Submerged Media AerationBack to Services
In the Submerged Media Aeration system, digestion of organic matter shall take place by biological-aerobic process.
The bacteria responsible for digestion process are present in the form of fixed film.
Geometrically structured PVC media is provided for immobilization of bacteria.
The PVC media has a very large specific surface, which ensures enormous surface area for the immobilization of bacteria.
The Submerged Media Aeration chamber is partially packed with structured media fill of PVC.
This specialty of the media lies in offering very large surface area at a void ratio of 95%.
The surface area provided by media is around 95-105 m2 per m3.
The entire media remains submerged in the reactor content.
The bacteria grow and reside on large surface area provided by media.
The bacteria developed on media surface takes upon organic content of wastewater to metabolize it and produce biomass.
Aeration in SAF shall be done by twin lobe blowers. Air shall be provided through fine bubble diffusers to provide desired oxygen to microorganisms.
