Abstract: A chemical-free and no-microbe method for pre-treating a broad range of waste waters is presented. The said method involves electrocoagulation (EC) operated in synchronization with electrolytic ozone (EO3). In the combinatory method, each technique not only applies its own treatments, they also create synergistic effects from real-time reactions among the reagents generated by electrolysis. Two refractory waste waters, seawater and tannery effluent, are tested by the combinatory method, EC+EO3, to assess the viability of the said method. Without adjustment, each of the said waste waters is remedied by EC+EO3 from its raw state to a clean condition more effectively and more economically than that can be delivered by the respective prevailing processes of pretreatment for each of the said waste waters.

Abstract: A capacitive deionization (CDI) system for deionizing water is disclosed. The CDI system comprises at least a flow through capacitor (FTC) module, at least a first supercapacitor, at least a second supercapacitor, at least a third supercapacitor and a controller. The FTC module comprises a plurality electrodes for removing ions from water flowing between the electrodes under an electric field applied between the electrodes. The first supercapacitor is connected between the potential source and the FTC module for amplifying energy provided by the potential source. The second supercapacitor is connected to the FTC module for receiving energy from the FTC module for regenerating the electrodes of the FTC module. The third supercapacitor is adapted for exchanging energy with the FTC module for regenerating the electrodes of the FTC module. The controller is adapted for regulating deionization rate of the water and regeneration of the electrodes of the FTC module.

Abstract: All pollutants dissolved or existed in water can be grossly classified as ionized and neutral species. The former includes inorganic and organic ions, while the latter contains inorganic molecules, organic molecules and organisms. Using flow through capacitor for performing capacitive deionization (CDI), the ionic contaminants can be effectively and economically removed from water. Whereas the neutral contaminants are not retained in the static electric field of CDI, they can be decomposed upon flowing through an electrolytic ozonator. Either gaseous or ionic products will be generated at the ozone treatment, and the ionic byproducts can be subsequently removed by CDI. By integrating the electrolytic ozone reactor with flow through capacitor, the O3/CDI hybrid technique becomes a total solution for eliminating hazardous materials in water.
