Wastewater Treatment Process
Basic Features of the Treatment Process
- Aeration basins that provide for oxygenation and mixing of active microorganisms with raw sewage (the activation process).
- A basin or clarifier to separate solids from the treated effluent. Effluent is the term for liquid discharged from a treatment plant.
- Screens to remove debris from the raw wastewater as it enters the plant.
- A system to return solids (also known as activated sludge) from the clarifiers back to the aeration basins.
- A system to waste or remove excess solids from either the basin or clarifier thus controlling the solids mass.
Operational Controls
- Controlling the oxygen level
- Controlling the rate that activated solids are returned to the aeration basins
- Controlling the rate that solids are withdrawn from the process
Functions of the Process, or Treatment
- Oxidation of ammonia to nitrate
- Removal of carbonaceous organic material
- Removal of nitrate
- Removal of phosphorus
Treated Water Is:
- Filtered to remove nearly all of the remaining solids
- Chlorinated to kill any potentially harmful microorganisms
- De-chlorinated to eliminate excess chlorine that could be harmful to natural organisms when the water is discharged into a stream
Biosolids
Biosolids are sludge compounds that have been wasted or removed from the primary treatment process and pumped directly into a sludge lagoon. After spending the required amount of time in the sludge lagoons, biosolids are tested and applied to local farm land for crops such as Bermuda-grass, other types of hay, wheat pasture, etc. for stock feed.
