CYBERFLOW-Accelerator going west

The INVENT CYBERFLOW®-Accelerator going west… installed at a wwtp in Queretero State, Mexico. The horizontal flow generator for racetrack basins moves the wastewater horizontally in a circuit and at the same time prevents sedimentation of activated sludge. Product Page 

Efficient Wastewater Treatment in the Pulp and Paper Industry

The enormous demand for brown cardboard and paperboard driven by the increase in sales figures in online trade requires especially coordinated methods and equipment for wastewater treatment. With the HYPERCLASSIC®-Mixer/Aerator, a unique combination of mixing and aeration system, INVENT provides the solution for the demanding tasks of aerobic wastewater treatment. Press release

Water brings me joy

25 years ago, we wanted to conquer the world. So we did, by simply just doing. Now we have over 120 employees. This team makes INVENT unique. 
In our video we take a look behind the scenes:  

Innovative iFILT®-Diamond Filter for the retention of microplastics

State-of-the-art wastewater treatment plants equipped with the relevant filter technology are already able to filter out microplastics from the wastewater, thereby drastically reducing the release into the environment. The research project "Removal of Microplastics from the Water Cycle (OEMP)" employed the INVENT iFILT®-Diamond Filter for two years in an effort to retain microplastics - and the results were impressive.

Hyperboloid mixers stand out with their excellent durability and energy efficiency

The joint wastewater association Staufener Bucht, Germany, has placed its trust in the hyperboloid mixing technology of INVENT AG. After 21 years in operation, the association has made the decision to replace the 15 HYPERCLASSIC ® mixers of the second generation with even more energy efficient mixers of the seventh generation.

INVENT AG: 25 Years of High-Tech for Clean Water

INVENT is celebrating its 25th anniversary this year. The company based in Erlangen, Germany offers its customers groundbreaking technology for the purification of water and wastewater and is on course for growth worldwide. 

It started with the idea of developing sustainable, energy-efficient products for water purification and wastewater treatment viewed from an entirely different perspective, i.e. the fluid mechanics approach, and in doing so, setting new standards. With this idea, the experts revolving around Dr. Marcus Höfken - who at the start was the General Manager, and today is the CEO - took the step to venture into the economy, expanding with a clear purpose into the field of municipal and industrial water purification and wastewater treatment.

“Our huge commitment to manufacturing and utilizing high-performance products that contribute greatly to maintaining our water quality makes our company unique," explains Dr. Marcus Höfken. He continues to explain that Invent is the only company worldwide that offers a truly complete array of products – from agitators, mixing and aerating systems, membrane aeration systems, water filters, flow simulation systems to engineering services – for biological wastewater treatment and as such is able to offer its customers turnkey system solutions from a single source. Dr. Marcus Höfken proudly looks back at what has been achieved so far: “I am really pleased that we have managed to develop and build up a company that operates on an international scale on the basis of scientific research work, and that this company is today among the top 5 globally in its field”.

INVENT announces the arrival of the new iTURBO®-Aeration Blower

INVENT has designed an advanced turbo blower and implemented manufacturing techniques that allow every blower to be customised to the unique requirement of each wastewater treatment plant. This ensures the energy consumption and operating range is optimised for the specific process. The result is a dedicated machine operating at peak performance tailored for every application. This is a move away from standard machine size manufacture, where a one size fits all often results in under performance and/or unreliability.

Advanced fluid simulation for the water & process industry

High resolution, realistic, real time fluid simulation opens a whole new world of possibilities. THINK Fluid Dynamix® is a consulting and engineering service department that specializes in advanced numerical technologies, such as computational fluid dynamics and automated optimization.

Wastewater treatment in breweries – INVENT’s process engineering solutions

Wastewater coming from breweries is biologically and chemically heavily contaminated, the most important parameters being the biochemical oxygen requirement and sulfides that, when inadequately areated, can lead to olfactory problems (hydrogen sulfide). The federal government’s central wastewater processing agency stipulates strict maximum permissible values for the direct discharge of a brewery’s wastewater. Indirect discharge facilities are subject of different permissible values, varying partly depending on the specific communities. In any case, compliance with the permissible values is highly relevant for wastewater treatment plant operatorsin the vicinity of a brewery. Read press release
