3.2. Potential of thermally-enhanced SoDis
In order to assess the possibility of thermally enhanced SoDis, temperature variations in the test facility were
assessed. The manufactured system was placed under the array of lights. The Pyrex reactor tube was filled with
approximately 1.25 liters of water at approximately 20oC. Temperature sensors were located at each end of the
reactor tube. The system was orientated horizontally so as to avoid buoyancy-driven mixing within the tube.
Figure 2 shows the water temperature results. The results indicate that a batch of water would need to be exposed
to solar radiation for over 40 minutes before the water reached the critical temperature required for the enhanced
thermal SoDis effect. As the aim of the current work is to develop a continuous feed system, it is evident that
enhanced thermal SoDis cannot be assumed to work.
