Challenging, customer-specific mixing technology solutions can be numerically simulated as early as during the planning phase, and the results analyzed. This means increased design confidence, high-quality solutions and, as a result, reduced project durations and costs. Our experts from THINK Fluid Dynamix® are specialists in the application of numerical techniques such as flow simulation in real time and artificial intelligence methods for automated optimization. This enables processes, such as stirring and homogenization, to be analyzed more accurately under consideration of all applicable process parameters, and complex tasks to be processed far more efficiently. These methods set entirely new standards in terms of design reliability and efficiency. Allow us to contribute to your success!

For over 50 years, Geppert Ruhrtechnik has stood for quality and reliability in agitator construction. We develop, manufacture, and distribute innovative agitators for all applications in the materials processing industries, such as the chemical, pharmaceutical, biotechnology, and food industries, as well as in water and wastewater treatment. Our many years of experience make us the perfect partner for both standard and special applications. When selecting and designing our agitators, we draw on our many years of experience, internal databases, and state-of-the-art tools (such as FEM, Finite Element Method, and CFD, Computational Fluid Dynamics), as well as our own fluid mechanical laboratories. This means we always provide you with the optimal solution. In addition to our agitators, we manufacture suitable containers and stands for stand-alone, wall mounted, and mobile designs. We can implement these in your plants, taking into account any its specific requirements.

In the manufacture of semiconductors, agitators are mainly used in conditioning of polishing and cutting suspensions, etchants and other auxiliary chemicals, cleaning solutions, or in chemicals recycling. Requirements placed on stirring systems are extremely demanding. Almost always, clean room conditions prevail, meaning that drives and seals must be designed with no abrasion or leakage. Parts that come into contact with the medium, such as the shaft and stirring element, often have to be produced with metalfree surfaces due to the aggressiveness of the media and the purity requirements. Also in this area, Geppert Ruhrtechnik can look back on a very successful history. All well-known chip manufacturers belong to our client base, as well as the manufacturers of the specialty chemicals used in this field. In addition, our agitators are used in broad solar cell production areas.

Despite the increasing level of digitalization, an ever-increasing demand for paper and pulp products can be observed. However, a shift is taking place from print paper qualities to packaging paper and cardboard. The wide range of paper products requires a variety of production processes. These include mechanical and chemical processes which, depending on the form and variant, produce different pulp qualities. Stirring and mixing are essential unit processes in all types of paper and pulp production. Mixing tasks range from liquid/liquid or gas/solid/liquid mixtures, through mixing of complex liquids, and include mixing of chemically reactive components. Improving and optimizing mixing processes in the paper and pulp industry can lead to end product improvements; such as increased strength, improved luster, or significant energy or chemical savings.

In the treatment of drinking water, whether done conventionally or via seawater desalination, agitators are used for rapid mix, precipitation and flocculation processes. Precipitation and flocculation processes require low shear, slow-running agitators. For pH adjustments and rapid mixing faster running agitators that can blend reactor content in a flash are required. Wastewater treatment also requires a multitude of application options for agitators. In anaerobic and anoxic tanks for nitrogen removal, slow-running agitators are used to suspend and homogenize activated sludge flocs. In aeration tanks, mixer/aerators can be used for efficient oxygenation and mixing. Where waste water is purified, sludge is generated. This sludge is generally conditioned using polymers, dewatered, and then digested in anaerobic sludge digesters to generate biogas. Special agitators are required for both polymer introduction and for digested sludge mixing.
