The document provides an overview of activities at a filter optimization workshop. After classroom instruction, participants eat lunch while watching a training video on filter surveillance techniques. The afternoon consists of hands-on demonstrations in a filter gallery, starting with observing a backwash and then taking bed expansion measurements. Participants work in groups with instructors to demonstrate proper techniques for filter bed inspections, including core sampling and interpreting samples.

1. Overview of Filter Optimization
Workshop Activities

2. After 3.5 hours of classroom instruction, participants will be provided a
“bag lunch”.

3. While eating lunch, participants observe a 32 minute AWWARF training
video entitled “Filter Surveillance Techniques for Water Utilities”, this
helps prepare them for the afternoon filter inspection activities.

4. The afternoon session consists of approximately 2.5 hours of hands-on
demonstrations within the filter gallery. It starts with observation of an
actual filter backwash.

5. Once the filter backwash reaches high rate, participants take the bed
expansion measurement with tools provided by the PADEP.

6. One of the tools used during the demonstration training
is a filter bed expansion tool.

7. Participants work in groups with assistance from course instructors.

8. After demonstrating filter bed expansion measurements, instructors
demonstrate the proper techniques to perform a filter bed inspection,
including core sampling of filter media.

9. A filter inspection typically yields 5 filter core samples.

10. Instructors provide participants with an interpretation of the core samples

11. Finally, instructors demonstrate how to bag the samples for lab analysis.
