| ‘State Of the Art’ diffused aeration system is using FINE PORE BUBBLE MEMBRANE DIFFUSER. In this system aeration is effected by means of porous diffusers installed at the bottom of the tank. In the aeration process oxygen transfer takes place by molecular diffusion through the interface film between air and liquid and increases in proportion to the interface area.
For a given flow, the surface area increases and the rise velocity of the bubbles decreases with the number of the bubbles. This factor contributes to the higher oxygen transfer capacity of diffused aeration system.
Advantages :-
The following are the advantages of diffused aeration system over conventional aerators:
