BACKGROUND
QUICK FACTS:
>FLOW RATE: 14 MGD
>PERMIT:
NH3-N < 1 mg/l, NOX-N < 2 mg/l
The 14 MGD Falling Creek WWTP, is a sister plant to the
Proctor’s Creek WWTP owned and operated by Chesterfield
county. Like Proctor’s creek it’s effluent finally flows into the
Chesapeake Bay, due to which the facility is required to meet
identical effluent standards as Proctor’s Creek. Ammonia
nitrogen and nitrate plus nitrite nitrogen leaving the plants
must be less than 1 mg/l and 2 mg/l respectively.
>NUMBER OF UNITS: 3
>START DATE: March 2009
Infilco Degremont inc. has used it’s Meteor®
process identical to Proctor’s Creek, which
utilizes floating biofilm carriers in association
with conventional activated sludge so that the
plant’s existing aeration basins can be modified
to meet the new stringent effluent standards
without the need for new construction. The
existing basins have been modified with baffle
walls so that treatment can be achieved entirely
within the original structure. The full scale facility
was designed in association with the county’s
consultant, Malcolm Pirnie Inc.
