What is Aeration ?

by Team Goseeko

Aeration process the oxygen is absorbed and carbon dioxide is released. It reduces the percentage of carbon dioxide up to 70% and this helps to reduce the chances of corrosion of the water carrying pipes. 


Aeration method in the water to be treated is brought in close contact with air. up to some extent due to agitation of water in the aeration process some of the bacteria get killed. As hydrogen sulphide is easily removed in this process , the odour is removed. The iron and manganese in the water also is oxidized in the process of aeration.


  1. The Aeration method can not remove 100 % of carbon dioxide so its residue always remains in small quantities.
  2. Excessive aeration leads to the excessive absorption of oxygen which leads to the increase the property of corrosiveness of water which needs to have a deaeration process.


There are four methods of Aeration:

  1. Air diffusion
  2. Cascade
  3. Spray nozzles
  4. Trickling beds

Air diffusion:

The aeration of water is activated when the air bubbles start passing in the upward direction.


It is free fall of water. The water is allowed to fall at a height of 1 to 3 m and the water runs in the downward direction over three or four steps made up of cement or metal.

Spray nozzles:

The water sprinkled through the nozzles up to the height between 2 to 2.5 m . This is very useful to remove about 90% of carbon dioxide.

Trickling beds:

In this method beds of coke or slag supported by the perforated trays are prepared. The water carried by the pipes is allowed to trickle down through the beds.
