Anaerobic Treatment of Municipal Wastewater at Mesophilic and Psychrophilic Temperatures Using Bench Scale Upflow Anaerobic Sludge Blanket (UASB) Reactors
Quansah, Kobina Andam (Masteroppgave/UIS-TN-IKBM/2019;, Master thesis, 2019-06-15)The limitation of high TSS wastewater treatment is hydrolysis. At low temperatures, the hydrolytic rate limitation is exacerbated. This project investigates the operational conditions required to improve the hydrolytic ... -
Analysis of the Antibiotic Ampicillin in Activated Sludge: Method Development and Adsorption Studies
Håland, Mari Wøien (Masteroppgave/UIS-TN-IKBM/2019;, Master thesis, 2019-06)The presence of antibiotics in wastewater treatment plants is a concern, both because of potential release to natural water systems, and connected to the spread of antibiotic resistance genes. In this thesis, the focus is ... -
Antimicrobial Resistance and the circular economy of water
Hermansen, Morten Flaata (Master thesis, 2022)I takt med en økende global befolkning og en voksende industri, har utslippene av klimagasser økt, blir stadig større oppmerksomhet blitt rettet mot arbeidet for en mer bærekraftig fremtid. Verden har en stadig økende ... -
Biodegradation and chemical characterization of petroleum diesel hydrocarbons in seawater at low temperatures
Bausch, Alexandra Renee (Masteroppgave/UIS-TN-IMN/2010;, Master thesis, 2010-06)Petroleum hydrocarbons are a major source of marine contamination. Biodegradation, which is fundamental for the natural attenuation of these hydrocarbons in nature, involves mineralization or transformation of organic ... -
Bioengineered methanotrophic photogranules for tertiary UASB effluent post-treatment.
Bakke, Andreas (Master thesis, 2022)The need for aeration when treating wastewater is the most extensive energy requirement wastewater treatment plants (WWTP) has today. This thesis investigated an attached growth process which utilise genetic features in ... -
Biogas Potential of Municipal Wastewater Treatment using Up-Flow Anaerobic Sludge Blanket (UASB) reactors under Psychrophilic Condition
