A system for disinfecting water streams comprises a source of ionized plasma, that is, a stream of air including ionized oxygen and nitrogen gas atoms and molecules, ozone, and singlet molecular oxygen, and an additional source of metal ions. The gas plasma is introduced into the water stream upstream of the metal ion stream to produce a variety of oxidizing, coagulating, and disinfecting reactions. Further, the metal ions combine with the gas ions to form additionally known disinfectant compounds. The source of ionized gas molecules is an ultraviolet lamp driven at very high frequency by a pulsated signal and optionally juxtaposed to a coil providing electric and/or magnetic fields, to excite and ionize oxygen and nitrogen molecules of the air. The metal ions are provided by sacrificial electrodes comprising alloy members of the metal elements to be provided to the water stream. A DC potential applied to the electrodes is uniformly reversed at intervals, to encourage sacrificial erosion thereof. The system may be provided as a retrofit disinfectant, coagulation, and purification plant for swimming pools or like closed loop domestic or industrial water systems, or used for non-chemical treatment of drinking water and/or non-chemical purification treatment for environmental water purification and safe discharge applications, replacing chlorination and other conventional chemical coagulation treatments.

A method for removing pollutants, impurities, organics, and other undesirable components from a water stream, comprising the steps of: defining a stream of atmospheric air; passing said stream of atmospheric air through an exposure zone including a source of ultraviolet radiation including components between 160-185 and 250-265 nm wavelength, said air stream in said exposure zone passing through the interior of conductive coil means connected to power supply means for emitting one or both of electric and magnetic fields, whereby a stream of air including a substantial fraction of ionized gas molecules is generated; introducing said stream of air including ionized gas molecules to said water stream; providing a stream of ions of elements which, when chemically combined with the ions of said stream of ionized gas molecules, form compounds having one or more of bactericidal, viricidal, algicidal and fungicidal disinfection properties; mixing said water stream, having had said stream of air including ionized gas molecules introduced thereinto, with said stream of ions of elements, under conditions such that one or more of said compounds are formed in situ, and such that one or more of bacteria, viruses, algae, and fungi in said water stream are killed; and filtering said water stream after said mixing step, to remove said killed bacteria, viruses, algae, and fungi therefrom.
