Electrochemical Treatment of Landfill Leachate under Cold Climate Conditions

(Corresponding) Ambauen N., Meyn T., Hallé C., Muff J.

Topic:

Advanced oxidation processes

This study shows that electrochemical oxidation of landfill leachate (LL) is significantly affected by cold temperatures prevailing in Nordic climate areas. As hypothesized, the degradation of common wastewater parameters (TOC, COD) exhibited lower efficiency when low average temperature (13°C) was...Read more

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

The Effect of Different Parameters on Electrochemical Removal of Ampicillin Using New Generation Sn/Sb/Ni-Ti Anodes

(Corresponding) Kurt A., (Corresponding) Yonar T., Shakir F., Helvacıoğlu H., Neşelen E.

Topic:

Advanced oxidation processes

In this study, it was aimed to investigate the feasibility of new generation and stable Sn/Sb/Ni-Ti anodes for treatment of wastewater containing Ampicillin (AMP) antibiotic by electrochemical oxidation processes. Ampicillin concentration was 0.05 g L-1 in the aqueous solution. Residual ampicillin...Read more

Degradation of Cylindrospermopsin using Advanced Non-Thermal Plasma Technologies

(Corresponding) Schneider M., Rataj R., Kolb J., Bláha L.

Topic:

Advanced oxidation processes

The application of non-thermal plasmas in wastewater and air purification received a lot of attention, but their potential application in drinking water treatment has scarcely been investigated. Classified as Advanced Oxidation Processes, plasmas ignited in water or at the air-water interface...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 pillared clays for the removal of pollutants from wastewater by treatment with oxidation processes

(Corresponding) Kalmakhanova M., Massalimova B., Diaz de Tuesta J., Gomes H.

Topic:

Advanced oxidation processes

The constant development of technological processes aggravates the problem of pollution, due to a significant change in the composition of effluents that makes necessary the development of new (and/or improvement of the existing) treatment methods and catalytic materials. In this sense, the use of...Read more
