About the Multidisciplinary Seminar Program

Created in 1995, the Escola Tecnica Superior d'Enginyeria Quimica (ETSEQ) at Universitat Rovira i Virgili aims at becoming an international reference in chemical engineering education and research. The ETSEQ is located in an area that is socially and economically very dynamic, and that is home to one of the most important centers of chemical industry in southern Europe.

The Multidisciplinary Seminar Program is both the seminar series for faculty and researchers in the ETSEQ, and a mandatory class for its graduate students. The Program aims at inviting leading international researchers working on areas that are of interest to faculty and researchers in the School.

Doctoral defense: "Novel Anaerobic Packed-Bed Reactor Application for Wastewater Remediation" (Yonhara García)

Location: Sala de Graus, ETSEQ
Start time: 12 p.m.

Abstract:

Emergent pollutants are compounds with different origin and chemical nature, therefore they are difficult to be degrade in conventional wastewater treatment plants taking also into account their toxicity and difference in concentration. The utilization of biofilm reactors has proven to be an efficient process for the degradation of chemical compounds, due to a synergetic effect is produced between the biofilm and the support material which enhance the good capacities of both to retain and/or degrade these recalcitrant pollutants.Thus, the objective of this thesis has been the application of a novel anaerobic up-flow packed-bed reactor for the removal of some priority emergent pollutants.For this purpose anaerobic culture immobilized over activated carbon and/or carbonaceous material was utilized.Adsorption experiments of some studied pollutants were carried out over activated carbon, in order to delineate between how much is due to adsorption and how much to biotransformation. The results showed that with this novel system high degradation rates were obtained for each studied contaminants, between 0,14- 34,92 g L-1 d-1, at very short space times.On the other hand, preparation and surface chemistry modification of different carbon materials was studied in the thesis, taking into account the possibilities offered by these carbon materials to be modified and take benefit of their unique specific properties. Moreover, the complete mineralization of the azo dye Acid Orange 7 in an anaerobic-aerobic sequential system was investigated, obtaining a total removal efficiency of 80,28 % at total hydraulic residence time of approximately 49 h.
