ELKHORN RUN PLANT WASTEWATER TREATMENT PROCESS
Wastewater from more than 4,600 homes and businesses drain into Center Township Sanitary Sewer System.
The main sewer interceptor is an eighteen (18) inch line that carries approximately 1.14 million gallons of wastewater a day
to the Elkhorn Run Treatment Plant.
The comminutor reduces the size of solid chunks by shredding.
Through a settling process, bacteria used in the aeration basins are seperated and collected in the clarifiers then returned to the aeration basins for continued treatment. The settled sludge is pumped to a sludge digestor. In this tank, sludge is placed to allow decomposition by micro-organisms under aerobic conditions.
The clean water passes through the chlorine tanks where it is disinfected.
Most clean water is discharged into the Ohio River. The rest is used by the plant for various reasons.
From the sludge digestor, the sludge passes through a belt filter press which removes the excess water from the sludge. The sludge is then sent to a landfill.
As the wastewater passes through the various stages of treatment, tests for a variety of critical process indicators are conducted at the Elkhorn Plant's on-site DEP Accredited Laboratory.
