Abstract:
A method for treating a wastewater stream containing organic material or inorganic material comprising passing the wastewater stream to an anode or a cathode of a bioelectrochemical system to thereby alter the pH of the wastewater stream to: a) reduce the pH of the stream passed to the anode to minimise or suppress precipitation of dissolved cations; or b) increase the pH of the stream passed to the cathode to produce an alkaline stream; or c) reduce the pH of the stream passed to the anode to produce an acid containing stream. In one embodiment, a caustic soda solution is produced at the cathode and recovered for storage and subsequent use.
Abstract:
A water body self-generating electrolytic reduction module is applied to a water body containing oxidizing substances. The water body self-generating electrolytic reduction module includes a self-generating unit and an electrolysis unit. The self-generating unit is coupled to the electrolysis unit. When circulating in a water transmission pipeline, the water body drives the self-generating unit to generate an electric power and deliver the electric power to the electrolysis unit. Upon receiving the electric power, the electrolysis unit performs electrolysis on the water body circulating to the electrolysis unit, so that a reduction reaction occurs to the oxidizing substances in the water body.
Abstract:
There is disclosed a treatment process of wastes containing organic molecules with electron-withdrawing groups on conjugated unsaturated bonds, for instance belonging to aromatic rings. The process comprises an electrochemical reduction step and a simultaneous or subsequent oxidation step, optionally also of electrochemical nature.
Abstract:
Detailed is electricity generation for powering devices associated with swimming pools or other structures utilizing recirculating fluid. The recirculating fluid is used to produce electricity for direct or indirect supply to electrical devices. Turbines may be placed in by-pass channels so as to have access to some fluid flow yet not unduly disrupt main flow of the recirculating fluid.
Abstract:
The present invention relates to an agricultural water-recycling system comprising an iron (Fe)-ionizing module and a method of recycling agricultural water using the same, and more particularly to an agricultural water-recycling system comprising an iron (Fe)-ionizing module and a method of recycling agricultural water using the same, in which phosphorus (P) contained in effluent from a sewage treatment plant is removed by using the iron (Fe)-ionizing module comprising an iron (Fe)-ionizing electrode consisting of an iron plate serving as a cathode and a titanium plate serving as an anode and an electrode-washing device. According to the present invention, an effluent treatment process of a sewage treatment plant and an electrode washing process needed for iron ionization can be simultaneously performed, the iron ionization is controlled depending on the concentration of phosphorus contained in the effluent, thereby improving effluent treatment efficiency.
Abstract:
A continuous method for the treatment of a spent aqueous caustic stream used to scrub a hydrocarbon process stream to remove oxidizable sulfur-containing compounds includes: a. mixing an oxidizing hypochlorous acid stream produced from an aqueous brine solution with the aqueous caustic stream to form a reactive mixed feedstream; b. contacting the reactive mixed feedstream with at least one catalyst to promote the oxidation of the sulfur-containing compounds and the neutralization of the sodium hydroxide; and c. recovering a neutral treated product stream comprising aqueous sodium sulfate, sodium carbonate and sodium chloride that is odorless, non-toxic and environmentally acceptable for discharge into the sea or into a conventional sewage treatment system. Preferably, the hypochlorous acid is produced by an electrolyzer that also produces a (1) hydrogen stream that is directed to a PEM fuel cell to generate at least a portion of the electrical power requirement of the electrolyzer, and (2) water that is combined with fresh sodium hydroxide from the electrolyzer to form a fresh caustic stream for use in scrubbing the hydrocarbon process stream.

Abstract:
An electrolyzed water generating and spraying device that allows generating electrolyzed water in a short time, and allows spraying non-deteriorated electrolyzed water immediately after being generated. The electrolyzed water generating and spraying device has a container, and housed therein, an electrolytic cell to generate electrolyzed water through electrolysis of an electrolytic solution by an electrode, a manual spray pump to manually spray the electrolyzed water generated in the electrolytic cell, and a power supply to energize the electrode. A tank to store the electrolytic solution and the electrolytic cell are provided independently in the container, such that the electrolytic cell is disposed below the tank, and the tank and the electrolytic cell communicate with each other via a communicating passage. Part of at least the electrolytic cell in the container is transparent. Also, the volume of the electrolytic cell is set to be smaller than the volume of the tank.
