This project aims to explore the electron donor capacity of vegetal waste for promoting nitrate reduction (denitrification) in bioelectrochemically-assisted constructed wetland (so-called METland®).
Our modus operandi includes the exhaustive analysis of potential materials through a circular economy strategy. We are treating real wastewater from IMDEA water headquarters using a denitrifying prototype of METland® in combination with ultrafiltration. We are also exploring the microbial communities responsible of coupling electrons from waste and nitrate reduction.
We expect to setup the operation conditions for generating a nitrogen-free high quality effluent from an office building that may serve as inspiration for future implementations.
