Whether your project requires a compact aeration solution for a small STP or a large-scale industrial wastewater treatment system, we offer customized aeration solutions that meet every operational requirement.
What is a Diffused Aeration System?
A Diffused Aeration System is a wastewater treatment mechanism that introduces compressed air into water through specially designed diffusers. These diffusers release thousands of fine or coarse bubbles that increase dissolved oxygen levels, allowing aerobic microorganisms to effectively break down organic pollutants.
The system generally consists of:
Air Blower
Air Distribution Pipeline
Coarse Bubble Diffusers
EPDM Membrane Diffusers
Disc Diffusers
Tube Diffusers
Control Valves
Air Manifolds
Diffuser Supports
Together, these components create an efficient oxygen transfer process that improves biological treatment performance.
Working Principle of Diffused Aeration System
The operation of a diffused aeration system is simple yet highly efficient.
1. The air blower generates compressed air.
2. Air travels through PVC, SS, or HDPE pipelines.
3. Air reaches the diffuser network installed at the bottom of the aeration tank.
4. Diffusers release fine bubbles throughout the wastewater.
5. Oxygen dissolves into the water.
6. Aerobic bacteria consume the oxygen.
7. Organic pollutants are decomposed rapidly.
8. Clean and treated water moves to the next treatment stage.
The use of fine bubble technology significantly improves oxygen transfer efficiency compared to conventional surface aerators.
