Espeland, Mathias (Master thesis, 2016-08-30)A number of studies and comments have tried to find the cause of Chronic Kidney Disease of unknown etiology (CKDu) which has stricken the North Central Province (NCP) of Sri Lanka during the last two decades. The preliminary ... -
Comparison of treatment and fouling mitigation efficiency of organic and inorganic coagulants in biofilm membrane bioreactor
Shostak, Vladyslav (Master thesis, 2019)Membrane bioreactors is an exemplary practice of sustainable wastewater treatment. Novel methods and approaches incorporating MBR allow not only treat wastewater with excellent efficiency, but also recover nutrients, recycle ... -
Effects of electrochemical treatment of mixed liquor in submerged ceramic membrane bioreactor
Nehrii, Anastasiia; Kuzhel, Roman (Master thesis, 2019)Our most valuable and irreplaceable resource is water. Humanity withdraws 3.928 km3 of freshwater per year. Approximately 44% is used for agricultural purposes, the other 56% discharged as wastewater (WW). A large amount ... -
Electrochemical oxidation of per- and polyfluoroalkyl substances (PFAS) for wastewater treatment and UV-VIS quantification
Lein, Philip (Master thesis, 2022)Proper wastewater treatment is vital to remove organic matter as well as persistent pollutants. That affects the biospheres that effluent is discharged to if not treated sufficiently, which has negative effects on the ... -
Electrocoagulation in wastewater treatment : a review
Granhus, Thea Caroline (Master thesis, 2020)Vann er vår mest verdifulle ressurs og essensielt for mennesker. Fortsatt har en stor del av verdens befolkning ikke tilgang til trygt vann og sanitærtjenester. Mer enn 80 \% av det genererte avløpsvannet blir i dag ikke ... -
Flux enhancers in biofilm membrane bioreactors : insight into fouling control
Kulesha, Olga (PhD Thesis;2019:83, Doctoral thesis, 2019)Conventional wastewater treatment technologies are not able to keep up with the population growth and new challenges and restrictions, induced by climate change. Membrane bioreactor (MBR) technology has a high potential ... -
Muligheter for å effektivisere og utvikle fornyelsen av vann- og avløpsnettet med kompetanseløft, innovative anskaffelser og samspillskontrakter
Moen, Sofia Basma (Master thesis, 2022)Det norske ledningsnettet for vann og avløp står overfor en rekke utfordringer de neste tiårene. Det er høy lekkasjeandel og utskiftningsraten møter ikke behovet for fornyelse. Etterslepet på vedlikehold fører til et behov ... -
