Ceit-IK4 is participating in the Life ANADRY project, whose aim is to solve the environmental problems associated with the generation of sewer sludge in urban wastewater treatment plants (WWTP)
The continuing increase in the treatment of municipal wastewater in Europe has in recent years yielded cleaner rivers and better quality water. But the inappropriate handling of the sewer sludge produced by wastewater treatment plants can have a serious impact on the environment.
In a bid to improve the treatment of sewer sludge in small- and medium-sized WWTPs, the Life ANADRY project, of which Ceit-IK4 is a participating member, was launched in September 2015. The project will use dry anaerobic digestion technology in a pre-industrial prototype (20 m3) to demonstrate the viability of the process in situ.
What happens to the sewer sludge generated in WWTPs? Typically it is put into landfills or used in agriculture as fertilizer, but if the sewer sludge is not treated properly it can create environmental problems such as the propagation of pathogens or uncontrolled CO2 emissions.
The ANADRY technology will make it possible to treat sewer sludge from urban WWTPS in a more technically and economically viable manner, thus providing a more sustainable solution relative to current approaches. European legislation is behind a drive to make sewer sludge treatment more environmentally-friendly and more beneficial for human health. To that end, it is expected that the application of the ANADRY technology on a larger scale will be a key component in helping hundreds of WWTPs across Europe comply with current legislation.
This project has received funding from the European financial instrument for the Environment (Life+) programme (LIFE14 ENV/ES/000524).
