The project combines different methodologies: phyco-purification with microalgae, developed by the PARLab Group of the Interdepartmental Center for Studies Levi Cases at the University of Padua; the use of zeolites and nanosponges, developed by TEA Sistemi in collaboration with the Department of Chemistry at the University of Turin; electrochemically activated solutions, tested by AMAG Reti Idriche in collaboration with the DISIT Department of the University of Eastern Piedmont (UPO) – Alessandria. In addition, the project aims to improve sludge quality through processes for the removal of emerging pollutants such as hydrocarbons, pharmaceuticals and agrochemicals, heavy metals, and biological agents such as antibiotic resistance genes.
