Removal of emerging contaminants from water by a hybrid membrane-catalytic oxidation process
Bourassi, Mahdi ; Klusoň, Petr (advisor) ; Bendová, Magdalena (referee) ; Granger, Pascal (referee)
Emerging contaminants were detected in different surface waters around the globe. These active molecules affect the environment even at trace concentrations. They are sourced mainly from wastewater treatment plants. These contaminants persist the conventional wastewater treatments and gain their way to the environment. This can cause different complications: bioaccumulation, antibiotic resistance, and environmental degradation. The presented Ph.D. thesis is focused on the treatment of wastewater loaded with persistent pollutants. This thesis aimed to evaluate the membrane separation technology and the catalytic wet air oxidation (CWAO) process to associate them in a hybrid process to address this issue. The first part of the hybrid process is focused on challenges faced with the membrane separation process, mainly fouling and selectivity. This part gathers 6 publications all focused on wastewater treatment with membrane separation. As a starter, the review covers the issue presented by the emerging contaminants and the potential of the membrane process for water recovery. The review highlighted the advantages and challenges (fouling and selectivity) of the membrane process. The chapter about membrane fouling gathers two publications: "Removal of ibuprofen from water by different types of...

How can we best eliminate pharmaceuticals from wastewater?
Bourassi, Mahdi
Persistent pharmaceutical occurrence in different lakes and rivers usually originates from live stocks, agriculture, aquaculture, households, and hospitals. The presence of these compounds in the ecosystems leads to fatal consequences. Pharmaceuticals can threaten microorganisms in the environment, either causing its deterioration or allowing pathogens to gain resistance against antibiotics and medical treatments. These occurrences in the environment questions the ability of conventional treatment to remediate pharmaceutical wastewater.
