1. Investigation of Solids Distribution and External Solids Flux in a Circulating Fluidized Bed Boiler
Sammanfattning : This work concentrates on two issues regarding combustion in circulating fluidized bed (CFB) boilers. Firstly, the impact of co-combustion of coal with sewage sludge on ash flows, bed material and gas concentrations in a CFB boiler is studied. LÄS MER
2. Micro-by-micro interactions : Aggregation dynamics, biofilms, and ecotoxicological impacts of suspended solids
Sammanfattning : Increasing concerns arise regarding the environmental risk of microplastics (MP) and their interactions with biota, prompting numerous effect studies. However, current ecotoxicology methods fall short when it comes to assessing MP impacts. LÄS MER
3. Fuel dispersion and bubble flow distribution in fluidized beds
Sammanfattning : Fluidized bed technology is used for thermal conversion of solid fuels (combustion and gasification) and is especially suitable for conversion of low-rank fuels such as biomass and waste. The performance of fluidized bed units depends on the fuel mixing and fuel-gas contact. LÄS MER
4. The Technology and Economy of Farm-Scale, High-Solids Anaerobic Digestion of Plant Biomass
Sammanfattning : Anaerobic digestion is a microbially mediated process occurring in nature in the absence of oxygen and other non-carbonaceous electron acceptors. The majority of the carbon of the organic matter degraded in the process is transformed into carbon dioxide and methane. LÄS MER
5. Wastewater treatment in constructed wetlands : Effects of vegetation, hydraulics and data analysis methods
Sammanfattning : Degradation of water resources has become one of the most pressing global concerns currently facing mankind. Constructed Wetlands (CWs) represent a concept to combat deterioration of water resources by acting as buffers between wastewater and receiving water bodies. LÄS MER
