Abstract:
A device includes a first electrode and a second electrode spaced from the first electrode to define a volume. An anion exchange membrane and a cation exchange membrane are disposed within the volume. A controller controls a supply of electrical current from an electrical source to the first electrode and to the second electrode. The electrical current supply is controlled to switch from a first mode of operation to a second mode of operation providing electrical current having a reverse polarity during each cycle. The electrical current is supplied at a controlled cycle rate and for a controlled duration. The cycle rate is greater than about 100 hertz and less than about 10 kilohertz.
Abstract:
The present invention relates to fluid purification systems incorporating capacitive deionization cells (110) having a stack of serially connected deionization capacitors (300). The capacitor stack is electrically connected in parallel to a voltage-balancing device that is capable of sharing charge with the deionization capacitors, such that the overall voltage is substantially uniform from the top of the cell stack to the bottom of the cell stack.

Abstract:
A water treatment equipment (100) includes a reaction chamber (104) that includes a pipe (204), a water inlet (206), and a water outlet (208). The pipe (204) includes a first electrode (302) and a second electrode (304). A waveform generator 118 is coupled to the first and second electrodes (302, 304). A controller 112 controls the waveform generator (118). The reaction chamber (104) enables a flow of ozone and water to be treated through the pipe (204).
Abstract:
A modularized fluid purification device and a method for fluid purification are provided that utilizes electrical power to create a high voltage electrostatic field through which the fluid is passed in combination with filtration to remove or neutralize both organic and inorganic contaminants. The electrostatic field may be focused using an electromagnetic field, and one or more filters downstream of the electrostatic field may be charged to attract correspondingly charged contaminants. The electrical power for creating the electrostatic field and/or charging the filters may be generated via a power generation module of the device or from an external source of power. Fluid, such as water, that is passed through the device and purified may, as a result, be suitable for human consumption, as well as agricultural and industrial applications.
