Coarse Bubble Disc Diffuser

Coarse Bubble Disc Diffusers are used in wastewater treatment systems where strong mixing and agitation are required rather than high oxygen transfer efficiency. They are commonly installed in equalization tanks, grit chambers, pre-aeration tanks, and sludge holding tanks to keep solids in suspension and prevent settling. The large bubble formation creates high turbulence, which helps in breaking stratification and ensuring uniform mixing across the tank. Due to their open structure and robust membrane design, coarse bubble disc diffusers perform reliably in high-solid, high-fouling, and variable operating conditions typically found in municipal and industrial applications.

Membrane MOC & Typical Use Case:
• Silicone: Suitable for industrial effluents with higher temperatures, oil content, or chemical exposure where membrane flexibility and durability are critical
• EPDM: Ideal for municipal sewage and general wastewater applications with stable operating conditions and long continuous operation

AIRFIN Coarse Bubble Disc Diffusers are manufactured using high-quality silicone and EPDM membranes mounted on a sturdy diffuser base to ensure consistent air release and long service life. The membrane materials are selected to provide excellent tear resistance, chemical compatibility, and resistance to fouling. The diffuser design allows reliable air flow with minimal clogging and low maintenance. Each unit is produced under strict quality control to ensure uniform performance, structural integrity, and dependable operation in demanding wastewater treatment environments.

Strong mixing, dependable performance, built for tough conditions.
