A new generation of Microbial Electrochemical Wetlands

Unleashing the small community economies potential through innovative wastewater treatments technologies and standing ready for further replication and market uptake, iMETland was born locally but incorporates a global applicability potential. Innovation stands in the creation of a virtuous circle connecting water, energy, ICT and land resources, safeguarding the surrounding environment. The project aims to construct and validate a full-scale application of an eco-friendly device to treat urban wastewater from small communities at zero-energy operation cost and generate pathogens-free water suitable for irrigation. Four different geographical locations, with very different climate conditions, will be the demonstration areas of the iMETland units: Mediterranean (Spain), North-Europe (Denmark), South-America (Argentina) and North-America (Mexico).

The concept comes from the integration of Microbial Electrochemical Technologies (MET) with the biofilter concept used in constructed wetlands. The combination of electroactive bacteria with innovative electroconductive material leads to outperformance of classical biofilters, resulting in 10-fold higher depuration rates than classical techniques.

 

The consortium with 11 partners from 7 different EU member states and two associated countries (Argentina and Mexico) is led by Spanish IMDEA AGUA as project coordinator. Further partners are Aqua-Consult Ingenieros, Fundación CENTA, PriceWaterhouseCoopers and Piroeco Bioenergy (Spain); Aston University (United Kingdom): Aarhus Universitet and Kilian Water (Denkmark); the media agency Youris (Belgium); INTEMA (Argentina) and IMTA (México).

The unique conversion of sewage treatment into electric current by electricity-producing bacteria makes such a process an internal reporter of the biological treatment. This can be used as output signal to control the process and can easily inform the operator through ICT tools, converting the depuration in an interactive process between device and a smart-phone in end-user´s hands.

iMETland try to fill the gap that was sharply identified by the programme topic WATER-1-2014/2015: Bridging the gap: from innovative water solutions to market replication. The proposed solution has already passed both research and pilot scale and is ready to try a full-scale demonstration to accelerate the market uptake. The multidisciplinary nature of iMETland makes it to fit well with the water and wastewater treatment priority of the EIPwater.

With a budget of 3.5 Million euro over three years, the project brings together European and international universities, research institutes and companies, with strong expertise and experience in the technological fields of wastewater treatments, microbial electrochemistry, ICT, carbon materials, but also on business development and communication. iMETland partners conveyed in Alcalá de Henares on 5th-6th of November to set up a collaborative workflow and kick off the first activities of the project.
