Activated sludge process:
- The essential features of the activated sludge process are an aeration stage, solids-liquid separation following aeration, and a sludge recycle system.
- Wastewater after primary treatment enters an aeration tank where the organic matter is brought into intimate contact with the sludge from the secondary clarifier.
- It requires less space, does not produce obnoxious odor, and requires less time for wastewater treatment.
- It requires skilled supervision

Activated Sludge Process:
The activated sludge process is a type of wastewater treatment process that uses a combination of biological and physical processes to treat sewage and industrial wastewater. It is a widely used method for treating both municipal and industrial wastewater.
Aerobic Suspended Growth System:
The activated sludge process is an aerobic suspended growth system, meaning that the microorganisms responsible for treating the wastewater are suspended in the wastewater and are in contact with the organic matter that needs to be treated. The microorganisms use oxygen to break down the organic matter, converting it into carbon dioxide, water, and more microorganisms.
Process Description:
In the activated sludge process, wastewater is mixed with a culture of microorganisms in aeration tanks. The microorganisms feed on the organic matter in the wastewater, reducing its concentration. The mixture is then passed into settling tanks where the microorganisms settle out as sludge. Some of this sludge is returned to the aeration tank to maintain a high concentration of microorganisms, while the rest is disposed of or treated further.
Advantages of Activated Sludge Process:
- Highly effective at removing organic matter and nutrients from wastewater
- Can be used to treat a wide range of wastewater types
- Relatively low operating costs compared to other treatment methods
- Can be easily scaled up or down to accommodate changes in wastewater flow or composition
In conclusion, the activated sludge process is an aerobic suspended growth system that is widely used for treating municipal and industrial wastewater due to its effectiveness and versatility.
