The described systems and methods relate to systems for providing a cleaning solution comprising electrolyzed water. While the cleaning systems can comprise any suitable component, in some cases, they include an electrolytic cell and at least one fluid conditioning system that includes a first conduit and a second conduit that are coupled together and are non-concentric with each other. While the fluid conditioning system can be disposed in any suitable location with respect to the cell, in some cases, the fluid condition system is disposed upstream of the cell to provide fluid that passes through the first and second conduits into the cell. In some cases, the fluid conditioning system is disposed downstream of the cell to receive an electrolyzed water produced by the cell. In some cases, the fluid conditioning system is configured to recirculate electrolyzed oxidizing water through an anode compartment of the cell. Other implementations are described.

The present invention relates to systems and methods for cleaning materials, such as flooring and upholstery. In some cases, the systems and methods use an electrolytic cell to electrolyze a solution comprising sodium carbonate, sodium bicarbonate, sodium acetate, sodium percarbonate, potassium carbonate, potassium bicarbonate, and/or any other suitable chemical to generate electrolyzed alkaline water and/or electrolyzed oxidizing water. In some cases, the cell comprises a recirculation loop that recirculates anolyte through an anode compartment of the cell. In some cases, the cell further comprises a sensor and a processor, where the processor is configured to automatically change an operation of the cell, based on a reading from the sensor. In some cases, a fluid flows past a magnet before entering the cell. In some additional cases, fluid from the cell is conditioned by being split into multiple conduits that run in proximity to each other. Additional implementations are described.

Method and apparatus for a low maintenance, high reliability on-site electrolytic generator incorporating automatic cell monitoring for contaminant film buildup, as well as automatically removing or cleaning the contaminant film. This method and apparatus preferably does not require human intervention to clean. For high current density cells, cleaning is preferably performed by reversing the polarity of the electrodes and applying a lower current density to the electrodes, preferably by adjusting the salinity or brine concentration of the electrolyte while keeping the voltage constant. Electrolyte flow preferably comprises water and brine flows which are preferably separately monitored and automatically adjusted. For bipolar cells, flow between modules arranged in parallel is preferably approximately equally distributed between modules and between intermediate electrodes within each module.

A scrubber, an exhaust gas purification system comprising the scrubber, and an air purification method. The treatment water of the scrubber is plasma electrolytic water. The plasma electrolytic water is obtained after water is electrolyzed. The process of electrolysis is carried out in an electromagnetic water treatment device. The electromagnetic water treatment device comprises a cation exchange film, a water flow passage, at least one positive pole panel, at least one negative pole panel, and a magnetic device.

The present invention relates to an apparatus for manufacturing oxygen water or hydrogen water. The apparatus for manufacturing oxygen water or hydrogen water is configured such that oxygen or hydrogen generated from a device for generating oxygen and hydrogen by electrolyzing water is supplied to water using a fluid pump for manufacture of oxygen water or hydrogen water. The apparatus is configured to easily, quickly, and effectively manufacture oxygen water or hydrogen water in a plastic water bottle by dissolving high purity oxygen or hydrogen in source water in the bottle directly. Accordingly, by drinking oxygen water or hydrogen water manufactured thereby, fresh oxygen is supplied to the body, and hydrogen is also supplied to the body and removes harmful reactive oxygen species or reactive carbon species, thereby enabling a healthy life.

To provide an electric cleaning apparatus including a vacuum cleaner that loads an appropriate amount of electrolyzed water and does not reduce convenience in terms of power consumption and lightness. An electric cleaning apparatus includes a vacuum cleaner and a station. The vacuum cleaner comprises: a first reservoir configured to store electrolyzed water; and a first cleaner configured to clean a surface to be cleaned by using the electrolyzed water supplied from the first reservoir. The station comprises: a second reservoir configured to store water; an electrolyzed-water generator that generates the electrolyzed water by electrolyzing the water; and a supply system configured to supply the first reservoir with the electrolyzed water generated with the electrolyzed-water generator when the vacuum cleaner is connected to the station.

An apparatus (100) for producing an acidic aqueous solution includes: an electrodialyzer (110) that has a monovalent ion perm-selective ion-exchange membrane and separates wastewater containing chloride ions and alkali metal ions into electrodialysis concentrated water and electrodialysis diluted water by an electrodialysis treatment; an electrolyzer (120) includes an anode that that electrolyzes the electrodialysis concentrated water to produce an acidic aqueous solution; and a first circulator (13) that circulates at least some of the acidic aqueous solution to the wastewater supplied to the electrodialyzer (110), and that adjusts a pH of the wastewater supplied to the electrodialyzer to 3 to 9.

A water conditioning system for evaporative cooling systems reduces operating costs and microbial contamination by introducing positively charged copper-silver ions into water used as a working fluid. Some of the recirculating water is also passed through a magnetic conditioner to increase its conductivity. By concentrating the total dissolved solids (TDS) in a portion of the water to be expelled, the remaining system water plus new make-up water added contains far lower TDS, reducing health risks, maintenance costs, corrosion, and scaling, and extending service life of replaceable filter elements and system machinery. Recovering non-chemically treated cooling tower bleed water with commercial scale nanofiltration water polishing equipment and returning that polished water back to the cooling tower water basin reduces the make-up water required, and may achieve 70% or greater reduction in sewer fees for tower bleed water, along with increased cycles of concentration further reducing requirement for make-up water.
