INVENT Stories from IFAT

IFAT is always an exciting challenge for INVENT – be it during preparation, realization, or on the days of the exhibition itself. Everyone at INVENT is enthusiastic to provide our visitors with a unique experience. In this interview series, INVENT employees share their own stories about IFAT. Today, it’s Anke Eisemann (Head of Marketing)’s turn.

Could you tell us more about yourself and your role at INVENT?

Before joining INVENT, I gained experience as a customer consultant in advertising agencies. This background prepared me well for my role in marketing at INVENT, where our operations are global and the tasks are diverse. As part of the marketing team, we handle various responsibilities, including organizing our participation in major trade shows like IFAT or WEFTEC in the USA, supporting our sales department and our partners, managing all advertising measures, and developing online and offline marketing strategies. We also act as the first contact for the trade press and maintain our websites and webshops. But above all, our biggest challenge is to maintain a comprehensive overview of everything!

What was your favourite moment at IFAT?

By chance, my first day at INVENT coincided with the IFAT, so INVENT and the IFAT have become inseparable in my mind. I was thrown into the full “exhibition experience” right from the start and met all my colleagues and sales partners at once. It was a memorable first day of work.

Isn’t a trade fair an incredible effort – even for you? Please tell us why it is still worth it.

Attending a trade show is an opportunity to establish real connections and make lasting impressions. It’s a chance to showcase products and services in a real-world setting and interact directly with interested individuals. That effort is worth it long term.

Will there be new innovations from INVENT to see this year?

Sometimes, innovation isn’t necessary to share something exciting. We’re spotlighting one of our trusted products, the CYBERFLOW®-Accelerator. This machine has been in the market for a few years and now, it will finally receive the attention it deserves with a unique video, and a modernized product presentation. We’ll debut the video at our IFAT trade fair booth. The premiere on Monday, May 13th at 2 p.m. will be an exciting moment which I don’t want to miss.

INVENT Stories from IFAT

IFAT is always an exciting challenge for INVENT – be it during preparation, realization, or on the days of the exhibition itself. Everyone at INVENT is enthusiastic to provide our visitors with a unique experience. In this interview series, INVENT employees share their own stories about IFAT. Today, Fabian Popp (Technical Sales) and Walter Steidl (Head of Technical Sales)’s turn.

Could you tell us more about yourselves and your roles at INVENT?

Fabian Popp: I’ve been working as a sales engineer at INVENT for five years, mainly looking after customers in Scandinavia and the Balkans. My preferred areas of expertise are MBBRs and lagoon applications.

Walter Steidl: I have been working at INVENT for over 25 years and have therefore been to IFAT countless times. I have been head of the Technical Sales department, which is responsible for preparing quotations, for over 10 years. Since my beginnings at INVENT, I have been the contact person for all questions relating to mixing tasks.

Walter, why do you believe an exhibition is so important?

Walter Steidl: I think exhibitions like IFAT offer everyone in the industry the opportunity to obtain comprehensive information about innovations. In addition to exhibiting new products, the focus is on exchanging ideas with existing and potential customers and sales partners. But it’s also always a kind of community that meets every two years to discuss water-related topics.

Fabian, why do you prefer an exhibition over the office?

Fabian Popp: Because you can interact directly with customers and understand their needs. At the trade fair, you can also see the latest trends and developments in the industry up close. The exhibition also has a lively atmosphere that boosts my creativity and motivation.

“Why are you asking me so much, all I need is a mixer…” – Please tell us what’s actually behind it.

Walter Steidl: That is simply our philosophy, to take a holistic approach to a task. We don’t just want to sell any product, but the one that best suits the customer’s requirements. To do this, we have to understand the entire process and weigh it up accordingly – always in dialog with the customer. Naturally, we have to ask a lot of questions in order to understand everything down to the last detail.

Fabian Popp: Our core competence lies in accepting and overcoming challenges. We deal intensively with every inquiry and strive to understand the process thoroughly. We select products that meet the highest standards for each specific case.

What are your favorite products at the INVENT booth and why?

Fabian Popp: Definitely the HYPERCLASSIC®-Mixing and Aeration System in a cage construction. It offers numerous advantages; it can be lifted out of a tank, has a large operating range and offers effective aeration performance with low wear. In addition, it can be equipped with various options to efficiently clean even highly contaminated wastewater.

Walter Steidl: My favorite product is also the HYPERCLASSIC®-Mixing and Aeration System in a cage construction. It simply has a few features that can only be found in this system. Our exhibit is on display in its original size and as a functional model. This gives us the opportunity to clearly explain the functionality to potential customers.


CYBERFLOW®-Accelerator at IFAT

By IFAT 2024

Revolutionary energy efficiency: CYBERFLOW®-Accelerator optimizes racetrack basins

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 up to 30% over traditional flow generators, regardless of the application.

In recirculation applications, horizontal flow generators for racetrack basins move the wastewater horizontally in a circuit and at the same time prevent sedimentation of activated sludge flocs. The CYBERFLOW®-Accelerator is the first horizontal mixer for racetrack basins which has been consistently designed and optimized based on fluid mechanical considerations. In this context, the interaction of the flow with the entire machine was considered. This approach focuses on optimizing all aspects for the design and application Including installation location and position, flow direction, upstream and downstream flow and design of the base construction. In addition to the propeller design, these items play an important role in the overall level of efficiency of a horizontal flow generator.

