Abstract:
A novel water flow facilitator for granular filter devices that operate under gravity and contain granular particles, further consisting of plastic pellets that are 2 to 100 times, preferably 5 to 20 times larger than the granular particles; the plastic pellets having an aspect ratio of 0.5 to 10, preferably 1 to 4; that comprise about 1 to 50%, preferably 5 to 15% of the weight of the filter media; that have a specific gravity of 0.5 to 2, preferably 0.9 to 1.5. The plastic pellets should contain antimicrobial agents that protect the granular media from microbiological growth. The plastic pellets are made from any of the following plastics: polyolefins, various kinds of polyacrylates, polyvinyl polymers, nylon, polycarbonates etc. The plastic pellets may contain fillers such as calcium carbonate, titania, silica, or alumina. The invented flow facilitator is utilized in a gravity fed granular filter device to remove contaminants such as chlorine, taste and odor-causing compounds, solvents, pesticides, dissolved organic impurities, dissolved heavy metals and non-metallic impurities such as perchlorates. The invented flow facilitator is utilized in a gravity fed granular filter device in which the media consists of activated carbon, synthetic ion exchange resins, silica, alumina, titania, green sands, iron oxides or mixtures thereof.
Abstract:
A filter coalescer cartridge for treating jet fuels is disclosed. The filter coalescer cartridge has spaced apart filter/coalescer layers to effectively remove particulate contaminates and water from the transient fuel being treated. The outer most layer is a knitted sock material formed from cotton threads including a metallic silver disposed thereon to provide an anti-microbial property to the sock material.
Abstract:
There is disclosed a water treatment appliance, particularly for on-the-counter treatment of potable water. The appliance comprises: a base unit comprising a pump, a housing and a cooling unit for chilling water in the housing; a removable water reservoir engageable with the housing; a control panel comprising a water dispensing switch; an outlet for dispensing treated water from the fluid treatment system; and a treatment cartridge removably disposed in the housing. The treatment cartridge comprises a first chamber and a second chamber in communication with one another. The first chamber is in communication with the housing and has disposed therein a filter element. The second chamber is in communication with the outlet and has disposed therein an ultraviolet radiation lamp.
Abstract:
An apparatus, system, and method for removing sediment from water is disclosed. According to one embodiment of the present invention, the apparatus includes a tubular filter assembly comprising a support member; and a filtratable element surrounding the support member, the filtratable element comprising a backing mesh; and a fibrous batting. A system for removing sediment from water is disclosed. According to one embodiment, the system includes a filter chamber to receive a liquid having suspended particles therein; at least one filtration cartridge housed within the filter chamber, wherein the filtration cartridge comprises at least one elongated filtratable element, each filtratable element comprising a support member, and a filtratable media adapted to surround the inner core. A method for removing sediment from water is disclosed. According to one embodiment, the method for removing suspended particles from a liquid includes (1) receiving liquid containing suspended particles into a filter chamber, wherein the filter chamber comprises an inlet and outlet positioned to create pressure differential sufficient to drive the liquid through the filter chamber; (2) filtering the suspending particles from the liquid through at least one elongated filtratable element; and (3) discharging the filtered liquid.
Abstract:
A filter has a longitudinal axis with an inner diameter defined by a hollow longitudinally extending center. The filter has fingers extend radially outwardly arcuately from the longitudinal axis. The fingers have base ends near the longitudinal axis and outer edges at extremities spaced from the longitudinal axis. The outer diameter of the filter is defined by the outer edges of the fingers. The filter is formed from a sintered porous molded thermoplastic or another material resulting in a filter more rigid than standard filters. The fingers are spaced apart from one another a predetermined, substantially fixed distance to form slots therebetween sized to capture contaminants therein.

Abstract:
A filter system for spas and swimming pools is disclosed having a primary filter containing a porous membrane made of multiple plies. A fluid purifying medium in the form of irregularly shaped copper and zinc alloy particles is captured between the plies and placed in contact with the spa water to kill bacteria and remove heavy metals, precipitates and chlorine as the water cycles through the filter. A micro filter for filtering particles surrounds the primary filter, the micro filter and primary filter are mounted in a chamber in fluid communication with the spa or pool. Another particulate filter is positioned upstream of the micro filter and primary filter. A secondary micro filter and primary filter provide filter capacity augmentation through a parallel flow path during periods of increased demand.
Abstract:
A strainer basket is used in conduits or fluid systems and includes a non-metallic strainer basket in which a bio-cide is disposed to combat algae and fungal buildup along the surface of the basket and/or in the openings of the basket.
Abstract:
The invention relates to a system and a method for well completion, control and monitoring of processes in a reservoir. A combined prefabricated liner and matrix system (4) with defined properties for fast and simple well and/or reservoir completion, monitoring and control is provided. An embodiment of the combined prefabricated liner and matrix system 4 includes an outer perforated tubular pipe system 6, an inner tubular screen 7, and a matrix 8. A method for control and monitoring of processes in a well or reservoir using the combined liner and matrix system is also described. The combined liner/matrix system may be used in any process equipment, such as reactors, separators and storage tanks. The system may also be used in a gas/oil/water producing or injection well for well completion, control and monitoring.
