A filtration assembly filters diesel fuel used by a diesel engine and includes a filter element disposed within a housing. The housing includes an unfiltered fuel inlet and a filtered fuel outlet. The filter element disposed within the housing receives fuel from the fuel inlet. The filter element defines a peripheral wall sealably engaging filter media defining an unfiltered side and a filtered side of the filter element. The unfiltered side is enclosed with an impermeable barrier affixed to the peripheral wall and the filtered side is enclosed with a permeable water diffuser through which filtered fuel passes. A water separator assembly is disposed externally to the filter element receiving filtered fuel from the water diffuser. The water separator assembly includes water separator media preventing water from passing into the separator. The separator assembly interconnects to the filtered fuel outlet providing filtered, dewatered diesel fuel to the diesel engine.

A filter assembly for filtering diesel fuel used by a diesel engine includes a housing that defines a housing opening, an unfiltered fuel inlet and a filtered fuel outlet. A panel is matable to the housing for sealably enclosing the opening for forming a housing chamber. A panel encloses the opening and defines an inner surface. A filter element formed from a peripheral wall includes filter media defining an unfiltered side and a filtered side of said filter element. The peripheral wall is sealably affixed to the inner surface enclosing the unfiltered side of the filter element from the housing chamber defining an unfiltered chamber. A permeable barrier is affixed to the peripheral wall defining a filtered chamber with the filtered side of said filter element receiving filtered fuel through the filter media. The housing chamber receives filtered fuel through though the permeable barrier.

A wastewater treatment device for decomposing solid matter using aerobic microorganisms in a bacteria bed, includes a decomposition tank that accommodates the solid matter obtained by crushing food waste and the bacteria bed, a water supply capable of supplying water to the decomposition tank, and a stirrer for stirring the solid matter and the bacteria bed in the decomposition tank. The bacteria bed includes a carrier made of a synthetic resin having a plurality of pores and microorganisms carried in the plurality of the pores.

A filter device is configured to filter a liquid. The filter device includes a drum sized to receive the liquid and a plurality of filter panels coupled to the drum to define a plurality of discs. The liquid passes through at least a portion of one of the discs. Each filter panel includes a perimeter frame that defines a panel normal flow area and a filter media coupled to the perimeter frame. The filter media may be adapted to include a plurality of pleats.

A fluid filter apparatus comprising an upper housing shell; a lower housing shell; a pleat pack element comprising a peripheral frame and a folded pleated media. The frame is at least partially molded over the media to secure the media in the frame, and the media comprises two or more types of media of different densities from each other. A flow control element is disposed for changing the proportion of flow between the first media and the second media responsive to changes in at least one of temperature, pressure, flow rate and/or viscosity of the fluid.
