1. 1. The link between ESG and financial performance in sensitive and non-sensitive industries. A quantitative study of the European market

   University essay from Göteborgs universitet/Företagsekonomiska institutionen

   Author : Danait Abraham; Magnus Forslund; [2022-04-07]
   Keywords : ESG; financial performance; return; stakeholder theory; shareholder theory;

   Abstract : Purpose: The topic of ESG and its relationship with financial performance has been studied by researchers for the last decades. In this thesis, to further understand the relationship between ESG and financial performance, industry affiliation has been considered. READ MORE

3. 2. Comparison of mesophilic and thermophilic anaerobic sludge digestion at Hammarby Sjöstadsverk MBR pilot plant for wastewater treatment

   University essay from SLU/Department of Molecular Sciences

   Author : Jessica Sellin; [2021]
   Keywords : Anaerobic digestion; sludge; wastewater treatment; thermophilic; mesophilic; stress test;

   Abstract : Anaerobic digestion is a commonly used method for stabilisation of sewage sludge and production of biogas at municipal wastewater treatment plants (WWTPs). The hydraulic retention time for sludge in the digestion reactors is about 16 days at Henriksdal WWTP in Stockholm. READ MORE

4. 3. Hydrogeological assessment of springs and groundwater in Carrizal, Costa Rica

   University essay from Lunds universitet/Väg- och vattenbyggnad (CI); Lunds universitet/Teknisk geologi

   Author : Markus Beckman; Jacob Sannum; [2020]
   Keywords : Hydrogeology; volcanic aquifer; Water balance analysis; MBR; Costa Rica; double ring infiltrometer; spring characteristics; minor field study.; Technology and Engineering;

   Abstract : The main purpose of this thesis is to increase the understanding of how hydrogeological conditions are affecting the local water resources in Carrizal on the Barva Volcano, Costa Rica. Hydrogeological investigations of spring characteristics, soil infiltration rates and water flow in springs and rivers were conducted at the study area in Costa Rica as part of a Minor Field Study (MFS).

5. 4. Mapping spontaneous biological phosphorus removal in a membrane bioreactor process without the anaerobic condition : Investigating the effect of alternative external carbon sources

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Ross Roberts; [2020]
   Keywords : enhanced biological phosphorus removal; PAO; anoxic; carbon source; ethanol; ORP;

   Abstract : Phosphorus removal in wastewater treatment is commonly achieved by chemical precipitation, enhanced biological phosphorus removal (EBPR) or a simultaneous combination of the two. A defined anaerobic condition is widely regarded as the critical element to sustain EBPR. However, this study demonstrates that EBPR is indeed occurring in a 4. READ MORE

6. 5. Mapping of spontaneous biological phosphorous removal in MBR-process

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Benjamin Fridh; [2020]
   Keywords : Polyphosphate poly-P ; Phosphorous;

   Abstract : An unexpected biological removal of phosphorous in IVL Hammarby Sjöstadsverket pilot membrane bioreactor (MBR) wastewater treatment process was investigated by three distinct methods. a) Investigation and quantification of the biological phosphorous uptake (bio-P) capacity by phosphate release tests (PRT), b) validation of bio-P occurrence by granular polyphosphate (poly-P) staining and microscopy and c) metagenomic community structure analysis to map the sludge habitat.
