Resumen: [EN] This research work proposes an innovative layout for urban wastewater treatment based on anaerobic
technology, microalgal cultivation and membrane technology. The proposed Water Resource
Recovery Facility (WRRF) system can treat urban wastewater efficiently, complying with legal
discharge limits and allowing for resource recovery, i.e. energy, nutrients and reclaimed water. In
addition, the proposed layout produces less solid wastes than a conventional wastewater treatment
plant (WWTP) and it is possible to recover energy as biogas, not only from the original wastewater
sources but also from the biomass generated in the WRRF system.
