New membrane reactor configurations for wastewater treatment

The candidate will participate in a research project that deals with the coupling of membrane technology and advanced oxidation processes. The main objective of the project is to develop and test new family of carbon-based (or like) membrane reactors for the treatment of wastewater containing emergent or recalcitrant organic contaminants, using hydrogen peroxide, ozone or photocatalytic methods. The technologies to be developed are based on the integration of reaction and separation steps through selective ceramic membranes (of nano- or ultrafiltration) used as support for a deposited carbonaceous layer possessing catalytic activity or the deposition of conductive polymers to facilitate the transfer of the electrons in such redox reactions. Catalytic membrane reactors represent a relatively new class of water treatment technologies, combining filtration of colloidal particles with catalytic oxidation of recalcitrant water contaminants. This approach demonstrates copious benefits in comparison with conventional separated membrane filtration and catalytic oxidation systems. In addition to obvious footprint and capital costs reduction, it allows combining the backwash cycle prerequisite for maintenance of membrane flux with the restoration of catalyst activity. Although different approaches to creation of ceramic membranes with inherent catalytic activity have been proposed, one critical drawback of all these approaches requires to be retreated. Surprisingly, this negative property is the same that typically makes ceramic membranes so effective. Virtually all ceramic, i.e. oxide, nitride and carbide-based materials, are well-known to be extremely hydrophilic. Although this intrinsic property of ceramic materials is obviously on target for filtration purposes, superhydrophilicity becomes a problem when membranes are expected to work as catalytic surfaces. In one approach, the carbon membrane synthesis methodology will be developed in order to obtain a thin carbon layer over the ceramic filtration elements. Starting from a polymeric precursor, the layer will be created by controlled carbonization and the main variables affecting the process will be optimized to get defect-free carbon layers. Later, the surface will be modified to impart suitable catalytic properties to the surface. In a different path, turbostratic carbon nitride films will be obtained by simply pyrolising polymeric precursors and optimized for electrochemical treatments taken profit of its inherent stability and conductive properties.
