ABSTRACT:
A process for treating a fluid which comprises the step of exposing the fluid to ultraviolet radiation and high-energy ionizing radiation. It has been discovered that combining ultraviolet radiation with high-energy ionizing radiation in the treatment of a fluid results in synergistic performances of the treatment process—e.g., improvement in the inactivation or killing of microorganisms in the fluid, in destruction of organic contaminants and the like. More specifically, fluid treatment performance is improved to a level typically not possible when using ultraviolet radiation and high-energy ionizing radiation separately.
