Coarse bubble diffusers
Our clog-free coarse bubble diffusers mix and aerate wastewater with high concentrations of solids. They are the ideal choice for sludge storage tanks and activated sludge tanks with biofilm carriers.
Clog-free performance
Superior mixing and aeration
Solids concentrations up to 8%
Open bottom flushes solids
Independent air connections
Stainless steel construction
No maintenance
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 cross-flow 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.
Applications
- municipal treatment plants
- agri-food processing plants
- pulp and paper mills
- breweries and wineries
- dairies
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 cross-flow currents that effectively break down organic material and keep solids in suspension so they do not 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.
