CFD Simulations in the Wastewater Industry: Bridging Theory and Reality

The realm of fluid mechanics is an intricate web of physics, mathematical models, and real-world applications. In the wastewater industry, understanding these fluid dynamics is not just a scientific exercise but a necessity. Enter Computational Fluid Dynamics (CFD) – a crucial tool that has revolutionized the way we approach and solve real-world fluid mechanics problems.

The Origins of INVENT’s CFD Journey

In the 1990s, the foundation of INVENT by Dr.-Ing. Marcus Höfken signaled the rigorous application of fluid mechanics in wastewater treatment. Having its roots at the Department of Fluid Mechanics of the University Erlangen-Nürnberg under the leadership of Professor Dr. Franz Durst, INVENT was borne out of a genuine passion for fluid mechanics, combined with a rigorous scientific approach.
From its early days, INVENT recognized the potential of CFD simulations, leveraging its capabilities in collaborations with academic institutions. Recognizing its immense potential, the company soon established an in-house CFD department, which quickly evolved to cater exclusively to the intricacies of water and wastewater treatment. From modeling mixers with detailed CAD geometry to multiphase simulations for aerated tanks, INVENT was at the forefront, challenging conventions and elevating standards.

CFD in Wastewater Treatment: Bridging Theoretical and Practical Gaps
But what is CFD? At its core, Computational Fluid Dynamics (CFD) is the use of applied mathematics, physics, and computational software to model and visualize fluid flows. This becomes indispensable in wastewater treatment.

There are many examples: Aerated tanks, for instance, demand multiphase simulations. Such simulations can help predict the Standard Oxygen Transfer Rate (SOTR), a crucial metric in biological wastewater treatment. Additionally, understanding the movement and behavior of suspended solids and activated sludge is vital. CFD helps in modeling these phenomena, providing insights into particle trajectories, settling patterns, and more.

Furthermore, in stirred tank reactors or in pump stations, the effects at the water’s surface, often marked by turbulent behaviors and leading to vortex formation, can be complex. CFD simulations, by modeling these surface effects, assist engineers in designing and optimizing treatment processes.
As we delve further into the realm of wastewater treatment modeling, the emphasis on particular features and techniques becomes indispensable. Here’s why:

1. Rotating Turbomachinery: One cannot underestimate the importance of precisely modeling rotating turbomachinery. In wastewater treatment plants, these machines play pivotal roles, ensuring efficient flow circulation and solids suspension. Accurate modeling ensures reliable representation of real pumping operation

2. Multiphase Simulation for Aeration: Aeration is critical for the biological oxidation processes in the biological treatment of wastewater. Understanding intricate physics, such as bubble dynamics, is essential. Factors like bubble breakup, their eventual coalescence, and mass transfer are key to reliably predict oxygen transfer rate.

3. Sludge Floc Transport: Sludge flocs, or aggregated particles also require further investigation and careful modeling. When considering the multiphase simulations for their transport, a complex factor comes into play: rheology. As the concentration of these flocs increases, the fluid’s behavior deviates from the Newtonian ideal, adopting characteristics of non-Newtonian fluids. This alteration in fluid behavior, coupled with flocculation effects—where particles come together to form larger aggregates—adds layers of complexity to the modeling process.

However, a significant challenge remains. The behavior of biological compounds in wastewater cannot be explicitly modeled within fluid mechanical equations. This is where the role of a numerical-empirical approach becomes essential. By combine theory with empirical data, we ensure accurate results rooted in real-world observations and validations. The potential applications of CFD in this arena are vast, spanning screenings, hydraulic dynamics, water distribution, and beyond. Think of anoxic tanks, clarifiers, oxidation ditches, anaerobic digesters—CFD has them all covered.

Tools and Collaboration

INVENT is always up to date when it comes to CFD technology. The M-STAR software, with its Lattice-Boltzmann approach for solving Navier-Stokes equations, offers advanced turbulence modeling techniques such as large Eddy Simulation. Powered by GPUs, it permits time-accurate dynamic simulations, providing an unparalleled insight into turbulent phenomena.
Turbulence, after all, is pivotal for mixing. The more accurately turbulence is modeled, the better the predictions related to mixing, a cornerstone in wastewater treatment processes.
Yet, the true strength of INVENT’s CFD department lies not just in its superior software and hardware tools but in its persistent endeavor for numerical validation. By continually comparing simulation results with experimental data, either in collaboration with academic institutions or through onsite experiments at wastewater plants, INVENT ensures the highest fidelity in its CFD simulations.
At the end: the best CFD is much more than a simulation, is also continuous experimental validations and calibration using a numerical-empirical approach.


In a world where precision matters, the use of CFD in wastewater treatment is not a luxury but a necessity. As the industry demands more sustainable and efficient solutions, the bridge between theoretical simulations and experimental validations will be even more vital. INVENT will continue to follow this path and simulate the complex waters in the wastewater industry.

Aerobic Digestion

By Press Release

A Strategy for Optimizing Aerobic Digestion: a Cyclical Process

A common misconception for aerobic digestion is that the process must be aerated 100% of the retention time. In redefining this outlook, it has been found that cycling between mixing and mixing while aerating proves to be more effective and energy efficient. By having the ability to turn the air off and on, the system creates aerobic and anoxic phases allowing for further nutrient reduction, improved dewaterability, and increased volatile sludge destruction.

