Early Warning System for Anaerobic Digesters

Posted by Consejo Superior de Investigaciones CientíficasResponsive · Patents for licensing · Spain

Summary of the technology

The CSIC and University Pablo de Olavide have developed a system for warning possible failure of
the anaerobic digestion process carried out in a digester, using a microbial fuel cell connected to
the digester by recirculation. This system is called Previous Destabilization Alarm for Anaerobic
Digesters (PDAL).

Companies interested in the license of the patent are searched for commercial exploitation.

Immediate fault detection and early correction


PDAL system diagram Anaerobic digestion is a process for the treatment of organic waste carried out by the action of microorganisms, that operating in the absence of oxygen, transform these residues into biogas. This is a very sensitive process due to the high number of factors that affect the activity of the microorganisms, and that could cause failures in the process.
The PDAL system allows to anticipate possible critical, or even irreversible, failures of the anaerobic digestion process in real time, by measuring the electrical potential generated in the microbial fuel cell, which is directly related to the microbial activity of the microorganisms present in the reactor. When significant variations of this electrical potential are produced the system issues a failure warning before the destabilization of the process is irreversible.

Main innovations and advantages


· The detection of anomalies in the process is immediateindependently of the kind of anomaly.
· The PDAL system allows implementing an early action ofcorrection of failures.
· The inoculation of the device does not require priormanipulation or extraction of the digester content.
· The microorganisms present in the device are the same asthose of the digester.
