An apparatus 20 for use in a liquid treatment process, such as a water treatment process, comprises an inlet 24 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 25 is disposed between the inlet and the outlet, and the vessel or conduit is arranged to expose liquid in the vessel to ultraviolet radiation in an advanced oxidation process reaction. A source of ultraviolet radiation 26 extends 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 100 is disposed in the annular flow volume and a drive mechanism 106 drives rotation of the rotary device. The rotary device is operable to induce cavitation in a liquid present in the annular flow volume. One or more components of the apparatus can be coated with, or constructed from, a photocatalytic material. A method of treating a liquid in an advanced oxidation process reaction is also claimed. |
