Abstract:
A method and apparatus are provided for a water treatment system that includes both filtration and ultraviolet disinfection elements in a single unit. Various embodiments include a complete treatment system having replaceable filter elements or granular filter media and ultraviolet disinfection within a single vessel. A control valve controls flow through the system in filtering, backwashing, cleaning, and rinsing modes of operation. Other embodiments include couplings that may be adapted to new or existing treatment systems to provide ultraviolet disinfection to a vessel containing replaceable filter elements or granular filter media. The coupling is adapted to receive a control valve assembly that controls flow through the vessel in filtering, backwashing, cleaning, and rinsing modes of operation.
Abstract:
A 3-Dimensional golf game having a horizontal surface, a vertical surface, and a curvilinear surface that interconnects the horizontal and vertical surfaces, wherein at least the vertical surface includes one or more ball-receiving cups. The game of skill is played by one or more players putting or striking a golf ball along the horizontal surface with sufficient force to travel through the curvilinear surface and up the vertical surface. The force of gravity then causes the ball to return back down the vertical surface and—if appropriately aimed and struck—the ball travels downwardly into the opening of the least one ball receiving cup. Players are awarded points for successfully landing the ball into the ball receiving cup and the game may include differently sized and/or positioned cups having different point values.

Abstract:
A method and apparatus for disinfecting the interior of pipelines and conduits, particularly water mains. Ozone is utilized as the disinfectant vehicle to neutralize microbial contamination of the conduit. An ozone generation system includes a venturi injector for introducing ozone into pressurized water to provide a treating solution that is introduced into and that flows along a predetermined length of the conduit to be treated. The ozone concentration is regulated to maintain an ozone residual at the conduit outlet of about 0.2 mg/L to about 0.3 mg/L for a time sufficient to assure the desired level of disinfection of the conduit interior. Carbon dioxide can be added to improve the ozone residual stability and the effectiveness of disinfection. The apparatus is transportable and can be carried by a transportation vehicle, such as a truck or trailer, for on-site disinfection of pipelines at varying sites.
Abstract:
An in-home water treatment system that provides three stages of treatment for incoming water. The first treatment stage is a particulate removal stage, utilizing a spun fiber filter pad. The second treatment stage is a chemical compound removal stage, utilizing a carbon block filter. The third treatment stage is a disinfection stage utilizing an ultraviolet lamp. The three treatment stages are contained within a tubular enclosure to provide stage-by-stage treatment of the incoming water to improve its quality.
Abstract:
A disinfection reactor for disinfecting liquid, such as water from a water filtration plant, by exposing the liquid to ultraviolet light. The reactor includes a generally rectangular reactor vessel and two or more medium pressure ultraviolet lamps that extend within the reactor vessel in a direction transverse to the direction of liquid flow therethrough. The reactor vessel includes liquid guide surfaces that guide liquid to flow in a converging flow path having a reduced-area flow region in the vicinity of the ultraviolet lamps. The ultraviolet lamps are positioned spaced from and between the guide surfaces.
