Publication number: 20080035578Abstract: Disclosed is a three-tank water treatment system. In operation, water flows through each tank in succession, with each tank performing one or more treatment operations. By allocating a separate tank for the copper/zinc redox alloy filtration medium, some embodiments of this system allow for a greater amount of the redox alloy to be deployed than is practical with existing systems. This increases the effectiveness of this type of filtering and increases the lifetime between necessary changes of the filtration media. In a preferred embodiment, the three tanks are placed in a vertical column. Each of the uppermost two tanks has one dome hole or bulkhead hole near its top and another near its bottom. When the time comes to exchange the filtration medium in a tank, the top and bottom holes are opened, and the media is easily drained out and replaced.Type: ApplicationFiled: October 10, 2006Publication date: February 14, 2008Applicant: Bio-Water Technology, Inc.Inventor: Lawrence Robert Powers

Patent number: 7309436Abstract: Methods and systems for removing perchiorate from water are disclosed which involve the use of a plurality of vessels containing an ion exchange resin having affinity for perchiorate ions, and in which perchiorate-contaminated water is passed over the resin in some but not all of the plurality of vessels operating in parallel to one another thereby removing perchlorate ion from the water stream and generating reduced perchlorate content product water streams and in which a subset of the plurality of vessels is removed from service, their resin is removed and replaced and they are returned to service.Type: GrantFiled: September 1, 2005Date of Patent: December 18, 2007Assignee: Basin Water, Inc.Inventors: Peter L. Jensen, Bryan Zinn, John Zitlau

Patent number: 7294265Abstract: An ion adsorption module comprises a container with at least an opening into which feed water flows, and an organic porous ion exchange material having a three-dimensional reticular structure filled into the container, which has a continuous pore structure comprising macropores and mesopores, the macropores being interconnected with each other forming mesopores with an average diameter of 1-1,000 ?m in the interconnected parts, has a total pore volume of 1-50 ml/g, contains uniformly distributed ion exchange groups, and has an ion exchange capacity of 0.5 mg equivalent/g or more of the porous material on a dry basis. The ion adsorption module can be extremely easily filled with the ion exchange material, and the packed layer does not move even if the layer is placed in an upward flow. The ion adsorption module and the water processing method using the ion exchange material are extremely useful.Type: GrantFiled: April 14, 2003Date of Patent: November 13, 2007Assignee: Organo CorporationInventors: Akiko Yoshida, Koji Yamanaka, Hiroshi Inoue

Patent number: 7294266Abstract: The filter cartridge for the water tank of a coffee machine comprises a housing having on both sides a plurality of slot-shaped openings constituting two inlets. For softening the water, the housing of the filter cartridge contains a ion exchange resin. The bottom of the housing comprises a central outlet. The interior of the housing is provided with a plurality of baffle members increasing the length of the flow path of the water between inlets and outlet. The housing comprises an upper portion and a lower portion, sealingly fixed to each other. The baffle members extend essentially in vertical direction and are alternately fixed to the upper and to the lower housing portion. Water passages are provided between the upper housing portion and the baffle members fixed to the lower housing portion, as well as between the lower housing portion and the baffle members fixed to the upper housing portion.Type: GrantFiled: July 8, 2004Date of Patent: November 13, 2007Assignee: SAECO IPR LimitedInventor: Heinz Vetterli

Composite filter and method and apparatus for producing high purity water using the composite filter
Patent number: 7291266Abstract: To compose a composite filter for obtaining water having a high purity usable as water for life and water for medicine from water in which impurities are mixed. Furthermore, to compose an apparatus for obtaining water having a high purity using the filter. Moreover, to configure the apparatus so as to facilitate exchange of the filter. That is, water having a high purity can be obtained by allowing raw water to permeate through a composite filter which consists of a first layer 11 made of fibers, a second layer 12 made of ion exchange resin, a third layer 14 made of activated carbon and a fourth layer 16 made of an unwoven textile. These first layer, second layer, third layer and fourth layer are configured as separate independent filters respectively so that each filter can be exchanged independently. Furthermore, different kinds of filters can be combined dependently on purposes of use.Type: GrantFiled: December 18, 2002Date of Patent: November 6, 2007Assignee: Iida Kensetu Co., Ltd.Inventors: Seisuke Takashima, Ryousuke Murayama, Masatoshi Iida, Masayoshi Furuhashi -

Patent number: 7270745Abstract: Presented is a liquid filtering apparatus and method that overcomes the disadvantages encountered with prior bed filtration systems by providing a filtering apparatus that incorporates a super-buoyant filter medium having a specific gravity very substantially lower than that of the process liquid being filtered. This feature enables a majority of the medium to float on top of the process liquid. Due to the significant differences in specific gravity between the media and the process liquid, super-buoyant media produce a highly advantageous means of naturally, gravimetrically separating both clean and contaminated filter media and process liquid into separate “phases”. Under normal filtering operation, the filter media is contained within a filter housing by a bed support near the top of the filter housing, and particulate material is filtered from a process liquid that passes through the housing.Type: GrantFiled: August 4, 2003Date of Patent: September 18, 2007Inventor: Steven H.

Patent number: 7261811Abstract: Biological nutrient removal (BNR) in municipal wastewater treatment to remove carbonaceous substrates, nutrients and phosphorus, has recently become increasingly popular worldwide due to increasingly stringent regulations. Biological fluidized bed (BFB) technology, which could be potentially used for BNR processes, can provide some advantages such as high efficiency and compact structure. This present invention incorporates the fixed-film biological fluidized bed technology with the biological nutrient removal in a liquid-solid circulating fluidized bed, which has achieved the simultaneous elimination of organic carbon, nitrogen and phosphorus, in a very efficient manner and with very compact space requirements.Type: GrantFiled: February 24, 2004Date of Patent: August 28, 2007Assignee: The University of Western OntarioInventors: George Nakhla, Jingxu Zhu, Yubo Cui
