Techno-economic analysis of solar detoxification systems

Solar detoxification technology has shown great promise for treatment of toxic compounds in the ground water and wastewater However, detailed analysis of the impact of techno-economic parameters on the treatment cost for the detoxification process is lacking in the literature. In this paper, the impact of different process parameters on the treatment cost has been presented and various strategies for reducing the cost of treatment have been discussed. For the processes with the reaction rate constants less than 0.1 min(-1), the system economics is very sensitive to the reaction rare constant and the unit reactor cost. However, for the reaction rate constant over 0.1 min(-1) the general treatment costs can be reduced mainly by reducing the unit catalyst costs.
