Abstract
An apparatus for use in a liquid treatment process, and a method of use is described. The apparatus comprises an inlet configured to be connected to a source of liquid to be treated and an outlet for discharging liquid from the apparatus. At least one liquid treatment vessel or conduit is disposed between the inlet and the outlet, and is arranged to expose liquid in the vessel to ultraviolet radiation in an advanced oxidation process reaction. A source of ultraviolet radiation extending along the liquid treatment vessel or conduit, such that an annular flow volume is defined in the vessel or conduit around the source of ultraviolet radiation. A rotary device is disposed in the annular flow volume and a drive mechanism drives rotation of the rotary device. The rotary device is operable to induce cavitation in a liquid present in the annular flow volume.
