1. 1. Mainstream Deammonification process monitoring by bacterial activity tests

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Andrea Carranza Muñoz; [2020]
   Keywords : Ammonia Oxidizing Bacteria AOB ; Anammox; Bacterial activity; Deammonification; Heterotrophic bacteria; IFAS; Mainstream wastewater; Nitrite Oxidizing Bacteria NOB ; Nitrogen Removal.;

   Abstract : Deammonification is a widely used technology for side stream treatment with rich ammonium streams at relatively high temperatures, such as, the reject water coming from dewatering units in treatment of digested sludge and industrial wastewaters. The deammonification process has lower operational costs than conventional systems, consumes less energy, enables the increase of biogas production and it is easy to implement. READ MORE

3. 2. Comparison of anaerobic sludge granules from different wastewater plants with respect to granule size, substrate degradation and methanogenic community

   University essay from SLU/Department of Molecular Sciences

   Author : Jonathan Andrén; [2018]
   Keywords : anaerobic digestion; granule; UASB; EGSB; VFA; methanogen; acetoclastic; hydrogenotrophic; acetogenic; mcrA; ; T-RFLP; methanosarcina; methanosaeta;

   Abstract : Within the objective to replace fossil fuel with sustainable sources there is a growing pressure to advance such development. Anaerobic digestion (AD) is beneficial not only as a waste management technology, but also to recycle organic waste into methane which can be used for heating, production of electricity or vehicle fuel.

4. 3. Nitrogen removal from municipal wastewater by mainstream Partial Nitritation/Anammox process

   University essay from KTH/Vatten- och miljöteknik

   Author : Alessio Robiglio; [2018]
   Keywords : Mainstream; Deammonification; IFAS; UASB; Anammox; Anoxia; Aeration; Online; Monitoring; Inhibition; Wastewater;

   Abstract : Mainstream Partial Nitritation/Anammox, also known as Mainstream Deammonification, is a promising technology for future wastewater purification that aims to remove nitrogen from wastewater in order to prevent the eutrophication. It is less costly than the traditional nitrification/denitrification process and it heads towards the direction of converting the WWTPs from energy consuming into energy producing facilities.

5. 4. Deammonification efficiency in combined UASB and IFAS system for mainstream WWT

   University essay from KTH/Mark- och vattenteknik

   Author : Noureddine Khayi; [2017]
   Keywords : Ammonium; Nitrite; Nitrate; Deammonification; UASB; MBBR; DO; Aeration; monitoring; on-line control;

   Abstract : The study is about Nitrogen removal from the low concentrated mainstream wastewater after Upflow Anaerobic Sludge Blanket reactor process (UASB) by single-stage Partial Nitritation/Anammox process in a pilot scale reactor at Hammarby Sjöstad in Stockholm. A mixture of various concentrations of dissolved oxygen and different aeration methods have been tested in the pilot scale reactor in five months divided into five periods where the temperature was set at 15° C throughout the study.

6. 5. Strategies of improvement ofUASB reactor operation

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Daria Klesyk; [2017]
   Keywords : ;

   Abstract : The Upflow Anaerobic Sludge Blanket (UASB) reactor is one from the most widely used anaerobic technology to remove organic matter from wastewater, popular mostly in countries with warm climate but use all over the world. UASB reactor have mainly advantages: during organic matter removal biogas is produced, low energy consumption and simplicity of work. READ MORE
