Abstract:
An embodiment method includes generating a first water product and a sludge (106) of contaminants from water to be treated using an advanced electronic-oxidation process (104); separating (106) the sludge of contaminants from the first water; and filtering the first water product through a membrane structure (110) to produce a second water product.
Abstract:
The present invention relates to a sterilized dental water supply device, and more specifically, to a sterilized dental water supply device is portable such that the sterilized dental water supply device can be connected to any chair unit equipped in a dentist's office at any time when necessary to supply sterilized dental water. According to the present invention, a dental electrolyzed water supply device comprises: a case; a connector insertion unit which is coupled with a handpiece connector in which handpieces necessary for dental treatment are coupled, and has a first fluid pipe that is connected to a pipe, which is formed in said handpiece connector and allows water supplied to said handpieces to flow thereinto; a sterilizing unit which sterilizes water supplied through said connector insertion unit; a sterilized water supply pipe which allows the sterilized water made in said sterilization unit to be supplied to the handpiece; and a connector unit which is formed at the end of said sterilized water supply pipe, has a structure into which one end of a handpiece is inserted, and has a second fluid pipe that is connected to a pipe, which is formed in said handpiece and allows water to be supplied to said handpiece.
Abstract:
The present invention relates to a device and method for purifying a fluid such as an aqueous liquid flow. The purifying device herein comprises: - a container for the fluid; - electrodes placed in the container and operatively connected to an alternating current source; and - an ultrasonic wave generator placed in the container.
Abstract:
A device includes a first electrode and a second electrode spaced from the first electrode to define a volume. An anion exchange membrane and a cation exchange membrane are disposed within the volume. A controller controls a supply of electrical current from an electrical source to the first electrode and to the second electrode. The electrical current supply is controlled to switch from a first mode of operation to a second mode of operation providing electrical current having a reverse polarity during each cycle. The electrical current is supplied at a controlled cycle rate and for a controlled duration. The cycle rate is greater than about 100 hertz and less than about 10 kilohertz.
Abstract:
The present invention relates to fluid purification systems incorporating capacitive deionization cells (110) having a stack of serially connected deionization capacitors (300). The capacitor stack is electrically connected in parallel to a voltage-balancing device that is capable of sharing charge with the deionization capacitors, such that the overall voltage is substantially uniform from the top of the cell stack to the bottom of the cell stack.
Abstract:
The present invention relates to provide a carbon bed electrolyzer (CBE) unit for electrochemical treatment. More particularly the present invention relates to the treatment of recalcitrant wastewater, e.g. from chemical industry. Further the said CBE unit is useful for electrolytic treatment of liquid effluent having very high concentrations of Chemical oxygen Demand (COD), Total Kjeldahl Nitrogen (TKN) and Biochemical Oxygen Demand (BOD), and Total Dissolved Solids (TDS), and for improving biodegradability of the effluent. More particularly, the present invention relates to an electro oxidation process wherein the carbon bed gets regenerated in-situ continuously.
Abstract:
Apparatus for purifying a fluid, which comprises electrode layers (3) facing each other, power supplied to different polarities with spacer layers (5) interposed, and traversed by a flow of fluid to be treated containing ionized particles. The electrode layers (3) and the spacer layers (5) are wound as a spiral around a longitudinal extension axis (Y) inside the suitably cylindrical containment structure (2). The power supply means comprise a pair of collectors (6) that are extended with portions (6') inside the winding connected to the corresponding first internal sides (3') of the electrode layers (3) at the longitudinal extension axis (Y).

Abstract:
A system includes a plurality of stacks and a plurality of converters. Each of the plurality of converters is operable to charge a corresponding stack for adsorbing ions in the liquid. When one of the plurality of stacks is charged or discharged at a first state, one of the plurality of conveners associating with the stack operates in a first mode, and is configured to indirectly convert a first voltage to a second voltage at least by an intermediate stage. When one of the plurality of stacks is charged or discharged at a second state, one of the plurality of converters associating with the stack operates in a second mode, and is configured to directly convert the first voltage to the second voltage.
