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

Degradation of textile dyes in water by gas-liquid NSP-DBD plasma

MEROPOULIS S., (Corresponding) AGGELOPOULOS C.

Topic:

Advanced oxidation processes

Textile dyes represent some of the most complicated environmental pollutants due to their variety and complex structure. Cold atmospheric plasma (CAP) is regarded as a highly competitive advanced oxidation process towards the removal of organic pollutants from wastewater. In this study, a gas-...Read more

Application of carbon-based catalysts derived from compost on catalytic wet peroxide oxidation of leachate waters from mechanical and biological treatment plant units for municipal solid waste

Batista G., (Corresponding) Roman F., Diaz de Tuesta J., Mambrini R., Gomes H.

Topic:

Advanced oxidation processes

This work aims at the valorization of compost from mechanical and biological treatment (MBT) units of municipal solid waste by their transformation into carbon-based catalysts for further application in the treatment of MBT leachate waters (chemical oxygen demand (COD) = 60.0 g L-1, total organic...Read more

Aloe Vera waste for Methylene Blue (MB), Rhodamine B (RB) and Methyl Orange (MO) adsorption.

(Corresponding) Mazzeo L., Bavasso I., Di Palma L.

Topic:

Wastewater treatment

Aloe Vera (Aloe barbadensis miller) waste obtained from a local cosmetic production factory was used as bio-adsorbent for the removal of three different dyes: Methylene Blue (MB), Rhodamine B (RB) and Methyl Orange (MO). The material was preliminary washed with water at room temperature. Batch...Read more

Integration of negatively charged MWCNT-fGO self-assembled nanomaterials into PLA polymeric membranes for wastewater treatment

(Corresponding) Khalil H., Nassar L., Wadi V., Naddeo V., Banat F., (Corresponding) Hasan S.

Topic:

Wastewater treatment

The integration of nanomaterials in membrane’s matrix aims to improve the membrane’s hydrophilicity, mechanical strength, thermal stability and water flux, which are vital membrane properties needed to active efficient removal of contaminants. Multi-walled carbon nanotubes (MWCNT) and...Read more

Synthesis of self-assembled graphene oxide (GO)/manganese oxide (MnO2) sulfonated-polyethersulfone (SPES) membranes for heavy metal removal from wastewater

Ibrahim Y., Wadi V., Ouda M., Naddeo V., Banat F., (Corresponding) Hasan S.

Topic:

Wastewater treatment

As the 21st century continues, water scarcity remains a significant burden to overcome in many regions. The treatment of industrial wastewater has great potential in providing adequate quantities of freshwater. To ensure safe usage of this water, heavy metal ions must be removed to avoid their...Read more

Use of a two-stage MBBR system for medium-strength dairy wastewater treatment

Katsara A., Iliopoulou A., Zkeri E., Aloupi M., Fountoulakis M., (Corresponding) Stasinakis A.

Topic:

Wastewater treatment

A two-stage Moving Bed Biofilm Reactor (MBBR) system consisting of a methanogenic and an aerobic reactor in series was used for medium strength dairy wastewater treatment. An energy analysis was conducted for the methanogenic MBBR to investigate its autonomy and its potential to act as a...Read more

Catalytic reduction of Cr(VI) using recovered Silicon from end-of-life photovoltaic panels as a catalyst

Pavlopoulos C., Kyriakopoulou V., (Corresponding) Papadopoulou K., Lyberatos G.

Topic:

Wastewater treatment

As installed photovoltaic panels (PVP) approach their end of life, the need for a sustainable recovery plan becomes imperative. This work aims to reuse Silicon from End-of-Life PVP as a potential catalyst/photocatalyst for wastewater treatment. PVPs were pretreated thermally (550°C for 30 min). The...Read more
