11. Analysis and optimization of a dissolved air flotation process for separation of suspended solids in wastewater
Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : Margretelund wastewater treatment plant (WWTP) operated by the water utility Roslagsvatten AB, wasbuilt in 1956 and is located in Åkersberga town, Stockholm County, Sweden. Margretelund WWTP waslast renovated in 1999, and has been operated with the same physical, chemical, and biological processessince then. LÄS MER
12. Modelling control strategies for chemical phosphorus removal at Tivoli wastewater treatment plant
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Wastewater compose an environmental risk as it contains high levels of nutrients, including phosphorus. Wastewater treatment plants (WWTPs) reduce phosphorus by using coagulants that precipitate soluble phosphate into metal phosphate, which is separated by settling. LÄS MER
13. Evaluation of a gross pollutant trap-biofilter stormwater treatment train : The Role Of Calcium Carbonate, Vegetation And Pre-Treatment Facility
Master-uppsats, Luleå tekniska universitet/Arkitektur och vattenSammanfattning : Development of cities, new buildings and other impervious surfaces entails increased stormwater flows, volumes and pollutant loads. Heavy metals, nutrients, sediments and salt are common pollutants in stormwater. LÄS MER
14. Hydrolysis of waste activated sludge from pulp and paper mills : effect on dewatering properties and biogas potential by utilizing existing side streams
Master-uppsats, Linköpings universitet/Tema MiljöförändringSammanfattning : A big challenge within pulp and paper mills is the large quantities of waste activated sludge (WAS) that is produced during the wastewater treatment. The WAS is made up of biological cells and extra polymeric substances (EPS) and can bind a large amount of water causing difficulties to dewater the WAS. LÄS MER
15. Assessment of on-site wastewater treatment systems in unsewered communities in Jordan
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Centralized wastewater treatment systems need substantial funds besides high-cost operation and maintenance programs, which could be considered unsuitable for low-income developing countries. As a solution, it becomes the trend towards on-site wastewater treatment systems (OWTs) due to its cost-effectiveness and flexibility of implementation and management. LÄS MER
