The anaerobic digestion of complex organic matter has the potential to dramatically reduce fossil fuels use and to recycle nutrients for subsequent crop production. Control of anaerobic digestors has been one of the process limitations to more widespread use of this technology. SENTRY™ has solved the process monitoring problem with our bioelectric sensor that detects volatile (fatty) acids.     

When used as part of an advanced control strategy, SENTRY™ provides a unique measurement of biological activity that can be used to control pumps and valves and can simplify the design of feedstock mixtures to maximize key performance indicators.
