El Hamico designs and validates an innovative, low-cost, on-site, and ecological bioremediation solution, suitable to sewer pipes, artificial channels and streams, and thus at improving the security and the quality of degraded urban river while lowering the bioremediation costs. El Hamico proposes a new electrochemical way of controlling and directing microbial functioning toward some goals expected by human, by the management of anode potential. Additionally, it not only will pave a new way to new bio-remediation technologies and will develop innovative tools and methods of the water management and effluent, its management concept of microbial populations and activities may be extended to all processes requiring control of anaerobic microbial functioning. To have an operational objective allowing directing our project towards real applications, El Hamico focuses on environmental applications: the management of microbes involved in the biodegradation; but it could have applications in the food and health fields, wherever the selection and monitoring of microbial populations and their functioning are needed.
