The main objective of the ENEDAR project is to improve the energy efficiency and sustainability of wastewater treatment plants (WWTPs) through the production and efficient use of biogas, biomethane, and biofertilizers by employing innovative and sustainable processes. Experimental laboratory-scale tests will be conducted to determine the optimal operating conditions for anaerobic digestion (AD) of WWTP sludge, biogas cleaning, and digestate treatment wetlands (DTW), utilizing innovative materials and processes such as iron nanoparticles encapsulated in carbon (OPS), photoacoustic sensors for volatile fatty acids (VFA) and CH4, and cost-efficient physicochemical biogas cleaning processes.
A pilot plant will be implemented and validated at the Almazora WWTP (Castellón), integrating each of the technologies optimized at the laboratory scale along with a cost-efficient cogeneration system to validate the energy utilization of the produced biogas and biomethane:
- Anaerobic digester operated with OPS and a photoacoustic sensor for VFA and CH4 to monitor potential inhibitions caused by accumulation in the biogas.
- Cost-efficient physicochemical biogas cleaning process for the simultaneous removal of CO2 and H2S.
- Digestate treatment wetland (nature-based solution) for the stabilization and mineralization of volatile matter and dehydration of the digestate.
- Energy utilization system for biogas and biomethane.
As a technology center specializing in water treatment technologies and process monitoring, AIMEN will develop photoacoustic sensors for VFA and CH4 to monitor the AD process and will contribute its expertise in AD and sludge treatment wetlands.
