Diffused Aeration System

Air from a blower will be diffused through a Diffuser grid. It consists of porous membranes of dia disc or tubular type diffusers made of EPDM material.
The diffusers are of non-buoyant type, which during shutdown condition contracts to prevent any back-flow.
Diffusers are designed to ensure uniform permeability and to produce a flow of fine air bubbles and provides high contact area and more contact time due to slow rise of the bubbles which makes the system very efficient in terms of oxygen transfer efficiency thus low installed HP for the blower drive and hence low operational cost.
