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.


INVENT Cyberpitch - Flash Mixer

The INVENT CYBERPITCH®- Mixer is particularly used for mixing applications where a high local energy intake is required. In the field of drinking water preparation it is used to thoroughly mix in flocculants and precipitant ideally followed by the well-known INVENT Hyperboloid mixers in the consecutive steps. Also in the wastewater treatment, the CYBERPITCH®- Mixer can be used, for instance for the suspension of activated carbon in a contact ...

INVENT 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 ...


Mixer Optimization Services

Mixers are developed and utilized for the most diverse of applications. However, the desired success is not always achieved. INVENT considers mixers and stirred vessels to be a complete unit and can help you to optimize your mixer application thanks to their experience and fluid mechanical simulation tools.

Computational Fluid Dynamics

Nowadays, it is primarily so-called CFD calculations that are mostly associated with fluid mechanical simulations. A usually more direct method is the construction of a true-to-scale model and a scale-up of the obtained results. These pieces of data can then be consulted in order to validate CFD calculations. Only in this manner can definitive results be obtained.


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.
