    Abstract: A container (10) for water comprising: a container housing (11) for holding water, the housing having a base, side walls and a top wall; a water filter (19) comprising one or more membranes (22) which are effective to pass water in preference to air under the influence of a pressure differential; an output valve (20) coupled to the water filter (19); and, a pump (18) for establishing a pressure differential across the walls of the container housing, wherein the container housing comprises a main volume (MV) within which the water filter (19) extends and a header volume (HV) above the water filter. For a given internal capacity of a water container of the present invention, the provision of a header volume ensures that the surface area of the water filter in contact with water in the main volume is constant so long as there is water within the header volume. This keeps the membranes of the water filter working at maximum efficiency for longer than they would otherwise.

    Abstract: A method for transferring heat includes flowing a wastewater through a tank and flowing a fluid through a heat exchanger having an outer surface. The method further includes aerating the wastewater to produce a convective flow, contacting the outer surface of the heat exchanger with the convective flow to exchange heat, and cleaning the outer surface of the heat exchanger with the convective flow. A system for transferring heat includes a tank, a heat exchanger with an outer surface disposed in the tank, and a fluid flowing through the heat exchanger. Wastewater located in the tank flows over the outer surface of the heat exchanger, and a diffusion pipe disposed in the tank provides air into the tank to produce a convective flow in the wastewater.

  • Patent number: 8573407
    Abstract: A lubricant reclamation system having a moisture absorbent cartridge (140). The cartridge (140) is fabricated placing a Superabsorbant Polymer (SAP) (142) within a boundary of polyester mesh (143). Moisture is extracted from a lubricant or other fluid and absorbed by the SAP. The moisture latent SAP bonds to the polyester mesh (143), potentially turning into a gel. A layer of polypropylene sorbent (144) is placed about the exterior of the boundary material (143), ensuring any moisture remains exterior to the sorbent layer (144). A resin layer can optionally be placed within a fluid flow following the discharge from polypropylene sorbent extracting aerosol from within the lubricant and as a barrier of detrimental ions with an exchange of beneficial ions. The entire cartridge can be placed within an enclosure or pouch body (162). The body (162) is designed to expand, accommodating a resultant increase in SAP volume. The cartridges can be integrated into filters comprising commonly known filtration elements.

  • Patent number: 8043504
    Abstract: A filter cartridge that is designed to accommodate differences in lengths between an outer filter media and an inner filter media by providing a flexible connection between the inner filter media and the outer filter media. In addition, the endplates of the inner filter and the outer filter together define a gasket groove that receives a gasket. Using the endplates of the inner and outer filter media to define the gasket groove eliminates a mold parting line that can lead to fluid leakage.

  • Patent number: 7998349
    Abstract: The present invention relates to a device having two or more separate filtration layers that can be independently tested for integrity yet which allow for serial filtration through the two or more layers to obtain the desired characteristics such as retention. The device is made of two or more filtration areas, each containing one filter layer. Each area has one filtration layer and a first endcap bonded to a first end of the filter and a second endcap bonded to a second end of the filter. The areas are arranged concentrically around each other such that the first area is inward of the second area which is inward of a third area and the like. Each area is formed separately and integrity tested separately before final assembly. The first area is slid into the inside of the second area and then the two endcaps are either bonded to each, bonded to a third overall endcap or overmolded by a third endcap.

  • Patent number: 7992723
    Abstract: A filter includes filter media and a housing surrounding the media. The housing has an outlet and is sealed such that all fluid flow out of the outlet must first enter the cartridge and pass through the media. The housing has multiple inlet flow paths configured so that fluid impinging on the housing is diffused as it enters the cartridge and is prevented from flowing directly towards the filter media.

  • Patent number: 7981293
    Abstract: Methods and apparatuses for treatment of contaminated liquid are provided including an integrated ultra-filtration and clarification apparatus, and an optional integrated electrocoagulation capability. The integrated apparatus comprises an outer tank, an inner casing, and a plurality of ultra-filtration filters contained within the inner casing. Clarification of liquid occurs in the gap between the casing and tank. Solid matter settles, and aggregates in the bottom portion of the tank. The accumulated solid material acts as a secondary filter by pre-filtering the liquid prior to contact with the ultra-filtration filters. Clarified liquid is retained in a chamber of the casing, and the clarified liquid is drawn through the ultra-filtration filters as initiated by a source of vacuum communicating with the ultra-filtration filters.

  • Patent number: 7935255
    Abstract: A filter cartridge configured as a filter-in-filter design with an inner filter and an outer filter. The filter cartridge has features, for example an overhanging lip, to engage with a lid of a filter housing in which the cartridge is installed such that the lid is connected to the cartridge. As a result, the cartridge can be connected to the lid to facilitate installation and removal of the cartridge. Alternatively, the same features that allow connection with the lid permit a user to manually grasp the cartridge during installation and removal so that the cartridge can be used without a lid having attachment features. The filter cartridge is also designed to enable use of a longer inner filter within the outer filter. A longer inner filter increases the amount of filter media available for filtering the fluid.
