APRIA Systems manufactures a bioelectrochemical cell for the experimentation of the VIOE- project, which is coordinated by DAM and in which the AINIA technology center collaborates. The VIOe- project aims to develop an innovative process for the effective valorization of organic matter and nutrients present in the sludge and wastewater of WWTP through the integration of anaerobic digestion with a third-generation bioelectrochemical process, to which an autotrophic aquatic biomass culture system is coupled (https://www.dam-aguas.es/portfolio-posts/vioe/).
