Abstract
A split stream ultraviolet purification device, for the treatment of liquids that are normally opaque to ultraviolet radiation, is provided with means for adding a selected amount of clear water to the inlet stream of untreated liquid entering a ultraviolet purification chamber. The clear water dilutes the opaque untreated liquid sufficiently to assure that the ultraviolet radiation level transmitted to the liquid flowing through the purification chamber is of a dosage high enough to effect complete disinfection. A control system regulates the flow of clear water to maintain a preselected level of ultraviolet radiation in the purification chamber and the control system diverts the discharge of the purification chamber to the source of untreated liquid in the event that the level of ultraviolet radiation in the purification chamber falls below the preselected level.
