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.


TEX-FLEX - Aeration System

The TEX-FLEX -Aeration System has been specially developed and optimized for demanding applications in industrial and municipal wastewater treatment plants. For industrial applications in particular, the use of conventional membrane diffusrers is restricted or even impossible, or else they must be frequently replaced in order to guarantee trouble-free operation of the plant. In this situation, the TEX-FLEX- ...

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 ...


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 ...
