1. 16. Circularity Assessment of Water and Waste in Cities : A Proposed Framework for Sustainable Performance Evaluation using LCA and LCC

   Författare :Kavitha Shanmugam; Venkata Krishna Kumar Upadhyayula; Mats Tysklind; Runar Brännlund; Brajesh Dubey; Umeå universitet; []
   Nyckelord :Life cycle assessment; life cycle costing; environmental externalities cost; sustainable city; circularity; wastewater treatment; organic waste; waste to energy; assessment framework; environmental science; miljövetenskap;

   Sammanfattning : Urbanization is a global phenomenon, happening on a massive scale and at a rapid rate, with 68% of the planet’s population predicted to be living in cities by 2050 (UN-DESA, 2018). The sustainability of a city (Goal 11 of UN SDGs) undergoing rapid urbanization depends on its ability to maintain a low consumption of resources and materials at any given time (referred to as the urban metabolic rate), whilst simultaneously providing essential municipal services to its inhabitants, such as a water supply, wastewater treatment and solid waste management.

   Sammanfattning : Human society has taken many measures to address environmental issues. For example, deploying wastewater treatment plants (WWTPs) to alleviate water pollution and the shortage of usable water; using waste-to-energy (WtE) plants to recover energy from the waste and reduce its environmental impact.

4. 18. Integrated sewage sludge treatment scenarios – techno-economic analysis on energy and phosphorus recovery

   Författare :Marzieh Bagheri; Elisabeth Wetterlund; Marcus Öhman; Lale Andreas; Roozbeh Feiz; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sewage sludge management; techno-economic analysis; phosphorus recovery; thermochemical treatment; Energy Engineering; Energiteknik;

   Sammanfattning : Sewage sludge is a by-product of wastewater treatment that simultaneously gathers contaminants, valuable organic matter, and nutrients. The treatment of the increasing amount of sewage sludge is important from both pollution prevention and resource recovery perspectives as i) large shares of mineral phosphorus, listed as a critical raw material, terminate in the sewage sludge, and ii) energy recovery from sewage sludge can cover the energy-intensive demand of the treatment process.

5. 19. Solar-based physicochemical-biological processes for the treatment of toxic and recalcitrant effluents

   Författare :Tamer Essam; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; combined process; biodegradaiton; phenolics; phenol; Advanced Oxidation Processes; Photodegradation; photolysis;

   Sammanfattning : Wastewater treatment is a worldwide necessity that is even more crucial to countries deprived from abundant fresh water sources or unable to afford advanced and costly processes. With this perspective, this thesis was conducted within an Egyptian-Swedish research collaboration that aimed to develop solar-based (as free renewable energy source available locally) process for hazardous wastewater treatment.

7. 20. Applying coagulation, flocculation and discfiltration in tertiary treatment

   Författare :Janne Väänänen; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Reducing eutrophication in our surface waters caused by nutrient overload is of importance in order to ensure an environment in ecological balance for future generations. Municipal wastewater treatment plants are the main point source of nutrients emissions. LÄS MER
