Plant/Process Description:
The Delaware No. 1 Water Pollution Control
Facility is rated at 80 million gallons per day,
using an aerated activated sludge process.
Junction Chamber: Three underground pipes bring
influent to the junction chamber, where the three
flows mix before entering the Preliminary
Treatment Facility.
Preliminary Treatment Facility: In the
preliminary treatment facility, the wastewater
flows through bar screens which catch large solid
objects. The water then enters the grit chamber,
where small stones and sand settle out. The grit
and screenings are trucked to landfills. After
this stage, a large pump raises the wastewater
nearly 50 feet (15.24 meters) to begin its trip
through the gravity-fed treatment tanks.
Primary Sedimentation Tanks: Wastewater takes 12
to 15 hours to flow through the primary
sedimentation tanks. During this slow passage,
solids settle to the bottom of the tanks. These
solids, called "primary sludge", are skimmed off
the bottom and held for further processing. Oil
and grease scum is skimmed off the top of the
primary sedimentation tanks into scum
wells.
Delaware No. 1 Water Pollution Control Facility
has ten primary sedimentation tanks, measuring
about 186 feet by 50 feet with an average side
water depth of ten feet.
Aeration Tanks: In the aeration tanks, "primary
wastewater" coming from the primary sedimentation
tanks is mixed with oxygen and secondary sludge -
a mixture of dead microbes and bacteria coming
from the final sedimentation tanks down the line.
The wastewater spends four hours in the aeration
tanks.
There are eight aeration tanks at Delaware No. 1.
Each tank is about 220 feet by 55 feet, with an
average liquid depth of 15 feet. Mechanical
surface aerators are used to mix the activated
sludge, the primary wastewater, and the
oxygen.
Oxygen Facilities: The CCMUA uses oxygen in its
treatment process because the land available for
the treatment plant is quite limited.
Final Sedimentation Tanks: In the aeration
tanks, the bacteria have formed clumps as they
grow and consume solids. Here in the final
sedimentation tanks, these clumps are allowed to
settle to the bottom forming secondary sludge.
Secondary sludge is more liquid than primary
sludge. It is composed of small particles. About
30 % of the secondary sludge is recycled to the
aeration tanks. The rest is removed for further
processing.
Delaware No. 1 WPCF has eight final sedimentation
tanks. Each is about 270 feet long by 78 feet
wide.
Chlorine Contact Tanks: The final stage of
treatment takes place in the chlorine contact
tanks. To kill any remaining bacteria, the water
is mixed with a solution of sodium
hypochlorite.
Outfall: The treated wastewater is discharged
through an outfall pipe into the Delaware River.
It has spent about one full day passing through
the treatment plant.
