We are pleased to share that a new research article has been published in Open Transport, led by FlashPhos coordinator University of Stuttgart and with contributions from our project partner Buss-SMS-Canzler GmbH.
The paper, Pilot drying-grinding system for pulverized sewage sludge production, presents innovative work on integrating drying and grinding steps for sewage sludge to produce finely pulverized material suitable for thermal processes. The study explores a pilot-scale thin-film drying-grinding prototype designed as part of the FlashPhos project. It investigates how operational parameters, such as rotor speed, feed rate, and temperature, influence sludge particle size, dryness, and process performance. Key findings highlight the importance of mechanical shear for particle size reduction and offer insights for future optimization and scale-up of phosphorus-recovery technologies.
We extend our thanks to the authors, Ayumi Schober, Juan Pablo Segovia-Gutiérrez, Matthias Rapf, Florian Drunsel, Glykeria Duelli, and Natalie Germann, for their valuable contribution to advancing sustainable thermal processing and phosphorus recovery research.
