The 6" (150 mm) EPDM Fine Bubble Disc Diffuser is a high-performance aeration device designed to deliver efficient oxygen transfer in biological wastewater treatment systems. It generates thousands of fine air bubbles that maximize oxygen dissolution while minimizing blower energy consumption, making it an ideal choice for Sewage Treatment Plants (STP), Effluent Treatment Plants (ETP), MBBR, SBR, and activated sludge systems.
Manufactured with a durable engineering plastic body and a premium EPDM membrane, the diffuser offers excellent resistance to wear, corrosion, and a wide range of wastewater conditions. The self-sealing membrane prevents sludge backflow when the air supply is stopped, ensuring reliable operation and a longer service life.

🔧 Installation & Operating Guidelines
- Install the diffuser securely on compatible diffuser pipes or aeration grids.
- Ensure the threaded connection is properly tightened to prevent air leakage.
- Flush air piping before commissioning to remove debris.
- Operate within the recommended airflow range for optimum oxygen transfer.
- Maintain adequate blower pressure for uniform bubble distribution.
- Periodically inspect the membrane for fouling, scaling, or wear in demanding applications.
- Clean or replace the membrane when required to maintain aeration efficiency.
⚙️ How It Works
Air supplied by the blower enters the diffuser through the threaded connection and passes beneath the EPDM membrane. As the air pressure increases, precision slits in the membrane open uniformly, releasing thousands of fine air bubbles into the wastewater.
These fine bubbles provide a large surface area for oxygen transfer, allowing aerobic microorganisms to efficiently break down organic contaminants. When the air supply stops, the membrane automatically seals, preventing wastewater and sludge from entering the diffuser.
