1Overview of Filter Optimization Workshop Activities
2After 3.5 hours of classroom instruction, participants will be provided a “bag lunch”.
3While 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.
4The afternoon session consists of approximately 2 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.
5Once the filter backwash reaches high rate, participants take the bed expansion measurement with tools provided by the PADEP.
6One of the tools used during the demonstration training is a filter bed expansion tool.
7Participants work in groups with assistance from course instructors.
8After demonstrating filter bed expansion measurements, instructors demonstrate the proper techniques to perform a filter bed inspection, including core sampling of filter media.
9A filter inspection typically yields 5 filter core samples.
10Instructors provide participants with an interpretation of the core samples
11Finally, instructors demonstrate how to bag the samples for lab analysis.
