A general methodology for photoreactor analysis and design based on the fundamentals of chemical reaction engineering and radiative transfer in participating media is presented. Three applications in the field of advanced ...

A modified dose concept for microorganism inactivation employing almost monochromatic, low wavelength radiation has been studied using disinfection data obtained with Escherichia coli bacteria and germicidal UV lamps. This ...

Most of the research work on photoreactor analysis, modeling, and design published so far relies on two approaches to represent the emission of tubular radiation sources:  the line (linear) source models (LSMs) and the ...

A kinetic model describing Fenton and photo-Fenton degradation of paracetamol (PCT) and consumption of hydrogen peroxide (H 2 O 2 ) was proposed. A set of Fenton and photo-Fenton experiments (18 runs in total) was performed ...

The radiation field in photocatalytic packed beds results from direct energy exchange between the lamp and the catalytic beads, and from mutual exchange between beads that are close to each other. The statistical description ...

The performance of photocatalytic reactors is largely conditioned by their configuration. In particular, photocatalytic wall reactors are affected by configuration-linked factors such as diffusive resistances, reactor ...

A general procedure to perform the scaling-up of photochemical reactors from first principles is presented, working with three applications to Advanced Oxidation Technologies. This work is not a review paper on the subject; ...

The photochemical efficiency of a fluidized bed (FB) of quartz sand coated with TiO2 by plasma-CVD, was investigated using a fully illuminated, parallel planar photoreactor. The local volumetric rate of photon absorption ...

A model of a bench-scale, annular, continuous flow reactor for the photocatalytic disinfection of water, operated under conditions of no perfect mixing is presented. The performance of the photoreactor has been simulated ...
