Peace of mind for high rate anaerobic reactors

Paques’ unique SENSOTRAQ® sensor monitors the health of your reactor in real time; like having an additional operator that never sleeps! SENSOTRAQ® is the only real-time biological sensor for monitoring the microbial health of high rate anaerobic reactors. The sensor measures the microbial metabolic activity of the microbes on the surface of the sensor. As these microbes consume easily biodegradable organics in the wastewater, they transfer electrons onto the SENSOTRAQ® sensor’s electrode. This activity produces a measurable electrical signal that correlates to the amount of biodegradable organic carbon in the vicinity of the electrode.
When the SENSOTRAQ® sensor is installed in the effluent or recirculation pipeline of a BIOPAQ® reactor, the electrical signal trends closely to the concentration of volatile fatty acids (VFAs), which is an indicator of the microbial health of high rate anaerobic reactors. An elevated signal (High-alarm) indicates high a VFA concentration in the wastewater stream. 

This data allows operators to continually monitor the health of their wastewater treatment process. Furthermore, this data can be leveraged with other water quality and operational data to improve/ optimize system performance.

The online SENSOTRAQ® dashboard allows users to visualize their biological reactor’s heath real time. The 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 or can be integrated with the existing SCADA system. Multiple installed electrodes can be visualized with the same login and dashboard allowing for a single location to visualize a network of installed probes.

Data produced from the sensor can be used to:
  • Constant 24/7 monitoring of the reactor health
  • Remote access from any device
  • Reduced physical testing, saving time and money
  • Operate reactors closer to full capacity
  • Provide an early warning system and avoid system shock
  • Assist operators to understand the patterns of the effluent stream
  • Mitigate upsets in advance and thereby reduce expensive downtime and restart costs where extra biomass is needed.
