Abstract

This project deals with the study of the ozonation process coupled to ultra/biofiltration aiming at the removal of micropollutants in effluents. For this purpose, it is planned to optimize the ozonation process of micropollutants and to couple it to membrane biofiltration. The goal of combining ozonation and ultra/biofiltration is that ozone treatment of micropollutants can produce more toxic by-products than starting materials. Therefore, the addition of ultra/biofiltration is interesting to increase the purity of the water obtained at the end of the treatment. One of the main problems attached to ultra/biofiltration is the fouling of membranes that culminates in decreased efficiency in the pollutant removal process. The use of the polyacrylamide-based membrane would minimize fouling as well as its coating with graphene oxide and polyvinyl pyridinium iodide, which are bactericidal materials, also contributed to the fouling decrease. Thus, the aim of this project is to develop new antifouling membranes to complement the ozonation process in the removal of micropollutants in effluents. Thus, the optimization of the ozone degradation and ultra/biofiltration process will be studied to alkylphenols and organophosphorous compounds to verify its efficiency. Furthermore, it is planned to study the mechanisms involved in the ozonation and biofiltration through high performance liquid chromatography analyzes coupled with high resolution mass spectrometry.
