Plant/Process Description:
The San Angelo Wastewater Treatment Plant is a
Conventional Activated Sludge Treatment Plant
that treats an average of 9 to 10 million gallons
per day. The plant uses three Anaerobic Digesters
for sludge stabilization. The treatment process
consists of the following steps:
1. Lift Station: All of the wastewater from San
Angelo flows into a wet well located at the
wastewater treatment plant. The wet well
contains large pumps that pump all the
wastewater to the head works of the plant.
2. Mechanical Bar Screens: There are two
mechanical bar screens located at the beginning
of the head works. These bar screens are set on
times to operate every 15 minutes. The bar
screens have square tubing spaced approximately
one inch apart. Any large rags or debris is
stopped by these bar screens. The bar screens
have large mechanical rakes that clean the
debris off the bars and deposits them into a
dumpster for disposal in the landfill.
3. Grit Removal: There is a grit removal system
after the wastewater goes through the bar
screens. Here sand, gravel, etc., are removed
from the system and taken to the landfill for
disposal.
4. Primary Clarifiers: There are four primary
clarifiers that slow the flow of the water down
to allow very fine particles to settle out. The
sludge that settles to the bottom of the
clarifiers is pumped to the digesters for
stabilization. The effluent from the primary
clarifiers flows into aeration basins for further
treatment.
5. Aeration Basins: There are two aeration
basins. Each basin contains over 3,000 ceramic
fine bubble diffusers. The diffusers act just
like an air stone in a fish tank. Air flows
through the diffusers to provide oxygen for the
aerobic bacteria in the aeration basins. The
aerobic bacteria thrive in the presence of oxygen
and feed on the organic matter in the water thus
removing pollutants in the water.
6. Final Clarifiers: There are four final
clarifiers that slow the flow of the water down
to allow the sludge from the aeration basins to
settle out. The sludge settles to the bottom of
the final clarifiers where most of it is
recirculated to the aeration basins to maintain
an adequate level of aerobic bacteria. The
cleaned wastewater flows into a wet well for
pumping to the holding reservoirs. The water
from the reservoirs is either pumped to the Tom
Green County Water Control and Improvement
District located in Veribest for irrigation or
is irrigated at the city's farm.
