Master thesis / Internship in modelling of densified activated sludge in sequencing batch reactor (DAS\-SBR) Eawag, the Swiss Federal Institute of Aquatic Science and Technology, is an internationally networked aquatic research institute within the ETH Domain (Swiss Federal Institutes of Technology). Eawag conducts research, education and expert consulting to achieve the dual goals of meeting direct human needs for water and maintaining the function and integrity of aquatic ecosystems. The Department of Process Engineering (ENG) has a vacancy for a Master thesis / Internship in modelling of densified activated sludge in sequencing batch reactor (DAS\-SBR) Densified Activated Sludge (DAS), a hybrid system consisting of flocs and small granules (typically 200\~500 ?m in diameter), is a promising solution for the increasing stringent effluent quality standards and the intensification of biological processes in wastewater treatment. Compared to conventional activated sludge, DAS offers significant advantages to "do more with less" \- increasing treatment capacity without expanding the plant footprint. The improved settleability enables high biomass retention, thereby substantially increasing volumetric treatment capacity. The enrichment of slow\-growing bacteria, particularly nitrifiers, promotes microbial activities and provides greater flexibility for optimizing aeration strategies for enhancing nutrient removal. The application of DAS in sequencing batch reactors (SBR) is being increasingly investigated and implemented worldwide, yielding many new valuable experimental findings and operational experience. However, a comprehensive understanding of long\-term performance of DAS\-SBR systems under dynamic conditions remains limited. Existing mathematical models do not yet adequately represent all relevant processes and characteristics, nor have they been calibrated and validated using real\-world operational data. This project aims to develop a DAS\-SBR model in Sumo, w
