An electro-chemical activation (ECA) system includes an anode chamber, a cathode chamber, and a neutralization chamber. The anode chamber includes an anode configured to convert water having an alkaline-metal chloride into an anodic electrolyte that includes hypochlorous acid. The cathode chamber includes a cathode configured to convert water into a cathodic electrolyte. The neutralization chamber includes a neutralization cathode configured to remove protons from the anodic electrolyte after it leaves the anode chamber. The ECA system is configured to recirculate the anodic electrolyte back through the anode chamber and the neutralization chamber at least one more time to produce a concentrated chlorine solution. The ECA system is further configured to recirculate the cathodic electrolyte back through the cathode chamber at least one additional time to produce a concentrated alkaline solution.

A Dielectric Barrier Discharge system controller for controlling a fluid treatment by a Dielectric Barrier Discharge system is provided. Therein, the strength of an effect caused by a discharge created by the Dielectric Barrier Discharge system is monitored, and the generation of high-voltage pulses by the high-voltage pulse generator is controlled. The controlling of the generation of the high-voltage pulses is adapted based on the received sensor data.

A portable hydrogen-containing ozone water humidifier including a housing with a mist outlet, a water tank for storing water, a hydrogen-containing ozone water generator, an ultrasonic atomizer for converting water into mist, a rechargeable battery and an electronic controller is revealed. An outlet pipe is connected to the bottom of the water tank and the hydrogen-containing ozone water generator is disposed on the outlet pipe for hydrolysis of the water to generate oxygen and ozone gas at an anode plate and hydrogen gas at a cathode plate and further get disinfectant water formed by ozone water mixed with hydrogen-rich water while the ultrasonic atomizer is arranged at an outlet end of the outlet pipe. The rechargeable battery provides power to the electronic controller, the hydrogen-containing ozone water generator, and the ultrasonic atomizer for driving them to work. The humidifier is compact and easy to carry.

An automated total organic carbon analyzer is described. Embodiments of the system include two features, namely the development of a selective oxidation reactor to oxidize organic contaminants to their corresponding organic acids, and the measurement of the organic acids individually by chain length using an electroanalytical detector. Combining this electroanalytical approach with sequential detection capabilities (such as spectrophotometry) can expand the instrument capabilities by providing organic contaminant speciation. The described reactor performs selective oxidation of organic carbon to organic acids followed by complexation with a proprietary ligand, then selective detection using electroanalytical accumulation and desorption of organic acids performed at an electrode surface.

A method for treating wastewater having one or more of suspended solids, dissolved solids, biological oxygen demand includes solids filtration followed by a bi-polar/bi-directional flow through ionic module fitted with anionically/cationically charged plates followed by a sub-sonic resonance module followed by another bi-polar/bi-directional flow through ionic module followed by a ultra-sonic resonance module followed by one or more anion/cation collection membrane modules. Recycle is provided in each step, wherein each step may be repeated, and wherein one or more of the steps can be bypassed.

A hydrogen gas dissolving apparatus 1 has a hydrogen supply unit 2 capable of supplying hydrogen gas, and a hydrogen gas dissolution module 6 for bringing the hydrogen gas supplied from the hydrogen supply unit 2 in contact with and dissolved in water. The hydrogen gas dissolution module 6 has a supply port 62 to which the hydrogen gas is supplied, a hydrogen chamber 63 communicating with the supply port 62 and filled with the hydrogen gas supplied from the supply port 62, and an exhaust port 64 communicating with the hydrogen chamber 63 and discharging the air in the hydrogen chamber 63. The exhaust port 64 is located in a lower part of the hydrogen chamber 63.

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 senor 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.

Unwanted material in water, such as Legionella and scale, may be treated using a combination of technologies. Components of each technology may be controlled using a databus, such as an Internet-of-things (IoT) databus. An additional advantage of the treatment technologies is an increase in the efficiency of heat transfer components, such as cooling towers, and a related reduction in carbon footprint.

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.
