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.
An apparatus for use in a liquid treatment process, the apparatus comprising:
The apparatus according to any preceding claim, comprising a plurality of rotary elements axially separated in the vessel or conduit.
The apparatus according to any preceding claim, comprising a plurality of rotary devices distributed circumferentially in the annular flow volume defined by the conduit or vessel.
The apparatus according to any preceding claim, wherein the rotary device is configured to generate a thrust on a liquid in the liquid treatment vessel.
The apparatus according to any preceding claim, wherein the rotary device comprises one or more sacrificial components which wears, degrades or otherwise deteriorates as a consequence of cavitation induced by the rotary device.
The apparatus according to any preceding claim, wherein one or more components of the apparatus comprises aluminium.
The apparatus according to any preceding claim, wherein one or more components of the apparatus is partially or fully coated with a photocatalytic material.
The apparatus according to any preceding claim, wherein one or more components of the apparatus is partially of fully constructed from a photocatalytic material.
The apparatus according to any preceding claim, wherein in use, the rotary device is arranged to be disposed a distance less than 10mm from a radiation-emitting surface of the source of ultraviolet radiation.
The apparatus according to any preceding claim, comprising a support structure for the rotary device.
A method of treating a liquid in an advanced oxidation process reaction, the method comprising:
