Zusammenfassung:Apparatus and processes for non-chemical disinfection of a wide variety of biologically contaminated water streams include a canister with flow control means built therein such that a small portion of a water stream is exposed to disinfecting salts and returned to the principal stream to be treated. An ionized oxidizing gas plasma is also added, together with streams of metallic ions. Improved compositions of sacrificial electrodes for providing disinfectant metallic ions to a flow stream are also disclosed. The invention is described in connection with disinfecting recirculated water as used in cooling tower recirculated water air conditioning plants, commercial laundries, and aircraft head flush water, among other industrial water reclamation uses.
