The present disclosure provides systems and methods for increasing the oxygen concentration of a water supply. The systems generally include a water supply and an electrolyzer module that generates oxygen to be added to the water supply. The methods generally include generating oxygen using an electrolyzer module and adding the generated oxygen to a water supply.

A disinfection device for a trapped-liquid comprising of a drain trap for a liquid flow having an inner surface to trap a volume of the trapped-liquid and a helical coil capable of generating metal ions to eliminate biological cells attached to said drain trap. An electric valve is connected to a tap water and the helical coil and a power supply provides a current and a voltage to the helical coil for a period of ionization and a sensor system installed in the drain trap to sense flow of a liquid through the drain trap. A timer system to determine the length of a stagnant-time that the trapped-liquid is stagnant in the drain trap; and to determine the length of an ionization-time for the period of ionization.

An automated descaling system can be integrated into a tankless water heater or can be a separate system that is connected to a tankless water heater. The automatic descaling system comprises a cleaning media chamber and a valve with a motor. The descaling system can be set on an automatic cleaning schedule.

Resources, such as water, energy, power, amount of de-scaling chemicals, device lifetimes, data analytics and system depreciation may be conserved through the use of dual-field electric and magnetic probes that create and apply electromagnetic fields to liquids, such as water.

An air fed mycoplasma device includes an array of elongate microchannels formed in a plastic or ceramic having tolerance to ozone and other radicals formed when plasma is generated from air in the microchannels. The microchannels include inlets configured to accept an air feed, and outlets configured to direct plasma jets toward a surface (which may be flat or internal to a pipe, for example) or object. An array of electrodes within the plastic/ceramic housing is configured to ignite and maintain plasma in the microchannels and is isolated by the dielectric from the microchannels. A supply intake for is configured to providing a plasma medium into the microchannels.

A water processor is provided for processing or conditioning water to be distributed downstream of the water processor. The water processor includes a housing having an inlet and an outlet opposite the inlet. The water processor includes a conditioning element disposed inside of the housing between the inlet and outlet. The conditioning element includes a plurality of plates having apertures with sharp edges to direct the flow of water and facilitate splitting of small gas bubbles into even smaller nano-bubbles. The plurality of plates include a first plate having a first configuration of apertures and a second plate having a second configuration of apertures. The first and second plates are disposed in alternating spaced arrangement along the longitudinal axis of the housing. The second configuration is different from the first configuration such that the flow path through the water processor is circuitous or substantially indirect.

A method and apparatus are provided for dosing biocide into fluid. A biofilm sensor configured to measure an amount of biofilm on the biofilm sensor is used. A method identifies, if present, in a data set representing measurement over time by the biofilm sensor a minimum and an inflection point and, if identified. According to some embodiments, dosing of biocide is determined to be effectuated when an inflection point has been identified occurring time wise after an identified minimum.

A cartridge for use in a water purification apparatus and a water purification method for maintaining a water quality supply are provided. The cartridge comprises an elongated tubular body having first and second ends comprising a fluid inlet and a fluid outlet, and an internal chamber extending between the first and second end. The first end includes an end cap having a first opening in fluid communication with the body. A disinfectant material is disposed in the internal chamber of the body. Filters are disposed in the elongated tubular body adjacent to the first opening and adjacent the second end of the elongated tubular body and are in fluid communication with the internal chamber and the fluid outlet. The second end of the elongated tubular body comprising an exterior surface having a tapered portion and a linear portion adjacent to the tapered portion.

A water purifier for home use, irrigation systems used for crop cultivation or the pharmaceutical industry includes a water inlet for a water to be purified and a water outlet for a purified water. A water treatment chamber is fluidly connected to the water inlet and the water outlet. The water treatment chamber is confined by a chamber wall. The water purifier includes a high-voltage plasma unit for generating a cold plasma within the water treatment chamber. The plasma unit has a first electrode and a second electrode. The first electrode is arranged inside the water treatment chamber such that, during use of the water purifier, it is contacted by the water. The second electrode is disposed spaced apart from the first electrode and electrically insulated therefrom by a dielectric. The water purifier further relates to a water purification system.

A method for disinfecting a water system of an aircraft includes the introduction of damp hot air at an inlet of the water system by a ground service unit; flushing of the damp hot air from the inlet through water pipes of the water system to an outlet of the water system; and extraction of the damp hot air at the outlet; wherein the damp hot air is flushed into the inlet and out of the outlet over a predefined disinfection period, and wherein the damp hot air has a temperature between 60° C. and 80° C.
