Fine Bubble Disc Diffuser

Fine Bubble Disc Diffusers are commonly used in STPs and ETPs where high oxygen transfer efficiency and uniform aeration coverage are required. Their disc-shaped design allows even air distribution across large tank floors, making them ideal for activated sludge processes, MBBR systems, and equalization tanks. By producing fine, evenly distributed bubbles, disc diffusers improve oxygen dissolution and enhance biological treatment efficiency. Compared to surface or coarse aeration systems, they significantly reduce blower energy consumption. This makes them suitable for continuous operation in municipal and industrial wastewater treatment plants where energy efficiency and process stability are critical.

Membrane MOC & Typical Use Case:
• EPDM: Best suited for municipal sewage and domestic wastewater with stable pH and temperature conditions
• Silicone: Recommended for industrial effluents containing oils, solvents, or higher operating temperatures

AIRFIN Quality:
AIRFIN Fine Bubble Disc Diffusers are manufactured using high-quality membranes and robust support plates to ensure uniform airflow and long operational life. Precision laser or molded perforations provide consistent bubble size and low pressure drop, resulting in reduced energy demand from blowers. The diffuser design minimizes clogging and allows easy installation and maintenance. Each diffuser undergoes strict quality checks to ensure leak-proof sealing and dimensional accuracy. Built to perform in demanding wastewater environments, AIRFIN disc diffusers deliver reliable oxygen transfer efficiency with stable performance over long operating cycles.

Uniform aeration, higher efficiency, lower energy cost.
