Abstract

An irradiator apparatus has a plurality of gamma radiation sources mounted in a housing and includes an ozone generator located in the housing and using the irradiator gamma radiation sources to generate the ozone. A plurality of gamma radiation sources are mounted in the irradiator housing with a gas passageway formed around each source for irradiating air or oxygen passing therearound from a gas input through the housing. A fluid passageway is located inside the irradiator housing and adjacent the plurality of gamma radiation sources for irradiating a liquid passing therethrough. The fluid passageway is connected between a liquid input opening and a liquid output opening through the irradiator housing. The gas passageways connect the ozone generator tubes to the fluid passageway for feeding ozone into the liquid being irradiated so that the irradiator generates ozone and feeds the ozone into the fluid being irradiated. The irradiator gamma radiation sources are used for generating the ozone in the ozone generator as well as irradiating the fluid passing through the irradiator.
