Treatment of various agro-industrial wastewaters using electrocoagulation
Benekos A., Papadopoulos K., Triantaphyllidou I., Tekerlekopoulou A., (Corresponding) Vayenas D.
Topic:
Wastewater treatment
Greece, although not over-industrialized, is facing issues connected to pollution of its water resources, as conventional wastewater treatment methods often prove ineffective in terms of removing some pollutantssuch as suspended solids and pigments. Therefore, the need of developing efficient,...Read more
Exceptional flood events in the summer of 2018 in Trebes Negel Reprezentativ bazin (Romania)
(Corresponding) Paveluc L., Grozavu A., Cojoc G., Hutanu E.
Topic:
Floods, droughts and water scarcity
In the summer of 2018, the general unstable weather throughout the central and eastern parts of Romania has led to significant rainfall, sometimes exceeding 60 mm/day, and consequently to a massive runoff on the slopes that rapidly increased the flow on tributaries and the main course of the river...Read more
Managing the risk of cyanobacteria through water quality characteristics analysis: A case study of two warm Mediterranean reservoirs
(Corresponding) Antoniou M., Kagalou I., Hadjiouraniou G., Daskalakis E., Tsiarta N., Chamoglou M., Polykarpou P.
Topic:
Lakes, rivers, estuaries and ecosystem health
This study correlated the trophic condition of two Mediterranean water bodies with different typology with their water quality characteristics. The two studied cases included Polemidia Dam, a reservoir enriched with tertiary treated wastewater in Cyprus and Lake Karla, a re-established reservoir in...Read more

THE ENVIRONMENTAL IMPACT OF TOURISM AND THEIR EFFECT ON THE CULTURAL HERITAGE
FRAGKOU D., SINOU M.
Topic:
Environmental impacts of tourism and sustainable tourism development
The natural and cultural heritage, peculiar and living cultures are great tourist attraction. The intensive and inefficient management of tourism and the association with this development can damage the nature, integrity and the dominant characteristics of these. In this way the ecological...Read more

Sustainable purification of greywater with green walls
(Corresponding) Boano F., Caruso A., Costamagna E., Fiore S., Demichelis F., Ridolfi L., Galvão A., Pisoeiro J., Rizzo A., Masi F.
Topic:
Water and wastewater reuse
In this study, we describe a sustainable system for treatment and reuse of grey wastewater in urban areas through vertical green walls constructed on unused surfaces of buildings. The system integrates the benefits linked to the introduction of green spaces in urban areas with the advantages...Read more

RECOVERY AND SEPARATION OF VALUABLE METALS (COPPER AND ZINC) FROM ACIDIC MINE WATERS BY ION-EXCHANGE RESINS
(Corresponding) Vecino X., Reig M., López J., Valderrama C., Gibert O., Cortina J.
Topic:
Water and wastewater reuse
Mining wastewaters, containing heavy metals such as copper (Cu) and zinc (Zn), have a huge impact on the environment due to they are not biodegradable and tend to bioaccumulate in plants or living organisms. Therefore, in this work the performance of ion-exchange and solvent-impregnated resins were...Read more

Recovery of sulphuric acid and valuable metals (Zn, Cu and REE) from acidic mine waters using nanofiltration
(Corresponding) López J., Reig M., Vecino X., Valderrama C., Gibert O., Cortina J.
Topic:
Water and wastewater reuse
Acidic mine waters (AMWs) contains moderate concentrations of sulphuric acid, relatively high concentrations of metals (Al, Fe, Cu and Zn) and minor amounts or rare earth elements (REE). The established management routes for AMW treatment include a neutralization-precipitation step, which implies a...Read more
Environmental genotoxicity and risk assessment in herring (Clupea harengus), Atlantic cod (Gadus morhua) and flounder (Platichthys flesus) caught in the Gotland Basins from the Baltic Sea (2010-2017)
(Corresponding) Pažusienė J., Valskienė R., Stankevičiūtė M., Butrimavičienė L., Baršienė J.
Topic:
Biomonitoring
The Gotland Basins are mostly polluted by anthracene, benz(a)anthracene, benzo(k)fluoranthene, cesium-137, DDE, dioxins, mercury and TBT. These chemicals have toxic, carcinogenic and immunotoxic effect to marine animals. After the World War II chemical weapons (CW) were transported from Germany and...Read more

Valorisation of waste polyethylene by blending with ethylene-vinyl acetate and incorporation of a new type of compatibilizer
(Corresponding) Simon-Stőger L., Varga C.
Topic:
Solid waste management
Nowadays polyethylene is one of the polymers produced in the greatest volume, therefore, parallelly the amount of generated waste polyethylene (w-HDPE) significant as well. Valorisation and recycling of w-HDPE can be realized by blending with different types of polymers and/or elastomers in order...Read more
Innovative sensors for crowdsourced river measurements collection
(Corresponding) Krommyda M., (Corresponding) Tsiakos V., Rigos A., Tsertou A., Amditis A., Georgiou H., Jonoski A., Popescu I., Assumpção T.
Topic:
Process understanding through innovative sensors and remote sensing
Flood risk prediction requires consistent and accurate sensor measurements, usually provided from traditional in-situ environmental monitoring systems. Crowd-sourced data can complement these official data sources, allowing authorities to improve and fill gaps in the hazard assessment process...Read more
