With this system, INVENT offers a highly flexible and robust solution for fine-bubble aeration in waste water ponds or basins where floor mounting and leveling is not possible.
Floating HYPERCLASSIC® Mixing and Aeration System
Especially for the use of the HYPERCLASSIC®-Mixing and Aeration System in pond treatment systems, INVENT has developed a platform that allows the unique agitator to float smoothly and stably on the water surface.
Process air passes through the hollow shaft and hyperboloid-shaped agitator body. This way, near-bottom aeration is achieved without the need for additional installations in the pond.
Even previously unused sections of the pond can be accessed with the floating version of the HYPERCLASSIC®-Mixing and Aeration system. Compared to surface aerators, the degree of utilization of the given water volume is significantly higher. Plus, the dwell time is increased by the fluid optimized design of the evo7 Mixer.
With the slim design of the platform, installation near the pond is easy and fast. The complete system is then lifted into the pond, pulled to its operating location and connected.
To fix the raft in the desired position, INVENT offers customized weights with guy ropes.
Benefits at a glance:
• Agitation without aeration possible
• Fine-bubble aeration near the bottom of the pond
• Efficient use of the pond volume
• Intermittent operation possible
• Floating platform with safety guard rails
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 – an integrated air flow measurement for maximum control or coating options of the platform are possible.

Applications of the Floating 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.
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.
Aerobe 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.
