Abstract

In this work, the use of previously reported figures-of-merit is proposed for the comparison of solar-driven photocatalytic disinfection technologies using NF-codoped TiO2. These figures-of-merit are based on the solar collection area per order (ACO) through the understanding of the overall kinetic behavior of the disinfection process under the tested conditions: pH 7, four different catalyst concentrations (0.0, 0.10, 0.25 and 50 mgmL 1) and two solar radiation types (UV+visible and visible radiation alone). The results provide a direct link to the accumulated energy efficiency (the lowest the value the highest the efficiency) of the inactivation process, allowing the comparison between the efficiencies of a broad range of processes evaluating different experimental conditions.

Keywords: photocatalytic disinfection; doped titanium dioxide; scaling-up parameters; advanced oxidation technologies
