La présence de composés pharmaceutiques dans notre environnement est nocive pour la faune et la flore aquatiques ainsi que pour l'Homme. Elle doit donc être empêchée. Cependant, les systèmes de traitement d'épuration des eaux ne sont toujours pas suffisamment efficaces pour dégrader entièrement ces molécules. C'est pourquoi le projet "Traitement Oxydatif de ComposEs Pharmaceutiques, TOCEP" a été créé: il consiste à l'élaboration d'un traitement de finition des eaux en sortie de stations d'épuration à partir d'un traitement oxydatif avancé, soit une combinaison d'ozonation et de photocatalyse hétérogène. Ce travail de fin d'études s'inscrit dans la lignée de ce projet et plus particulièrement dans la participation à la mise au point du photocatalyseur idéal, principalement à base de dioxyde de titane, pour la dégradation de composés pharmaceutiques en phase aqueuse. L'influence de différents paramètres opératoires sur l'efficacité de dégradation de ces composés pharmaceutiques est également étudiée. The presence of pharmaceutical compounds in our environment is harmful for the aquatic fauna and flora as well as to humans. Therefore, it has to be prevented. However, wastewater treatment systems are still not efficient enough to fully degrade these molecules. The "Oxidative Treatment of Pharmaceutical Compounds, TOCEP" project was created in this context. It consists of the development of a finishing treatment of wastewater at the outlet of sewage treatment plants by an advanced oxidative treatment, meaning a combination of ozonation and heterogeneous photocatalysis steps. This master's thesis is in the continuity of the project and more particularly in the participation in the development of the ideal photocatalyst, mainly based on titanium dioxide, for the degradation of pharmaceutical compounds in aqueous phase. The influence of different operating parameters on the degradation efficiency of these pharmaceutical compounds is also studied.

With the increasing global usage of water and the continuous addition of contaminants to water sources, new challenges have arisen that are associated with the abatement of organic pollutants, particularly those that are refractory to conventional water and wastewater treatment technologies. Advanced oxidation processes (AOPs) present a competitive alternative to promote the oxidation of organic contaminants by strong oxidative radicals generated from oxygen, ozone, wet peroxide, and UV radiation. The use of catalysts not only improves efficiency but may present remarkable cost advantages for practical applications of AOPs in the abatement of several pollutants. In this Special Issue of Catalysts, we invite authors to submit original research papers focused on the synthesis and characterization of novel heterogeneous catalysts and their uses in advanced oxidation processes for the removal of organic pollutants from aqueous solutions.

This book, titled “Nanofiltration Membranes: Recent Advances and Environmental Applications”, aims to assess the recent developments and advances in all the aspects related to nanofiltration (NF) technology and its environmental applications. This book has ten articles, including eight research articles and two reviews. Various topics are discussed, including fabrication of organic and inorganic NF membranes, tailoring NF membranes’ surface properties, the application of NF in side-stream valorization, using NF technology in combination with other membrane technologies such as ultrafiltration (UF) and reverse osmosis (RO), wide-range applications of NF for removing organic and inorganic pollutants and viruses, and a detailed sustainability assessment of the use of NF technology via life cycle assessment (LCA).

Catalysts are widely used in a great variety of technologies, providing remarkable efficiency in order to address sustainable energy production, climate change challenges, and to reduce industrial emissions. In the framework of the Environmental Catalysis section promoted by the Catalysts Editorial Office, this Special Issue, entitled “Environmental Friendly Catalysts for Energy and Pollution Control Applications”, comprises novel studies representing the state-of-the-art research for efficient energy generation and industrial emission control based on new environmentally friendly catalyst materials (EFCs). In particular, in this Special Issue (SI), different kinds of catalysts are presented for catalytic solutions, including the reduction of NOx emissions (new zeolite catalyst modified with Pt), the elimination of volatile organic compounds (Co3O4@SiO2 and acidic surface transformed natural zeolite) and the removal of SO2 emissions (through adsorption processes with sodium citrate). Moreover, novel biocatalysts for bioanodes and new functional nanostructured catalysts based on metal–organic framework (MOFs) for different applications are also included. Additionally, articles compiled in this SI are also focused on the improvement of catalytic processes. Thus, selected processes based on activated carbons (modified with titanium dioxide) and optimized Fenton processes for the removal of aqueous organic pollutants or for the inactivation of bacteria are also presented.
