INVENT made a major contribution by introducing hyperboloid mixing technology to the water and wastewater treatment market in the 1990s.

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.

    HYPERCLASSIC®-Mixer evolution 7

    With the current version of the HYPERCLASSIC®-Mixer evolution 7, the seventh, completely revised and revolutionary improved version of the classic hyperboloid agitator is now available.

    Products and Team

    The wide range of INVENT products fulfills all process- and plant dependent requirements for biological wastewater treatment reliably and energy efficient.

    Applications of the INVENT HYPERDIVE®-Mixer


    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 speed has reduced to such an extent that no oxygen is introduced.


    For the destabilization of the colloidal state, a high energy input and a long contact time between the flocculant and the colloid are required for the formation of micro flocs. The CYBERPITCH®-Mixer combines these aspects with its flow-optimized agitator blade shape and its design for high speeds.


    Crucial for the success of the development of Markoflocking is a gentle agitation 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 agitator 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.


    The CYBERPITCH®-Mixer is suitable for quickly and efficiently stirring in the activated carbon and mixing it during the reaction time (adsorption) if a high local energy input is required. The HYPERCLASSIC®-Mixer is used for applications with low shear forces, as it ensures complete mixing that is much more gentle on the particles thanks to the lower speeds, a larger agitator diameter and the design of the agitator body close to the bottom.
