A split case adapted to hold water filtration units in a water filtration subassembly. The interior of the case holds three water filtration units arranged in series. The filtration units are in fluid communication with each other through fluid connectors. The assembly includes a water input member and a water output member, each generally positioned at opposing ends of the split case, each partially exposed to the space outside the case through apertures in the walls of the split case, and each providing fluid communication between the outside world and the water filtration subassembly.

A combined hopper and shaker assembly which can be used at least in processing excavation or other remains. The assembly features a hopper that can be pivoted (through operation of a hoist/sling) to cause the contents of the hopper to be fed via gravity through an exit chute onto the shaker. The hopper includes splash guards or sidewalls on the portions thereof that are proximate the pivot axis and an internal shape along the exit chute so as to guide the contents of the hopper toward the exit chute.

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.

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.

Methods, apparatuses and systems for filtering dewatered water utilizing primary and secondary containment mechanisms positioned on a portable sled, the primary containment mechanism of the system being a filter bag enclosed by an interior porous fence, the secondary containment mechanism including a filter medium positioned within a channel defined by the interior fence and an exterior porous fence and enclosing the filter bag. Water entering the filter bag exits the bag as filtrate which passes through the secondary containment mechanism and returns to the environment. The system is transported to a different location where filtering may continue utilizing the same filter bag enclosed within the interior fence.

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 filter system for filtering solids includes a filtration tank for receiving a slurry containing the solids to be filtered. A filter assembly including a plurality of filter cells each having a filter medium at an exterior and a cavity at an interior is lowered into the filtration tank using a transport device carrying the filter assembly. A vacuum transfer system is connected to the filter assembly so as to transfer a vacuum to an interior of the filter cells. The vacuum transfer system is operable to perform the filtering and to retain the filtered solids while the transport device moves the filter assembly relative to the filtration tank.

A magnetic particle carrier fluid recovery system includes at least one filter and a fluorescence reducer in fluid communication with contaminated magnetic particle carrier fluid. The filter(s) removes particulate matter less than 1 micron in size. The fluorescence reducer removes soluble fluorescent compounds from the carrier fluid causing background fluorescence contamination. A pump circulates the carrier fluid from a reservoir of contaminated fluid, through the system, and back to the reservoir. A cleaning loop runs the carrier fluid through the filter(s) and fluorescence reducer to remove contaminants to levels acceptable for new magnetic particle carrier fluid. A testing loop may be included that bypasses the filter(s) and fluorescence reducer. A valve may be actuated to toggle between the testing loop and cleaning loop for selective cleaning or use of the carrier fluid for MPI testing. The system may be integrated with an MPI station or may be independent and mobile.

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.
