World¿s population increase along with the expected economic development, are major challenges to water and energy consumption. Water treatment technologies upgrade is the key to facing current water quality challenges. The utmost challenge for drinking water and wastewater treatment, as well as water reuse, is linked to the presence of natural organic matter (NOM) and micropollutants in raw water, the latter often. The presence of pharmaceutical compounds (PhCs ) in the environment is a reality that calls for more efficient water treatment technologies. Processes initiated by light have been demonstrated in many cases to have a strong influence on the environmental fate of PhCs. Photodegradation at the top level of surface waters may be a natural elimination pathway for recalcitrant PhCs in environmental waters. The present work is being a deep insight into the Photodegradation process of anti-inflammatory drugs in wastewater.

Hydroprocessing is one of the key unit operations in today¿s oil refineries. Its importance will increase in the coming decades, due to more stringent fuel quality legislation and further growth of the global fuel demand. Moreover, nitrogen compounds, naturally occurring in crude oil, have been identi¿ed as strong inhibitors of the hydrodesulfurization (HDS) reactions during the hydrotreatment process. This project was divided into two phases: in phase one a parametric and kinetic study of HDS activity for an oil fraction loaded with thiophen, as a sulfiding model, onto a commercial CoMo/Al2O3 were investigated, and in phase two the effect of two different nitrogen compounds (e.g., carbazole and pyridine), which are commonly identified in fractions of crude oil, on the HDS activity and hydrodenitrogenation (HDN) activity was studied. A kinetic analysis of the operating system was also included in phase two.