Flow direction

Conventional flow generators possess a direction of flow where the upstream flow is on the drive side. As a result, a turbulent and swirled flow hits the propeller and consequently results in high efficiency losses for the entire unit.

The high-performance propeller of the CYBERFLOW®-Accelerator is hit by a completly undisturbed upstream flow, thereby achieving much higher flow speeds with less energy input than conventional flow generators because efficiency losses due to disturbed upstream flows are avoided completely.

Vortex-free downstream flow

The integral fluid mechanical design of the CYBERFLOW®-Accelerator incorporates a so called “anti-vortex” base frame design which streamlines the flow and takes out the vortex induced by the propeller movement. This effect is supported by the additional “anti-vortex” fin on the back of the power train resulting in energy recovery by converting radial and tangential velocity components into actual axial flow.

With this intelligent design, it is possible for the first time to recover energy which is otherwise lost into energy dissipation. This design feature makes a considerable difference and severely contributes to the high energy efficiency of the entire machine.

INVENT Power Trim Technology®

More efficient than the indeed horizontally pump of conventional flow accelerators is to angle the drive shaft slightly so that the flow is aligned slightly upwards. This can greatly reduce friction – and therefore prevent energy-losses at the bottom of the tank. We call this alignment of the flow, which we chose depending on the application at hand, “INVENT Power Trim Technology®“ and this design optimization alone improves efficiency by up to 10 %.

Fluid-mechanically optimized base frame

In the design of the base frame, the CYBERFLOW®-Accelerator eliminates the use of standard rectangular tubes with unnecessarily high cw-values completely. Only rigid sheet metal structures with a small cross-section, minimized surface and small cw-values are used. This made it possible to create the base frame with the most streamlined design in the market.

Propeller design

The specific shape of the CYBERFLOW®-Accelerator propeller design was developed and optimized in the INVENT flow laboratories in Erlangen, Germany using state-of-research facilities, measuring technology and simulation methods specifically for use in activated sludge basins in wastewater treatment. This resulted in a smooth and efficient propeller geometry.

A further aim was to find a robust, durable, light and flexible, structural mechanical design. The result was a propeller structure made of glass- and carbon fibre-reinforced plastic in a sandwich design which can be used even in the most heavyduty municipal and industrial applications.

In result, the INVENT propeller design is superior to all conventional propeller designs in the market, irrespective of the number of blades used in the comparison propellers. INVENT uses an especially well-balanced two- and four-blade design.

Fluid mechanical laboratory

INVENT maintains a fully equipped fluid mechanical laboratory, pilot scale plants, and large scale test facilities at its headquarters in Erlangen in Germany. This enables INVENT to carry out all research and development work in-house with its own team of fluid mechanical specialists.

The CYBERFLOW®-Accelerator introduces a revolutionary overall concept, leading to efficiency improvements of up to 30%, depending on the individual case. After twelve successful years in the market, the CYBERFLOW®-Accelerator takes center stage at IFAT 2024 with an exclusive product video. The premiere of the brand-new video will take place on Monday, May 13th at 2 p.m. at the INVENT booth 327/426 in Hall A2. Come by and watch the video!”

INVENT iTURBO®-Blower at IFAT 2024

By IFAT 2024

High speed for clean water

Integral with any submerged aeration system is a pressurised supply air source to compress air for release below the water surface. The new INVENT iTURBO®-Blower has been designed specifically for this application.

INVENT has designed an advanced turbo blower and implemented state of the art manufacturing techniques that allow  blowers to be customised to the unique requirements of any wastewater treatment plant. This ensures the energy consumption and operating range is optimized for the specific process. The result is a dedicated machine operating at peak performance tailored for every application.

The iTURBO®-Blower is a radial compressor in either single or two stage configurations. The compressor is direct driven by a high-speed permanent magnet motor.

INVENT iTURBO®-Blowers are different! With over ten years of development and operating experience the iTURBO®-Blower incorporates “rigid” cartridge style air cushion bearings, not foils. The result is a dependable bearing without the complexity of active electronic control. The turbo impellers are optimized for the pressure and flow range required by any aeration system. Modelled with computational fluid dynamic (CFD) analysis in addition to test tuning to achieve peak efficiency.

Motor cooling is accomplished with a proprietary “2 pass” pressurised system for maximum heat transfer. As the system is independent of the process air, the blower can be used in extreme environments where ambient temperatures exceed 50° C.

The iTURBO®-Blower is an integrated blower package, using Siemens or Rockwell Industrial PLC controllers and HMI panels. All measurement sensors required for the safe and reliable operation of the blower are included within the package. The blower constantly monitors air flow, pressure, and temperatures within the package. A communications connection to the blower allows all operating and diagnostic information such as power consumption, speed, and operating hours to be transferred to the plant SCADA or DCS systems.

The acoustic enclosure is robust and durable. INVENT have standardised on heavy section zinc anneal sheeting powered coated with 100um heat hardened surface protection. Fasteners, fixings, and hinges on the blower enclosure are SS 316 stainless steel, the reason, to ensure all components have maximum life expectancy as the working environments are usually very harsh.

The iTURBO®-Blowers are available in a range from 22kW to 400kW, discharge pressure capability to 150 kPa.

Don’t miss the opportunity to experience technology up close and be impressed by the powerful performance of the iTURBO®-Blower! Visit our booth at this year´s IFAT in Munich,  booth number 327/426 in Hall A2, to experience the innovative iTURBO®-Blower firsthand.
