Abstract:
The ozone appliance for the professional dental office and other medical applications introduces dissolved ozone into dental and surgical operatory water lines (21). This dissolved ozone can not only disinfect water and water lines (21); it can also reduce gum bleeding, gingivitis, bad breath, teeth stains and oral bacteria. Additionally, it can aid in wound disinfection in surgery and attack microbial contamination of water from dental and surgical operatory water lines (21) and attached hand pieces (61) and dispensing devices. Further, a unit connected to operatory water lines (21) can give an audible (46) or other alarm (47) if the water becomes unsafe.
Abstract:
An ozonization system (100, 200 or 300) for washing and cleaning objects (71) is described. The system includes a container (110, 210 or 310), an ozonization unit (50) and a diffuser assembly. The container can be a standard kitchen sink, a commercial sink, enclosure (30) or an airtight box (410). The ozonization unit contains a pump (8), an ozone generator (6) and a water separator (162, 262 or 362) which are all controlled by a control circuit (5). The diffuser assembly in one embodiment is a diffuser wand assembly which fits within the standard spray opening (110A) of a kitchen sink. The diffuser tip (129) is inserted into the container and the ozone is diffused into the container through the diffuser tip. In another embodiment, the container has a diffuser plate (214 or 314) spaced apart from the bottom. The ozone is inserted into the gap (213 or 313) between the diffuser plate and the bottom of the container. The ozone is diffused from the gap through the diffuser plate into the container.
Abstract:
The present disclosure provides methods and systems for processing or treating wastewater. The methods of systems of the present disclosure may perform a treatment process on a wastewater stream including gray water and black water to produce a product stream. The product stream may comprise a potable water stream or a stream of treated water with a reduced concentration of one or more contaminant originally included in the wastewater stream.
Abstract:
The invention relates to a pool filtration system for a pool, having a primary filter and a backwash filter, as well as a backwash return conduit, by which, when the pool is being backwashed, the water is directed to the backwash filter, then to the backwash return conduit and back to the pool. The system allows for recycling of backwash water back into the pool.
Abstract:
A two-stage treatment process for destroying per- and polyfluoroalkyl substances (PFAS) in an aqueous stream. The two-stage treatment process uses a combination of multifunctional crystalline molecular sieves, such as zeolites and zeotypes, to separate PFAS from the aqueous stream, catalytically decompose and defluorinate any PFAS molecules, and generate non-toxic waste products that are safe for disposal. The first stage includes adsorption of the PFAS within one of a pair of vessels containing porous, hydrophobic, hydrothermally stable molecular sieves, dehydration of the captured PFAS on the sieves, and catalytic ozonation of the captured PFAS molecules on the dried sieves. The second stage involves catalytic decomposition and neutralization of the ozonation results with one of a pair of vessels including a zeolite-supported CaO catalyst, catalytic oxidation of any toxic CO generated by the decomposition, and an acid wash for regeneration of the spent catalyst.
Abstract:
A faucet for dispensing a fluid includes a spout, a pull-out spray head removably coupled to the spout and including an outlet, and a valve assembly in fluid communication with the outlet. Additionally, the faucet includes a fluid treatment assembly configured to output a treatment into the fluid. The faucet further comprises a first flow path and a second flow path.
Abstract:
A method and apparatus of sanitizing drinking water to be dispensed from a water dispenser having a reservoir includes the steps of providing the ozone gas generator that generates an ozone gas stream, transmitting the ozone gas stream from the generator to the water dispenser reservoir, mechanically breaking up the ozone gas stream inside the reservoir to produce ozone gas bubbles, and using the ozone gas bubbles to disinfect water in the reservoir. The ozone gas stream can be mechanically broken up using a pump such as, for example, an impeller type pump.
Abstract:
A faucet apparatus with an ozonizer may comprise a faucet, a connecting unit, a bubbler and a control sleeve. An outer surface of the connecting unit has at least a first annular groove, and an elastic ring is disposed in the first annular groove. A first threaded segment is formed at a lower end of the connecting unit, and a bore penetrating through the outer surface of the connecting unit is located between the elastic ring and the first threaded segment. By turning the control sleeve to adjust the relative positions between the control sleeve and the connecting unit, the present invention is configured to prevent the control sleeve from being moved by water flow or airflow and to accurately control the use of the ozone thus improving the practicability thereof.
Abstract:
An ozone purification system for wastewater comprising an ozone diffusion reactor installable in or in fluid communication with wastewater collection tanks of septic or other wastewater systems. The reactor includes a pump that circulates wastewater through a gas-liquid mixing device, a contact volume, and a static mixer. The contact volume comprises an elongate length of contact piping and the static mixing chamber is configured to impart turbulence into the flow of the circulated wastewater and ozone gas.
