| 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 |
| 20090008267 | PROCESS AND METHOD FOR THE REMOVAL OF ARSENIC FROM WATER - This invention describes a one step process for the removal of heavy metals, particularly arsenic, from water. The process consists in promoting the circulation of the water to be treated in an electrolytic cell equipped with iron, or iron alloy anodes and cathodes made of iron or iron alloy or other metals, while the contemporary insufflation into the cell of a gas, partially or totally composed of oxygen. In this way the iron of the anode electrodes dissolves as iron hydroxide. The ferrous hydroxide thus generated, under the action of the oxygen contained in the insufflated gas is converted to ferric hydroxide, which, through a complex mechanism, adsorbs and forms insoluble complexes with the arsenic ions. At the same time As(III) is subject to oxidation both at the anode and at the cathode. By this process both forms of arsenic, As(III) and As(V), are equally removed. The treated water is further processed by conventional clarifying and filtering. | 01-08-2009 |
