摘要： A system is provided for removing dissolved metals from industrial wastewater by electrocoagulation. The system includes an electrocoagulation reactor with a DC power supply having an insulation support enclosure with positive and negative electrode plates disposed thereon. The electrode plates are insulated for each other but remain in direct contact with the wastewater as it flows between the electrodes. The DC power supply induces opposite charges on alternate electrodes thereby generating an electric field between adjacent electrodes to cause the electrodes to ionize and go into solution for interaction with the contaminants in the wastewater as it flows through the reactor. The reactor is housed in a pressure vessel container so the exterior pressure on the reactor is higher than its internal pressure preventing leakage of fluids and oxygen and hydrogen gases produced in the reactor by decomposition of water. The pressure vessel allows higher operating pressures to retain higher concentrations of dissolved oxygen and hydrogen dispersed in the water for reaction with the contaminants. The electrical supply includes explosion proof connection housings for operation in hazardous environments. The system also includes a cyclone filter for separating the precipitated solid particles from the fluid and automatic control of the reactor by monitoring fluid flow, temperature, pH, and pressure.

摘要： An electrolytic process and apparatus purifies contaminated bulk aqueous solutions and remediates soil. The apparatus is an electrolytic treatment or remediation unit consisting of one or more electrolytic cells having a cathode chamber separated from at least one anode chamber by a separation membrane. The cathode chamber has cathode plates positioned at an angle to the perpendicular or vertical axis of the cell made of valve metals with an irreducible oxide coating. Non-turbulent flow of the solution in an interfacial zone adjacent to the cathode is controlled by the evolution of hydrogen during electrolysis, resulting in a steady state flow of colloidal particles and cations in the cathode-solution interface sufficient to collapse the Gouy-Chapman layer, thereby causing total and irreversible agglomeration of all colloidal particles. A separation membrane separates cathode and anode chambers and allows conductivity driven ionic transfers, and prevents electro-osmotic reflux of the anolyte. A maximum pH difference between the cathode and anode chambers, yielding a cathode chamber maximum pH of 9.8 and an anode chamber minimum pH of 3.2, ensures that the transient pH in the interfacial zone rises to levels in excess of 12.0, thereby enabling the precipitation of phosphates as alkaline earth phosphates and the hydrolysis of urea resulting in the oxidation of ammonia to form an oxidant for dissolved organic materials. The contaminated aqueous solution is subjected to high current density electrolysis, after which it is passed to a holding chamber, a filter chamber, and thereafter to at least one anode chamber.

摘要： Deionizers using the electrode configurations of electrochemical capacitors are described, wherein the deionizing process is called capacitive deionization (CDI). During deionization, a DC electric field is applied to the cells and ions are adsorbed on the electrodes with a potential being developed across the electrodes. As electrosorption reaches a maximum or the cell voltage is built up to the applied voltage, the CDI electrodes are regenerated quickly and quantitatively by energy discharge to storage devices such as supercapacitors. In conjunction with a carousel or Ferris wheel design, the CDI electrodes can simultaneously and continuously undergo deionization and regeneration. By the responsive regeneration, the CDI electrodes can perform direct purification on solutions with salt content higher than seawater. More importantly, electrodes are restored, energy is recovered and contaminants are retained at regeneration, while regeneration requires no chemicals and produces no pollution.

摘要： An electrically regeneratable battery of electrochemical cells for capacitive deionization (including electrochemical purification) and regeneration of electrodes is operated at alternate polarities during consecutive cycles. In other words, after each regeneration step operated at a given polarity in a deionization-regeneration cycle, the polarity of the deionization step in the next cycle is maintained. In one embodiment, two end electrodes are arranged one at each end of the battery, adjacent to end plates. An insulator layer is interposed between each end plate and the adjacent end electrode. Each end electrode includes a single sheet of conductive material having a high specific surface area and sorption capacity, preferably a sheet formed of carbon aerogel composite. The battery further includes a plurality of generally identical double-sided intermediate electrodes that are equidistally separated from each other, between the two end electrodes. As the electrolyte enters the battery of cells, it flows through a continuous open serpentine channel defined by the electrodes, substantially parallel to the surfaces of the electrodes. By polarizing the cells, ions are removed from the electrolyte and are held in the electric double layers formed at the carbon aerogel surfaces of the electrodes. As the electrodes of each cell of the battery are saturated with the removed ions, the battery is regenerated electrically at a reversed polarity from that during the deionization step of the cycle, thus significantly minimizing secondary wastes.

摘要： A portable oxidant generator for generating a chlorine or chlor-oxygen solution suitable for sterilizing contaminated drinking water, thereby providing a water disinfection system and potable water. The oxidant generator includes an electrolytic chamber and a power supply or source. The chamber holds a salt brine solution such that the solution is in contact with an anode and cathode included in the chamber. The power supply provides electrical charge that is passed between the anode and cathode through the salt brine solution. In the preferred embodiment of the present invention, a combination manual pump/switch is activated and injects electrolyte into the cell chamber and electrolyzes the solution. In one embodiment, as electrolysis proceeds, hydrogen gas is liberated and causes a gas pressure within the cell chamber thereby forcing the freshly generated oxidant solution from the cell. In another embodiment, as electrolysis proceeds, hydrogen gas is liberated and causes gas pressure within the sealed cell chamber which acts against a spring loaded piston thereby increasing the chamber volume to minimize pressure buildup, and to maintain the electrolyte in contact with the anode and cathode throughout the electrolysis process irrespective of the orientation of the device. When electrolysis is complete, an electric valve is actuated that allows the freshly produced oxidant to be discharged in to the drinking container to provide disinfection and render the water potable.
