Area of Science:

  • Environmental Science
  • Analytical Chemistry
  • Biotechnology

Background:

  • Biochemical Oxygen Demand (BOD5) is a critical water quality indicator.
  • Traditional BOD5 measurements are time-consuming, requiring 5 days.
  • There is a need for faster, reliable BOD5 assessment methods.

Purpose of the Study:

  • To develop a rapid BOD5 sensor using microbial fuel cells (MFCs).
  • To integrate artificial intelligence (AI) for accelerated BOD5 prediction.
  • To validate the sensor's performance in real-world applications.

Main Methods:

  • Utilized microbial fuel cells (MFCs) as the core sensing platform.
  • Developed and implemented an artificial neural network (ANN) model.
  • Correlated MFC output with standard BOD5 measurements for ANN training.

Main Results:

  • Achieved BOD5 predictions within 6-24 hours.
  • Attained an average prediction error of 7%.
  • Demonstrated the AI-MFC/BES sensor's viability for practical use.

Conclusions:

  • The AI-MFC/BES sensor offers a significant reduction in BOD5 testing time.
  • The developed system provides accurate and rapid water quality monitoring.
  • This technology shows promise for real-time environmental assessment.
