Topic:
Sustainable water management in the mediterranean – technological solutions, demonstration and deployment
This paper offers a concise overview of the main strengths, weaknesses, opportunities and threats, as derived from the institutional, policy and regulatory framework governing wastewater treatment and reuse in three Mediterranean countries. The SWOT analysis is based on a desk review of available...Read more

Investigation of variables affecting UV-LED photocatalytic degradation of antibiotics ciprofloxacin and sulfamethoxazole
(Corresponding) Bertagna Silva D., Buttiglieri G., Babić S.
Topic:
Advanced oxidation processes
In this study, photolytic and photocatalytic degradation of two antibiotics in ultra-pure water were analyzed. A lab-scale cylindrical reactor had its inner walls impregnated with TiO2 nanofilm for the photocatalytic experiments. In the first step, an optimized photoreactor design was chosen based...Read more
Prior electro-mechanical separation to improve metal recovery from ceramic-rich electronic waste using bioleaching
(Corresponding) Baniasadi M., Ray D., Graves J., Bolton R., Renshaw D., (Corresponding) Farnaud S.
Topic:
Solid waste management
PCBs, as one of the most valuable streams of e-waste, are a considerable source of precious metals, but also contain considerable amounts of plastic and ceramic. These non-metallic fractions interfere with and can inhibit the efficiency of metal recovery, particularly for precious and rare earth...Read more
BRIEF BIOLOGY OF Sudanonautes africanus (CRUSTACEA: BRACHYURA: EUBRACHYURA: POTAMOIDEA: PATAMONAUTIDAE: POTAMONAUTINAE), IN OSSIOMO RIVER, NIGER-DELTA, NIGERIA
(Corresponding) Anani O., John O.
Topic:
Biodibersity conservation
The crab species africanus is a very notable detritivore, feeding on dead organic materials. It makes use of energy from the food and transfers it into the food chain trophic level, contributing to the gross ecosystem efficiency. However, their threat to human consumption and activities is...Read more
Planar Mixing Tool for Enhanced Performance of Covered Anaerobic Pond Systems
(Corresponding) Brück F., Velten H., Pingsmann M., Meyer D., Weigand H., Linnenberg C., Theilen U.
Topic:
New solutions for a better and sustainable agriculture
Pond systems are the simplest and most widespread technology for the treatment of high-strength wastewater containing biodegradable suspended solids. When covered, they offer significant advantages such as odour control, intensification of the decomposition process, and the potential to capture...Read more
CO abatement via Ir-based catalysts: effect of the support and preparation method on catalytic activity and stability
Drosou C., Fountouli T., Stratakis A., Charisiou N., Goula M., (Corresponding) Yentekakis I.
Topic:
Air pollution
Here we report on the effect of the support and preparation method on the activity and stability of Ir-based catalysts under CO oxidation. Alunina-ceria-zirconia (ACZ: 60wt%Al2O3 - 40wt%CexZr1-xO2, x=0.25, 0.5, 0.75) mixed oxide supports with high oxygen storage capacity (OSC) were synthesized via...Read more
EVALUATION OF PHOTOCHEMICAL DEGRADATION OF ANTIVIRAL ACYCLOVIR BY UVC/PS & UVC/H2O2 IN SYNTHETIC FRESH AND HYDROLYZED URINE
Drosou C., Tyrovola K., (Corresponding) Xekoukoulotakis N.
Topic:
Advanced oxidation processes
The increasing presence of contaminants of anthropogenic origin in the aquatic environment raises the concern of the scientific community (Patel et al., 2019). Antiviral drugs play an important role, as their presence in aquatic bodies is associated with antiviral resistance and chronic toxicity to...Read more
Sampling Strategies of Microplastic in Stormwater Runoff from Separate Drainage Systems
(Corresponding) Abusafia A., Scheid C., Meurer M., Altmann K., Braun U., Bannick C., Dittmer U., Steinmetz H.
Topic:
Emerging pollutants
The occurrence of microplastic in terrestrial and water environments can be traced back to anthropogenic activities. Urban drainage systems play a role in transporting microplastic from urban sources into receiving waters or soils. The analysis (including sampling, sample preparation and detection...Read more

Biodiesel Properties from Chlorella sorokiniana Bio-Oil Cultivated Heterotrophically with Industrial By-Products
Kokkalis A., Kasiteropoulou D., Papadopoulou A., Metsoviti M., Mpesios A., Gougoulias N., Spiliotis X., (Corresponding) Papapolymerou G.
Topic:
Environmental biotechnology and bioenergy
The fatty acid (FA) distribution of bio-oil derived from Chlorella sorokiniana and the biodiesel basic properties were examined. C. sorokiniana was cultivated heterotrophically in two growth media: a) glycerol and inorganic salts (GLIN) and b) glycerol and anaerobic digestrate (GLAD). The...Read more

AliCy as Extractant to Remove Iron from Copper-Free Extreme AMD for Further Extraction of Zinc
Nobahar A., Melka A., Neves L., Carlier J., (Corresponding) Costa M.
Topic:
Wastewater treatment
A previous work showed that copper can be specifically extracted from acid mine drainage (AMD) classified as high-acid and extreme-metals (pH 1.19, ~63 g/L Fe, ~6.5 g/L Al, ~5.3 g/L Cu, ~1.9 g/L Zn and ~0.1 g/L Mn), using 30% (v/v) Acorga M5640 in Shell GTL (a kerosene like solvent) as extractant...Read more
