  • Patent number: 8524080
    Abstract: An apparatus for removing cyanotoxins and excess ions from contaminated water. Contaminated water passes from a storage tank (200), through a sand filter (210), through a reaction chamber (230), and finally through a carbon filter (270). The sand filter removes particulates and some bacteria. Treatment of the water in the reaction chamber first destroys cyanotoxins, algae, and bacteria through the use of high voltage shocks applied between two groups of electrodes (285, 285?), then the voltage on the electrodes is lowered and electrolysis is used to sequester free ions in the water in the region near the electrodes. Partially treated water is removed from the upper portion of the reaction chamber and passed through a carbon filter (270) to remove radiation, and to improve taste and smell. After passage through the carbon filter, the water is potable. The water remaining in the reaction chamber is discarded into a reservoir (265).

  • Patent number: 8460532
    Abstract: The present invention provides a new method and apparatus/system for purifying ionic solutions, such as, for example, desalinating water, using engineered charged surfaces to sorb ions from such solutions. Surface charge is applied externally, and is synchronized with oscillatory fluid movements between substantially parallel charged plates. Ions are held in place during fluid movement in one direction (because they are held in the electrical double layer), and released for transport during fluid movement in the opposite direction by removing the applied electric field. In this way the ions, such as salt, are “ratcheted” across the charged surface from the feed side to the concentrate side. The process itself is very simple and involves only pumps, charged surfaces, and manifolds for fluid collection.

  • Patent number: 8377280
    Abstract: The present device is a microchannel separator that uses a separation driving force created by an electric field. An ionic fluid flows through the microchannels and is subjected to an electric field by two spaced apart parallel electrodes possessing an electric charge. The ions in the ionic fluid are attracted towards the charged electrodes and thus are concentrated in the region of flow near the charged electrodes and depleted from the central region of flow between the charged electrodes. The charged electrodes are insulated from the ionic fluid by an impermeable barrier which prevents arcing and adherence of the ions to the charged electrodes. After a sufficient length of passage of the ionic fluid through a main channel two blocking plates separate the flow into a central and two outer output channels. The central channel draws a portion of the ionic fluid from the central region of the main channel that has fewer ions than the ionic fluid in the regions near the charged electrodes.

  • Patent number: 8357280
    Abstract: The invention is a method of phase separation in liquid mixtures comprising two or more components. The method comprises the steps of inserting the liquid mixture between suitably shaped and positioned electrodes and applying a voltage to the electrodes in order to produce a non-uniform electric field between the electrodes. The phase separation takes place with essentially all electrode geometries and the phase separation is reversible. The method is characterized in that the liquid mixture must contain dissociated positive or negative ions. In this case the phase separation takes place when the applied voltage is a few volts or less and when the temperature is many degrees above the binodal (coexistence) temperature Tc. The invention has many practical applications including: electrical field controlled lubrication, influencing the kinetics and spatial dependence of chemical reactions in liquid environments, controlling the propagation of light, and controlling the opacity of a window.

The electric current of the first treatment vector and the voltage and frequency of the magnetic pulse of the second treatment vector may be reduced as the treatment process proceeds. During treatment, total dissolved solids (TDS) rise and congeal at the top of the water. The congealed TDS are removed from the water. An additional filtering process may be applied.
