Abstract
A method of removing noxious odors and preventing erosion within waste water headworks, said headworks including a headworks structure for waste water, an inlet line, an outlet line and a vent line; a method of removing noxious odors and preventing erosion within said headworks structure, comprising the step of introducing into a vapor space above the level of said waste water in said headworks structure, a low turbulence flow of ozonated air in sufficient volume of said ozonated air to form a blanket above said level of said waste water in said headworks structure and in an ozone concentration effective to prevent the formation of a biofilm, said introduction of ozonated air further being of a sufficient volume and ozone concentration to substantially react with malodorous gases present in said headworks structure without causing substantial erosion of said headworks structure by said ozonated air.
