Enhancement of coagulant dosing control in water and wastewater treatment processes
Liu, Wei (PhD Thesis;2016:62, Doctoral thesis, 2016)Chemical coagulation is one of the most important treatment processes in wastewater treatment and drinking water treatment. Defining the optimal coagulant dosage is a vital operation that decides the treatment efficiency ... -
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 ... -
Fremmedvann i avløpsnettet - analyser av påvirkningsfaktorer, konsekvenser og mulige tiltak
Sola, Kristin Jenssen (PhD thieses;2021:36, Doctoral thesis, 2021)Fremmedvann har fått et økt fokus både i Norge og i internasjonale forskningsmiljø de siste årene. Likevel har veldig mange norske kommuner fortsatt veldig høye andeler fremmedvann i avløpsnettet. Undersøkelser av ... -
Image analysis in coagulation process control
Sivchenko, Nataliia (PhD thesis;2018:9, Doctoral thesis, 2018)Coagulation-flocculation is a conventional process in drinking water, municipal and industrial wastewater treatment. This stage of wastewater treatment has become popular in Norway due to its superior ability to remove ... -
Innovative Surveillance and Process Control in Water Resource Recovery Facilities
Nair, Abhilash Muralidharan (PhD Thesis;2020:68, Doctoral thesis, 2020)Water Resource Recovery Facilities (WRRF), previously known as Wastewater Treatment Plants (WWTP), are getting increasingly complex, with the incorporation of sludge processing and resource recovery technologies. Along ... -
Modelling and optimisation of wastewater coagulation process
Rathnaweera, Subhash S. (PhD Thesis;2010:05, Doctoral thesis, 2010)The efficiency and economics of chemical coagulation, one of the most robust wastewater treatment processes, is critically dependent on the optimal coagulant dosage which is strongly related to the influent quality. The ... -
Optimisation of the coagulation process to improve plant availability of phosphorus in wastewater sludge
Manamperuma, Lelum Duminda (PhD Thesis;2016:61, Doctoral thesis, 2016)Coagulation is used for the removal of colloids, particles and phosphates in wastewater treatment. The efficiency and economics of chemical coagulation, one of the most robust wastewater treatment processes, is critically ... -
Optimisation of wastewater treatment systems with data mining and process modelling
Wang, Xiaodong (PhD Thesis;2018:43, Doctoral thesis, 2018)Wastewater treatment facilities serve an important purpose in public sanitation. Wastewater treatment plants (WWTP) are built at the end of sewerage systems to purify the wastewater before it enters natural water bodies. ... -
Sewer Overflow Control using Different Modeling Techniques and Internet of Things
Zhang, Duo (PhD Thesis;2019:55, Doctoral thesis, 2019)Increased urbanization and extreme rainfall events are causing more frequent instances of sewer overflow, leading to the pollution of water resources and negative environmental, health, and fiscal impacts. At the same time, ...
