In advanced oxidation processes (AOPs) operating in continuous mode, the flow rate and concentration of oxidants such as H2O2 at mixing point influent must be controlled so that oxidant residuals effluent are minimized while organic degradation is maximized. Designing a controller to regulate therefore, its photoreactor influent, needs determination reliable process dynamic model. this study, s...

The use of microflow reactors enabled dramatic improvements in the apparent rates photochemical reactions. However, scaling-up photomicroreactors remains a challenge due to difficulties distributing light and flow all units photomicroreactors. In this work, mass photon transfer limitations an easily scalable micro-structured reactor, aerosol photoreactor, was studied. reactor concept, each drop...

Photocatalytic degradation of pesticides with titanium dioxide (TiO(2)) and other catalysts has shown promise as a potential water remediation method. Titanium-based powders have been used in photocatalytic degradation studies but have limitations. The objective of this study was to determine picloram degradation in water using various UV light sources and low-pressure metal organic chemical va...

Residence time distribution (RTD) study of solids in a three-phase pilot-scale bubble column photoreactor has been carried out in order to provide data for the development of an artificial neural network model usable for process optimisation. The experimental data indicated that the RTD of solids was a complex nonlinear function of gas and liquid velocities as well as the contacting pattern (co...
