摘要： A water softening device includes a container configured to contain water, first and second electrodes arranged in fluid communication with the water, and a power source. The first electrode includes a conversion material that has a first composition and a second composition coexisting with the first composition. The first composition includes calcium ions bonded thereto and the second composition includes sodium ions bonded thereto. The power source supplies current in a first operating state such that the second composition exchanges sodium ions for calcium ions in the water to generate a soft water solution. The first and second electrodes are connected in a second operating state such that the first composition exchanges calcium ions for sodium ions in the water to generate a wastewater solution. The conversion material undergoes a reversible conversion reaction to convert between the first and second compositions within the water stability window.

摘要： An electrochemical cell according to the present disclosure includes a casing provided with an inflow port and an outflow port, a bipolar membrane laminated body in which two or more bipolar membranes are laminated so as to be opposed, electrodes disposed so as to sandwich the bipolar membrane laminated body, and a first diffusion member disposed between the inflow port and the bipolar membrane laminated body, and provided with through holes communicating between the inflow port and the bipolar membrane laminated body. The first diffusion member is formed such that each of the through holes provided in a peripheral edge portion has a larger opening area than an opening area of the through holes provided in a central portion. This can uniformize a flow of water, so that water treatment can be efficiently executed.

摘要： There is provided a system and method for regulating conductivity of cooling water in a recirculation route of a cooling water recirculation system through which the cooling water is circulated for removing scale from the cooling water. The system comprises an electrolytic device connectable to the cooling water recirculation system for performing electrolysis on the cooling water and a controller. The controller is for controlling the electrolysis of the cooling water in an electrolytic chamber of the electrolytic device for depositing ions in the cooling water as scale on the surface of one of a pair of electrodes of the electrolytic device and for dislodging the scale deposited thereon, monitoring a value of voltage and a value of current between the pair of electrodes, calculating a conductivity of the cooling water based on the monitored values of voltage and current, and regulating an amount of discharge of the cooling water from the electrolytic chamber based on the calculated conductivity of the cooling water, whereby the scale is removed with the cooling water that is being discharged and the cooling water that is being electrolyzed is directed back to the recirculation route of the cooling water recirculation system for circulation.

摘要： A side-stream particle precipitator system for the breakdown and removal of bio-materials and suspended solids in water cooling systems using a plurality of ionizer treatment units utilizing electric and electro-magnetic fields and a mechanical vortex precipitating system to remove particulate materials contained in the water complex as suspended solids. The system also uses high voltage electrodes for charging the water complex to breakdown laminar flow at the conduit walls to mechanically dislodge any build-up of bio-materials or chemical compounds along the walls resulting in an increase in thermal conductivity.

摘要： Method for treating a fluid containing ionized particles, by means of an apparatus provided with a hydraulic circuit (100) intercepted by an immiscible storage tank and by a cyclically regenerating filtering unit (3, 3A, 3B), connected in parallel to the tank. The following are provided for: a supply pipe connected to the hydraulic circuit (100) upstream of the immiscible storage tank for introducing fluid to be purified and an extraction pipe (9) connected to the hydraulic circuit (100) downstream of the filtering unit (3, 3A, 3B) for conveying purified fluid to the user. The method cyclically comprises a circulation step, in which the fluid circulates through the filtering unit (3, 3A, 3B) and the immiscible tank (2), accumulating in the latter an operating amount of fluid with increasing concentration of ionized particles, and a production step in which an operating amount of fluid to be purified is introduced into the hydraulic circuit (100) by the supply pipe such that an equivalent operating amount of fluid with increasing concentration of ionized particles previously accumulated in the tank is forced to exit from the tank itself and pass through the filtering unit (3, 3A, 3B) in order to be further purified and then drawn by the extraction pipe (9).

摘要： Systems and methods for treating water are provided. The systems and methods may utilize an electrochemical water treatment device comprising ion exchange membranes. In certain systems and methods, a concentrate stream and a dilution stream may be in fluid communication with ion exchange membranes. The ion exchange membranes may be configured to provide a ratio of a pH of the concentrate stream and a pH of the dilution stream to be less than about 1.0. In some instances, the LSI of the concentrate stream may be less than or about 1.0. In certain instances, the electrochemical water treatment device does not require a reverse polarity cycle.
