Globally there are over 100,000 installed advanced wastewater treatment facilities and industrial anaerobic digestion systems.
Toxic shock, system imbalance and poor performance result in regulatory fines and reduced revenue from biogas production. 
is a unique bio-electrode sensor technology that provides real-time microbial performance monitoring in anaerobic and aerobic wastewater treatment systems.

Key Benefits 
Monitor WWTP process stability
Real-time bio-electrode data allows operator to monitor microbial health of the WWTP.
 Protect the WWTP from upset
 Imbalance or toxic shock events can be identified the instant they begin to impact microbial activity. This allows the operator to take immediate action and reduce negative impacts on system performance.
Optimize process
Aggregation of data and integration with existing water quality and process information provides unique insights into system performance over time.
What are the problems faced by industrial anaerobic digestion systems? 
Imbalance Events
System imbalance and failure can cost thousands of dollars per event to fix. 
Toxic Shock
 Imbalance or toxic shock events can be identified the instant they begin to impact microbial activity. This allows the operator to take immediate action to reduce impact on system performance.
Poor Performance
Aggregation of data and integration with existing water quality and process information provides unique insights into system performance over time.

The                          Solution
Jack Ambler presents SENTRY to wastewater industry professionals
SENTRY is a real-time bio-electrode sensor that allows for the monitoring of microbial metabolic activity in the anaerobic and aerobic wastewater treatment systems.
 
The data allows operators to monitor the impact of toxic chemicals or process imbalance on microbial health in the WWTP system. Additionally, this data can be aggregated and combined with existing water quality and operational data to improve and optimize WWTP system performance.
Patrick Kiely explains the benefit of SENTRY for Anaerobic Digestion
 
Product focus
SENTRY leverages bio-electrochemical sensor technology to relay bio-activity (metabolic activity) of the microbiology to the wastewater system operator. This data allows operators to continually monitor the microbial stability (health) of their wastewater treatment process. Furthermore, this data can be leveraged with other water quality and operational data to improve/optimize system performance. 
Data produced from the sensor can be used to:
 
1. Predict process upset via instability in microbial metabolism
 
2. Correlate fluctuating bio-electrode output to system input / process / operational events
 
3. Aggregate data to determine daily, weekly, and monthly performance patterns
Bio-electrochemical systems (BES) are a novel technology that rely on bacteria that use insoluble metal deposits as electrons sinks during the anaerobic consumption of organic substrates. By substituting an electrode for the metal deposits, electrical current can be recorded. The generated bioelectric current is the product of microbial metabolic activity of exoelectrogenic bacteria involved in the wastewater treatment process. The obtained biological data is instrumental in understanding the impact of water quality (pH, nutrient content) and operational parameters (temperature, flow rate, organic load) on the biological process’s efficiency, and resulting system performance.
The online dashboard allows users access to visualize microbial-electrode metabolic activity in real time.
 
Data is presented with user options to view on hourly, daily, weekly, monthly or customized intervals.
 
Data can be selected and downloaded in CSV format for off-line data analysis. Multiple installed electrodes can be visualized with the same login and dashboard allowing for a single location to visualize a network of installed probes or systems.  
System installation
The SENTRY can be installed in both in-line or drop in locations. The in-line sensors are installed and connected through a 1.5” NPT fitting into a pipe with at least 2” in diameter. Typical installation for a single probe is in the recirculation line of the
anaerobic tank, but if sequential tanks are present - for hydrolysis, acidogenesis etc. – a probe installation in each tank is recommended.
In-line 
The SENTRY can be EASILY installed into existing re-circulation lines using standard industry fittings. 
Drop-in
The SENTRY can be added to existing tanks. IWT can provide custom mounting solutions suitable for each install location and environment if required.
Performance Data
Microbial performance monitoring data is processed and clearly communicated to the site or system operators.
We see great promise for the SENTRY sensor. Real-time data provides a means to monitor influent loading and how the plant is handling the load and the subsequent effluent quality. Seeing data in real-time allows for timely adjustments and a means for continuous influent and effluent quality monitoring.
