Abstract
Contaminants in an aqueous stream are oxidized with minimal use of an added oxidant by diffusing the oxidant through a fixed porous element followed by cyclical photolytic treatment of the stream with at least two different wavelengths of light. The porous element is preferably formed in one piece of a durable sintered ceramic material. The photolytic treatment preferably involves the sequential use of ultraviolet light having two different wavelengths, by which complementary oxidizing reactions occur within the stream being decontaminated.
Claims12
A system for decontaminating an aqueous fluid at ambient temperature, said system comprising:
- a housing;
- a rigid porous element fixedly contained within said housing, said porous element having an elongated interior channel;
- a first inlet for introducing an oxidant into said housing such that the oxidant diffuses into said porous element, and a second inlet for introducing an aqueous fluid into said elongated interior channel such that the oxidant is introduced into the aqueous fluid within said elongated interior channel;
- exposure means cyclically exposing the aqueous fluid within said elongated channel to ultraviolet light having at least two different wavelengths;
- and
- an outlet for withdrawing the aqueous fluid from said housing, said outlet being in fluid communication with said elongated interior channel of said rigid porous element.
