A method of filtering water contained in a squeezable bottle includes filling the squeezable water bottle with water; screwing a portable filtration apparatus onto the squeezable water bottle, the portable filtration apparatus includes a cap piece, the cap piece having a mouthpiece and a threaded portion, wherein the threaded portion is configured to screw onto the squeezable bottle; and a filter fluidly connected to the cap piece, wherein the filter comprises a plurality of hydrophilic hollow fibers and hydrophobic hollow fibers, the hydrophobic fibers are configured to allow air to flow into the squeezable bottle; flowing a filtrate out through the mouthpiece from the filter in response to a pressure differential between an inside portion of the squeezable bottle and an outside portion of the squeezable bottle.

A separator device for removing particles from suspension in a fluid includes a housing having first and second apertures for ingress and egress of fluid into and out of the housing. A first separator chamber is disposed at one end of the housing. A second separator chamber is disposed at the other end of the housing. A central chamber is disposed between the first and second separator chambers. The first and second separator chambers are apertured for ingress and egress of fluid from the central chamber, and each contains obstruction means to slow the flow of fluid within the chamber.

Filter and method for filtering solve problem of filtering of microfibers. The filter is specifically designed for efficient removal of microfibers from fluids including wastewater such as is emitted by washing machines and clothes dryers in their normal mode of operation. The filter and filtering method hereby disclosed is characterized by the possibility to insert the filtering device directly into existing washing machines without the need for modifications. The filer has a form that allows its direct insertion into an existing void in the washing machine that is connected or an integral part of the drain pump.

A pod assembly for use in a beverage machine is provided. The pod assembly includes a container and a filter disc that is detachably coupled to the container. The container includes a base, a side wall having a lower rim coupling the side wall to an outer perimeter of the base, and a flange coupled to an upper rim of the side wall and extending radially outward from the upper rim. The filter disc includes a central portion with multiple central openings, a dome-shaped portion with multiple secondary openings, an annular portion extending radially outward from the dome-shaped portion, a foot portion extending vertically from the annular portion in a first direction, and a retention flange extending vertically from the annular portion in a second direction.

A construction sink is capable of being connected to an existing water supply, such as an outdoor hose or faucet, such that contaminated water can be discharged outside through a residential or commercial drain line. The construction sink is easily portable and includes a sink for cleaning the various contaminants off of tools or other materials used on a construction site. The construction sink includes a self-contained filtration system that use a series of baffles to filter fluid that has been contaminated during the process of cleaning tools or other materials used on a construction site. As the self-contained filtration system filters the fluid that is contaminated during the cleaning of the tools and materials used on a construction site, it can be connected to pre-existing water and drainage lines found in typical residential or commercial buildings without damaging the lines or causing harm to the environment.

A separator device for removing particles from suspension in a fluid includes first and second fluid-carrying portions and a non-fluid-carrying spacer for linking the first and second fluid-carrying portions. Each of the fluid-carrying portions includes a socket for receiving an open end of a pipe and a connector for connection of the filter. The socket of the first fluid-carrying portion has a pipe receiving depth greater than that of the socket of the second fluid-carrying portion. The sockets of the first and second fluid-carrying portions are positioned on a common axis and facing away from each other when the fluid-carrying portions are linked by the spacer.

A water purifying filter cartridge structure includes: a filter cartridge main body and a filter cartridge bottom seat. The filter cartridge main body includes: a filter barrel, a filter barrel cover, a filter body, a filter chamber, and a back flow check component. The filter barrel cover is disposed on a top portion of the filter barrel. The filter body is adapted to remove impurities from water. The filter chamber is disposed in the filter barrel, and the back flow check component is disposed in the filter barrel. The back flow check component includes a first back flow check piece, a second back flow check piece, and a third back flow check piece. The first back flow check piece and the second back flow check piece are adapted to prevent back flow at the water input end.

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 grease trap for separating waste from waste water that includes grey water and FOG includes a tank having a bottom and an interior volume. An inlet invert in the tank has a discharge end for discharging waste water into the tank, and an outlet invert in the tank has a drain end for removing grey water from the tank. A first baffle across the interior volume below the discharge of the inlet invert and above the drain end of the outlet invert has a hole allowing grey water to descend through the hole to a path under the first baffle to the drain end of the outlet invert. A second baffle across the interior volume above the discharge of the inlet invert has a hole allowing FOG to float through the hole in the second baffle to collect above the second baffle.

A magnetic filter (10) includes first and second separation chambers (10, 12). The separation chambers (10, 12) each have an inlet and an outlet, and the separation chambers (10, 12) are joined together such that the inlets of the first and second chambers are adjacent, and the outlets of the first and second chambers are adjacent. An inlet port arrangement (28) connects both inlets to a single inlet pipe, and an outlet port arrangement (30) connects both outlets to a single outlet pipe.
