Abstract

A point of use water purification system for home use is provided comprising a carbon block filter housed in a self-contained disposable pressure vessel for removing particulates and organic contaminants from water. The filter is provided with a pore-size distribution, a binder and a flow path which optimizes filtration performance and enhances microbiological kill rates obtained in a source of radiant energy which is used to kill microorganisms in the filtered water. The source of radiant energy comprises an ultraviolet discharge lamp having an elongate central axis and a diverter for providing a spiral plug flow of water about the discharge lamp. A flow regulator adjusts flow through the system for varying line pressure conditions to ensure adequate exposure of microorganisms to ultraviolet energy. A lamp control circuit conserves power and optimizes ultraviolet output. A
diagnostic system includes a filter monitor which provides an automatic indication to the user when the filter has reached its end of life. The diagnostic system includes a radiation source monitor which provides an automatic indication to the user when the UV discharge bulb has malfunctioned. A filter quick-disconnect, a radiation source quick-disconnect and associated power safety interlocks protect the user and facilitate the safe and easy replacement of the disposable filter cartridge and ultraviolet discharge bulb.
