Master Student for Modeling the effects of drastic changes in wastewater quality and quantity on sewer systems
Increasing the efficiency of urban wastewater systems is a critical challenge for global sustainability. In most affluent cities, centralized wastewater infrastructures are widely established. However, in many cases, these investment intensive centralized systems may no longer provide the best solution. These cases may include situations in which expensive rehabilitation is needed or when flexibility of the systems is desired due to anticipated changes in climate, in land use and in demography. Attractive technical alternatives to replace or complement existing centralized systems are widely being developed. These include novel systems for drastic reduction in domestic water consumption and for decentralized wastewater reuse. Decentralized systems allow to provide desired flexibility and the localization of required services and performances. Implementation of such systems changes the quality and quantity of the wastewater discharged to the sewer system. Such changes can negatively affect the operation of exciting centralized systems. These effects may include phenomena of the accumulation of solids in sewer pipes, increasing rates of blockages and the formation of unpleasant or toxic gases (such as volatile organic acids, hydrogen sulfide or methane). In the proposed Master research
, we aim at analysing the effects of changes in wastewater quantity and quality on the operation of sewer systems. This will be part of a research investigating the feasibility of transition from a fully centralized system with high water consumption to a system integrating decentralized water reuse systems. The research will consist of following main steps
We are looking for
- Set up three case studies of sewer systems in an integrated simulator, SIMBA#
- Implement a detailed model of the processes occurring in sewer systems on the different case studies
- Simulate the model for various scenarios of changes in wastewater quantity and quality
- If time allows: stochastically analyze the results with the aim to develop a simplified model predicting the locations and magnitudes of solids accumulation and toxic gas production in a sewer system where changes in its wastewater discharges occur
