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.
