Efficiency of Arsenic Removal from Water Using Fe-Modified Biochar from Date-Palm-Leaves Combined with Spectral Induced Polarization (SIP) Monitoring
Siddiq O., (Corresponding) Tawabini B., Kirmizakis P., Kalderis D., Ntarlagiannis D., Soupios P.
Topic:
Water treatment
In this study, lab-scale column batch adsorption experiments were conducted to demonstrate the efficiency of Iron-modified Biochar (Fe-BC) produced from date-palm leaves at 500oC to remove arsenic (As) from contaminated water. The As removal capacity were monitored by both chemical analysis and...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
This study investigated the removal of arsenite (As(III)) and arsenate (As(V)) in aqueous solution using iron-coated pomelo peel (ICPP). Batch adsorption experiments were performed to evaluate the effects of initial pH values (2.0–10), contact time (1–1440 minutes), initial concentration (0.05–5 mg...Read more

Nutrient Removal from Stormwater using Australian Native Plants in Constructed Floating Wetland
(Corresponding) Nuruzzaman M., Anwar A., Sarukkalige R.
Topic:
Water treatment
Stormwater pollution causes excessive nutrient influx to rivers and lakes, which can trigger algal bloom and subsequent damages to the freshwater ecosystem. Constructed Floating Wetland (CFW), a cost-effective technology, uses aquatic plants in a hydroponic system to strip nutrients from stormwater...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
