Abstract
The invention provides a water treatment apparatus and method of use. The apparatus comprises an inlet configured to be connected to a source of liquid to be treated, and at least one liquid treatment vessel arranged to expose liquid in the vessel to ultraviolet radiation in an advanced oxidation process reaction. A source of ultraviolet radiation comprises a longitudinal axis oriented substantially parallel to a direction of flow of liquid past the source. A boundary surface between the source and a liquid to be treated is provided with one or more cleaning elements arranged longitudinally on the boundary surface. The cleaning elements and the boundary surface are arranged to be rotationally moveable relative to one another around the longitudinal axis of the source.
