• discharges into Lake Lanier,
Gwinnett County
• 60 MGD (227,000 m3/d)
• One of the world's largest
ultrafiltration plants
The advanced water reclamation
facility, the F. Wayne Hill Water
Resources Centre, about 30 miles
north of the city of Atlanta, Georgia,
receives mostly residential infl uent
wastewater, and discharges
reclaimed water into Lake Lanier,
a US Army Corps of Engineers
impoundment located on the
Chattahoochee River. Lake Lanier
is the drinking water supply source
for Gwinnett County, and the Atlanta
metro region. Gwinnett County's Shoal
Creek Filter Plant water intake is located
less than one mile away from the
discharge point within the lake.
The water treatment consists of
primary and secondary biological
treatment and two parallel trains
of tertiary treatment. One of the
parallel trains includes chemical
clarifi ers and granular media fi lters,
and the other consists of chemical
clarifi ers and ultrafi ltration. A er
this, water is blended prior to initial
ozone disinfection, biologically
active carbon fi ltration, and fi nal
ozone disinfection before discharge
by a pipeline to Lake Lanier and the
Chattahoochee River.
The plant uses packed-tower wet
scrubber technologies for odour
control for its preliminary, primary
and secondary treatment systems.
The use of ultrafi ltration membranes
for tertiary treatment makes this one
of the world's largest ultrafi ltration
plants.
