INVENT made a major contribution by introducing hyperboloid mixing technology to the water and wastewater treatment market in the 1990s.
HYPERDIVE®-Mixer
Product Information
The HYPERDIVE®-Mixer is the optimum mixer for all suspending and homogenization tasks required for water and wastewater treatment, especially in very deep basins.
With its hyperboloid mixing system close to the bottom, its fluid mechanical performance characteristics are identical to those of the HYPERCLASSIC®-Mixer.
• High speeds and turbulence on the bottom of the basin
• Prevents settlement of sludge particles
• Three-dimensional main flow with a high circulation rate
• Sludge flocculation is mechanically subjected to minimal stress loads
With a compact, three-legged base, the mixer is ready for operation immediately after being lifted into place – even in filled basins – and connected.
As only well-known drive manufacturers are chosen, no extensive maintenance work is required.

Applications of the INVENT HYPERDIVE®-Mixer
Denitrification
With denitrification, it is crucial that the entire tank content is homogenized and that oxygen entry on the surface is avoided. The HYPERDIVE®-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 speed 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 HYPERDIVE®-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 HYPERDIVE®-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 HYPERDIVE®-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 HYPERDIVE®-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.
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 HYPERDIVE®-Mixer provides an ideal technical solution for such applications.
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 HYPERDIVE®-Mixer is ideally suited for tanks with fluctuating water levels.
Adsorption
In operation, the HYPERDIVE®-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.
