11. Simulating water and pollutant transport in bark, charcoal and sand filters for greywater treatment
Sammanfattning : A septic tank combined with a sand filter is the most common onsite wastewater treatment system worldwide, since it is a simple, lowcost and reliable treatment method. Alternatives to sand in filters could be advantageous in terms of availability of material and enhanced treatment properties. LÄS MER

13. Benzene-char conversion and particle-vapor characterization in biomass gasification
Sammanfattning : Biomass is increasingly attracting attention as an alternative to fossil fuels. Gasification permits the thermochemical conversion of biomass into a product gas rich in carbon monoxide and hydrogen. The product gas can be further processed to generate heat, electricity, synthesis gas, chemicals, and biofuels. LÄS MER
14. Drying and Pyrolysis of Logs of Wood
Sammanfattning : This work concerns log firing in small-scale boilers for house heating, which in Sweden meets a heat demand of 12 TWh a year. In boilers used for domestic central heating in the sizes of 10 to 30 kW the predominant combustion technique is grate firing. LÄS MER
15. Mild Wet Torrefaction and Characterization of Woody Biomass from Mozambique for Thermal Applications
Sammanfattning : Mozambique has vast forestry resources and also considerable biomass waste material such as bagasse, rice husks, sawdust, coconut husks and shells, cashew nut shell and lump charcoal waste. The potential of the total residues from the agricultural sector and the forest industry is estimated to be approximately 13 PJ. LÄS MER
