Abstract: The present invention discloses a rectangular shaped filter and coalescer elements and a vessel that houses a plurality of such rectangular shaped elements. Greater filtration or separation efficiency is provided due to increased number and alignment of rectangular shaped filter elements in the vessel. The rectangular shaped filter elements are also easy to replace.

Abstract: The invention features a filtration segment having a top seal, a bottom seal and a primary filter core and the method of filtering with the design of the filtration segment. The primary filter core is operatively coupled to at least one opening which is located either on the top seal or on the bottom seal. The filtration segment also includes one or more interior filters surrounding the primary filter core. Each interior filter includes a filter material surrounding a secondary core which is operatively coupled to at least one opening which is located either on the top seal or on the bottom seal. Each filter may optionally include a retaining medium enclosing the filter material. The filtration segment has one or more layers of an exterior filter media which operatively surround the interior filters and are operatively coupled to the top seal and the bottom seal.

Abstract: The present invention discloses a method for self-cleaning filters without having to open the filter housing. Wash nozzles are integrated with the filter housings such that when the filters are clogged, both back-wash and regular washing can be performed with practically no down time. Moreover, without opening the filter housing, the hazardous components of the fluid to be filtered can be contained and dealt with before they escape the filter housing, thereby significantly reduces the environmental impact and harm to the working crew.

Abstract: Method and apparatus are provided for treating and removing particulate matter from fluid or treating and removing fluid from a recoverable particulate matter from fluid circulating into, through and out of an industrial operation, and for washing a disposable cartridge filter used therein. The influent fluid is maintained at a flow rate such that the differential pressure across the cartridge filter is no greater than 10 psi to prevent the buildup of non-porous filter cake. A pressure detecting mechanism and method is also provided to detect the amount of deposited particulate matter inside the cartridge filter, so that an operator can determine whether the cartridge filter should be taken out to remove or recycle the deposited particulate matter.

Abstract: A filter element and method has at least two fluid barriers disposed in the filter media, which do not extend the length of the filter. The barriers direct the fluid to be filtered through a path in the filter element, and the fluid makes at least two passes in the media.

Abstract: A method of filtering fluids with different specific gravities as well as particles or other impurities.

Abstract: A filter including a first flow path having a plurality of interconnected channels and a second flow path having a plurality of interconnected channels. The channels of the first and second flow paths are alternatingly configured in a substantially concentric pattern. A filter media is interposed between the channels of the first and second flow paths. A filter including a filter media arranged in a plurality of substantially concentric layers; a fluid outflow system contacting the entirety of one side of the filter media, and a fluid inflow system contacting the entirety of an opposite side of the filter media.

Abstract: Method and apparatus are provided for treating and removing particulate matter from fluid circulatable into, through and out of an industrial operation, and for cleaning a disposable cartridge filter used therein. In treatment of fluid, the fluid is circulated in a flow path and is introduced into a filter vessel having a disposable cartridge filter. The fluid flows through the cartridge filter at a rate of flow insufficient to produce a buildup of a substantially non-porous solids filter cake around the exterior of the cartridge filter. The clean fluid is circulated to the industrial operation. The cleaning method and apparatus includes a storage vessel in selective fluid communication with the interior of the first vessel such that clean fluid may be flowed from the storage vessel into the interior of the cartridge filter then through and thereafter exterior of the cartridge filter to effectively remove the particulate matter deposited on or around the exterior of the cartridge filter.
