Changes of dissolved oxygen during the caffeine oxidation by photo-Fenton
Villota N., (Corresponding) Lomas J., (Corresponding) Irene C.
Topic:
Advanced oxidation processes
The aim of this work is to analyse the changes of dissolved oxygen ([DO], mg/L) during the oxidation of caffeine waters by photo-Fenton treatment. The concentration of dosed hydrogen peroxide would be the addition of the stoichiometric [H2O2], which reacts with organic matter ([H2O2]esteq=2.0 mM),...Read more
Employing data-driven models in the optimization of chemical usage in water treatment plants
(Corresponding) Kandris K., Romas E., Tzimas A., Gavalakis E.
Topic:
Enviornmental data analysis and modelling
One of the most challenging tasks in potable water production is the cost-efficient and consistent operation of water treatment plants (WTPs) that treat raw water of variable quality and quantity. To increase process stability and optimize the usage of resources, two data-driven models simulated...Read more

Enhanced of TiO2-Ag photocatalysis performance for removal of methylene blue in presence of acetone
(Corresponding) HARJA M., DUDUMAN NUTESCU C., APOSTOLESCU G., GÓMEZ DE SALAZAR J., GÓMEZ DE CASTRO C., SESCU A., FAVIER L., CIOBANU G.
Topic:
Nanomaterials in the environmnents applications and effects
In the present study, the photocatalytic degradation of methylene blue (MB), using TiO2-Ag synthesized by sol-gel method, as a catalyst under UV light, was studied. The samples synthesized were characterized by SEM, EDAX, FTIR, XRD and TEM. The average size of the particles was 10 nm. Tests were...Read more
Aerobic degradation of tetramethyl ammonium hydroxide (TMAH) from effluents of semiconductor industries: kinetic studies of laboratory and pilot experiments
(Corresponding) Innocenzi V., De Michelis I., Ippolito N., Mazziotti Di Celso G., Prisciandaro M., Vegliò F.
Topic:
Wastewater treatment
Aerobic degradation of effluents contains tetramethylammonium hydroxide molecules (TMAH), coming from an electronic industry, were studied at laboratory and pilot scale. At the first, the preliminary experiments were conducted using a lab scale reactor inoculated with activated sludge coming from...Read more

Impact of traffic management strategies on air quality and health in a Portuguese urban area
(Corresponding) Silveira C., Ferreira J., Lopes D., Miranda A.
Topic:
Air pollution
This paper aims to assess the air quality improvement and resulting health implications in a Portuguese urban area, by testing traffic management scenarios focused on nitrogen dioxide (NO2) emission reduction. To that end, an integrated multiscale modelling system was developed and applied for a...Read more

An Agent Based Modelling tool exploring decision-making processes for flood risk management
(Corresponding) Koutiva I., Makropoulos C.
Topic:
Water policy, management and society
Cities at risk of extreme hydro-meteorological events need to be prepared to decrease the extent of the impacts. However, the majority usually reacts to the catastrophe, having failed to proactively prepare against extremes. This can be a result of both absent structural protection measures and...Read more

Spatial explicit evaluation of potential future developments of forests due to climatic change and nitrogen deposition
Dr. Jenssen M., Dr. Nickel S., (Corresponding) Dr. Schröder W.
Topic:
Enviornmental data analysis and modelling
Climate change and atmospheric nitrogen deposition can impact the integrity of ecosystems. Therefore, the EU Biodiversity Strategy foresees that Member States map and assess the state of ecosystems and their services in their national territory. By example of Germany, this article presents a...Read more

A system dynamics model to quantify the impacts of restoration measures on the water-energy-food nexus in the Urmia lake Basin, Iran
Bakhshianlamouki E., Masia S., Karimi P., van der Zaag P., (Corresponding) Susnik J.
Topic:
Water, energy and/or food nexus
Water scarcity exacerbated by growing demand has created environmental, social, and economic challenges in the Urmia Lake Basin (ULB), Iran. Tackling these requires an integrated approach. A System Dynamics Model is developed simulating the water-energy-food nexus in the ULB as a holistic multi-...Read more

Introducing UWAB 2.0. and exploring next steps for agent based modelling in domestic water demand.
(Corresponding) Koutiva I., Eftaxias K., Makropoulos C.
Topic:
Estimation and prediction under past and future conditions (climate, population, land use change)
Domestic water consumption projections are needed to manage the urban water supply system in different spatiotemporal resolutions depending on the type of the supported decision. For instance, operational decisions require predictions of fine resolution (hourly or lower), while tactical and...Read more
Numerical Modelling of Wave Reflection from Port Structures for Reliable Forecasting of Berth Downtime
(Corresponding) Chondros M., Malliouri D., Metallinos A., Papadimitriou A., Karambas T., Makris C., Baltikas V., Kontos Y., Nagkoulis N., Androulidakis Y., Klonaris G., Tsoukala V., Memos C.
Topic:
Marine environment and coastal management
Forecast of wave agitation inside port basins and consequent downtime of berth positions are of utmost importance to make a port “smarter” by efficiently managing its infrastructure. Within Accu-Waves project (http://accuwaves.eu), a decision-making tool is being developed to provide forecast data...Read more
