1. 1. 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).

3. 2. 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

4. 3. Limiting microplastic pollution from municipal wastewater treatment : A circular economic approach

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Jordy van Osch; [2020]
   Keywords : Microplastics; circular economy; wastewater treatment plant; resource recovery; Multi-criteria analysis;

   Abstract : The increasing amount of microplastics found in the environment have underscored the urgency to identify, develop and deploy scenarios in which municipal wastewater treatment plants (MWWTPs) limit the release of urban microplastics into the environment. Simultaneously, the global trend towards a circular economy has defined the conditions for these scenarios in relation to the water-energy- nutrient nexus. READ MORE

5. 4. Energieffektivisering och förbättrat resursutnyttjande vid Främby avloppsreningsverk i Falun

   University essay from SLU/Dept. of Energy and Technology

   Author : Maria Silfwerin; [2019]
   Keywords : Energikartläggning; biogas; slam; rötning; membranbioreaktor; aktivslamprocess;

   Abstract : Främby wastewater treatment plant, a 50 000 population equivalent (pe) municipal sewage treatment plant in Falun, faces large changes as aging technology, increasing load and stricter effluent quality requirements lead to a demand for upgrading the plant. The owner of the plant, Falu Energi & Vatten (FEV), have a vision of an energy neutral plant in the future. READ MORE
