A system, method and apparatus for determining and controlling water clarity or water opacity especially useful in pools, spas, and contained bodies of water.

System and apparatus for determining and controlling water clarity

Each cap of a pair of end caps mounted on opposed ends of a conventional radial flow cylindrical filter element of a filter cartridge includes a circular sleeve extending axially from the filter element for penetrably receiving a supporting stud and for maintaining an O-ring seal therebetween. The area of one of the end caps radially outwardly of its circular sleeve is greater than the corresponding area of the other end cap to cause fluid to be filtered to pressure bias the filter cartridge toward the other end cap and to positionally retain the filter cartridge within its housing. A positioning member extending into the filter element from one of the end caps receives and stabilizes sleeve for a u/v lamp disposed within the filter element to kill any microorganisms present and to oxidize any organic matter subjected to the emitted ultra-violent radiation.

A time delay in de-energizing the electronic ballast and its associated UV lamp subsequent to cessation of water discharge from a user-activated water treatment unit ensures irradiation of the water prior to a subsequent user-activated water discharge and reduces the likelihood of any live microorganisms being present in the water subsequently discharged. A soft start of the UV lamp upon actuation of the water treatment unit reduces the mechanical stresses imposed upon the filaments of the UV lamp and the life span of the UV lamp is enhanced.

The supply of water used in dental operations and other applications in a dental office, or other medical facility, wherein non-contaminated water is necessary to avoid transmission of microorganisms, is enriched with oxygen, whether from ambient air or a source of oxygen. The oxygenated water is passed through a silver containing catalyst cartridge. The water borne oxygen is attracted to the silver and forms a weak bond sufficient to permit dissociation to oxidize organic matter, including microorganisms. A small amount of silver dissolves in the water and flows downstream through the attendant conduits to and through dental handpieces and dental implements. A portion of the silver will adhere to the walls of the conduits, handpieces and implements where it is free to react with the oxygen dissolved in the water flowing therepast. The resulting oxidizing of the organic matter will destroy any biofilm present and prevent biofilm buildup. To enhance oxidizing of the organic matter, an ozone generator may be employed to introduce ozone into the water upstream of the silver catalyst cartridge.

Catalytic dental water apparatus

An ozone generator injects and entrains ozone enriched air into water to be used by a dentist or technician during a dental procedure. The ozone entrained in the water will eliminate the motility and viability of any microbes and pathogens present in the water or in biofilm present in the water lines or channels conveying water to a patient's oral cavity. The ozone generator may be used in combination with water from a municipal water source or from bottled water. Alternatively, the ozone generator may be incorporated within a bottle supplying distilled or otherwise puritied water.
