“…4) so that almost the entire circumference of the receiver tube is illuminated. The CPCs fulfill the main i-vi criteria stated above [8]. The CPCs have the advantages of both technologies (PTCs and non-concentrating collectors) and none of their disadvantages so they seem to be the best option for photocatalytic processes based on the use of solar radiation [2].…”

For the last four decades, viability of photocatalytic degradation of organic compounds in water streams has been demonstrated. Different configurations for solar TiO 2 photocatalytic reactors have been used, however pilot and demonstration plants are still countable. Degradation efficiency reported as a function of treatment time does not answer the question: which of these reactor configurations is the most suitable for photocatalytic process and optimum for scale-up and commercialization? Degradation efficiency expressed as a function of the reactor throughput and ease of catalyst removal from treated effluent are used for comparing performance of different reactor configurations to select the optimum for scale-up. Comparison included parabolic trough, flat plate, double skin sheet, shallow ponds, shallow tanks, thin-film fixed-bed, thin film cascade, step, compound parabolic concentrators, fountain, slurry bubble column, pebble bed and packed bed reactors. Degradation efficiency as a function of system throughput is a powerful indicator for comparing the performance of photocatalytic reactors of different types and geometries, at different development scales. Shallow ponds, shallow tanks and fountain reactors have the potential of meeting all the process requirements and a relatively high throughput are suitable for developing into continuous industrial-scale treatment units given that an efficient immobilized or supported photocatalyst is used.

“…The area of the single compound parabolic trough reactor was 0.0946 m 2 and the total area of the reactor was 0.3784 m 2 . Hence it could receive almost 88% UV radiation incident on it (Blanco et al, 1999). The designed compound parabolic trough reactor with four channels is shown in Fig.…”

“…Most of the solar photocatalytic reactors use only UV part of the solar irradiation for waste water treatment. The dependency of reaction rate on solar irradiation has led the researchers to use the concentrator based reactors for photocatalytic applications (Blanco et al, 1999;Duran et al, 2010;Jing et al, 2009;Klausner et al, 1994). Among the different concentrating type photocatalytic reactors the solar compound parabolic trough reactor is the most studied one because of its efficient light harvesting (Klausner et al, 1994).…”
