With this system, INVENT presents a highly flexible and rugged solution for fine-bubble aeration in municipal and industrial wastewater. Especially in difficult operating conditions, the exceptional properties of this system become increasingly valuable.
HYPERCLASSIC®-Mixing and Aeration System
Product Information
The HYPERCLASSIC®-Mixing and Aeration System was introduced in numerous process stages of municipal and industrial wastewater treatment plants over 25 years ago.
Uniquely, it combines the features of an agitator with those of an aerator, offering an extremely flexible range of operation and use:
- Agitation without aeration
- Fine bubble aeration with simultaneous homogeneous and deposit-free mixing
- Intermittent operation (e.g. SBR process, MAB)
The sophisticated design, the rugged construction and the mechanical aeration principle make this agitation and aeration system very versatile. As such, INVENT offers a reliable and variable solution for complex problems:
- High oxygen supply capacity even in difficult media (high TS, surface-active substances)
- No increase in pressure drop during operation in contrast to membrane aeration
- No aerosol formation
- Deposits are avoided in all operating stages
- Design in lift-out version available
- Materials are matched to operating conditions (temperature, pH, salinity, precipitation, etc.)
The HYPERCLASSIC®-Mixing and Aeration System is tailored to your requirements on a case-by-case basis and can be supplied in a number of versions – for installation on a bridge/tank cover, lift-out, submerged or floating.

Applications of the INVENT HYPERCLASSIC®-Mixing and Aeration System
Aeration in packed bed processes MBBR
The mass transfer processes in packed reactors are not determined by the size of the air bubbles, but rather by the nature and volume fraction of growth bodies and their specific surface area and wettability.
BOD or COD degradation
Highly efficient supply of oxygen to the microorganisms for BOD and nitrogen elimination.
The agitation and gassing system acts as a permanent aeration system for biological carbon degradation in aeration tanks. We can react flexibly to fluctuations in freight. The simultaneous circulation by the agitator ensures a homogeneous and deposit-free mixing even with low air supply in the activated sludge tank.
Fakultative aeration
In nitrification stages, the stirring and aeration system serves as a permanent aerator. If (seasonal) process changes in the activated sludge tank require a temporary changeover from nitrification to denitrification (swing zone), it is possible to run in pure agitation mode without aeration. A change between operation with ventilation and without ventilation is possible at any time.
SBR (Sequencing Batch Reactor)
In the SBR process, several cycles with different process phases are usually run through each day. Important boundary conditions for a well-functioning overall process include a rapid change between phases with oxygen supply and pure stirring operation, homogeneous mixing and flexible oxygen supply capacity with a wide working range.
In addition to the above boundary conditions, the stirring and gassing system offers other advantages in the SBR process:
In the case of strong seasonal freight fluctuations (food processing, tourism, etc.), a temporary shutdown is possible without any loss of quality of the components or functionality.
Simple installation without complex installations in the tank – With the liftable variant, maintenance can be carried out without emptying the tank.
Aerobic sludge stabilization
Activated sludge with a high dry matter content forms a viscous, pseudoplastic medium. Due to the shear-thinning effect of the agitator in aeration mode, there is a significantly better oxygen supply to the agitator and aeration system compared to membrane aerators. In addition, problems such as clogging of membranes, pressure increases and material aging due to high temperatures in the agitation and aeration system no longer play a role.
Pure oxygen aeration
The gassing or oxygen supply in the process can be carried out using the stirring and gassing system with atmospheric oxygen or pure oxygen.
Membrane Bioreactor (MBR)
Highly efficient supply of oxygen to the microorganisms for BOD and nitrogen elimination Continuous cleaning of the membrane surface to limit the cover layer thickness.
