21. Skumproblematik i avloppsreningen vid Holmen Bravikens pappersbruk : Orsak och lösningsförslag
Master-uppsats,Sammanfattning : The treatment of industrial wastewater is an important measure to prohibit eutrophication and intoxication of lakes and oceans. Major industries often have location-basedwastewater treatment and to avoid undesired effluents it is essential to make it robust. LÄS MER
22. Optimizing Growth Conditions for Lactic Acid Bacteria
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : High production titers are paramount in lactic fermentation processes aimed towards poly lactic acid (PLA) manufacturing. Optimization of the fermentation stage is therefore essential for the viability of the process. LÄS MER
23. Removal of per- and polyfluoroalkyl substances(PFAS) from contaminated leachate usingaeration foam fractionation
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Leachate from landfills is contaminated in many ways and per- and polyfluoroalkyl substances (PFAS)-contamination is one of them. Recent studies have demonstrated the environmental and human concerns of PFAS. Therefore, the treatment of leachate is important. LÄS MER
24. Greenhouse gas emissions from compacted peat soil
Master-uppsats, SLU/Dept. of Soil and EnvironmentSammanfattning : Cultivated peat soils are a main driver for CO2 and N2O emissions, while the gas fluxes are dependent on intrinsic soil properties and land use. Sand addition into peat soils might reduce greenhouse gas (GHG) emissions and enhance soil strength, and thus the ability to tolerate soil compaction. LÄS MER
25. Numerical Study on Air Demand of Free Surface Flows in a Discharge Tunnel
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : Aeration issued through a ventilation shaft is an important measure to prevent cavitation and large gauge pressure in flood discharge tunnels. In order to dimension the ventilation shaft appropriately, itis necessary to have a good understanding of the air-water flow in the tunnel. LÄS MER
