Abstract

Water reuse has emerged as an important alternative to solve water scarcity problems. Biologically treated effluents contain a high amount of dissolved organic matter, which consists of a heterogeneous mixture of organic compounds that may also contain emerging contaminants. Consequently, to ensure adequate water quality for reuse, it is of paramount importance to develop new forms of treatment that are efficient, since conventional wastewater treatment cannot promote the removal of emerging contaminants. In this context, seeking a contribution to solve this problem, the present project proposes to apply several Multi-Barrier methods (MB) for polish effluents. The proposed multi-barrier methods consist of two-stages Advanced Oxidative Processes (AOPs) with biofiltration by Biological Activated Carbon (BAC). The first AOP will serve as a pre-treatment for biofiltration and the second AOP will serve as a post-biofiltration finishing step to ensure disinfection and removal of microcontaminants, being: alachlor, atrazine, carbofuran, metolachlor and molinate. The combination of AOPs in MB systems produces promising results, however little is known about the effective role of AOPs in these systems. In this sense, this project aims to investigate the role of AOPs, with emphasis on ozone and UV/H2O2 based processes and their combinations in MB coupled systems. The four MB configurations studied to verify the role of POAs in each step will be: (i) O3-BAC-O3; (ii) O3/H2O2-BAC-O3/H2O2; (iii) UV/H2O2-BAC-UV/H2O2; (iv) [O3/ H2O2 or O3]-BAC-UV/H2O2/UF. (AU)
