Red Bud Wastewater Treatment Facility Improvements Project
PROJECT NAME: Wastewater Treatment Facility Improvements Project
OWNER: City of Red Bud
LOCATION: Red Bud, Randolph County, Illinois
FUNDING AGENCY: Illinois Environmental Protection Agency Low Interest
CONSTRUCTION COST: $1,100,000
YEAR COMPLETED: 2003
PROJECT DESCRIPTION: The City of Red Bud retained Rhutasel and
Associates, Inc. to upgrade their Wastewater Treatment Plant. The upgrades
include new screening and grit removal facilities, an excess flow clarifier with
chlorination facilities, additional aeration capacity for the activated sludge
treatment units, and complete re-painting and rehabilitation of one of the
existing activated sludge treatment plants.
Addition of the excess flow treatment unit will bring the plants hydraulic
capacity to 3.6 MGD with future addition of a third activated sludge plant.
Expansion of the activated sludge system is not required at this time, however
with the new expansion the hydraulic capacity of the plant will be capable of
handling the future addition when it is required.
The new raw wastewater cylindrical screening unit augers the screenings into a
disposal container, while it dewaters and compacts the screenings to minimize
the quantity of material to be disposed of. The vortexing aerated grit chamber
provides grit separation and washing. Grit is transferred from the chamber to an
auger type grit classifier which dewaters and consolidates the grit before
discharge to a disposal container. Grit is discharged into a wheeled dumpster
for easy removal from the headworks building. The 40 diameter excess flow
clarifier is designed to handle 1.8 MGD which provides capacity to handle the
projected hydraulic loadings far into the future. For ease in operation, a
multiple 150 pound cylinder manifold system is utilized for chlorination. The
chlorine system is activated when flow commences to enter the excess flow
clarifier. Following a storm event, the contents of the clarifier are pumped
back to the activated sludge units for processing.
Several years ago, coarse bubble diffusers were installed in the plants to
alleviate operational problems. This change required additional aeration for the
system to meet its full design capacity. Therefore, the new centrifugal blowers
were installed as part of the current upgrade to meet the future aeration needs
of the plant.
With the completion of these improvements, the City of Red Bud will have
adequate organic and hydraulic treatment capacity within its wastewater
treatment system to meet its needs far into the future.
