| Treatment Process | Function |
| Raw wastewater enters the plant and begins pretreatment | |
|
Flow Meter Screening Grit Removal Comminution |
Measures and records flow Removes large objects Removes sand, gravel and other inorganic material Shreds material so it can be easily treated Raw sewage is moved by pumps operated by a control panel. |
| After pretreatment the wastewater is pumped to begin secondary treatment | |
| Pre-Aeration | Freshens the wastewater by adding oxygen through pumping air into the aeration tank. (empty tank showing air heads) |
| Aeration Tanks | Provides contact between the raw sewage and activated sludge, which contains millions of bacteria and other microorganisms that stabilize the waste and produce a settleable material. |
| Clarifiers | Sludge is settled from the water in the tank of the clarifier. |
| Aerobic Digesters | Sludge that settles from the clarifiers is pumped to different locations. It is either returned to the aeration tanks or placed in the digesters or reedbeds where different organisms stabilize it to produce biosolids which are then used for their soil conditioning and fertilizer value. The biosolids are removed from the plant in a tanker truck. |
| Contact Tanks | Water is disinfected to kill any disease-producing organisms before being discharged to the river. The quality of the water is tested on a regular basis. (Disinfection chemical regulator) |
