Wastewater disinfection applying solar energy
(Corresponding) ZKERI E., Vourdoubas I., Katsivela E.
Topic:
Wastewater treatment
Solar Water Disinfection Process (SODIS) is a simple technology using solar UV-A radiation (wavelength 320-400 nm) and elevated water temperature to inactivate pathogens. In the present survey, the effect of solar radiation on the disinfection of domestic secondary treated wastewater from the...Read more

Site selection of hybrid solar/wind renewable energy systems: A case study from Andros, Greece
Bili A., (Corresponding) Vagiona D.
Topic:
Spatial environmental planning
The combination of two or more forms of Renewable Energy Sources at the same spatial scale is a highly promising sector, resulting in an increase in the number of installations of hybrid RES systems. In Greece, where abundant resources such as wind and sun are available, the combination of these...Read more

Topic:
Spatial environmental planning
Climate change and its environmental effects have raised the need to use mild forms of energy. Solar photovoltaic panels and wind turbines are by far the biggest drivers of the rapid increase in renewable energy electricity generation. There are several technologies of photovoltaic systems such as...Read more
TiO2/Fe2O3 based Composites for Solar-driven Photocatalytic Degradation of Amoxicillin
(Corresponding) dela Rosa F., Papac J., Kovačić M., (Corresponding) Kušić H., Božic A.
Topic:
Advanced oxidation processes
The occurrence of trace amounts of antibiotics in various bodies of water was directly linked to the development of antibiotic resistant pathogens. Recently, Amoxicillin (AMX) was added on the second EU “watch list” based on the proposed European Decision 2018/840/EU. Its presence in drinking water...Read more

Silver decorated TiO2/g-C3N4 nanocomposites for photocatalytic elimination of water pollutants under UV and artificial solar light
Ibrahim I., Belessiotis G., Kaltzoglou A., Katsaros F., Salama T., (Corresponding) Falaras P.
Topic:
Water treatment
TiO2/g-C3N4/Ag nanocomposites were prepared and used as highly efficient photocatalysts. TiO2 nanoparticles were first prepared using a sol-gel process, and titania herostructures with varying amounts of graphitic carbon nitride (g-C3N4) were created using a hydrothermal technique. Following...Read more

Applying solar distillation for the sustainable management of olive mill wastewater
Mastoras P., Gatidou G., Vakalis S., Fountoulakis M., Haralampopoulos D., (Corresponding) Stasinakis A.
Topic:
Wastewater treatment
Olive mill wastewater (OMWW) is a major by-product of olive oil production industry. Its chemical characteristics (high concentrations of COD and TSS, low pH value, existence of total phenols at the range of some ppm) does not allow its efficient treatment using conventional physiochemical or...Read more

Determining the phenological stages of Nestos-Delta (Alnus glutinosa) riparian forest (Natura 2000 site) by using radiation transmittance data
(Corresponding) Proutsos N., Karetsos G., Tsagari C.
Topic:
Environmental data analysis and modelling
Trees’ phenology is a key factor for most forests’ physiological processes. The precise definition of the start-end dates and the duration of each phenological stage is critical. In the present study, radiation data were used from pyranometers installed at the Alnus glutinosa riparian forest of...Read more

Technological solutions for giving a new life to power plants of alternative energy: social, economic, and environmental assessment of end of life scenarios
(Corresponding) Ambrosino C., Giaquinto D., Maselli G., Nesticò A., Zarra T., Belgiorno V., Naddeo V.
Topic:
Energy technologies and sustainability
The resources on the planet are not unlimited and special attention has been paid to alternative energies in recent years.
Alternative (or renewable) energy are all those energy sources that do not come from fossil fuels (coal, oil and natural gas). To date, wind and solar energy are the main...Read more

Influence of common solar and climate cycles on groundwater level variations
(Corresponding) Chapanov Y., Bournaski E.
Topic:
Estimation and prediction under past and future conditions (climate, population, land use change)
The groundwater is one of the most important natural resources. It provides drinking water and water for businesses. The level of groundwater varies in time. It has significantly seasonal oscillations and long-term variations, induced by rainfalls and climatic droughts. The seasonal, interannual...Read more

Variations of mean daily discharge of Danube river at 16 stations
(Corresponding) Chapanov Y., Bournaski E.
Topic:
River systems in diverse climates and environments
The river discharge is the main source of freshwater for large surface areas. Its deep minima are connected with drought events, while its maxima – with floods. The time series of river discharge consist of significant seasonal variations, modulated by long-term oscillations. The seasonal,...Read more
