Aeration in an activated ...

Aeration in an activated sludge process is based on pumping air into a tank, which promotes the microbial growth in the wastewater.The supplied oxygen is utilized by bacteria in the wastewater to break down the organic matter containing carbon to form carbon dioxide and water. Without the presence of sufficient oxygen, bacteria are not able to biodegrade the incoming organic matter in a reasonable time

 The microbes feed on the organic material; forming flocks and removing organic nutrients and finally settled down as sludge. This can easily settle down.

 Carbon source material is following

1. Add Molasses as a carbon source.
2. Carbon source like methanol
3. Circulation of the bacteria by circulation amount of water.” The portion returned to the aeration tanks is called Return Activated Sludge.”
4. Add phosphoric acid to promote bacteria.
5. Backwash water can be taking.
6. Air given by sparser for equal and better distribution.

Monitoring dissolved oxygen in the water ensures that the Blowers are supplying enough oxygen for microorganisms to survive and carry out aeration wastewater treatment
