Guidance Manual for Monitoring Biological Filtration of Drinking Water

Operators have a pressing need for practical drinking water biological filtration monitoring tools that provide rapid feedback. Additionally, clear guidance is needed on sampling, analysis, and interpretation of biological process data. To address these needs, WRF’s project 4620, Guidance Manual for Monitoring Biological Filtration of Drinking Water, extensively evaluated six biological process monitoring tools:
  • Biofilm formation rate
  • Dissolved oxygen consumption
  • Adenosine triphosphate
  • Adenosine monophosphate
  • Extracellular polymeric substances
  • Microbial community analysis

The tools were evaluated based on usefulness, data quality, ability to implement, and cost. Our presenters provided an overview of the monitoring tools, provided guidance on sampling and analysis methodologies, demonstrated the responsiveness of each tool to controlled pilot-scale experiments to enhance or attenuate bioactivity, and summarized results from an extensive evaluation of water quality and performance data at 12 full-scale facilities. This webcast will be of interest to operators and anyone in the drinking water community.
