A mixing and dispensing device and method. In particular, the device used by the applied method reduces the risk of chlorine gas formation while providing a stable, effective and safe disinfectant in the form of a hypochlorous add and sodium hypochlorite mixture. The mixing and dispensing device includes a highly concentrated disinfectant and dilutes the concentrate through the device while simultaneously mixing the concentrate with a dilute solution of an organic acid. The two diluted solutions are mixed without production of chlorine gas and to a level of safety before being dispensed to produce the stable, effective and safe neutral pH sodium hypochlorite solution disinfectant in the form of a hypochlorous add and sodium hypochlorite mixture. The mixing and dispensing device can be in the form of a kit for retrofitting into institutions or isolated, remote areas in need thereof or for off the shelf use in the home.

Provided is a liquid supply apparatus which is capable of directly taking in a liquid from a flow channel and appropriately mixing a gas into the liquid when generating-nanobubbles in the liquid using an ultrafine bubble generating apparatus. The liquid supply apparatus comprises a flow channel for a liquid supplied from a liquid supply source and an ultrafine bubble generating apparatus for generating nanobubbles in the liquid. The ultrafine bubble generating apparatus is provided with: a liquid ejector for ejecting the liquid taken in from the flow channel; a gas mixer for pressurizing and mixing a gas into the liquid ejected from the liquid ejector; and a nanobubble-generating nozzle for generating nanobubbles in the liquid by passing the liquid with intermixed gas therethrough. The pressure of the liquid in the flow channel flowing into the liquid ejector from the upstream-side of the liquid ejector is a positive pressure and, between the liquid ejector and the-nanobubble-generating nozzle, the gas mixer pressurizes and mixes the gas into the liquid, which is flowing in a pressurized state toward the nanobubble-generating nozzle.

A mixing funnel for mixing fluids is provided. In one embodiment, the mixing funnel includes a tray having a fluid inlet arranged to receive a primary fluid flow, and first and second fluid passages configured to receive primary fluid flow from the fluid inlet such that the flow is divided to flow along the first and second fluid passages. The first and second fluid passages can be arranged to direct the primary fluid flow to a mixing area. The tray can further include a fluid outlet arranged to receive the primary fluid flow from the mixing area and to deliver the fluid to a container.

A combined heat exchanging and fluid mixing apparatus including a first conduit (44) for guiding a cool fluid through the first conduit and a second conduit (55) for guiding a hot gas through the second conduit. A heat conductive element (2) is arranged between the first conduit (44) and the second conduit (55) for transferring heat from the hot gas to the cool fluid. The apparatus further includes a third conduit (45) for guiding an exhaust fluid. The third conduit (45) comprises an exhaust fluid inlet (46) for introducing an exhaust fluid into the apparatus for mixing of the exhaust fluid with the hot gas and for a chemical reaction of the so formed exhaust fluid/hot gas mixture in the second conduit (55).

A mixing apparatus has a first liquid inlet conduit for a first liquid, a second liquid inlet conduit for a second liquid, a third liquid inlet conduit for a third liquid, and an outlet assembly for feeding a mixture of the first, second, and third liquid from the mixing apparatus. The outlet assembly includes a pair of first outlet openings arranged symmetrically with respect to a center plane of the outlet assembly, a second outlet opening arranged at a center plane, a pair of third outlet openings arranged symmetrically with respect to and along the center plane between the pair of identical first outlet openings and the second outlet opening.
