(9) With reference to FIG. 1, there is illustrated a fluid treatment system 10 comprising an open channel 15. Open channel 15 comprises a floor 20 and a pair of sidewalls 25. For clarity, only one of sidewalls 25 is shown in FIG. 1. Disposed in open channel 10 is a pair of radiation source modules 100, which will be described in more detail with reference to FIGS. 2-7. As illustrated, in use, fluid (e.g., water) flows in the direction of arrow A (those of skill in the art will understand that it is also possible to have fluid (e.g., water) flowing in the reverse direction of arrow A).

(10) As can be seen in FIG. 1, the upstream radiation source module 100 is shown with the frame elements thereof retracted from the in use position. This allows for servicing of the radiation source elements in radiation source module 100. As further illustrated in FIG. 1, the downstream radiation source module 100 is shown in an in use position.

(11) With reference to FIGS. 2-4, there is illustrated radiation source module 100. Radiation source comprises a pair of frame elements 105. Each frame element 105 comprises a pair of side frame elements 107,109 interconnected by a top frame element 111 and a bottom frame element 113. Disposed in each frame element 105 is a plurality of elongate radiation source elements 115. Each radiation source element 115 comprises an elongate radiation source such as an ultraviolet radiation source.

(12) A first drive element 117 is secured to a side portion of frame element 105 adjacent to side frame element 107. A second drive element 119 is secured to a side portion of frame element 105 adjacent to side frame element 109. As set out above, these drive elements may be hydraulic, pneumatic or mechanical in their design.

(13) With reference to FIGS. 5-7, additional detail is provided on the interaction of drive elements 117, 119 and frame element 105 (for clarity, the focus will be on drive element 119).

(14) FIG. 6 represents an enlarged portion of circle B in FIG. 5 while FIG. 7 illustrates an enlarged portion of circle C in FIG. 5.

(15) As illustrated, a first coupling plate 121 is secured to each bottom frame element 113 of each frame element 105. Coupling plate 121 is also secured to drive element 119. A second coupling plate 123 is secured to top frame element 111 of frame element 105.

(16) Drive element 119 is configured to be actuated in a direction of arrow D shown in FIGS. 6-7. When this occurs, the pair of frame elements 105 in radiation source module 100 is retracted as shown in the upstream radiation source module in FIG. 1. Once retracted, the radiation source element in frame element 105 may be serviced and thereafter returned to an in use position by reversibly actuating drive elements 117, 119.

(17) With reference to FIG. 8, there is illustrated a modified embodiment of the radiation source module illustrated in FIGS. 1-7.

(18) FIG. 8 illustrates a radiation source module 200 comprising a total of six (6) frames 205. Each frame 205 is of a similar design and construction of frame 105 in radiation source module 100 illustrated in FIGS. 1-7. The principal difference between radiation source module 100 illustrated in FIGS. 1-7 and radiation source module illustrated in FIG. 8 is that the six (6) frames in the latter are retracted with a single pair of drive elements (only drive element 219 is illustrated in FIG. 8 for clarity but it will be understood that a second drive element 217 would be disposed on the opposite side of radiation source module 200).

(19) As shown drive element 219 is disposed between the middle pair of frame elements 205. The two outer pairs of frame elements 205 are secured to the middle pair of frame elements 205 by any suitable means (e.g., additional coupling plates, etc.). In the result, when the pair of drive elements in radiation source module is actuated, all six (6) frame elements 205 are retracted.

Thus, various modifications of the illustrative embodiments, as well as other embodiments of the invention, will be apparent to persons skilled in the art upon reference to this description. For example, while the motive element of motive elements shown in the illustrated embodiments include a pneumatic, hydraulic, or mechanical device (such as winch), it is possible to modify these embodiments so that the module extraction device is human powered. It is therefore contemplated that the appended claims will cover any such modifications or embodiments.
