The objective of this study is to present an integrated stochastic approach for quantifying the risk of oil spill in marine waters and adjacent coasts. This was achieved via the effective cooperation between the National Technical University of Athens (NTUA) and the Bogazici University (BU) within...

The Zlatibor mountain massif has significantly changed for the past 20 years due to the development of tourism, which has resulted in an increase in water consumption and environmental threats. This area abounds in considerable surface and groundwater resources, which are not utilised adequately...

Cu 2 O photocatalyst is synthesized by solvothermal method. Morphology and structure of Cu 2 O photocatalyst are analyzed by SEM, XRD and N 2 sorption technique. The catalytic performances and reaction kinetics of Cu 2 O photocatalyst for the degradation of methylene blue (MB) are investigated. The...

It is well known that chlorine and its compounds, traditionally utilized for water and wastewater disinfection, react with some organic matter to form undesirable by-products, hazardous to human health, known as Disinfection By-Products (DBPs). In many countries very stringent limits for...

Hydrogen peroxide consumption is known to be one of the key parameters of the photo-Fenton process responsible for its high operating costs. The purpose of this study was to find out whether adding dissolved oxygen to the reaction medium in a continuous stream of pure oxygen or air with different H...

The construction of large infrastructure projects such as highways, railroads, landfills, airports, harbours offers great social-economic opportunities for the development of a region; it is also mainly responsible for the deterioration of natural environment in the greater areas where these...

This study examines the implication of a market-based system to allocate water regionally in one of the most intensively irrigated areas of Greece. The proposed approach combines elements from administrative allocation and tradable water rights in order to assess several water supply scenarios under...

This study investigates the effect of different pre-treatments on the bio-ethanol production from the soluble compounds of the organic fraction of the municipal solid wastes (OFMSW). The experimental evaluation was performed on leachate samples obtained after mixing OFMSW with water during 10 d. The...

Recently, the fate of emerging compounds in environmentally relevant samples has attracted considerable attention. Solar semiconductor photocatalysis may offer an appealing methodology to treat such contaminants. At the same time the use of solar photocatalysis for water and wastewater disinfection...

In this work, three samples of nitrogen-doped TiO 2 prepared at different calcination temperatures (400, 450 and 500 °C) were applied for the adsorption of Direct Black 38. Kinetic studies about the adsorption of Direct Black 38 on nitrogen-doped TiO 2 were performed under different initial dye...
