A Comparison of Theoretical and Measured Pressure Losses Within a Drinking Water Treatment Plant
(Master thesis, 2016)Pressure loss and its effects on the resulting hydraulics within a drinking water treatment plant are extremely important aspects of design and operation. Pressure losses are important to monitor as they are the driving ... -
Assessment of Downspout Disconnection by Modeling Infiltration Potential in Urban Areas
(Master thesis, 2016)Climate change, which leads to more intense precipitation, combined with an increase of impervious surface, due to an increase of urbanization, has resulted in an increasing amount of stormwater entering the sewer system. ... -
Characterization of photocatalytic materials used for water treatment
(Master thesis, 2015)As the pressure on water bodies throughout the world is increasing, good water quality obtained through water treatment is essential to secure health and welfare of the population. Many chemical compounds used in industry ... -
Evaluering av overvannshåndteringen ved Urriðavatn, Island
(Master thesis, 2015)Denne masteroppgaven handler om å evaluere overvannshåndteringen ved næringsparken Kauptún på Island i utkanten av Reykjavik. Programvaren MIKE URBAN fra DHI er benyttet til å modellere avrenning for å undersøke om feltet ... -
Forurensninger i overvann og datasimuleringer av first flush - Modellering av forurensningskonsentrasjoner i overvann gjennom en nedbørshendelse
(Master thesis, 2015)Sammenlignet med spillvann, ses gjerne overvann på som relativt rent. Ved separering av ledningsnett kan derfor overvann noen ganger slippes urenset ut i resipienten. Det er likevel slik at overvann inneholder en rekke ... -
Hydrological Assessment of Water Resources in Bergen - Climate Change Impacts
(Master thesis, 2015)Bergen Waterworks is reliant on steady loads of precipitation to meet the drink- ing water demand. Accordingly, the system is vulnerable to drought events and seasonal changes in inflow. Climate change impact analysis, as ... -
Investigation of the adsorption and biodegradation capacity of filter media towards airport de-icing chemicals
(Master thesis, 2016)At airports in Norway, propylene glycol (PG) and potassium formate (PF) are used as de-icing chemicals to provide safe air traffic. Expected climate changes will lead to temperatures more frequently around zero degrees, ... -
Modeling Biological Nutrient Removal in a Greywater Treatment System
(Master thesis, 2015)Many urban centers suffer water scarcity due to increased population growth and dry periods. There has been an increased interest in developing alternative water sources for supplementing the existing urban water supply ... -
Quantification of Bacterial Adhesion and Characterization of Polymeric Pristine and Modified UF Membranes
(Master thesis, 2016)Membrane filtration is an important technology that might help solving future challenges regarding the access to potable drinking water. One of the main challenges in membrane operations is biofouling. Biofouling is the ... -
Soil Moisture Measurements and Evapotranspiration in Extensive Green Roofs
(Master thesis, 2016)In his master's thesis, a concept within stormwater management, the green roof, will be examined. The first part of this thesis is a literature study on the hydrology of extensive green roofs and the factors influencing ... -
Testing of Infiltration System for Stormwater - Permeable Pavement
(Master thesis, 2016)In this master thesis it is focused on permeable pavement and with an extra focus on permeable interlocking concrete unit blocks as the type of pavement. This is because the test facility in Sandnes is built with this type ... -
The Effect of pH, Dissolved Metals and Suspended Minerals on the Hydrolysis of Neonicotinoids
(Master thesis, 2016)Neonicotinoids are a chemical class of insecticides that is registered in more than 120 countries and widely used all over the world. In recent years, neonicotinoids have been in the spotlight for their negative effects ...
