Abstract:
An embodiment is a method and apparatus to provide de-ionization. First and second conductive porous membranes are placed between a feed channel having a feed flow and first and second concentration channels having first and second concentration flows to separate the feed channel from the concentration channels. Cathode and anode electrodes are placed on external sides of the concentration channels. A voltage supply distribution network provides independent voltages across the channels to cause movement of ions in the feed and concentration flows toward the electrodes.
Abstract:
The present invention relates to the technical field of environmental protection, especially relating to an efficiently-inactivating and energy-saving method for processing ship ballast water, which comprising the following processes: A) a filtering process, in which ship ballast water is filtered to remove the large grained organisms and solids; and B) a sterilizing process, in which the filtered water flows through a sterilization processing unit to have the organisms and bacteria in the water killed. Correspondingly, the present invention also discloses a system for processing ship ballast water, which has advantages as follows: low energy consumption, high efficiency, convenient installation simple and no pollution after processing.
Abstract:
The object of the invention is to provide a method for cleaning circulation water, which reduces the cost of operation and maintenance as much as possible, without a cumbersome cleaning operation such as by detaching electrode plates from an electrolysis cleaning tank and removing scale from inside the tank, and to provide a device used in this method. Accordingly, the present invention provides a method for cleaning circulation water, comprising the steps of flowing circulation water to be cleaned between electrode plates placed in a face-to-face manner between one another; and applying DC voltage between the electrode plates, allowing one or more metal ions contained in the circulation water to be precipitated onto the negative electrode plates by electrolysis, to clean the circulation water, wherein the electrode plates used are made of titanium plates, and wherein a desired amount of current flows, while an anodized oxide coating formed on the surface of the positive electrode plates is compulsively subject to dielectric breakdown by increasing the voltage applied to the anodized oxide coating. FIG. 1 is a representative drawing.
Abstract:
A filter unit may include an electrode structure, a fluid-purifying flow path, and a pH adjusting chamber. The electrode structure may include a cathode, a cation exchange membrane, an anion exchange membrane, and an anode in that order. The fluid-purifying flow path may be at least one of a path in the cathode, between the cathode and the cation exchange membrane, between the anion exchange membrane and the anode, and in the anode. The fluid-purifying flow path may include an adsorption function. The pH adjusting chamber may be between the cation exchange membrane and the anion exchange membrane. The pH adjusting chamber may be configured to control the pH of the fluid in the fluid-purifying flow path.
Abstract:
An apparatus to remove ions, the apparatus comprising an inlet to let water in the apparatus, an outlet to let water out of the apparatus, a capacitor, and a spacer to separate a first and a second electrode of the capacitor and to allow water to flow in between the electrodes. The apparatus comprises a regeneration mode controller configured to control, during a regeneration mode in which ions previously attracted to the capacitor are released in a waste water stream, one or more of: the electrical current flowing to the capacitor; the voltage on the capacitor; and/or the water flowing in between the electrodes. The regeneration mode controller is constructed and arranged to control one or more of the electrical current, the voltage, and/or the water flow during the regeneration mode such that scaling is reduced or minimized in the apparatus.
Abstract:
A water purification apparatus is provided. The apparatus includes a casing and an electrode array. The casing has an outer surface, a substantially annular inner surface, and a water flow passage chamber surrounded by the substantially annular inner surface, the water flow passage chamber providing an outer annulus region and an inner central region. The electrode array features at least four electrodes in adjacent relationship to one another and circumferentially spaced apart from another about the outer annulus region, each electrode having a respective first planar surface and a respective second planar surface facing and substantially parallel to the respective second planar surface and the respective first planar surface of the adjacent electrodes on opposite sides thereof.
Abstract:
A portable apparatus for treating polluted water by electrocoagulation. The apparatus comprising at least two electrodes (1,2). The apparatus also includes a housing (4), electrically isolated from the at least two electrodes (1,2), to which the at least two electrodes (1,2) are fixed spaced apart from one another. When the at least two second electrodes (1,2) are at least partly submerged in the polluted water and provided with an electrical potential, one of the at least two electrodes (2) is sacrificial so as to provide ions to the polluted water.
