Abstract:
In a method for desalting aqueous solutions by means of electrodialysis in an electrochemical cell (10) comprising a first electrode (16) and a second electrode (20), wherein the second electrode (20) has a polarity opposite to the first electrode and wherein at the first electrode (16) an electrolysis gas and ions are formed, it is proposed that the electrolysis gas and the ions are reacted at the second electrode (20).
Abstract:
A process and a system for enhancing recovery of oil from an oil-bearing formation are provided in which water having a total dissolved solids content is filtered to remove some solids in a filter assembly, the filtered water is treated to remove some ions in a capacitive deionization assembly, and the filtered deionized water is injected into the oil-bearing formation to mobilize crude oil and enhance oil recovery from the formation.
Abstract:
An electrochlorination and electrochemical system for the on-site generation and treatment of municipal water supplies and other reservoirs of water, by using a custom mixed oxidant and mixed reductant generating system for the enhanced destruction of water borne contaminants by creating custom oxidation-reduction-reactant chemistries with real time monitoring. A range of chemical precursors are provided that when acted upon in an electrochemical cell either create an enhanced oxidation, or reduction environment for the destruction or control of contaminants. Chemical agents that can be used to control standard water quality parameters such as total hardness, total alkalinity, pH, total dissolved solids, and the like are introduced via the chemical precursor injection subsystem infrequently or in real time based on sensor inputs and controller set points.
Abstract:
The invention relates to an electrochemical cell, particularly useful in electrochemical processes carried out with periodic reversal of polarity. The cell is equipped with concentric pairs of electrodes arranged in such a way that, in each stage of the process, the cathodic area is equal to the anodic area.
Abstract:
A mobile water treatment facility may include, in one example operation, receiving used, dirty and/or waste water from a well or other source. The water may then be prepared for a treatment cycle by modifying the water and applying a voltage to the water inside an electrode array in order to remove the sediment from the water to provide recycled water for continued use. The process may be performed by a full capacity device or via a mobile treatment and testing unit that operates by cycling the water at a smaller volume and rate for analysis and testing purposes prior to engaging a full flow-rate treatment device.
Abstract:
This invention provides a one-stage process for generating a biocidal solution in situ, including a reaction between an ammonium salt and an electrolytically generated bromine oxidative species.
Abstract:
An electrolyzed water processor chamber with an anodic chamber having an anode plate held in an anode tray, and a cathodic chamber having a cathode plate held within a cathode tray. The plates are charged by an electrical current, to separate an incoming water stream into its electromagnetically ionized alkaline and acidic components, across an ion exchange membrane sandwiched between the anode and cathode plate trays. The trays can include sets of ducts and cavities, so that when the trays are stacked together, with the cavities aligning to form plenums for the routing of water between the trays. The trays stack as modular units, so that any multiple of the anodic and cathodic tray pairs, with their plates and sandwiched membrane, can be stacked together and function as a combined processor chamber, with end caps mounted on the top-most and bottom-most plate trays.
Abstract:
A deionization apparatus for regenerating electrodes using vibration and a method of controlling the same. The deionization apparatus includes electrodes to which ions contained in a fluid are absorbed, and a piezoelectric element to separate the ions absorbed to the electrodes by vibration. Since the ions absorbed to the electrodes are separated using mechanical energy generated by the piezoelectric element, it may be possible to more rapidly perform regeneration of the electrodes.
Abstract:
An oxidizer generating apparatus comprising a cylindrical housing and an electrode assembly attached at one end of the housing comprising at least three vertically disposed electrodes, the electrodes being spaced apart so as to define a water flow path between them, the electrodes comprising titanium outer electrodes and at least one inner diamond electrode.
Abstract:
A system for producing high purity water, and particularly for the production of water that is suitable for injection, as well as method of using the same, are disclosed. The system includes a unique combination of known water purification methods that is particularly well-suited to the production USP purified water and USP water that is suitable for injection. The system minimizes potential for organism growth within the system by providing multiple means of organism destruction and removal and by not utilizing any standard water treatment media.
