The overall objective of the ÍTACA project was to investigate new technological concepts for the treatment of industrial and urban wastewater that enable, in an efficient and sustainable manner, the transformation of current treatment processes into a strategy focused on water reuse, recovery of substances, byproducts and waste, and energy valorisation, while minimizing impacts on the natural environment. The project also included parallel research into advanced measurement, automation and process control systems applied to treatment and valorisation processes. This research culminated in the development of a centralized management system capable of automatically and autonomously deciding on the sequence and control of new treatment stages for the wastewater streams under study
