Floating HYPERCLASSIC®-Mixing and Aeration System conquers Swedish industrial plants

The innovative Floating HYPERCLASSIC®-Mixing and Aeration System gaining popularity in industrial plants across Sweden, particularly in lagoon wastewater treatment facilities operated by pulp and paper manufacturers. These facilities are specifically designed to address the challenges associated with wastewater treatment and require efficient aeration technologies.

In Sweden, lagoon wastewater treatment plants are widely utilized for treating wastewater from the pulp and paper industry. However, traditional aeration technologies such as surface aerators, membrane aerators, and submerged aerators often encounter issues such as underutilization of volume, poor circulation, and high maintenance requirements. The HYPERCLASSIC®-Mixing and Aeration System is the solution to these challenges by being mounted on a floating platform, enabling aeration close to the bottom and ensuring effective mixing of wastewater through high turbulence.

The adoption of the HYPERCLASSIC®-Mixing and Aeration System has resulted in significant improvements in treatment performance at wastewater treatment plants within the global process industry. Notable enhancements include increased mixed volume, extended mixing range, and improved sludge quality. Additionally, the system’s flexibility and robustness contribute to reduced maintenance costs.

One example involves the replacement of a membrane aeration system in a Swedish industrial wastewater treatment plant with a lagoon capacity of approximately 50,000 m3. By utilizing the HYPERCLASSIC®-Mixing and Aeration System, aeration performance increased by approximately 30% without the need for additional blowers. This led to reduced maintenance costs and overall more efficient wastewater treatment.

In another case, a Swedish industrial wastewater treatment plant replaced three surface aerators with just one HYPERCLASSIC®-Mixing and Aeration System in 2021 This resulted in consistent dissolved oxygen concentrations near the shore. Maintenance requirements decreased significantly, with only an oil change needed every two years. The system’s flexibility allows for adjustments in aeration capacity or switching to agitation mode without aeration to prevent sludge deposits on the lagoon floor.

In the north of Sweden, an industrial wastewater treatment plant retrofitted its lagoon with six mixing and aeration systems and two mixing systems to accommodate higher production volumes. Consequently, some surface and submersible aerators previously in use were decommissioned. The HYPERCLASSIC®-Mixing and Aeration System is mounted on a floating steel platform, with an optional maintenance platform for easy access during oil changes. Connected to a compressed air supply, the system does not require any other fixed or high-maintenance equipment in the tank. Installation on land and subsequent lifting into the lagoon are straightforward. Once secured in place and connected to the process air, the system can be put into operation.

The meticulously planned design facilitates straightforward installation on land and seamless lifting into the lagoon afterward, as illustrated. Lastly, the Floating HYPERCLASSIC®-Mixing and Aeration System is securely positioned as intended, connected to the process air, and put into operation.

INVENT‘s extensive expertise in wastewater treatment is evident in the successful deployment of the Floating HYPERCLASSIC®-Mixing and Aeration System. Engineers in Erlangen consistently develop comprehensive solutions tailored to meet specific needs. The production of these systems primarily utilizes regional materials and services. Since its inception in 2019, the floating mixing and aeration system has proven to be highly effective and is gaining popularity not only in Sweden but also in other regions.

CFD in the wastewater industry

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.

Conclusion

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.
