water. The filtered water is then returned to the first reservoir. An overflow relief in a dividing wall of the first reservoir directs overflow water to the second reservoir.

A method for filtering solids from a slurry includes placing a filter assembly into a filtration tank containing the slurry. The filter assembly includes a plurality of filter cells each having a filter medium at an exterior and a cavity at an interior. The solids are filtered by moving the slurry through the filter mediums into the interiors of the filter cells to form a filter cake at the exteriors of the filter cells. The filter assembly is moved while applying a vacuum to the interiors of the filter cells through a vacuum transfer system including a mobile part and a stationary part. The mobile part moves along with the filter assembly and is sealed with respect to the stationary part.

A mechanism for detecting obstacles and mechanically reversing (a direction of) a pool cleaner includes a drive part in non-rotatable connection with a cleaner housing, an arresting assembly connected to the cleaner housing, and a rotary direction-changing assembly rotatably connected to the cleaner housing or the drive part. The arresting assembly cooperates with the rotary direction-changing assembly. The mechanism for detecting obstacles and mechanically reversing (a direction of) a pool cleaner is compact in structure, low in manufacturing cost, and can perform obstacle detection and change a direction of the pool cleaner. With the structure of the rotary direction-changing assembly capable of rotating relative to the cleaner housing, the cleaner, when meeting an obstacle, is allowed to change the traveling direction, thereby resulting in a high working efficiency.

Described herein is a method for cleaning an electrocoating bath in a continuous facility, where a skid connected to a conveying installation is conveyed through the electrocoating bath, and where the skid includes a filter medium; the filter medium is secured on the skid via at least one movable connecting element; the movable connecting element allows the orientation of the filter medium at the interface between electrocoating bath and air; and, after immersion of the skid into the electrocoating bath, during the conveying of the skid through the electrocoating bath, the filter medium is oriented at the interface between electrocoating bath and air and is drawn along the surface of the electrocoating bath. Also described herein is a skid for use in the cleaning method.

A bearing housing assembly featuring a bearing housing having a bearing housing wall portion with a bearing assembly chamber for receiving a bearing assembly and a shaft to be rotated, an oil sump for receiving and containing oil for lubricating the bearing assembly when the shaft is rotated, an oil path channel formed as an oil path for receiving dirty oil from the bearing assembly chamber for traveling down the oil path, and a filter assembly wall portion forming a filter assembly cavity coupled fluidically between the oil sump and the oil path channel; and a filter assembly arranged in the filter assembly cavity, to couple to the filter assembly wall portion, receive the dirty oil traveling down the oil path, filter the dirty oil and provide filtered oil to the oil sump, so the filtered oil can be recirculated to lubricate the bearing assembly when the shaft is rotated.

A mobile oil filtration system includes a mobile oil reservoir having a plurality of wheels; a housing secured to the mobile oil reservoir; an input conduit secured to the housing; a pump in fluid communication with the input conduit; a spring-loaded filter downstream from and in fluid communication with the pump; a bag filter downstream from and in fluid communication with the spring-loaded filter; and an output conduit secured to the housing and in fluid communication with the bag filter.

Methods, apparatuses and systems for treating liquid utilizing primary and secondary treatment mechanisms positioned on a portable sled, the primary treatment mechanism of the system being a filter bag used in conjunction with a secondary treatment mechanism including a straw bale layer positioned on a base of the sled. Liquid entering the filter bag exits the bag as filtrate which passes through the secondary treatment mechanism and flows by gravity to the environment. The system is transportable to different locations where filtering may continue utilizing the same filter bag. The filter bag is flexible and removable via a porous lift frame positioned below the filter bag.

A lint collection assembly for a dryer appliance includes a filter housing defining an aperture through which a flow of air exits the drying chamber. A roller assembly includes a supply roller for unrolling clean filter medium over the aperture and a collection roller for simultaneously receiving a used section of the filter medium. A drive mechanism, such as an electric motor is coupled directly to the collection roller or to a separate drive roller for moving the filter medium over the aperture between drying cycles to automatically and conveniently collect filtered lint.
