Long term solids handling alternatives for New York City water resource recovery facilities (WRRFs)
(Corresponding) Ramalingam K., (Corresponding) Fillos J., Katehis D.
Topic:
Energy technologies and sustainability
New York City Department of Environmental Protection, DEP, owns and operates 14 waste water treatment plants which treat a combined average dry weather flow of 57 m3/sec. (1.3 billion gallons per day). The plants have been upgraded periodically to address more stringent discharge permit limits with...Read more
Thermal degradation of perfluorooctanoic acid (PFOA)
(Corresponding) Stockenhuber S., Weber N., Dixon L., Lucas J., Grimison C., Bennett M., Stockenhuber M., Mackie J., Kennedy E.
Topic:
Soil and groundwater contamination and remediation
Per - and polyfluoroalkyl substances (PFAS) are a group of environmental contaminants, that are dispersed throughout the world. A number of areas have been affected by their persistence and biomagnification. PFAS remediation of contaminated material requires extensive knowledge of the species...Read more

Effect of chain length on the pyrolysis of perfluorocarboxylic acids
(Corresponding) Dixon L., Stockenhuber S., Weber N., Lucas J., Grimison C., Stockenhuber M., Mackie J., (Corresponding) Kennedy E.
Topic:
Emerging pollutants
Per- and polyfluoroalkyl substance (PFAS) are increasingly becoming the contamination issue of our time, due to their environmental persistence, bioaccumulation and mounting evidence of their toxicity. Herein we examined the pyrolytic decomposition of a series of perfluorocarboxylic acids via the...Read more
Thermal Decomposition of Chlorpyrifos - an Experimental Investigation
(Corresponding) Weber N., Stockenhuber S., Dixon L., Lucas J., Grimison C., Stockenhuber M., Mackie J., Kennedy E., Benhelal E.
Topic:
Soil and groundwater contamination and remediation
Organophosphate compounds are a group of chemicals that are commonly used in pest control. One widely used organophosphate is chlorpyrifos (CPF), which has been associated with acetylcholinesterase inhibition (AChE), an acute neurotoxin. Further, under thermal decomposition conditions, such as...Read more
Testing and validation of ENVI-met simulations based on in-situ micrometeorological measurements: the case of Syntagma square, Athens, Greece
Koletsis I., Tseliou A., Lykoudis S., (Corresponding) Pantavou K., Tsiros I.
Topic:
Enviornmental data analysis and modelling
The present paper focuses on the development of a methodology that simulates micrometeorological thermal conditions in an urban context based on weather station data. The micrometeorological conditions at Syntagma square, the central square of Athens, Greece were simulated by ENVI-met software in...Read more

The integration of three field survey datasets in Athens, Greece: transformation of five-point to seven-point thermal sensation scale
(Corresponding) Pantavou K., Lykoudis S., Delibasis K., Tseliou A., Koletsis I., Nikolopoulou M., Tsiros I.
Topic:
Enviornmental data analysis and modelling
The integration of the datasets from three different field surveys on thermal sensation conducted at eight different sites of the area of Athens, Greece was examined. All three surveys were carried out with similar methodologies so data integration can be considered meaningful. The surveys included...Read more

Indoor and outdoor environment impact over the generic conditions for thermal bridge appearance
(Corresponding) Ivanov M., Mijorski S.
Topic:
Enviornmental data analysis and modelling
The presented study considers the numerical modelling of a thermal bridge distribution, based on conjugated heat transfer and Computational Fluid Dynamics (CFD) model of approximated external concrete wall. The thermal bridge distribution is cross-analyzed relative to the indoor and outdoor air...Read more

Thermal bridge modelling, based on conjugated heat transfer and CFD methods
Mijorski S., (Corresponding) Ivanov M.
Topic:
Enviornmental data analysis and modelling
In the building structure, the “thermal bridge” is defined as an isolated zone, where construction elements have higher thermal conductivity, compared with the rest of the building envelope. Thus, a significant temperature difference may exist between adjacent solid and air volumes within the...Read more

Thermal swing adsorption for post-combustion carbon dioxide capture
(Corresponding) Boycheva S., Zgureva D., Miteva S., Marinov I., Lazarova H., Popova M.
Topic:
Climate change mitigation and adaptation
The advantages of post-combustion capture of CO2 based on physical adsorption have been extensively studied in the last years regarding to the economy, environmental compatibility, and process’ efficiency. The industrialization of the process involves the construction of adsorption columns in which...Read more

THE FATE OF MICROPLASTICS DURING THE ANAEROBIC DIGESTION OF THERMALLY PRETREATED SLUDGE
(Corresponding) Cesaro A., Pirozzi F., Zafirakou A., Alexandraki A.
Topic:
Microplastics in water treatment: fate, toxicity assessment and removal technologies
The presence of microplastics (MPs) in the water environment has raised as an issue of great concern, mainly due to their persistence and potential adverse effects on biota. Municipal wastewater treatment plants have been claimed among the most important point source of MPs. Nevertheless, they act...Read more
