This early morning I have listen a radio program here in Italy. The topic was "wastewater treatment with bacteria and electrons". Great!!! I thought, one more idea on wastewater treatment different than the traditional systems.
Here the link to the podcast:
radio link ( just in Italian) to RADIO 24 ILSOLE24ORE
I was also interviewed in the same radio few years ago.
Well, I promptly contacted the prof. that following this project, which has kindly responded.I have also know that he is a wetland's friend!!!
"Aquaelectra is a project funded through the programme INNPACTO from the Spanish Ministry of Science and Innovation.
This collaborative project has three objectives: to develop a natural system of sewage treatment using wetlands, to establish a bioelectric anaerobic treatment system for wastewater and to build a bioelectrogenic removal system of nutrients (nitrogen).
Bioelectrogenesis is a novel process by which certain bacteria can oxidize organic matter and transfer electrons generated directly to a solid surface conductive, for example, graphite so we can obtain and store clean energy.
Members of Aquaelectra are IMDEA-Water Institute (Bioelectrogenesis group), CENTA Foundation (Centre for New Water Technologies) and wastewater and water treatment companies JOCA, DAM and Euroestudios, responsible for coordinating the projec."

Scottish Water has invested £8.7 million in an aerated wetland scheme at Cowdenbeath to improve its combined sewer network.The water company has been working with reed bed specialists ARM Limited and Barhale Construction since September 2013 to design and construct a wetland scheme which will treat the spill flows from two Combined Sewer Overflows (CSOs) for attenuation and treatment before being discharged into the Lochgelly Burn.
Located to the south of Cowdenbeath Golf Course, the £8.7million project involved the construction of two units; the first a flow balancing shaft settlement system for sedimentation of solids and the second a 4,000m2, two metre deep saturated, vertical flow aerated wetland fitted with Forced Bed AerationTM (FBATM).
