| 20080237060 | METHODS AND APPARATUS FOR ELECTROLYTIC TREATMENT OF WATER - Apparatus and related methods for increasing dissolved oxygen levels in water to remove iron and/or manganese. A dissolved oxygen treatment system includes a control system having a power supply and an electrode placed within a water chamber. At the electrode, water is converted into hydrogen gas and oxygen gas, wherein the oxygen gas remains in solution and increases the concentration of dissolved oxygen gas in the water. The dissolved oxygen treatment system can be manually configurable wherein the electrode is selectively wired to use either portions of or the whole electrode based upon testing of the water source with a dynamic electrode test system. Alternatively, the dissolved oxygen treatment system can include a smart controller, a variable power supply and a fixed size electrode, wherein the smart controller continually controls the power output to the fixed size electrode so as to control the amount of dissolved oxygen that is generated. | 10-02-2008 |
| 20080237924 | FILTER CARTRIDGE AND METHOD OF CONSTRUCTION THEREOF - A filter cartridge includes a one-piece housing having a port and a filtration element disposed in the housing. The filtration element is a coherent filter block that can be, but is not necessarily, larger in cross dimension than the port. In one embodiment, the filtration element is a coherent filter block that generally conforms to the shape of the hollow interior, but is slightly smaller than the hollow interior so as to define a gap between the filtration element and the inner surface. One method for constructing a filter cartridge includes providing a housing having a hollow interior and at least one port, introducing a granular material into the hollow interior via the port, and transforming the granular material in the hollow material into a coherent filter block. Another method for constructing a filter cartridge includes providing a filtration element in the form of a coherent filter block, and overmolding a housing around the filtration element. | 10-02-2008 |
| 20090090415 | CHEMICAL DELIVERY SYSTEM - An expandable chemical delivery system sharing a common bulk fluid inlet and bulk fluid flow path to direct a bulk fluid through one or more selected chemical eductors. Each chemical eductor is slidably insertable into an eductor port on the manifold body such that rotation of the chemical eductor is not required for installation. After installation, the orientation of the chemical eductor can be rotatably adjusted so as to avoid interference with adjacent chemical eductors. Delivery of a bulk fluid to each chemical eductor is controlled via a corresponding valve assembly that selectively allows or blocks flow of the bulk fluid form the bulk fluid flow path to the corresponding chemical eductor. The manifold body can include a plurality of individual manifold bodies approximated with a coupling system to define the bulk fluid flow path. Alternatively, the manifold body can comprise a single fabricated body for high pressure operation. | 04-09-2009 |
