A water use management system may be installed in a setting that contains a primary infrastructure for water use to provide an alternate, modular infrastructure for water use. Fresh water used at various points of use, such as a shower or sink, may be diverted into the modular infrastructure prior to draining into the primary infrastructure. Once diverted, the precedent use water is received at a reservoir system where it is treated for a subsequent use. Treatment may include filtration and/or chemical treatment, and may be based upon sensor feedback from the reservoir system. Once treated, the water is ready for subsequent use and may flow from the reservoir system, via the modular infrastructure, to a subsequent point of use, such as a toilet.

The present invention relates to a sanitization unit (1), for sanitizing a liquid to be delivered to a beverage preparation unit (102) in order to prepare a beverage, the sanitization unit (1) comprising: —an irradiation chamber (2) configured to receive an amount of liquid, and—an irradiation device (4) configured to emit sanitizing radiations into the irradiation chamber (2) so as to sanitize the liquid in the irradiation chamber (2), wherein the irradiation chamber (2) comprises: —a liquid inlet (10) located in a lowermost region of the irradiation chamber (2) for introducing the liquid into the irradiation chamber (2), —a liquid outlet located in an uppermost region of the irradiation chamber (2) for discharging the introduced liquid out of the irradiation chamber (2), and—an air inlet (14) located in the uppermost region of the irradiation chamber (2) so as to let air enter the irradiation chamber (2) and evacuate the liquid out of the irradiation chamber (2) via the liquid inlet (10) and/or via the liquid outlet (12).

A customizable multi-stage fluid treatment assembly typically includes a connector, a plurality of cartridges, and a cap. The plurality of cartridges have a treatment medium spaced within an interior volume of the individual cartridges, between the ends thereof. The ends of the plurality of cartridges are configured to receive a fluid, bring the fluid into operative contact with the treatment medium, and dispense the fluid from the opposing end of the cartridge. The connector is coupled with one end of the plurality of cartridges and has an inlet and an outlet for receiving and dispensing the fluid to and from an appliance. The cap is coupled with the other end of the plurality of cartridges, enclosing the fluid treatment assembly, which is configured to be received in a cavity of an appliance. The cartridges of the plurality of cartridges may be individually replaced with cartridges to meet customized needs.

A water purification device includes a housing having an outlet for dispensing purified water; a filtration system for purifying water, and a pump mounted to the housing and fluidly coupled between the filtration system and the outlet; and a bladderless accumulator coupled to the pump for accumulating the water. The pump is mounted to the housing via a pump mount that is suspended above the housing. The combination of a bladderless accumulator and pump mount ensures that pulsations generated by the pump are greatly reduced.

A water purifying filter has a cylindrical inner housing to receive a filter therein, and an outer housing to receive the inner housing. The inner housing and the outer housing are spaced apart from each other to form an insulation space configured to suppress heat transfer and to reduce the filter freezing inside the inner housing.

The present inventive concept relates to a method for optimizing water usage in a device utilizing water for a group of cleaning procedures, wherein the device comprises a sensor arrangement (518) and a data processing device, wherein the method comprises the steps of: determining a first substance content (400a) of first cleaning phase water from a first cleaning phase of the cleaning procedure (428) using the sensor arrangement (518); in the data processing device, receiving data comprising a target substance content interval requirement (844) of at least one of a plurality of cleaning phases (314); in the data processing device, comparing the first substance content to the target substance content interval requirement (844); and forming cleaning phase water to be used in the at least one of the plurality of cleaning phases (314) by transferring the first cleaning phase water to the at least one of the plurality of cleaning phases (314) based on the comparison.

A tankless water heater including a water inlet, a water outlet, a conductivity sensor, a temperature sensor, and a heating chamber connected to the water inlet and the water outlet wherein the heating chamber is configured to heat a flow of water received from the water inlet and output the flow of water to the water outlet. The water heating system can further include a controller communicably coupled to the conductivity sensor and the temperature sensor, where the controller calculates an adjusted conductivity of a flow of water through the water heater.

A cleaning device including a disinfection water supply portion to supply cleaning water with a dissolved disinfection component, and a bubble generation portion to contain bubbles into the cleaning water on a downstream side of the disinfection water supply portion.

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.

The embodiments of the present disclosure provide an electrode plate, an electrolysis apparatus, and a laundry treatment device. Multiple through holes penetrating the electrode plate in the thickness direction of the electrode plate are formed in the electrode plate. The density of the through holes in the electrode plate is 1-10/cm.sup.2. According to the electrode plate in the embodiments of the present disclosure, on the one hand, because the density of surface charge at the junction of the inner wall of the through hole and the surface of the electrode plate is larger, and the electric field intensity nearby is higher, the electrolysis efficiency can be greatly improved, more active substances such as hydroxyl radicals and active chlorine can be generated, and more microbubbles can also be generated, which can improve the sterilization, cross color prevention and washing effects.
