   Abstract : Margretelund wastewater treatment plant (WWTP) operated by the water utility Roslagsvatten AB, wasbuilt in 1956 and is located in Åkersberga town, Stockholm County, Sweden. Margretelund WWTP waslast renovated in 1999, and has been operated with the same physical, chemical, and biological processessince then. READ MORE

3. 2. Hydraulics of lamella sedimentation.A study of the lamella settlers at Ringsjö water treatment plant, Sweden.

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Maria Lytra; [2019]
   Keywords : Lamella settling tanks; Inclined sedimentation; Ringsjö water treatment plant; Suspended solids separation; Technology and Engineering;

   Abstract : This study investigates the lamella settlers in Ringsjö water treatment plant, Sweden, in terms of water movement and performance. The treatment plant has two blocks with differences in the flocculation and lamella settlers, where block 1 is not able to process the maximum designed flow rate without the addition of polymers.

4. 3. Intensification of lignocellulosic bioethanol production process using multi-staged membrane bioreactors

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Clarisse Uwinez; [2019]
   Keywords : Interconnected continuous hydrolysis and fermentation; lignocellulosic bioethanol; Membrane bioreactors; process intensification; lignin recovery; membrane fouling.;

   Abstract : The exploitation of lignocellulosic materials with the aim of producing high value-added products will potentially counteract concerns related to the depletion of fossil resources or exponential population growth. Bioethanol produced from lignocellulosic agriculture residue exhibits promising alternative to the petroleum-based fossil fuel which reduces net emission of greenhouse gases (GHG). READ MORE

5. 4. OPEN STORMWATER SYSTEMS FOR REDUCTION OF HEAVY METALS : AN EVALUATION OF COMMONLY USED DIMENSIONING METHODS

   University essay from Mittuniversitetet/Avdelningen för ekoteknik och hållbart byggande

   Author : Johan Jönsson; [2018]
   Keywords : Stormwater; Heavy metals; Ponds; Filter strips; Wetlands;

   Abstract : In Östersund there are a few stormwater ponds and oil separation units   connected to the stormwater network, but mostly there is no systems for   filtration of stormwater before it is released into a nearby lake which acts   as Östersund’s source of drinking water. In the Industrial area in Lugnvik there   is an oil separation unit connected to the stormwater network but no other   means of filtration. READ MORE

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

   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.
