2. 1. District Heating-driven Membrane Distillation for Water Purification in Industrial Applications

   Author : Daniel Minilu Woldemariam; Andrew Martin; Massimo Santarelli; Wojciech Kujawski; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membrane Distillation; District Heating; Wastewater Purification; Heat demand; Technoeconomy; Membrandestillation; Fjärrvärme; Avloppsvattenrening; Värme-behov; Teknoekonomi; Energy Technology; Energiteknik;

   Abstract : Domestic and industrial water demands are growing globally due to population growth and rapid economic development, placing increasing strains on water resources. Wastewater effluents generated from these and other activities impact the environment and are thus subject to tightening regulation. READ MORE

4. 2. Performance Assessment of Wastewater Treatment Plants : Multi-Objective Analysis Using Plant-Wide Models

   Author : MAGNUS ARNELL; Ulf Jeppsson; Bengt Carlsson; Hans Bertil Wittgren; Diego Rosso; Industriell elektroteknik och automation; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; benchmarking; BSM; samrötning; energieffektivitet; växthusgasutsläpp; livscykelanalys; matematisk modellering; avloppsvattenrening; benchmarking; BSM; codigestion; energy efficiency; greenhouse gases; life cycle assessment; mathematical modelling; wastewater treatment; benchmarking;

   Abstract : 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. READ MORE

5. 3. Removal of organic micropollutantns from wastewater in a Swedish context

   Author : Maja Ekblad; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wastewater treament; ozone; ozonation; pharmaceutical residues; Organic micropollutants; driving forces; drivers; avloppsvattenrening; ozon; ozonering; läkemedelsrester; organiska mikroföroreningar; drivkrafter;

   Abstract : Due to their potential environmental risk, the abatement of organic micropollutants from wastewater has gained increasing attention in recent years. This thesis evaluates the use of ozone in Swedish wastewater treatment plants (WWTPs) and the incentives for full-scale implementation of organic micropollutant removal. READ MORE

6. 4. Sludge-derived char : utilisation as a metal sorbent in dilute wastewaters

   Author : Ida Sylwan; Eva Thorin; Lena Johansson Westholm; Konrad Koch; Mälardalens universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sorption; adsorption; sludge; biosolids; metal; wastewater treatment; sorption; adsorption; slam; metaller; avloppsvattenrening; Energy- and Environmental Engineering; energi- och miljöteknik;

   Abstract : Metal concentrations in soil and water have increased since the Industrial Revolution, which may have negative health and environmental effects. Metal pollution occurs, for instance, in municipal wastewater, industrial wastewater, and stormwater. Concentrations are often low, due to dilution. A common technology for metal removal is sorption.

7. 5. Investigation of a Biofilm Reactor Model with Suspended Biomass

   Author : Alma Masic; Matematik LTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; wall attachment; suspended growth; substrate removal; reactor; biofilm; CSTR; mathematical model; MBBR; nitrification; optimization;

   Abstract : Biofilms are compact, sessile microbial communities that attach to surfaces in aqueous environments. In wastewater treatment, they are especially important for removal of phosphorus and nitrogen, which, if released into a receiving water body, can cause severe eutrophication. READ MORE
