Abstract:
A fluid treatment apparatus comprises an electrochemical cell having fluid orifices to receive input fluid and release output fluid, the input fluid having a first level of a microorganism. First and second electrodes are about a water-splitting membrane in the electrochemical cell. A valve controls the flow of fluid through fluid orifices of the electrochemical cell. A power supply supplies a current to the first and second electrodes. A control module comprises program code to operate the valve to flow the input fluid into a fluid orifice of the electrochemical cell and provide a residence time of the fluid in the cell of at least 0.05 minutes, while controlling the power supply to supply to the first and second electrodes, a current having a current density of from about 0.01 to about 20 mA/cm2.

Abstract:
This invention relates to a process for modifying a strong acid/salt solution or strong base/salt solution, and to the resulting modified solution. The modifications of this invention stably increase the reactivity of the solution while maintaining the non-corrosive and dermal-friendly characteristics of the solution. In particular, the inventive composition does not injure or irritate skin, as might an unmodified strong acid or strong base, but retains sufficient strong acid or strong base qualities that it tends to weaken intermolecular bonds and break covalent bonds. By way of example, combining the inventive composition with a biocide agent may result in an effective anti-microbial, anti-bacterial, or anti-viral solution that is non-corrosive and dermal friendly.
Abstract:
Devices for treating water are provided with a varistor to protect the circuitry within such devices against excessive voltage surges and/or transient voltages. The varistor is incorporated into the circuitry in such a way that, when triggered by a high voltage spike (e.g., power surge), the varistor shunts the current created by the high voltage spike away from other sensitive components of the circuitry. Methods for treating water using devices that incorporate the varistor are also provided.
Abstract:
Sludge is treated in a treatment chamber by providing a pair of electrodes in the treatment chamber and applying an electrical current between the electrodes such that one of the electrodes functions as an anode and one of the electrodes functions as a cathode in proximity to the outlet. A flow of water is induced from the sludge towards the outlet by the electrical current. An ion exchange textile comprising exchangeable functional groups grafted thereon is located in proximity to at least one of the electrodes such that the ionic forms of the metals are exchanged with the functional groups on the ion exchange textile. Accordingly the sludge is dewatered and metals in the sludge are captured commonly in the treatment chamber while the electrical current simultaneously inactivates pathogens in the treatment chamber.

Abstract:
An electronic water treatment apparatus includes an electronic impulse generator and control box attached to a power source. An impulse chamber includes a cylindrical anode rod inside a tubular cathode and is connected to the impulse generator and control box with a low-voltage cable which is no more than about six feet long. The impulse generator and control box supply about 16 v DC power and 120-180 milliamps to the impulse chamber at between 2300 and 5200 Hertz. The discharge frequency within the impulse chamber automatically varies with the conductivity of the aqueous solution within the impulse chamber. The impulse generator and control box supply power with a waveform that includes about a two microsecond break between each positive and negative pulse to prevent corrosion of the electrodes and create the aragonite form of calcium carbonate instead of the calcite form.

A system and process for de-halogenating ballast water before releasing the ballast water from the vessel. In one embodiment, the system comprises a means for measuring the halogen content of the ballast water, a reducing agent source in fluid communication with the ballast water, and a means for controlling the amount of reducing agent supplied to the ballast water. In one aspect, the means for measuring the halogen content comprises one or more oxidation/reduction potential analyzers. In another embodiment, the system comprises one or more hypochlorite electrolytic cells for generating hypochlorite to treat the ballast water.One embodiment of the process for de-halogenating ballast water comprises measuring the oxidation/reduction potential of the ballast water and adding one or more reducing agents to the ballast water to de-halogenate the ballast water in response to the measured oxidation/reduction potential. In one aspect, the oxidation/reduction potential is modulated so that excess reducing agent is present in the ballast water.

An electrocoagulation treatment device includes a plurality of spaced reaction plates disposed within a reaction chamber. A voltage is applied to selected reaction plates to create an electrical field within the electrocoagulation chamber. The plates are arranged vertically which induces a vertical flow of liquid through a device. The device includes various embodiments adapted for use as a large industrial unit, a portable unit or for use within the home. The voltage and amperage of the electrical field chamber may be adjusted by placing selected reaction plates in electrical contact with the voltage source. One embodiment is especially adapted for treatment of oil slop to remove water from the oil, and for treatment of seawater to desalinate the same.
