Cavitation-based antimicrobial process water treatment as a means of promoting environmentally friendly and resource-efficient paper production
It is impossible to imagine modern life without paper and cardboard products. Their production using wet processes requires very large amounts of water. To reduce water consumption, the process water is circulated in largely closed loops. The use of recycled paper as raw material and the resulting introduction of nutrients into the process water promote the growth of microorganisms. Biocides are often used to curb this growth. The KaPPa research project focuses on treating process water using hydrodynamic cavitation as an alternative.
The goal of the project is to develop a cavitation-based process suitable for practical application and energy-efficient for the microbial treatment of process water with high solids content by combining experimental and numerical studies on a laboratory scale with process engineering investigations using a test facility and a pilot plant directly in paper mills. The Chair of Fluid Mechanics (PSM) is responsible for the laboratory experiments and flow simulations and provides scientific support for the process engineering studies conducted by the project partners.
