A fluid filtration system is disclosed herein. The filtration system includes a main tubular housing defining an interior chamber and having an outlet opening at a top end thereof and an inlet opening at a bottom thereof. A tubular inlet housing extends vertically into the interior chamber of the main housing through the inlet opening of the main housing. The tubular inlet housing has a hollow interior filled with shards of permanent magnets, a plurality of outlet portals located in the interior chamber proximate the bottom of the main housing, and an inlet opening at a bottom thereof. An inlet conduit is connected to the inlet opening of the tubular inlet housing. An adjustable fluid pump and can force the fluid from a supply of fluid to be filtered upwards through the inlet conduit at varying speeds. A permeable but compact horizontal layer of medium capable of trapping particulates is provided in the interior chamber of the main tubular housing adjacent the tubular inlet housing. The layer includes filtering particles that are attached to the magnets. Forces of magnetism produced by the shards of permanent magnets and gravity constrain the horizontal layer of filtering medium to maintain in place the layer of filtering particles. The adjustable fluid pump, an air pump connected to the inlet conduit, or electromagnets or vibrators mounted on an outer surface of the main housing can be used to disrupt the compactness of the layer of filtering particles to permit trapped particulates to be released and washed away from the layer of filtering particles.

The present disclosure is directed to fluid filtering systems and methods for use during semiconductor processing. One or more embodiments are directed to fluid filtering systems and methods for filtering ions and particles from a fluid as the fluid is being provided to a semiconductor wafer processing tool, such as to a semiconductor wafer cleaning tool.

The instant invention, in one aspect, provides a process for decontaminating water to remove contaminants, said process comprising passing contaminated water through a filter comprising a plurality of filtering elements capable of lowering the contaminants by at least 70%. In another aspect is provides a filtering unit comprising a plurality of filtering elements arranged in individual layers, said individual layers independently selected from brick chips, hemp fibers, mixture of hemp fibers and charcoal, agave, jute fibers, sand, filter paper, and gravel.

A water softening device for use for a pet is provided, comprising: a first chamber having a shape of a hollow container; a second chamber having a shape of a hollow container, the second chamber being detachably attached to an upper section inside the first chamber; and a filter cartridge having a plurality of openings and containing an ion exchange resin therein, the filter cartridge being detachably attached to a bottom section of the second chamber and positioned to protrude from the bottom section of the second chamber to a lower section inside the first chamber. The second chamber is configured to receive and contain first water including tap water, and the lower section inside the first chamber is configured to receive and contain second water that is the first water after passing through the filter cartridge based on gravity.

A filtration system for a fuel cell hybrid propulsion system includes a first stage filter, a second stage filter positioned downstream of the first stage filter, and a third stage filter positioned downstream of the second stage filter and configured to be positioned upstream of a fuel cell system. The first stage filter has first pores with a first mean pore size. The second stage filter has second pores with a second mean pore size. The third stage filter has third pores with a third mean pore size. The second mean pore size is less than the first mean pore size. The third mean pore size is less than or equal to the second mean pore size. The first, second, and third stage filter are structured to filter an airflow prior to being received by the fuel cell system.

The present disclosure provides a water filter device generated using animal bone. In some embodiments, the water filter device comprises a tube containing a series of layers of animal bone granules.

A system includes a non-transitory computer-readable medium having instructions stored thereon. The instructions, when executed by one or more processors, cause the one or more processors to acquire air quality data regarding an air quality of air upcoming, proximate, or entering an air inlet of a filtration assembly, close or restrict the air inlet in response to the air quality data indicating that the air upcoming, proximate, or entering the air inlet is of a quality lower than a quality threshold to substantially prevent dirty ambient air from entering the filtration assembly, and activate air storage to provide an air supply to the filtration assembly when the air inlet is closed or restricted.
