Municipal wastewater treatment using salsnes filter and hollow fiber membrane bioreactor (HMFB)
(Masteroppgave/UIS-TN-IMN/2014;, Master thesis, 2014-07-04)This study investigated the performance of Salsnes Filter (SF) as a primary treatment prior to hollow fiber membrane bioreactor (HFMB) for nitrogen removal. The objective was to determine whether influent particle size ... -
Nanostructured titanium dioxide: fate in the aquatic environment and effects on the marine mussel mytilus edulis
(Masteroppgave/UIS-TN-IMN/2011;, Master thesis, 2011)The rapid development of nanotechnology and the corresponding increase in the use of nanoparticles in commercial products have led to concerns about their health risks and environmental impact. As the aquatic systems act ... -
Negative feedback loops leading to nitrate homeostasis and oscillatory nitrate assimilation in plants and fungi.
(Masteroppgave/UIS-TN-IMN/2011;, Master thesis, 2011)Nitrate is an important nutrient for plants and fungi. For plants it has been shown that cytosolic nitrate levels are under homeostatic control. Here we describe two networks that can obtain robust, i.e. perturbation ... -
New Microwave Technology for the Treatment of Drill Cuttings
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017)The focus of this thesis was to investigate the limitations of the new microwave susceptor technology. The technology offers promising opportunities in the treatment of oil contaminated drill cuttings to meet OSPAR and oil ... -
Optimization of chemical and mechanical disintegration process of drilling fluids.
(Masteroppgave/UIS-TN-IMN/2015;, Master thesis, 2015-06)Drilling fluids are essential to conduct any drilling process. The amount of oil-based mud used daily is significant. Additives present in an oil-based mud ensure both unique properties and require proper waste treatment. ... -
