Abstract:
An electrolytic device and method for generating a disinfecting solution that utilizes a brine generator, an electrical circuit with an on-board solar panel and rechargeable storage battery. The electrical circuit preferably conditions the power received from a variety of power sources to charge the storage battery and conditions the power stored in the storage battery to provide the appropriate power to maximize the disinfection efficacy of the disinfecting solution. The on-board solar panel and/or rechargeable battery can be utilized as the power source to recharge or operate other devices such as cell phones, PDAs, flashlights, GPS systems, or other such devices. The device can incorporate a touch screen display and electronics that is an electronic “water finder” application for locating sources of water that can be made potable. The device can incorporate a biocidal agent and foul resistant water filter that can be folded up to provide a compact configuration for storage.
Abstract:
An automated self-propelled robotic pool cleaner having a housing and drive means for moving the pool cleaner over at least the bottom wall of a pool, is provided with an integral on-board electrochemical chlorine generator for producing chlorine from a chlorine compound, e.g., sodium chloride, that is dissolved in the pool water, a source of electrical power operatively connected to the electrochemical chlorine generator, control means for initiating and terminating the operation of the chlorine generator, and an outlet for discharging water containing chlorine ions produced by the electrochemical generator to thereby distribute the chlorine into the water proximate the exterior of the pool cleaner housing as the pool cleaner follows a programmed operational mode across the bottom and/or side walls of the pool. The operation of the chlorine generator is in response to a manually operated switch and/or signals generated by an automated testing probe, which signals are transmitted directly or indirectly to the control means.
Abstract:
Systems and methods utilizing a capacitive charging power source for fluid treatment reactors are disclosed. In an example embodiment, a DC power source charges a capacitor circuit configured to store energy. A switching circuit with an input connected to the capacitor circuit has reversing polarity outputs which provide a pulsed discharge of energy at a frequency with an adjustable duty cycle. An inductive load may be connected to the reversing polarity outputs, and a fluid treatment reactor with at least two electrodes may be connected to the inductive load.
Abstract:
An apparatus and method for removing contaminant species from water by electrocoagulation are described. Alternating grounded, rotating, planar circular electrodes and stationary planar electrodes function as a Tesla fluid pump when placed in contact with the contaminated water, causing the water to flow between the rotating and stationary electrodes. An insoluble abrasive material introduced into the water removes scale from the electrodes while the water is pumped thereby. A direct electric current is caused to flow between each pair of rotating and stationary electrodes, thereby producing electrocoagulation of the contaminants in the water flowing therebetween. The electrocoagulated materials may be separated from the treated water by filtration or by permitting the treated water to stand for a chosen period.
Abstract:
An Electrolytic cell to produce Electrolysis with the use of graphite, a non metallic electrolysis element in the cell, into water passing through the cell without the use of metallic electrolysis elements. Water passing through the cell is thereby affected by the electrolysis with the use of non metal components in contact with the water to generate the electrolytic reaction. The cell being oriented with the inlets and outlets in a downward direction so that if the water remains in the cell, gaseous vapor produced by the electrolysis will eventually fill the cell cavity and stop electrolysis thereby limiting the accumulation of excess amounts of hydrogen gas from the electrolysis in the cell.
Abstract:
A method for converting waste water into potable water using power from an electrical grid. The method comprises flowing the waste water through an electrolysis cell coupled to the grid, and, when power availability on the grid is above an upper threshold, biasing the electrolysis cell to form hydrogen. Hydrogen evolved in the electrolysis is then provided as fuel to one or more fuel cells. When the power availability on the grid is below a lower threshold, electric current and potable water are drawn from the one or more fuel cells.
Abstract:
A method and apparatus for desalinating saltwater using concentration difference energy is disclosed. In order to desalinate saltwater that is contained within a product chamber, a drive cell is used to generate a drive voltage. The product chamber has a desalination voltage such that when a sufficient voltage is applied to the product chamber, anions and cations migrate out of the product chamber, thereby desalinating the water. The sufficient voltage, which includes the drive voltage and which is equal to or greater than the desalination voltage, is applied to the product chamber, consequently effecting desalination. Beneficially, concentration difference energy can be generated using a concentrated solution, which can be generated using, for example, solar energy.
Abstract:
The present invention is concerned with a miniature ozone generator device for purifying water. The device includes a printed circuit board having an ozone producing circuit printed on it which includes anodes and cathodes alternatively printed and connected in parallel relationship to each other and to a power supply device. The electrodes have rough (non-smooth) surfaces. In use, when the ozone generator is plunged into a vessel containing the water to purify, this leads to a coalescence of hydrogen bubbles produced by the cathodes into larger hydrogen bubbles, and thus to a higher production of ozone by the anodes.

A capacitive deionization (CDI) system for deionizing water is disclosed. The CDI system comprises at least a flow through capacitor (FTC) module, at least a first supercapacitor, at least a second supercapacitor, at least a third supercapacitor and a controller. The FTC module comprises a plurality electrodes for removing ions from water flowing between the electrodes under an electric field applied between the electrodes. The first supercapacitor is connected between the potential source and the FTC module for amplifying energy provided by the potential source. The second supercapacitor is connected to the FTC module for receiving energy from the FTC module for regenerating the electrodes of the FTC module. The third supercapacitor is adapted for exchanging energy with the FTC module for regenerating the electrodes of the FTC module. The controller is adapted for regulating deionization rate of the water and regeneration of the electrodes of the FTC module.
