Abstract
An apparatus and a method for killing bacteria within an opaque liquid. The opaque liquid is moved along a high power ultraviolet radiation surface at a velocity which causes turbulent flow in the liquid. The turbulent flow mixes the opaque liquid so that all the liquid is exposed to the radiation even though the radiation does not penetrate the liquid to any significant depth. One embodiment of the invention moves the liquid in a serpentine path between multiple planar lamps which radiate UV from both planar surfaces.
