Anaerobic Digestion

Anaerobic Digestion

Is digester souring and expensive downtime affecting your biogas production?

Wish you had reliable, real-time insight into your digester’s organic loading?

Want a no-touch monitoring solution that does all this for as little as $40 a day?

At SENTRY, we’ve solved the process monitoring problem with our

bio-electrode sensor platform that detects VFAs for industrial, agriculture, F&B, municipal, and co-digestion facilities. And what’s different about our robust sensors is that they are mounted right in the effluent or recirculation lines of digesters, uniquely providing a minute-by-minute signal indicating the health of the microbial population degrading the wastes.

The SENTRY monitoring signal can be used to optimize biogas production while maximizing volatile solids destruction. By integrating our signal in your process control strategy, you can produce the most value from the digestion process.

When used as part of an advanced control strategy, our metabolic performance monitoring platform 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.

Many communities are faced with decreasing landfill capacity and excess digestion capacity. The nexus of these two issues has led to the idea of digesting organic wastes at a municipal wastewater treatment facility. Dubbed "co-digestion," this approach to waste management can benefit all interested parties.

The ability to digest wastes trucked to a municipal facility relies on active monitoring of the digestion process. We uniquely provide a robust technology to monitor the accumulation of VFAs in the digester. This data can be used to create digester feeding regimes that maximize biogas production and volatile solids destruction, while avoiding costly "upsets" to the digestion process.

Like municipal AD implementations, agricultural ADs are also all about the quantity and quality of produced biogas and generating as much revenue from a plant as possible.

The production and processing of crops and livestock often generates wastes that are difficult to handle, have detrimental environmental impacts if left untreated, and yet have significant nutrient value when properly recycled. Anaerobic digestion of those waste products reduces environmental effects while generating a revenue stream.

From meat and dairy products to grains and fruits, each wastewater type has a unique fingerprint that corresponds to the products and the methods used to treat it. We uniquely provide a real-time estimate of organic matter and can help production staff operate processing equipment to minimize losses and save on waste treatment costs.

During food processing operations where water is used in the preparation, blending, or clean-up operations, organic matter may be dissolved into the water. Our sensor platform is used to measure the impact of each successive step in the process, and will allow management staff to evaluate methods, materials, machinery, and manpower. That evaluation can lead to improvements that reduce waste and increase profits.

At SENTRY, we uniquely provide you with a leading indicator of digestion performance. A rising SENTRY signal is an indication that volatile acids are accumulating, and the methanogenic population is not effectively converting the volatile acids to methane. Our bio-electrode sensor platform can reduce the frequency of analysis by using our signal as a proxy for VFA concentrations in the digesters. In turn, this information can be used to regulate food wastes added to the digesters for the purposes of maximizing tipping fees and biogas generation and sale/use.

“SENTRY sensors showed us an upset event several days before our traditional sampling metrics gave us a warning. This several day warning could be the difference between us losing a digester or not.”
