This digital sensor is suitable for real-time pH value monitoring in industrial wastewater, water works, food processing, pharmaceutical, and other industries. It integrates electronic circuits and microprocessors inside the sensor.
These bio-electrode sensors (BES) allow you to reliably measure and monitor the changing BOD or VFA concentrations in wastewater. IT has a sensor biofilm which is customised to the following applications: wastewater collection networks, influent locations of wastewater treatment facilities, anaerobic selectors for biological nutrient removal, and anaerobic digestion environments. The sensors monitor biological oxidation of organic carbon in wastewater streams by measuring the rate at which in-situ and customised biofilm surfaces consume the available food. A biofilm is established on the sensor after 1-3 days in the wastewater stream. This bio-electric surface then uses the sensor current collector to generate a flow of electrons that is equivalent to the rate of organic carbon oxidation. This flow of electrons is measured and displayed on an online dashboard and updated every minute. Increasing BOD in wastewater will result in increased metabolic activity and sensor signal; acute chemical toxicity or significant dilution of BOD will result in low alert signals and reduce metabolic activity. This results in reliable, real-time insight into biological treatment rates and performance. These microbial, fuel cell-based sensors are robust and are used in the most challenging situations. Very little maintenance or cleaning is required. It highlights microbial activity variations, organic matter degradation, and process upsets, which can guide your operations.
