The NILEDAR research project aims to improve biogas production from sludge from the Tudela WWTP by applying zero-valent iron nanoparticles encapsulated in a carbon matrix (also known as OPS), obtained from a residue from olive oil production (vegetable water).
The tests will be conducted in two 2,780-L anaerobic digesters with a continuous recirculation heating system via a heat exchanger, a mechanical agitation system, and a recirculation feeding system. Tests will be conducted in parallel in the mesophilic and thermophilic ranges, meaning each digester will operate at a different temperature while the remaining parameters will be identical (agitation, VCO, feed, OPS dosage, etc.).
The project’s research team is composed of NILSA personnel in collaboration with SMALLOPS.
