An ultraviolet purification system in which ultraviolet 73 Assignees: Christian Sauska; George Csokneyai, radiation is generated by an ultraviolet lamp wherein both of Orange, Conn. the amount of ultraviolet radiation is varied in accor (21) Appl. No.: 469,203 dance with fluid flow. The intensity of the ultraviolet frt or y lamp is controlled by a circuit which is responsive to 22 Filed: Jan. 24, 1990 fluid flow for selectivity energizing the lamp to provide 51) Int. Cl. .
