A wetted wall ultraviolet photoreactor for the disinfection of liquids

Abstract
Constructional details are given of an ultraviolet photoreactor designed specifically to disinfect liquids, particularly wastewaters, of high turbidity. The liquid to be disinfected flows vertically as a turbulent film concentrically to a tubular ultraviolet source. A particular advantage of this type of photoreactor is that the liquid does not foul the ultraviolet source as contact between the two does not occur. Preliminary results for the disinfection of a wastewater at different flowrates through the photoreactor are presented.
