Goals and Vision

With our team of excellent and highly motivated employees, we concentrate on our core objectives of developing and offering our customers innovative, energy-saving and at the same time robust, safe and cost-effective products.

We are convinced that this strategy will enable us to fulfill our vision of being the world market leader in the field of mixing and aeration.


The growing pollution of our environment is a problem which concerns all of us. For years water pollution, in particular, has continued to grow in threatening proportions. Water is turning into a more and more limited resource. As a consequence, forward-looking technologies are desperately needed for water and wastewater treatment.

With great commitment INVENT is dedicated to the development and implementation of such technologies, thus creating powerful products which contribute greatly to the preservation of the water quality of our groundwater, rivers and lakes.

The protection, the preservation and, where necessary, the restoration of our environment will remain one of the most important tasks of our society in the future.

INVENT takes on responsibility in this field, with innovative environmental and process engineering.


INVENT was founded in the mid-1980s by a group of fluid mechanics experts, as a spin-off from the department of Fluid Mechanics at the Friedrich-Alexander University in Erlangen-Nuremberg.

INVENT’s involvement in the environmental field began in 1990 with the launch of its hyperboloid mixer technology for applications in water and wastewater treatment.

INVENT Umwelt- und Verfahrenstechnik AG in its current organisation originated in 1995 as a result of a management buy-out. In 2003, it became a stock-holding company (AG). Since 2004, INVENT has had a presence in the USA with a subsidiary company.

INVENT is represented in all of the world’s most important markets, by commercial representatives, licensed partners, and its own branch offices.


Hyperdive - Mixing and Aeration System

The INVENT HYPERDIVE®- 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 ...

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 ...


Oxygen Transfer Testing

We have decade-long experience when it comes to executing oxygen transfer rate measurements in accordance with DWA or ASCE guidelines in the laboratory, on a large-scale and on large-scale installations. We would like to share this experience with you and offer such measurements as a service. A fully-equipped test facility and a tank with a diameter of 10.24 m and a maximum filling height of 8 m is available for 'shop tests' at our site in Erlangen, ...

Velocity Profile Measurements

Bottom flow velocity measurements are occasionally required for acceptance and as proof of performance of the mixers. The correct execution of such measurements in complex, three-dimensional flows requires expert knowledge of fluid mechanics as well as experience when it comes to preparation, execution and assessment. We exclusively use ultrasound Doppler measurement devices for the measurement itself. These devices simultaneously collect all three ...


ANAwin - Static Dimensioning Of Biological Wastewater Treatment Plants

Our reliable classic ANAwin supports your static dimensioning of biological wastewater treatment plants. This important, yet time-consuming task will be noticeably simplified and accelerated with the help of ANAwin. ANAwin works on the basis of the generally acclaimed DWA rules and regulations.


Training & Education

Continuous training and education of our employees, our sales partners and clients is a core commitment of INVENT. Beside our internal development program we offer to our clients in house seminars about. Fundamentals of mixing technology. Fundamentals of mass transfer and aeration technology. Oxygen transfer measurements. and hands on trainings on Mixer and mixer / aerator installation and start-up. Aeration system installation and start-up.
