"Performance Assessment of Wastewater Treatment Plants - Multi-Objective Analysis Using Plant-Wide Models"

Magnus Arnell

As the knowledge about anthropogenic impacts of climate change has grown, the awareness of the contributions from treatment of wastewater has widened the scope for wastewater treatment plants (WWTPs). Not only shall ever stricter effluent constraints be met, but also energy efficiency be increased, greenhouse gases mitigated and resources recovered. All under a constant pressure on costs. The main objective of this research has been to develop a plant-wide modelling tool to evaluate the performance of operational strategies for multiple objectives at the plant and for off-site environmental impact.

The plant-wide model platform Benchmark Simulation Model no. 2 (BSM2) has been modified to improve the evaluation of energy efficiency and include greenhouse gas emissions. Furthermore, the plant-wide process model has been coupled to a life cycle analysis (LCA) model for evaluation of global environmental impact. For energy evaluation, a dynamic aeration system model has been adapted and implemented. The aeration model includes oxygen transfer efficiency, dynamic pressure in the distribution system and non-linear behaviour of blower performance. To allow for modelling of energy recovery via anaerobic co-digestion the digestion model of BSM2 was updated with a flexible co-digestion model allowing for dynamic co-substrate feeds. A feasible procedure for substrate characterisation was proposed. Emissions of the greenhouse gases CO2, CH4 and N2O were considered. The bioprocess model in BSM2 was updated with two-step nitrification, four-step denitrification and nitrifier denitrification to capture N2O production. Fugitive emissions of the three gases were included from digestion, cogeneration and sludge storage. The models were tested in case studies for the three areas of development: aeration, co-digestion and greenhouse gas production. They failed to reject the hypothesis that dynamic process models are required to assess the highly variable operations of wastewater treatment plants. All parts were combined in a case study of the Käppala WWTP in Lidingö, Sweden, for comparison of operational strategies and evaluation of stricter effluent constraints. The averaged model outputs were exported to an LCA model to include off-site production of input goods and impact of discharged residues and wastes. The results reveal trade-offs between water quality, energy efficiency, greenhouse gas emissions and abiotic depletion of elemental and fossil resources.

The developed tool is generally applicable for WWTPs and the simulation results from this type of combined models create a good basis for decision support.

Cross-functional discussion on energy and future:

"The purpose is a discussion across the electrical engineering research at IEA, to work towards a common view of the future RENEWABLE energy system. If you are not a part of IEA you are still invited because we are interested in your view and in the collaboration we may develop." Programme

Organised by Lars Lindgren and Mats Alaküla

Master Thesis presentation:

"Energy Harvesting Device"

Driton Salihu

Abstract: This thesis evaluates the concept of Energy Harvesting as a power source for a serial measurement board used by ABB robots. A background study of possible energy harvesters is included, where the main focus is laid on the overall function and what parameters determine the maximum generated power and efficiencies. Furthermore, a design of a physical proof of concept for solar as an Energy Harvesting Source is examined. The design consists of solar cells as Harvester, a Power Management Integrated Circuit for managing power requirements of the host system and an Energy Storage to be used when the source is not available. The host system, i.e. the SMB consumes a maximum power of 1 mW. The designed Energy Harvesting System used in this thesis generates a maximum power of 1.73 mW at a light intensity of 700 Lux.

"Automation for a Sustainable and Reliable Power System"

Olof Samuelsson

Summary: "Electricity plays a key role in the transition to a sustainable energy system. The overall challenge is to make the best of existing electric power system assets combined with new options like power electronics, solar electricity, GPS-based measurements and involving end users. Using automation for this results in what is often referred to as smart grid solutions. This forms an important part of my activities and I will describe these but also how a few LTH individuals have influenced my career."
