SENTRY Real-Time Monitoring Protects Your Wastewater Treatment Plant from Disruptions Caused by Heavy Rain

Rain can significantly disrupt the activated sludge process in a treatment plant. Case studies show that even 10 mm of precipitation can temporarily impact the BOD value in the influent—with effects measurable at the effluent for over 24 hours. This demonstrates how critical even seemingly minor changes in the inflow can be.

Overview of Process Engineering Impacts:

• Dilution: Rainwater reduces the concentration of organic substances needed by microorganisms in the activated sludge process.
• Sludge Washout: Activated sludge can be washed out of the biological treatment stage.
• Reduced Contact Time: A decreased hydraulic retention time limits the period available for the degradation of organic matter.
• Nutrient Deficiency: Diluted wastewater leads to fewer available nutrients, which restricts microbial activity.

This is where the advantages of SENTRY probes come into play: With SENTRY sensors, such effects can be detected in real time. You receive timely data that enables optimal control of your plant—even under rapidly changing influent conditions.
