ABSTRACT:
Disinfection of aqueous media contaminated with microorganisms is effected by contacting said media with a gas phase in which a plasma is generated by focused laser radiation. Similarly, wastewaters containing organic susbstances are purified by contacting them with an oxygen-containing gas phase in which a plasma is generated by focused laser radiation which promotes oxidation of the organic substances to innocuous products.
