1. 11. Determination of the methane potential of blue mussels

   Kandidat-uppsats, Institutionen för bygg- och energiteknik (BE)

   Författare :Birte Wollak; [2013]
   Nyckelord :Biogas; dry digestion; blue mussels;

   Sammanfattning : The aim of this study was to evaluate the methane potential of 35 kg of blue mussels in a batch amanaerobic two-stage dry digestion system (pilot-scale), which consists of aleach bed reactor (LB) and an up-flow anaerobic sludge blanket reactor (UASB). We monitored the process daily by measuring temperature, pH, COD, VFA, NH4+ gas flow rate and gas content. LÄS MER

3. 12. Systems for ammonium concentration for further removal in the partial nitritation/anammox technology.

   Master-uppsats, KTH/VA-teknik, Vatten, Avlopp och Avfall

   Författare :Isaac Owusu-Agyeman; [2012]
   Nyckelord :Ammonium; Anammox; conductivity; dissolved oxygen; ion-exchange; nitrogen; partial nitritation; regeneration; reverse osmosis;

   Sammanfattning : Anammox is one of the main processes discovered quite recently for removal of ammonium from wastewater. Anammox process is cost effective, in that low energy and carbon source is needed. LÄS MER

4. 13. Dokumentation av en experimentell biogasanläggning

   Kandidat-uppsats, Institutionen för datavetenskap, fysik och matematik, DFM

   Författare :Kamaran Eliassi; [2012]
   Nyckelord :;

   Sammanfattning : This thesis is   focused on identifying and documenting all   electrical equipment, such as devices, power lines / cables, and connectors in the facility and also on presenting a brief   technical description and information of the systems around the reactors.   Furthermore there will be a brief description of LabVIEW - which is a   graphical programming language- and which devices / elements   are programmed.

5. 14. Use of Manganese Compounds and Microbial Fuel Cells in Wastewater Treatment.

   Master-uppsats, KTH/VA-teknik, Vatten, Avlopp och Avfall

   Författare :Junli Jiang; [2011]
   Nyckelord :Digested Sludge; Manganese Compounds; Microbial Fuel Cell; Potassium Permanganate;

   Sammanfattning : Manganese compounds have a high potential for treating wastewater, both for utilizing its oxidation, flocculation ability and catalyst ability in anaerobic nitrification. The promising use of manganese compounds (such as permanganate and manganese dioxide) is regarded as an effective method of treating organic compounds in wastewater from municipal and industrial wastewater.

7. 15. High rate biogas production from waste textiles

   Magister-uppsats, Högskolan i Borås/Institutionen Ingenjörshögskolan

   Författare :Karthik Rajendran; Gopinath Balasubramanian; [2011]
   Nyckelord :biogas; waste textiles; nmmo-pretreatment; two-stage anaerobic digestion; UASB; CSTR;

   Sammanfattning : Textile is a global product used by all people in the world. These textiles after the use are thrown into the trash for incineration or land filling. However an efficient way that can be used to produce more energy, in an environmentally friendly process is anaerobic digestion. Waste textiles which contain cellulosic fibers (e. LÄS MER
