OKI aerator mixer
Combining aeration and mixing
The submersible OKI aerator mixer is a heavy-duty, non-clogging, gentle mixing unit which can operate both as an aerator and as a mixer for wastewater and water treatment in municipal and industrial plants. It is used for sludge stabilization in SBR, MBR, and MBBR processes.
- Liftable and selfstanding, making it easy to change of the plant configuration—no need to empty the tank
- Suitable for all usual tank depths, especially deep tanks which no longer require air cooling
- Designed for non-clogging operation
- Suitable for both continuous and intermittent process operation
- Can run as an aerator and/or mixer according to process requirements
- High Standard Oxygen Transfer Rate (SOTR) and Standard Aeration Efficiency (SAE) values
- Activated sludge basins and Sequence Batch Reactors (SBR), Membrane Bio Reactors (MBR), and Moving Bed Bio Reactors (MBBR), providing aeration and mixing in a single unit for degrading the biomass
- Mixing and equalization basins, providing uniform wastewater loading to downstream processes and eliminating odors
- Sludge storage and stabilization, providing odor control as well as oxidation of sludge
- Flotation of oil and grease
- Additional aeration
- Quick and easy installation and maintenance
- High efficiency hydraulics
- Heavy-duty submersible gearmotor
- Heavy-duty mechanical labyrinth shaft seal

Case studies
Aerator mixer upgrades industrial wastewater treatment
The mill has its own biological wastewater treatment plant with a total capacity of 350’000 population equivalent. Once treated, the water is recycled in the mill or restored to the natural environment. The WWTP has been modernized regularly during the past years
Aeration system improves wastewater treatment in a frozen vegetables plant
The Ardo frozen vegetables factory in Koolskamp, Belgium, has its own wastewater treatment plant with an anaerobic digester, aerated biological basins and a tertiary filtration stage with UF and RO membranes. Most of the treated water can be reused on site. To further improve the efficiency of the WWTP, Ardo decided to progressively replace the old surface aerators in the biological basins by optimally-adapted equipment.
