A high intensity, high temperature UV Lamp reactor system for treating aqueous media on a continuous flow basis is provided. The reactor system comprises: a cylindrical reactor vessel, having inlets and outlets which permit the aqueous media to flow on a continuous basis through the reactor, a cylindrical UV lamp provided in the vessel and concentric therewith, a cylindrical UV transparent sheath for isolating the UV lamp from the interior space of the reactor vessel, the sheath and lamp being concentric with the cylindrical vessel, the sheath being sealed to the ends of the vessel to isolate the UV lamp from the aqueous media flowing through the annular reactor chamber, a brush device is provided for brushing the exterior surface of the sheath to remove therefrom materials deposited from the aqueous media, the brush having at least two brushes with bristles extending radially inwardly towards the sheath as the brushes encompass the sheath, the brushes are coupled together in spaced apart manner on the sheath with a device for reciprocating the brushes along the sheath exterior, preferably on a periodic basis to remove any deposited material from the sheath and thereby maintain an acceptable level of UV radiation transmitted into the annular chamber of the reactor. |

DETAILED DESCRIPTION According to an aspect of the invention, an apparatus for removing material deposited on a protective sheath enclosing a UV lamp where the material is deposited on the sheath from an aqueous solution passing over the sheath and through which the solution is exposed to UV radiation from the UV lamp.
The apparatus comprises: a) a brush having a bristle holder adapted for surrounding the sheath, the bristle holder having a plurality of bristles extending inwardly from the bristle holder, b) the brush being dimensioned such that the bristles along the brush holder surrounding the sheath are flexed at least when the brush is moved along the sheath to remove material deposited on the sheath, c) the bristles being individually in point contact with the sheath as tips of the bristles contact the sheath, and d) means for connecting the brush to an external drive for reciprocating the brush along the sheath, the connecting means being adapted to accommodate lateral movement of the brush as the brush moves along the sheath.
In a reactor according to another aspect of the invention which has at least one UV radiation lamp for treating an aqueous solution, the lamp being positioned in the reactor within a protective UV radiation transparent sheath, the lamp being isolated from the aqueous solution by the sheath, means for removing material deposited on the sheath from an aqueous solution being treated in the reactor, the improvement in the means for removing material deposited on the sheath comprising: a) a brush having a bristle holder adapted for surrounding the sheath, the bristle holder having a plurality of bristles extending inwardly from the bristle holder, b) the brush being dimensioned such that the bristles along the brush holder surrounding the sheath are flexed at least when the brush is moved along the sheath to remove material deposited on the sheath, c) the bristles being individually in point contact with the sheath as tips of the bristles contact the sheath, and d) means for connecting the brush to an external drive for reciprocating the brush along the sheath, the connecting means being adapted to accommodate lateral movement of the brush as the brush moves along the sheath
