  • HYPERCLASSIC Mixer evolution7

    INVENT made a significant contribution to the efficiency and cost-effectiveness of such plants by introducing the hyperboloid mixing technology to the market for water and wastewater treatment over 20 years ago.

    Since then, the hyperboloid mixing technology has been continuously developed and improved. Thousands of successful installations in municipal and industrial water and wastewater treatment plants world-wide impressively demonstrate that the hyperboloid mixing technology has already become the industrial standard in this field of application.

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

  • HYPERCLASSIC-Flocculation System

    The HYPERCLASSIC®– Flocculation System is based on the patented hyperboloid mixer, which outshines as a result of its minimum shear forces combined with excellent mixing and sedimentation-free properties.

    Given its relatively long yet gentle acceleration path along the agitator body, shear forces on the particle flocs are reduced.

    Dead zones are effectively avoided by distributing the outflow radially away from the agitator body, across the bottom and into the corners of the basin. This reliably keeps flocs from settling.

    Uniform mixing of the entire basin contents allows ensures that particles interact frequently, resulting in maximum floc growth.

    HYPERCLASSIC-Flocculation System

    The INVENT HYPERDIVE® - Mixer is a vertical mixer with a hyperboloid-shaped mixer body, installed close to the bottom, and a submersible drive. Contrary to other products, it was developed and designed especially for applications in the area of water and wastewater Treatment.

  • HYPERMIX Agitator

    Stratification in drinking water reservoirs represents a big risk. During the stratification process, different water layers with different temperatures occur. There is no fluid exchange between these layers which leads to longer dwell times for a part of the water and thus to algal formation, subsequent germination and/or uncontrolled chemical concentrations. All this can easily be prevented by the implementation of the INVENT HYPERMIX®- Agitator developed especially for complete volume movement.

  • iBC-MIX - Tote Tank Mixing

    IBCs (Intermediate Bulk Container), tote, or pallet tanks are often used for the transport and storage of bulk liquids, such as chemi¬cals, flocculants, coagulants, food and beverage ingredients, paint and coatings pre-products or final products, or other commodities. Many of these products or pre-products consist of more than one phase, and segregate if the suspension is not mixed continuously or at least before the liquid suspension or liquid/liquid mixture is withdrawn from the tank. For any of such applications the INVENT iBC Mix is an easy solution for container mixing.

    The INVENT iBC Mix is designed for the continuous operation in steel caged IBC tanks of va¬rious standard sizes and liquids of different composi¬tion, viscosity, and rheology. It consists of an AC drive unit, a docking traverse, the shaft and an impeller of application dependent design. The INVENT iBC Mix has a wide range of applications. It can be used for the continuous mixing of chemicals,...

  • CYBERFLOW Accelerator

    The INVENT CYBERFLOW®- Accelerator has been specially developed and optimised for the energy-efficient the generation of a horizontal flow in the recirculation basin for biological wastewater treatment. The overall fluid mechanics concept used here is revolutionary in comparison to conventional flow generators. This results in improvements in the level of efficiency of up to 30%, irrespective of the application. This is made possible by a holistic, fluid mechanics optimisation approach which considers not only the propeller design, but the entire machine in the interaction with the flow passage. This approach is based on the knowledge that themes which have so far been ignored, for example the

    • installation location
    • installation position
    • flow direction
    • incident flow
    • wake
    • design of the foot

    play an important role in addition to the propeller design for the overall level of efficiency of a horizontal flow a...

    CYBERPITCH  Flash Mixer

    One of the key-parameters for the overall energy efficiency of a biological wastewater treatment plant is the ability to produce a high amount of methane gas in the waste sludge digesters. The more gas can be delivered to the biogas motors, the more energy can be produced to run the various machinery compo¬nents on the plant. The amount of the gas production in a sludge digester depends on the quality of the sludge and the correct mixing, circulation, and homogenization of the waste sludge in the digester.

    INVENT’s fluid mechanical know-how, it’s vast experience in the field of mixing, combined with its pas¬sion for developing innovative products, has led to CYBERSLUDGE®, the INVENT Mixing System for sludge digesters.

  • HYPERCLASSIC Mixer/Aerator

    The INVENT HYPERCLASSIC®- Mixing and Aeration System was developed and optimized especially for demanding applications in municipal and industrial wastewater treatment plants. It provides efficient oxygen transfer and optimal mixing during the biological stage.

    In addition to the task of introducing oxygen, it also fulfils the important function of mixing and avoiding sedimentation. Due to the mechanical aeration method, the oxygen transfer performance is nearly as high in wastewater as it is in pure water. Even after many years, the aeration performance is not diminished. The system's pressure loss remains constantly low. The system can be installed simply and quickly, even in a filled tank.

  • Floating HYPERCLASSIC-Mixer/Aerator

    For the important task of mixing and aeration in aerated lagoon treatment plants the engineer or
    operator had only two options until today: He could either use surface aerators or floating membrane
    aerators. While the surface aerators usually do not provide economical oxygen transfer performance and
    insufficient mixing, the floating membrane aerators have to overaerate to provide sufficient mixing.

    With the HYPERCLASSIC®-Mixer/Aerator on a float INVENT makes its proven hyperboloid mixing and
    aeration technology available for the application in aerated lagoons for the very first time.

  • Floating EFLEX Membrane Aeration System

    E-FLEX®- FLOAT is the floating version of our proven E-FLEX®- Aeration System. It is mainly used for aerated wastewater ponds or lagoon tanks with plastic liner, earthen basins with natural sealing, natural ponds and lakes and all aerated tanks, in which the levelling of conventional bottom aerators is only possible with considerable effort due to the unevenness of the bottom.

    The E-FLEX®- FLOAT Aeration System is a so-called „chain aeration system" based on multiple aeration chains, which can move through the activated sludge tank at right angles to their longitudinal axis. One single „chain" consists of a floating air header, which simultaneously serves as a buoyancy body. Individual aeration modules are connected at regular intervals to this floating header via flexible downpipes.

  • DYNAMIX-Disk Filter

    High-tech for tertiary wastewater treatment

    The reuse of water directly after it has been treated in a wastewater treatment plant is increasingly gaining in importance. A fundamental part of tertiary wastewater treatment is the added filtration. It is the basis for further steps of conditioning towards water recycling, such as a fourth treatment stage, separation of microplastics, retention of phosphorus, or disinfection.

    The INVENT iFILT-diamond filter was constructed especially for the separation of solids from fluids as the next treatment phase after secondary sedimentation. It removes the smallest suspended solids that are still present in wastewater, for example

    - activated sludge flakes
    - precipitation flakes after phosphorus reduction
    - powdered activated carbon
    - microplastics

    In the area of industrial wastewater treatment the iFILT-diamond filter is applied in the following areas (examples):

    - general reuse of pr...
