1. Water quality improvement of highway runoff by the filter material D-Rainclean : A five-month field trial
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Highway runoff and its pollutants are of growing concern. These pollutants require treatment as their concentration often are increased. A common removal method is the use of sedimentation ponds that removes particulates through gravity. LÄS MER
2. How the Choice of Primary Treatment Affects the Biogas Potential of Primary Sludge
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : The global heating has resulted in rising temperatures and more extreme weather conditions around the world. In combination with increasing energy demands, this has led to an increasing demand of renewable energy. One option is utilizing the wastewater to produce biogas. There-fore, wastewater can be seen as a resource rather than waste. LÄS MER
3. Undersökning av turbiditet och föroreningars sammansättning i urbana vatten
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Stormwater is water that originates from snow or rainfall and that cannot naturally infiltrate the soil. When stormwater flows from hard surfaces it can transport different pollutants to watercourses. By measuring turbidity continuously and using the relationship between turbidity and pollutants the pollutant levels can be estimated. LÄS MER
4. Evaluating the suitability of carbon source from fermentation of primary filter sludge for biological nutrient removal
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : Traditional biological nutrient removal (BNR) processes in wastewater treatment require access to easily biodegradable carbon in order to achieve sufficient removal. However, a lot of the carbon in the influent wastewater is not directly available for BNR bacteria but need to undergo hydrolysis first. LÄS MER
5. Water quality and organic matter linkages in waters draining arable fields
Master-uppsats, SLU/Dept. of Soil and EnvironmentSammanfattning : This study investigated leaching of natural organic matter (NOM) in twelve Swedish arable fields with regards to the quality of dissolved organic matter (DOM) and particulate organic matter (POM), using Absorbance (UV-Vis) and fluorescence spectrometry (EEM). DOM is defined as organic matter (OM) 0.45 μm. LÄS MER
