Abstract
An ultraviolet sterilization and disinfection system for fluids which includes apparatus for sensing selected operating characteristics such as physical characteristics of the fluid to be disinfected or sterilized and the operating conditions of the ultraviolet sources proportioning these variable and generally non-linear parameters and modifying such factors as fluid flow, ultraviolet energy imparted to the fluid to insure destruction of selected organisms without the use of excessive energy. Control may also be provided for the admission of selected quantities of disinfecting chemicals such as chlorine to the fluid.
Claims10
Apparatus for destroying undesirable organisms in a fluid comprising at least one ultraviolet radiation source, a fluid chamber having an inlet and outlet at least partially surrounding said source for guiding said fluid into close proximity to said source to effect penetration of said fluid by said radiation, means at said inlet for measuring physical characteristics of said fluid including flow rate, means for sensing the radiation intensity of said source imparted to said fluid and the radiation intensity emerging from said fluid to determine the radiant energy absorbed by said fluid and means for regulating the relationship between fluid flow and radiation intensity of said source to impart a selected quantity of radiant energy to said fluid per unit volume thereof, said selected quantity being determined by the measured characteristics of the fluid.
Apparatus for destroying undesirable organisms in a fluid comprising at least one ultraviolet radiation source, a fluid chamber having an inlet and outlet at least partially surrounding said source for guiding said fluid into close proximity to said source to effect penetration of said fluid by said radiation, means for measuring physical characteristics of said fluid including flow rate and turbidity, means for sensing at least the radiation intensity imparted to said fluid, means for measuring the radiation intensity emerging from said fluid, means for determining the radiant energy absorbed by said fluid, and means for regulating the relationship between fluid flow and radiation absorbed by said first to impart a selected quantity of radiant energy to said fluid per unit volume thereof, said selected quantity being determined by the measured characteristics of said fluid.
