1. 31. Renewable energy from wastewater grown microalgae - a concept for nutrient recycling and sustainable energy recovery

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Stina Lidén; [2015]
   Keywords : sustainable wastewater treatment; vattenförsörjningsteknik; avloppsteknik; renewable energy; nutrient reduction; nutrient recycling; microalgae; AnMBBR; biogas; Technology and Engineering;

   Abstract : Wastewater is an excellent source of nutrients and energy. By treating the wastewater in a clever way, it is possible to both recycle nutrients and recover energy, and thereby create opportunities for a sustainable system. READ MORE

3. 32. High-loaded Activated Sludge: Effects of Different Aeration Strategies at Sjölunda WWTP

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Gabriel Persson; [2015]
   Keywords : methane potential; High-loaded activated sludge; activated sludge modelling; aeration strategies; ASM2d; vattenförsörjningsteknik; avloppsteknik; water engineering; environmental engineering; Technology and Engineering;

   Abstract : The activated sludge process has existed for over a century and despite its age the development of new theories, methods and technologies is ongoing. Despite huge technological breakthroughs in the last decades the activated sludge process is still a very energy demanding process however, and it is possible to make significant energy savings by optimizing the aeration strategy of an activated sludge plant.

4. 33. Wastewater to renewable energy at a tapioca factory in Vietnam

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Anna Gustafsson; [2015]
   Keywords : Vietnam; biogas; tapioca; cassava; anaerobic digestion; wastewater treatment; minor field study; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Chemistry;

   Abstract : Anaerobic digestion is a cost-effective way of treating high organic content wastewater, as it efficiently removes large amounts of organics at the same time as biogas is produced. The production of starch from cassava roots, named tapioca, creates large amounts of high organic content wastewater and uses large amounts of thermal energy for drying the starch. READ MORE

5. 34. Evaluation of Biological Hydrolysis Pre-treatment and the Biogas Potential of Sludge from Compact Waste Water Treatment

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Lina Falk; [2015]
   Keywords : biological sludge hydrolysis; biogas; biochemical methane potential tests; compact waste water treatment; drum filter; anaerobic digestion; microfiltration; environmental engineering; water engineering; avloppsteknik; vattenförsörjningsteknik; Chemistry;

   Abstract : Med anledning av de ökande utsläppskraven för avloppsreningsverk kommer ökade resurser i form av elektricitet och kemikalier att krävas om dagens teknologi ska användas även i fortsättningen. Följaktligen undersöks för tillfället mer effektiva metoder, vilka tillåter inte bara rening av avloppsvattnet utan även erbjuder en möjlighet att ta tillvara på de resurser som finns i avloppsvattnet.

6. 35. Stormwater management in Gaborone - A study of the quality and quantity of water in Segoditshane River

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Hanna Palm Johansson; Elin Andersson; [2015]
   Keywords : water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Technology and Engineering;

   Abstract : This master thesis was partly performed as a field study in Gaborone, the capital city of Botswana, located in southern Africa. The semi-arid climate in Botswana together with a rapid financial development in the country during the last decades has increased the need for water. READ MORE
