摘要： The invention relates to a method of disinfecting water, comprising adding nonindigenous cupric ions to the water and applying voltage across copper-containing electrodes in contact with the water to generate an antimicrobial effect. The nonindigenous cupric ions are supplied to the water from a cation exchange resin charged beforehand with cupric ions. The invention also relates to a disinfection system installable in a body of water, water supply line or in a circulation line of a water flow, for reducing microbial load of the water, by said method.

摘要： An electrolyzed water spraying device of the present disclosure includes: a short-term maintenance water storage portion (30) that stores liquid and requires short-term maintenance; a long-term maintenance water storage portion (31) that stores liquid and requires long-term maintenance; and a notification controller (43) that notifies each of the timing of the next short-term maintenance and the timing of the next long-term maintenance. The notification controller (43) simultaneously performs the notification of the timing of the next short-term maintenance and the notification of the timing of the next long-term maintenance when the timing of the next short-term maintenance and the timing of the next long-term maintenance are close to each other.

摘要： Methods, systems, and techniques for removing ammonium from ammonia-containing water involve using a stack that has alternating product chambers and concentrate chambers for receiving ammonia-containing water and an acidic solution, respectively, with the chambers being bounded by alternating cation exchange membranes and proton permselective cation exchange membranes. Ammonium moves from the product chambers to the concentrate chambers across the CEMs and protons move from the concentrate chambers to the product chambers across the pCEMs when the stack is in use. An electrolyzer may also be used to convert the ammonium in the concentrate chambers into nitrogen.

摘要： A method and an apparatus for water treatment are disclosed. The method includes steps of associating an iron anode and a cathode with a stream of water, forming an alkaline environment around the iron anode by injecting an alkaline electrolyte solution into the stream of water upstream of the anode. The method also includes generating a solution plasma in the stream of water by applying a potential difference between the iron anode and the cathode.

摘要： An electrolysis nano ion water generator includes a cathode electrolytic tank, an anode electrolytic tank, an ion exchange membrane, and two electrolytic plates. During the electrolysis process, gases are generated and stay between the cathode electrolytic plate and the anode electrolytic plate. By adjusting the distance between the cathode electrolytic plate and the anode electrolytic plate, the gases can be removed from the area.

摘要： A system and method for stretching the discharge of plasma in a liquid utilizes in certain embodiments a first, second and third electrode within a liquid holding container, a gas injection conduit for introducing a gas such as air or oxygen into the container, and a power supply electrically coupled to at least the second and third electrodes. In certain embodiments, a seed plasma generated by a first and second electrode is stretched, and a larger plasma is generated by a first and third electrode. In certain embodiments, a fourth electrode can be used to further stretch the plasma. An increase in gas introduction flow rate can also be utilized to facilitate the stretching of plasma.

摘要： A system to increase the water recovery ratio and efficiently save water in a water treatment and delivery system, particularly for a water treatment system that may be used for water softening, and more particularly for a water treatment system that employs capacitive deionization technology. Stored product water is delivered without the implementation of an additional pump, and the stored product water is used to recover water in a storage tank without having to send water to drain.
