INVENT made a major contribution by introducing hyperboloid mixing technology to the water and wastewater treatment market in the 1990s.
HYPERCLASSIC®-Mixer
Product Information
The HYPERCLASSIC®-Mixer is the optimum mixer for all suspending and homogenization tasks required for water and wastewater treatment.
The rotation of the hyperboloid-shaped agitator body close to the bottom generates high-speed and turbulence at the bottom of the basin. This reliably prevents the settling of sludge particles.
Eight transport ribs generate a three-dimensional main flow with a high circulation rate. This ensures excellent, uniform mixing.
Because of the low speeds, the energy input is low in shear force. Sludge flocculation is thus subjected mechanically to minimal stress loads.
Low speed at the water surface reliably prevents aerosol formation and oxygen transfer.
Efficient design and the use of rugged materials minimize operating and maintenance costs.

Applications of the INVENT HYPERCLASSIC®-Mixer
Denitrification
With denitrification, it is crucial that the entire tank content is homogenized and that oxygen entry on the surface is avoided. The HYPERCLASSIC®-Mixer is suitable for this, which generates a bottom flow directed radially outwards via transport ribs optimized in terms of flow mechanics. The particles are transported upwards along the pool wall. At the water surface, the flow velocity has reduced to such an extent that no oxygen is introduced.
Biological phosphate elimination
In biological phosphate removal, it is crucial to homogenize the entire tank contents while avoiding oxygen input at the surface.
The HYPERCLASSIC®-Mixer is well suited for this purpose, as it generates a radially outward-directed bottom flow via flow-optimized transport ribs. Particles are transported upward along the tank wall. At the water surface, the flow velocity has decreased to such an extent that no oxygen transfer occurs.
Degasing
During degassing, the entire tank contents are intensively mixed, effectively removing any gas bubbles that may be present. The HYPERCLASSIC®-Mixer ensures thorough and intensive mixing of the degassing tanks thanks to its high circulation rate.
Precipitation
Effective precipitation of dissolved impurities requires immediate and thorough mixing of the precipitant, along with sufficient contact time between the flocculant and colloids to promote the formation of microflocs. The HYPERCLASSIC®-Mixer meets these demands with its flow-optimized design and high circulation capacity.
Flocculation
Crucial for the success of the development of macroflocks is a gentle mixing with simultaneous complete circulation of the entire tank content and the flocculation aids within the dwell time.
The HYPERCLASSIC®-Mixer has low shear forces due to its hyperboloidal mixer body shape and low speeds and at the same time ensures complete mixing of the container. This leads to frequent particle interactions, which enables maximum floc growth.
Coagulation
In coagulation, it is crucial to mix flocculants quickly and effectively. This destabilizes colloidal systems and allows suspended particles to combine into larger, settleable flocs.
With its high circulation rate, the HYPERCLASSIC®-Mixer provides an optimal technical solution.
Mixing and Balancing
In certain cases, it is necessary to homogenize the wastewater before further treatment.
To achieve this, different wastewater flows from various sources are combined in a mixing and equalization tank to ensure a consistent supply to the downstream treatment stages.
Thanks to its high pumping capacity and outstanding mixing performance, the HYPERCLASSIC®-Mixer provides an ideal technical solution for such applications.
Neutralization
In neutralization, it is essential to quickly and effectively mix in an acid or a base. This ensures rapid adjustment of the pH level for the subsequent treatment stages.
With its high circulation performance, the HYPERCLASSIC® Mixer offers an optimal technical solution.
Sludge storage
As part of sludge treatment, sludge from primary or secondary clarification is collected and homogenized in tanks before further processing. Thanks to its bottom-mounted impeller, the HYPERCLASSIC®-Mixer is ideally suited for tanks with fluctuating water levels.
Trace substance elimination
For the removal of trace substances using activated carbon, the loaded carbon particles must be separated from the wastewater through flocculation. Successful formation of macroflocs requires gentle mixing to protect the flocs, along with complete circulation of the tank contents and flocculation aids within the retention time.
Adsorption
In operation, the HYPERCLASSIC®-Mixer generates low shear forces thanks to its hyperboloid shape, large impeller diameter, and low rotational speeds, while simultaneously ensuring complete mixing of the tank contents.
Suspension in packed bed processes
When so-called packing media are used in anoxic processes during wastewater treatment, mixers are required. During the growth phase, the packing media often float on the water surface and must be incorporated by the mixer.
The HYPERCLASSIC®-Mixer is ideally suited for this purpose due to its high mixing capacity and additional mixing elements designed to integrate the packing media.
Disinfection
For effective disinfection, it is essential to mix the disinfectant thoroughly with the wastewater to ensure maximum contact time between them. The HYPERCLASSIC®-Mixer provides the ideal technical solution with its high circulation capacity.
