"Environmental assessments of municipal wastewater systems"
Water resources management and the wastewater sector, in particular, faces multiple challenges in relation to its sustainability. This lecture addresses few of these challenges in a systematic way, especially focusing on emerging topics and our research contributions.
This presentation disscusses the development and implementation of three environmental assessment methods to evaluate the performance of municipal wastewater systems and to identify and quantify the local impacts of wastewater discharges: life cycle assessment, an environmental impact assessment index and the water footprint.

“Post-closure influence of emissions resulted from municipal waste deposits: a case study of the North-East region of Romania”
The goal of this study was to evaluate the level of pollution considering 5 closed municipal waste deposits from North-East region of Romania over the period 2013-2015, considering the possibility of methane emissions valorization from biogas. The results showed that the impact on environmental quality was very high for 2 counties, due to pollution migration from North to South, and from one environmental component to another (from soil to ground water). The overall impact was quantified by two conventional assessment methods.

“Advanced oxidation processes for removal of priority organic pollutants from wastewater”
Advanced oxidation processes are recognized as highly efficient in removing organic pollutants from wastewater. Pillared clays heterogeneous catalysts present very good catalytic activity and stability against iron leaching. This study considered the characterisation of newly synthesized materials by Mössbauer and DR-UV–vis spectroscopies that suggested the presence of two iron species: low-nuclearity ferric oxides and well-ordered hematite-like nanoparticles. Catalytic tests with 4-chlorophenol in aqueous conditions were performed, the dependence of the removal efficiencies on the operational parameters being also studied.
