Abstract: Contaminants are removed from untreated raw water or discharge water by applying direct current through an array of spaced, alternately charged electrodes positioned within and electrically isolated from a housing to eliminate or minimize clogging of the electrodes with precipitated contaminants. The housing is surrounded with container structure that cooperates with the housing to define an inlet chamber positioned between the source of untreated water and the housing containing the spaced array of electrodes. The container structure further includes an outlet chamber defined between the housing and the container structure for accumulating and draining water treated by the spaced electrode array.

Abstract: A method for the electrochemical remediation of a metal species comprises flowing a contaminated solution comprising a metal species to be removed through an electrochemical cell that includes a working electrode and a counter electrode spaced apart from the working electrode. The working electrode comprises a conductive substrate or current collector with a polymeric coating thereon, where the polymeric coating comprises a semiconducting or redox-active polymer. A reducing potential is applied to the electrochemical cell, thereby inducing the metal species from the contaminated solution to deposit onto the working electrode. After depositing the metal species, a recovery solution is flowed through the electrochemical cell. An oxidizing potential is applied to the electrochemical cell, thereby stripping the metal species from the working electrode and recovering the metal species in the recovery solution.

Abstract: A water conditioning system of an electrodialysis reversal (EDR) water purifier includes a first source water inlet, a second source water inlet, an EDR film stack, a first conductive probe, a second conductive probe, a third conductive probe, a fourth conductive probe, a variable speed pump, a one-way valve, a clean water outlet, a waste water outlet, an electrode A, an electrode B, and a control system module. With the four conductive probes detecting conductivity of water flowing through four ports on two sides of the EDR film stack and by sending detected data to the control system module, the control system module adjusts voltages of the electrode A and electrode B accordingly to instantly increase or decrease removal efficiency of the EDR film stack. Thus, the conductivity of the discharged clean water and the quality of the clean water can be stabilized.

Abstract: Systems and methods for extending life of an apparatus, such as a balloon, using electrolysis. A ballast liquid is carried or harvested and, when desired, is electrolyzed using an on-board electrolyzer to generate lift gas, rather than simply being dumped as traditional ballast. However, the ballast liquid may also be dumped, if necessary. A valve may be provided to enable safe dumping of the ballast liquid. The ballast liquid may be water, a water-methanol mixture, or other suitable ballast liquid. The ballast liquid may be stored in a container associated with the balloon prior to launch or may be harvested from the atmosphere while the balloon is in-flight. Features may be provided to maintain the ballast liquid in a liquid state. The lift gas mixture within the balloon is maintained non-flammable.

Abstract: The present invention relates to a water softening device including: a resin chamber which has an ion exchange resin and softens hard water passing through the ion exchange resin; and electrodes which are arranged by placing the resin chamber therebetween and apply voltages to the resin chamber so as to soften the hard water, and which regenerates the ion exchange resin, wherein the ion exchange resin is a slightly acidic cation exchange resin and/or a weakly alkaline anion exchange resin. The present invention provides the water softening device capable of easily regenerating the ion exchange resin and repeating the softening-regenerating without using chemicals or the like while maintaining the performance of softening water, thereby enabling a continuous use thereof.
