Abstract The Society of Water and Sanitation Supply of Campinas (SANASA - Campinas-SP-Brazil) has a Reuse Water Production Plant (EPAR CAPIVARI II), where a Bioreactor with Ultrafiltration Membranes (MBR) system is applied for domestic sewage treatment and water production for non-potable use. At EPAR CAPIVARI II there is a pilot plant composed of several processes, such as ozonation, UV radiation, peroxidation, photoperoxidation, reverse osmosis, activated carbon, and disinfection, which allows the performance of tests for polishing effluents from the MBR system. This research proposal is part of an agreement between the National Institute of Advanced Analytical Sciences and Technologies (INCTAA) and SANASA. Many of the compounds of emerging concern present in the EPAR CAPIVARI II influent are only partially removed/degraded by the MBR system. The main goal of this Postdoctoral project is to evaluate the application and combination of the different advanced treatment processes for the improvement of the water quality. Firstly, the degradation/removal studies of the recalcitrant compounds will be carried out on a laboratory scale to obtain some parameters. The best processes combination will be evaluated at the pilot scale using real eflluent. The process's efficiency will be assessed according to the removal level of the target compounds using online solid-phase extraction and ultra-high performance liquid chromatography associated with sequential mass spectrometry (SPE-UHPLC-MS / MS). Also, (eco)toxicity and antimicrobial activity of the solutions during the application of the processes will be performed. The microalgae Raphidocelis subcapitata, the bioluminescent marine bacterium Vibrio fischeri, and the microcrustacean Daphnia similis will be used as test organisms. The bacteria Escherichia coli and Bacillus subtilis will be used in antimicrobial activity tests. (AU) | |
