Treatment of industrial effluents has long been a challenge for modern technologies combining high effectiveness of degradation of pollutants with low costs of the process. At the same time, new technological developments should incorporate the concept of green chemistry[i]. It is thus an interesting area of research dealing with the development of effective technologies for degradation of specific chemical compounds or selected groups of pollutants. A recent trend in treatment of industrial effluents involves the use of advanced oxidation processes combined with hydrodynamic cavitation[ii]. This is a promising alternative to the technologies of wastewater treatment which is in use today, because it is capable of degrading organic material and is an effective method for the disinfection of water. It is of great importance for Carlsberg to reduce the water consumption and the carbon footprint of its breweries. Carlsberg has therefore launched a program called Together Towards Zero and Wastewater treatment is a natural part of this. The outcome of this project will therefore support our sustainability goals and could potentially also be published.

In this project we are looking to describe the rotational hydrodynamic cavitation reactor by CFD simulation. More specifically, it is of interest to describe where the cavitation occurs, which parameters influence the intensity and how to maximize its efficiency. This knowledge can then be transferred to a pilot scale setup where we can validate the simulation with experiments.

Technical University of Denmark

For almost two centuries DTU, Technical University of Denmark, has been dedicated to fulfilling the vision of H.C. Ørsted – the father of electromagnetism – who founded the university in 1829 to develop and create value using the natural sciences and the technical sciences to benefit society.


Today, DTU is ranked as one of the foremost technical universities in Europe, continues to set new records in the number of publications, and persistently increases and develops our partnerships with industry, and assignments accomplished by DTU’s public sector consultancy.