This supports endogenous respiration and nitrification. Many different technologies exist for aerobic digestion, and often multiple types of equipment must be combined to achieve the cyclical process. Fortunately, there are systems that can perform decoupled mixing and aerating with only one device.

Aerobic treatment for pulp and paper industry

By General, Press Release, Project Report

Energy-efficient and proven: Mixing and aeration system for aerobic treatment in the paper industry

INVENT uses the example of a large manufacturer of paper and cardboard products for the pulp and paper industry to show why they are the ideal solution for wastewater treatment in this industry.

Some industries are plagued by particularly high energy and water consumption and therefore aim to reduce both sustainably. This is particularly true for the pulp and paper industry. Water treatment plays an essential role here, with INVENT Umwelt- und Verfahrenstechnik AG providing the best suited products.

An excellent example of the practical use of INVENT technology in paper wastewater can be found in the north of Germany, more precisely in Varel in the district of Friesland. The Papier- und Kartonfabrik Varel (paper mill), located on the outskirts of the small town, employs around 600 people on its site. It is not only a major regional employer but also one of the largest production sites in the German pulp and paper industry with a production capacity of around 925,000 tonnes.

The mill has a proud history stretching back 84 years. It mainly produces classic raw materials for the packaging industry and has been progressively modernized and expanded over the decades. As early as 1976, the company was one of the first paper mills in Germany to install a biological wastewater treatment plant. As part of the company’s growth, the plant was expanded to a two-step treatment plant in 1994.

The next expansions – in which INVENT technology came into action for the first time – took place from 2012 through 2014. HYPERCLASSIC®-Mixing and Aeration Systems were installed in stainless steel cages for aerobic wastewater treatment. One advantage of this cage solution is that it can be removed for installation and maintenance and put back in place, even in a filled tank.

The HYPERCLASSIC®-Mixing and Aeration System uniquely combines the characteristics of a mixer with those of an aerator, offering very flexible areas of operation and application. Firstly, it provides sufficient oxygen to the activated sludge during the aerobic process to break down the organic load. Secondly, the aeration tank is mixed homogeneously so that both the heavy activated sludge and small particles are kept in suspension.

Due to the energy-efficient operation, high quality and durability of the components the HYPERCLASSIC®-Mixing and Aeration System has made a name for itself as the industry standard in the aerobic treatment of paper wastewater in recent decades.

When the operators of the Papier-und Kartonfabrik Varel decided to invest 280 million euros in the production site in 2019, this also entailed a significant expansion of the wastewater treatment plant – and thus an order over another 13 of the trusted HYPERCLASSIC®-Mixing and Aeration Systems with a cage from Erlangen, Germany.

HYPERCLASSIC®-Mixing and Aeration System in the Pulp and Paper Industry

Providing clean water in Qatar

HYPERCLASSIC® systems provide clean water in Qatar

While star athletes are running on the soccer fields of Qatar, things are also running smoothly at the country’s largest wastewater treatment – thanks to the reliable hyperboloid mixing and aeration systems from INVENT.

The desert is alive! Wherever animals and people settle in the driest regions of our planet, water plays a vital role. The fact that some countries experience an economic boom despite the desert climate comes down to other causes, such as natural resources like oil and gas.

The resources that bubble up each day make dreams come true, build ultramodern cities with trading centers and tourism infrastructure, and even create living spaces in the desert for millions of people. Now more than ever, Qatar is in the public eye as the host of the 2022 FIFA World Cup.

The capital of Doha and the neighboring city of Al Rayyān in particular is right now playing host to sports-loving businesspeople, media representatives, and private individuals from all over the world. More than one-third of the 2.8 million inhabitants of the desert state live in the city of Doha. Residents and guests need food and in particular water for drinking and domestic use. This is a challenge in the dry, hot climate of the Persian Gulf, and every drop of freshwater is precious.

The city planners are prepared for this. The vast majority of the freshwater is sourced from seawater desalination plants. This is then pumped into the water circulation system and used for human consumption or agriculture. The water and wastewater treatment plants are indispensable parts of this system in this and other modern cities.

The largest in the country is currently the Doha West wastewater treatment plant. Since it was put into operation in 2009, the plant has been expanded several times and is now able to treat an average of 280,000 cubic meters of water each day. Slightly more than 50 percent of the treated wastewater is used for agriculture and around 40 percent is used to water green spaces in the city. The rest is fed into the ground to raise the groundwater level.

To ensure that the plant works smoothly, the client chose technology from Germany – from INVENT, to be precise. No fewer than 48 HYPERCLASSIC®-Mixing and Aeration Systems and 24 HYPERCLASSIC®-Mixers reliably perform their duties in various tanks at the plant each day.

In this way, INVENT technology is contributing to Doha not only being a modern city, but also a green one in which residents and guests can enjoy spending time outdoors and where thriving agriculture is possible nearby. Once the World Cup is over and the next large event is being planned, the HYPERCLASSIC® systems will continue to turn—the final whistle won’t be blown on them any time soon.
