Anaerobic treatment of glycol contaminated wastewater for methane production
(Masteroppgave/UIS-TN-IMN/2011;, Master thesis, 2011)Glycols are usually used in the offshore gas industry as hydrate inhibitor in gas pipelines laid deep under the sea. Glycols, in its use, are contaminated by dissolved salts from formation water together with scaling and ... -
Anaerobic Treatment of Municipal Wastewater at Mesophilic and Psychrophilic Temperatures Using Bench Scale Upflow Anaerobic Sludge Blanket (UASB) Reactors
(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 ... -
Biological effects of pharmaceuticals around a marine wastewater outfall – a case study in Rogaland, Norway
(Masteroppgave/UIS-TN-IKBM/2020;, Master thesis, 2020-01)In this thesis, farmed Mytilus edulis were caged and deployed at three locations at the coastline of the North Sea to monitor the potential biological effect related to the presence of pharmaceuticals in the marine ... -
Biological response in organisms collected near the discharge point of the wastewater treatment plant of Stavanger
(Studentoppgave/UIS-TN-IKBM/2021;, Master thesis, 2021-06-01)The effluent from the IVAR SNJ wastewater treatment plant is discharged into the marine recipient Håsteinsfjord in the North Sea, 1.6 kilometers from the coast of the Stavanger peninsula. The treated discharged wastewater ... -
Current wastewater treatment methods and emerging technologies with a focus on removal of pharmaceuticals.
(Masteroppgave/UIS-TN-IKBM/2020;, Master thesis, 2020-06)The global consumption of pharmaceuticals is increasing, and in recent years there has been a growing concern surrounding the release of pharmaceuticals to the environment. Wastewater treatment plants (WWTP) have been ... -
Effect of salinity on biological treatment of wastewater from oil industry
(Masteroppgave/UIS-TN-IMN/2009, Master thesis, 2009)High salinity may affect biological wastewater negative by reducing the growth rate of microorganisms. Wastewater from oil industry often contains high salinity which could be problematic to treat. This thesis is to evaluate ... -
Effect on solids separation from wastewater with varying aeration and mixing conditions
(Masteroppgave/UIS-TN-IKBM/2018;, Master thesis, 2018-06-15)The main objective of this review was to analyze the effect on the separation of solids from wastewater with different conditions of aeration and mixing in order to compare their efficiency when both processes act ... -
Energy optimization of biological wastewater treatment using rotating belt filters upstream BNR
(Doctoral thesis, 2020-04)Treatment of wastewater to acceptable permit standards requires energy, mostly as electricity. The typical energy demand for various wastewater treatment technologies vary from 0.30 to 1.50 kWh/m3 of treated water. For ... -
Environmental harm assessment of a wastewater discharge from Hammerfest LNG: A study with biomarkers in mussels (Mytilus sp.) and Atlantic cod (Gadus morhua)
(Journal article; Peer reviewed, 2013-04)Biologically treated wastewater (WW) from the Hammerfest LNG (liquefied natural gas) plant is discharged to the sea. A study using biomarkers in mussels and Atlantic cod was performed to examine whether this discharge meets ... -
Improving BOD removal at SNJ wastewater treatment plant by biological treatment
(Masteroppgave/UIS-TN-IMN/2010;, Master thesis, 2010)SNJ uses chemical precipitation method to treat domestic wastewater. With regard to organic removal requirement; chemical treatment alone does not seem to be sufficient at SNJ/IVAR wastewater plant. This thesis is to assess ... -
Improving BOD removal at SNJ wastewater treatment plant by biological treatment at low temperature
(Masteroppgave/UIS-TN-IMN/2010;, Master thesis, 2010)Nowadays, the use of microorganisms in wastewater handling known as ‘biological treatment’ becomes more and more popular. Better results can be achieved with this process. SNJ, one of the biggest chemical wastewater ... -
