(Masteroppgave/UIS-TN-IKBM/2018;, Master thesis, 2018-06-13)Exploration and development drilling activities in offshore Oil and Gas industry generates waste streams, which slop water are among the significant wastes. Slop water is formed when wastewater originating from multiple ... -
Methods for determining the activity of nitrifying bacteria in wastewater samples
(Masteroppgave/UIS-TN-IMN/2016;, Master thesis, 2016-06-15)The present study investigated the feasibility of nitrification in wastewater and the community structure of nitrifying bacteria at two different temperatures, 10 and 25°C. The experiment was conducted in sequencing batch ... -
Microbiology of Lava Tube Skylights on Earth: Implications for Astrobiology
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-03-15)Microbial life is abundant in Earth’s subsurface and is extremely diverse. Subsurface habitats on extraterrestrial bodies offer microorganisms protection from hostile surface conditions. Lava tube caves are widespread on ... -
Possible inhibitory effect of selected detergents used in food industry on wastewater treatment and especially on Grødaland wwtp.
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)Grødaland waste water treatment plant (wwtp) is treating industrial waste water coming from food industry. As food industry consumes large amounts of detergents for food processing equipment cleaning, the wwtp receives ... -
Preliminary study of nanofiltration for production of smart water from produced water
(Masteroppgave/UIS-TN-IMN/2014;, Master thesis, 2014-07-15)Production of smart water from produced water is the focus of the thesis. Smart water performance is regulated by the concentration of ions such as Ca2+, Mg2+ and SO42-. Choosing produced water as the source for smart water ... -
