An apparatus has a hub including a water inlet for receiving source water, a water outlet for discharging ozonated water, and an interface between the water inlet and the water outlet. The apparatus also has a cartridge including an electrolytic cell for ozonating the source water. The electrolytic cell has a cathode, an anode comprising diamond, and a membrane between the cathode and the anode. The electrolytic cell is configured to flow source water through both the cathode and the anode. The cartridge further includes at least one cartridge port for removably coupling with the interface on the hub. The at least one cartridge port and the interface are configured to flow source water from the hub into the electrolytic cell and to flow ozonated water from the electrolytic cell into the hub.

A hydrogen and oxygen generator has two end plates, at least two electrode assemblies defining an electrolysis chamber therebetween and being disposed between the two end plates, and at least one fastener connecting the two end plates together. Each electrode assembly has a plate defining an electrode portion having a perimeter and defining inlet and outlet apertures, an inlet insulating grommet disposed in the inlet aperture and covering an edge thereof, an outlet insulating grommet disposed in the outlet aperture and covering an edge thereof, and an insulating band disposed around the electrode portion and covering an edge of the electrode portion defining the perimeter. The insulating bands of the at least two electrode assemblies abut each other. The inlet and outlet apertures of the at least two electrode assemblies fluidly communicate with the electrolysis chamber. An electrode assembly and a hydrogen and oxygen generation system are also disclosed.

Systems and processes for removing and purifying bromide from an aqueous bromide solution are described. Electrochemistry is used to either convert bromide to bromine to allow its extraction in an organic phase, or to cause deposition of bromine onto an electrode. In either case, once removed from the aqueous bromide solution, the bromide can be recovered and purified.

Articles of manufacture possessing corrosion resistance characteristics are described, in particular for use in the chlor-alkali and other industries. The articles are formed from a resin composition, e.g., a cyclic olefin composition, polymerized with a Group 8 olefin metathesis catalyst. In particular aspects, an electrolytic cell component, such as a cell cover for use in the electrolysis of brine, may be formed from the resin composition. Among other benefits, such articles provide improved corrosion resistance compared to articles molded from other resin compositions, such as fiberglass reinforced polyesters and vinyl esters, and two-component dicyclopentadiene (DCPD) resins comprising molybdenum or tungsten pre-catalysts.

A multifunctional mopping machine includes a handle, a body and a main machine. The body includes a mounting base, and a housing provided with a cleaning assembly; the body is detachably connected to the mounting base; the main machine includes a negative pressure assembly and a power supply assembly; the power supply assembly, the negative pressure assembly and the cleaning assembly form a cleaning mechanism; and a water tank for supplying water to the cleaning assembly, and a sodium hypochlorite electrolysis generator are arranged on the mounting base. An ultraviolet sterilizing lamp facing the ground to be cleaned is arranged on the housing. A tail end of a dust collecting hose communicates with a negative pressure end of the main machine, and collects both dirty water and dust on the floor, so as to ensure no stain left on the floor, satisfying present floor washing requirements.

An electrochlorination apparatus is provided for generating a sodium hypochlorite solution. The apparatus includes an electrolytic cell and a brine tank that is located above the electrolytic cell. The brine tank is adapted to supply a predetermined volume of a saturated brine solution to the cell via a gravity feed. A flow meter is provided for connection to a water supply and adapted to supply water to the electrolytic cell via a valve. A controller controls operation of the valve whereby a predetermined volume of water as measured by the flow meter is also supplied to the cell in combination with the brine solution so that the cell operates to produce a sodium hypochlorite solution of a predetermined concentration.

An orientation independent delivery device. The delivery device includes a gas chamber, a delivery chamber, a gas cell, and a delivery aperture. The gas chamber includes a gas-side rigid portion and a gas-side flexible barrier. The gas-side flexible barrier is sealed to the gas-side rigid portion. The delivery chamber includes a delivery-side rigid portion and a delivery-side flexible barrier. The delivery-side flexible barrier is sealed to the delivery-side rigid portion and is oriented adjacent to the gas-side flexible barrier. The gas cell is coupled to the gas-side rigid portion of the gas chamber. The gas cell increases a gas pressure within the gas chamber to expand the gas-side flexible barrier. Expansion of the gas-side flexible barrier applies a compressive force to the delivery-side flexible barrier allowing a delivery material to escape from the delivery chamber.
