Coarse bubble diffusers
Eliminate costly and time-consuming maintenance with our clog-free coarse bubble diffusers. These solutions reliably mix and aerate wastewater with high concentrations of solids, making them ideal for sludge storage tanks and activated sludge tanks with biofilm carriers.
Superior mixing and aeration.
Ideal for solids concentrations up to 8%.
Open-bottom design flushes solids.
Independent air connections.
Stainless steel construction.
Enhanced fouling resistance.
Minimal parts replacements.
What is a coarse bubble diffuser?
A coarse bubble diffuser is a mixing and aeration solution for municipal and industrial wastewater treatment projects. It is ideally suited to the activated sludge processes used by MBBR and SBR systems.
Available in lengths up to 4.25 m, Ecoprocess coarse bubble diffusers (formerly known as AirOmega) reliably transfer oxygen and mix wastewater by generating powerful crossflow currents. Thanks to our unique open-bottom design, solids are automatically flushed away to give you clog-free performance you can trust in all conditions.
- municipal treatment plants
- agri-food processing plants
- pulp and paper mills
- breweries and wineries
How do our coarse bubble diffusers work?
A centralized air supply forces air through pipes fixed to the bottom of the basin. This air enters the rectangular chamber that houses each Ecoprocess coarse bubble diffuser, then exits the unit through rows of calibrated orifices.
The vertical power of diffused air generates crossflow currents that effectively break down organic material and keep solids in suspension so they don’t form unwanted sludge.
To ensure high performance, each diffuser uses our open-bottom design to constantly flush away solids. This simple but important feature prevents fouling and eliminates the need for diffuser maintenance.
