1. Environmental aspects of coal mine drainage: a regional study of Moatize in Mozambique
Sammanfattning : Mozambique is one of the largest coal producers in Africa. Extraction of the coal is carried out in the Moatize district of the Tete province in the center of the country. A surface mining technique is used to extract the coal below ground level. LÄS MER
2. A passage to wastewater nutrient recovery units : Microalgal-Bacterial bioreactors
Sammanfattning : In recent years, the microalgal–bacterial process has been considered to be a very attractive engineering solution for wastewater treatment. However, it has not been widely studied in the context of conventional wastewater treatment design under Swedish conditions. LÄS MER
3. 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
4. Bark and charcoal filters for greywater treatment : pollutant removal and recycling opportunities
Sammanfattning : Water scarcity, inappropriate sanitation and wastewater pollution are critically important global issues. Greywater is a sustainable water source for recycling, so this thesis examined simple, robust, low-cost alternatives for on-site treatment of greywater to irrigation water quality. LÄS MER
5. When bioelectrochemical systems meet extremophiles, possibilities and challenges
Sammanfattning : Extremophiles are microorganisms live and thrive in extreme environments that are harsh and hostile to most forms of life on earth (e.g. low pH, low temperature, high pH and high salinity). They have developed strategies to obtain nutrients and conserve energy to sustain life under these adverse conditions. LÄS MER
