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 ... -
Assessing the hydraulic performance of a combined sewer system under climate change using temporal downscaling
(Master thesis, 2018)In recent years, climate change has lead to an increasing number of high intensity rain events causing flooding in urban areas around the world. Studies of different future climate scenarios indicate that this increase ... -
Assessing the robustness of raingardens under climate change using SDSM and temporal downscaling
(Master thesis, 2017)Climate change is expected to lead to higher precipitation amounts and intensities. This study was carried out to (1) estimate the future precipitation extremes in Bergen (Norway) and (2) assess the robustness of raingardens ... -
Assessment and Control of Methods for Flow Measurement Systems - Master of Civil and Environmental Engineering
(Master thesis, 2017)This Master thesis is about the Palmer-Bowlus flume measuring open channel flow rates of waste water at Risvollan. The Department of Civil and Environmental Engineering at the University of Science and Technology (NTNU) ... -
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. ... -
Assimilerbart organisk karbon i drikkevann i Trondheim
(Master thesis, 2018)Å opprettholde tilfredsstillende drikkevannskvalitet til enhver tid kan være en krevende oppgave. Råvannets karakteristikk, vannbehandlingsprosessen og distribusjonssystemet er alle faktorer som påvirker kvaliteten på ... -
Biological Phosphorous Removal in a Continuous MBBR - Daily monitoring, observations and kinetic experiments during the start-up phase
(Master thesis, 2018)My master thesis is a small part of a larger project called RECOVER. The overall aim of RECOVER is to research the sustainability and reusability of wastewater resources. This master thesis investigates biological removal ... -
Bærekraftige strategier for rehabilitering av vann- og avløpsnettet
(Master thesis, 2017)Planlegging av utskiftningsmetoder for vann og avløp bør utføres i et langt tidstidsperspektiv. Enkelte effekter kommer ikke fram i et kort tidsperspektiv, men inkluderes derimot i et langt et. Planlegging av denne ... -
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 ... -
Classification of wastewater manholes, procedures and opportunities by applying machine learning
(Master thesis, 2018)Wastewater manholes are not subject to proper condition assessments in the same manner as pipes. Although manholes have a significant impact on the performance of the wastewater system, no official procedures for how to ... -
Comparing experimentally measured runoff coefficients with field observations for detention-based roofs
(Master thesis, 2018)Predicted climate changes combined with urbanization increases the performance demand on urban stormwater management structures. The rational method with the runoff coefficient (C) is one of the most commonly used design ... -
Deteksjon av fremmedvann i separatsystemer med isotoper
(Master thesis, 2017)Utgangspunktet for denne oppgaven er å definere egnetheten til en hittil lite utprøvd metode for lekkasjesøking i separate spillvannsledninger. Rent praktisk tar metoden utgangspunkt i å benytte stabile isotoper i ulike ... -
Dewatering of backwash water containing cyanobacterias by wedge wire and geotextile drying beds
(Master thesis, 2018)Treatment of effluents are processes with the aim to decrease contaminants to a level were it can be returned to a water source with minimal impact on the environment. In order to release effluents, treatment goals set by ... -
Enhanced Biological Phosphorus Removal in Typical Norwegian Wastewater
(Master thesis, 2017)Discharge of wastewater containing excess amounts of nutrients such as phosphorus (P) cause eutrophication of the receiving waterbodies. The consequences related to eutrophication can vary in severity, from esthetical ... -
Evaluating Hydrological Performance of LID-Modules in Mike Urban - A Case Study of CSO Reduction in Grefsen, Oslo
(Master thesis, 2018)Paved surfaces, increased precipitation amounts and intensities in addition to limited capacity in the sewer systems, cause a higher risk of combined sewer overflows (CSOs). Low impact development (LID) is a possible ... -
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 ... -
Fremmedvann i separatsystemer
(Master thesis, 2015)Fremmedvann er uønsket vann i spillvannsystemet og er et problem som kan medføre store kostnader for samfunnet. Det er derfor av interesse å se på metoder vurdere mengden av fremmedvannet samt lokalisere innlekkings- og ... -
