ABSTRACT:
A system and method is disclosed for purifying water for drinking or bathing purposes employing an optical scanning device for detecting organisms in the water such as bacteria, algae, or viruses. The optical scanning device may be a video camera or may comprise a laser for irradiating the organisms and a photodetector for detecting radiation emanating from the organisms. A computer analyzes scanning signals generated by the scanning device and controls a device for neutralizing the organisms, such as a chemical injector or radiation source, in accordance with the scanning signals. The system may also be used to detect and neutralize disease producing organisms in a body fluid of a patient or in any fluid used for biological experimentation, testing, or production.
