Wastewater treatment processes utilizing hydrodynamic cavitation

(Corresponding) Innocenzi V., Prisciandaro M., Vegliò F.

Topic:

Advanced oxidation processes

In the present work, the potentiality of the hydrodynamic cavitation (HC) for the degradation of organic pollutants from industrial effluents has been studied. Cavitation is a phenomenon of formation, growth, collapse of microbubbles or cavities, in a few milli- to microseconds and releases large...Read more

Fluoride-free Anodization of Titanium and the Photocatalytic Behaviour the Produced TiO2 Nanostructures

Taylor C., (Corresponding) Wenk J., Mattia D.

Topic:

Advanced oxidation processes

Current methods for anodizing titania to produce immobilized titanium dioxide (TiO2) photocatalyst require the use of hazardous fluoride electrolytes. A fluoride-free electrolyte anodization method was developed. The electrolytes tested in this study were both bromide- and chloride-based and...Read more

New evidence of accelerated elimination of an emergent water pollutant by TiO2 assisted photo-oxidation

(Corresponding) FAVIER L., LASLAU A., SIMION A., SESCU A., HARJA M., RUSU L.

Topic:

Advanced oxidation processes

Over the past few years, the presence of the pharmaceuticals and their metabolites in the aquatic environment has become an important public health issue. These molecules are generally released in the aquatic ecosystem through the effluents of conventional wastewater treatment plants which were not...Read more
