21. Modelling the full-scale N2O emissions from wastewater treatment plants for identifying mitigation strategies
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : Nitrous oxide (N2O) emissions, which primarily originate from the biological nitrogen removal process, dominate the release of greenhouse gases (GHGs) in wastewater treatment plants (WWTPs). N2O production occurs through dynamic microbial pathways that have a significant impact on the environment compared with other GHG emissions. LÄS MER
22. High-loaded thermophilic anaerobic digestion of mixed sewage sludge : A pilot study
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Municipal wastewater treatment plants (WWTP) are important infrastructural components in a society and also important for sustainability. In a WWTP the most common treatment configuration is mechanical, biological, and chemical treatment of the wastewater. LÄS MER
23. Potential for Enhanced Biological Phosphorus Removal in an activated sludge system for greywater
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : As the world's population grows, concerns about water scarcity and rising pollution such as phosphorus and nitrogen have increased significantly. Greywater has been considered by researchers as an ideal alternative to fresh water for decades, and several projects have been implemented to treat and recycle it for various reuse purposes. LÄS MER
24. Continuous leaching of phosphorus from sewage sludge ash
Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : The global demand for food is increasing. Different nutrients are used to increase growth in agriculture and are thus essential for the world ́s food supply. An important and common nutrient is phosphorus. It can be mined, in the form of phosphate, from phosphate rock. LÄS MER
25. 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
