  1. 6. Microscopic Investigation of Filamentous Microorganisms in Activated Sludge Process for Sewage Treatment

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Lilian Lawson; [2018]
    Keywords : Floating sludge; foaming; wastewater; bulking; filamentous microorganisms; fungi; yeast-like; bacteria;

    Abstract : Hammarby Sjöstadsverk is a pilot plant operated by IVL Swedish Environmental Research Institute and Royal Institute of Technology (KTH) which treats municipal wastewater. Different processes are used of which one is a Sequential Batch Reactor (SBR) with activated sludge process. READ MORE

  3. 7. Evaluation of Nitration/Anammox process by bacterial activity tests.

    University essay from KTH/Mark- och vattenteknik

    Author : Anna Mika; [2015]
    Keywords : Partial Nitritation Anammox process; Integrated fixed-film acti-vated sludge IFAS reactor; Batch tests; Specific Anammox Activity SAA ; Nitrate Uptake Rate NUR ; Oxygen Uptake Rate OUR ; Ammonium Oxi-dizing Bacteria AOB ; Nitrite Oxidizing Bacteria NOB ; Heterotrophic bac-teria;

    Abstract : Partial Nitritation/Anammox process (deammonification process), by which occurs oxidation of ammonium to nitrogen gas by autotrophic bacteria in anaerobic conditions, considered to be cost-effective and environmentally friendly method of nitrogen removal. Present research work focuses on achieving a high nitrogen removal degree, thanks to Anammox bacteria, while providing the best performance of the ongoing process. READ MORE

  4. 8. Performance Indicator Analysis as a Basis for Process Optimization and Energy Efficiency in Municipal Wastewater Treatment Plants

    University essay from Institutionen för informationsteknologi

    Author : Elin Wennerholm; [2014]
    Keywords : Performance indicators; wastewater treatment; process performance; energy efficiency; secondary treatment; Nyckeltal; avloppsvattenrening; processprestanda; energieffektivisering; biologisk rening;

    Abstract : The aim of this Master Thesis was to calculate and visualize performance indicators for the secondary treatment step in municipal wastewater treatment plants. Performance indicators are a valuable tool to communicate process conditions and energy efficiency to both management teams and operators of the plant. READ MORE

  5. 9. Investigation of the treatment process at Kungsberget's wastewater treatment plant under periods of irregular and low loads

    University essay from Institutionen för informationsteknologi

    Keywords : SBR; sequence batch reactor; wastewater treatment; Kungsberget; oxygen supply; phosphorous; seasonal load; solids retention time SRT .;

    Abstract : At Kungsberget ski-resort in Gävleborg county all wastewater produced at the facility is treated on-site. The treatment takes place at their own wastewater treatment plant in a so-called Sequence Batch Reactor (SBR), which has been in operation for about a year before this study. READ MORE

  6. 10. Starch and Protein based Wood Adhesives

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Lidija Glavas; [2011]
    Keywords : wood adhesive; starch; protein; polymer; renewable filler;

    Abstract : Different native starches, modified starches and plant proteins were evaluated as wood adhesives. They were combined with different synthetic polymers in order to achieve improved adhesive properties. The study was divided into two parts: development of starch based adhesive formulations and evaluation of an existing protein based adhesive. READ MORE
