Developing a new advanced treatment technique for MPs removal from water and wastewater
The presence of emerging micropollutants (MPs) in surface water, groundwater and sediments is currently of major concern, which will lead to the establishment of more stringent standards for the quality of surface water and industrial wastewater, especially in the European Union countries. MPs cannot be completely removed by biological treatment methods. With regard to the possibilities of removing trace organics from waste and drinking water, the performance of various technologies, mostly conventional (adsorption, membrane and oxidation processes), have already been investigated. According to these studies, processes such as ozonation and adsorption on powdered activated carbon (PAC) are seen as promising treatment techniques for wastewater containing MPs. For several years, the laboratory Interfaces, Confinement, Matériaux et Nanostructures (ICMN) in Centre Val de Loire, France, has been active in the development of an advanced oxidative process, in particular O3/Granular Activated Carbon (GAC) combined system, for the elimination of phthalates and pharmaceutical compounds. It is necessary now to develop a new advanced oxidative process by coupling several processes for the mineralization of refractory emergent organic MPs.
