Alberta Environment has set a new performance standard for particulate control in
drinking water, which sets a new challenge for Edmonton's water treatment plants. Based
on using particle-counting technology as a new measurement tool for the drinking water
industry, a new perspective for filter media design is required in order to be compatible
with the new technology. This paper summarizes the results from a filter media study that
included a pilot-scale phase 1 and a full-scale phase 2. This study was conducted from
2001 to 2002 to examine the performance of different filter media designs under a
stringent particle count standard. The purpose of this study was to find a filtration system
that can keep particle count levels in finished water well below the new standard. The
final suggestion of this study is a dual-media filter. This filter consists of a 550 mm
depth of sand with an effective size of 0.35 mm and a 200 mm depth of anthracite with an
effective size of 0.9 mm on the top of the sand. The E. L. Smith Water Treatment Plant
in EPCOR is upgrading its filter media by using this new filter media design to replace
the old filter media design in 2003. Includes 2 references, table, figures.
