This event is limited to the first 25 registrants. Lunch is included and 7 Professional Development Hours (PDHs) will be awarded for attending this event.


Course Description:

Morning classroom session on filter surveillance techniques followed by hands-on activities at a filter in the field to demonstrate filter surveillance techniques.

Attendees will be guided to self-perform tests that comprise a long-term filter surveillance program.

Hands-on tests will include:

  • Filter media sampling techniques
  • Spent backwash turbidity analyses
  • Media depth profiling for effective size and uniformity coefficient (off-site testing) and solids retention analyses

An important part of the field segment will be training on visual observations and what they may mean relative to the condition of the filter and its operational efficacy. Component condition assessment will be briefly reviewed.

During the afternoon, data gathered during the hands-on exercises will be trended and discussed.
