11. 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
12. Occupational health and safety risks in the wood recycling industry of Lithuania
Kandidat-uppsats, Linnéuniversitetet/Institutionen för skog och träteknik (SOT)Sammanfattning : A good Occupational Health and Safety (OHS) is needed to reach sustainability. OHS consists of three parts: 1) physical, 2) mental and 3) social. The purpose of this study was to explore and foresee the main physical OHS risks when upscaling the recycling of wood in Lithuania, with the goal to prevent those risks. LÄS MER
13. A case study of estimating Algal biomass productivity from wastewater treatment facilities in the state of Texas and possible use
Master-uppsats, KTH/KemiteknikSammanfattning : För att hålla vattendragen och miljön rena, renas avloppsvattnet för att nå ett visst mått innan det släpps ut. Vi gjorde en fallstudie för att utvärdera metoderna som används för att behandla avloppsvatten i tre steg: primär, sekundär och tertiär i delstaten Texas, USA. LÄS MER
14. Phosphorous Precipitation in Source Separated Greywater for Direct Environmental Release.
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : As our understanding of the impact humans have on the environment changes, so too do the mitigation strategies we employ to prevent it. One major source of anthropogenic pollution is wastewater effluent. LÄS MER
15. PFAS- En sammanfattning av ny forskning, med ett fokus på föroreningskällor, provtagning, analysmetoder och saneringsmetoder
Kandidat-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : PFAS (per- and polyfluoroalkyl substances) is a large group of pollutants that, over the last decade have been of great academic concern since it has been found all around the globe. PFAS is ubiquitous in our environment and frequently found in low background concentrations in soil and water; recent research has also found that PFAS occur in biotic samples, such as fish and plants.
