Optimizing Filter Performance: Surveillance, Data Analysis, and Maintenance

Authors:

  • James DeWolfe - Hazen and Sawyer

This hands-on workshop, located at the Marston Water Treatment Plant, provides access to state-of-the-art equipment and techniques under the supervision and guidance of industry experts. The workshop will begin in a classroom setting composed of three interactive lectures emphasizing the importance of basic filtration protocols. The workshop then moves into forensic filter surveillance techniques and how to perform the analysis using simple tools and data collecting techniques. All participants will be involved in data analysis and reporting back on findings.

Learning objectives include:

• Deeper comprehension of the principles of granular media filtration
• Enhanced appreciation of filter maintenance and troubleshooting and other aspects of gravity filtration design and operation
• Understanding backwash fundamentals including: hydraulic loading rates, run time, applied and effluent water quality, low flow, high flow, and air scour, temperature effect on backwash, and when “clean is too clean”.
• Ability to apply filter surveillance techniques including: value of optimizing filtration, how to measure progress, what parameters to monitor, what tools and techniques are important, safety considerations, skills to assess filter efficiency, and comparative data analysis.
