INVENT Umwelt- und Verfahrenstechnik AG
About us
INVENT at a glance
Business activities began in 1990 when the Hyperboloid-Mixing Technology was introduced into the German and Swiss market. In 1995 INVENT Umwelt- und Verfahrenstechnik GmbH & Co. KG was founded. Due to the dynamic growth and international business activities, INVENT converted into a corporation in 2003.
Focus is centered on the supply of mechanical components for water and wastewater treatment, the development of process concepts and the delivery of complete plants.
The INVENT headquarter is located in Erlangen, Germany. Sales Offices in the US, Australia, UAE and Italy cater to the local markets. We reach our clients via approximately 60 sales agents, authorized dealers and licensees. You can find the corresponding sales partner for your region at

Products
INVENT HYPERCLASSIC®-Mixer
The INVENT HYPERCLASSIC®-Mixer is a vertical shaft mixer with a hyperboloid-shaped mixer-body installed close to the bottom and a dry-mounted drive. The rotation of the mixer body close to the bottom generates high-speed and turbulence at the bottom of the basin. This reliably prevents the settling of sludge particles. Its efficient design and the use of rugged materials minimizes operating and maintenance costs. The HYPERCLASSIC®-Mixer is the optimum mixer for all suspending and homogenization tasks required for applications in the area of water and wastewater treatment.
INVENT iTURBO®-Blower
The iTURBO®-Blower is a centrifugal compressor with individually optimized precision rotating bodies. An intelligent operating concept with multiple machines enables the setting of optimum operating points to achieve maximum efficiency. Customer-specific pressure stages achieve the peak efficiency at the operating points that are most frequently approached based on the aeration strategy. This contributes to a significant reduction in energy consumption. The iTURBO®-Blower is driven by a high-speed PMSM (permanent magnet synchronous motor) with frictionless high-performance air bearings. The motor operates with an integrated frequency converter with an efficiency level > 96%. Not only does it drive the motor, but it also monitors the torque, power, and speed supplied to the motor, for reliable, low-maintenance operation. The compact and lightweight design ensures quick and easy installation.
INVENT HYPERCLASSIC®-Mixing and Aeration System
The HYPERCLASSIC®-Mixing and Aeration System was introduced in numerous process stages of municipal and industrial wastewater treatment plants over 25 years ago. Uniquely, it combines the features of an agitator with those of an aerator, offering an extremely flexible range of operation and use: Agitation without aeration Fine bubble aeration with simultaneous homogeneous and deposit-free mixing Intermittent operation (e.g. SBR process, MAB) The sophisticated design, the rugged construction and the mechanical aeration principle make this agitation and aeration system very versatile. As such, INVENT offers a reliable and variable solution for complex problems: High oxygen supply capacity even in difficult media (high TS, surface-active substances) No increase in pressure drop during operation in contrast to membrane aeration No aerosol formation Deposits are avoided in all operating stages Design in lift-out version available Materials are matched to operating conditions (temperature, pH, salinity, precipitation, etc.) The HYPERCLASSIC®-Mixing and Aeration System is tailored to your requirements on a case-by-case basis and can be supplied in a number of versions – for installation on a bridge/tank cover, lift-out, submerged or floating.
INVENT CYBERFLOW®-Accelerator
The CYBERFLOW®-Accelerator is a revolutionary advancement over conventional flow generators. It has been specially developed and optimized for the most energy efficient generation of horizontal flows in applications such as biological wastewater circulation in donut, racetrack or carrousel type basins. Extensive research and development have led to efficiency improvements of traditional flow generators, regardless of the application. Optimization approach: This is made possible by a holistic, fluid mechanical optimization approach, which considers not only on the propeller design, but the interaction of the flow with the entire machine.
INVENT Aeration Technology
Wastewater treatment plants are the largest municipal energy consumers, with a large percentage of the energy within a plant being used to generate the compressed air for the aeration system of the activated sludge plant. Consequently, this is where there is the greatest potential for optimization within the plant as a whole. INVENT has specialized in this very topic and, with a broad portfolio of aerators, is able to offer an optimized solution for all embodiments of the activated sludge process. Adding an innovative control concept and the iTURBO®-Blower to our product range enables us to implement highly efficient complete systems by taking a holistic approach.
