1. 6. HIGH LOADED ANAEROBIC MESOPHILIC DIGESTION OF SEWAGE SLUDGE : An evaluation of the critical organic loading rate and hydraulic retention time for the anaerobic digestion process at Käppala Wastewater Treatment Plant (WWTP).

   University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

   Author : Ibrahima Sory Gärdeklint Sylla; [2020]
   Keywords : Dewaterability; Mesophilic anaerobic digestion; Methane; Organic load rate; Renewable energy source; Sludge filterability; Wastewater treatment.; Avvattningsförmåga; mesofil anaerob rötning; metan; organisk belastning; förnybar energikälla; slammets filtrerbarhet; vattenrening;

   Abstract : Käppala wastewater treatment plant (WWTP) has, during a few years, observed an increase in organic loading rate (OLR) in the mesophilic anaerobic digester R100, due to an increased load to the WWTP. The digestion of primary sludge at Käppala WWTP is today high loaded, with a high organic loading rate (OLR) and low hydraulic retention time (HRT). READ MORE

3. 7. Environmental Impacts of a Wastewater Treatment Plant – With Sidestream Deammonification

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

   Author : Malin Ekman; [2020]
   Keywords : Deammonification; LCA; Life cycle assessment; WWTP; Wastewater treatment; Avloppsrening; Avloppsreningsverk; Deammonifikation; LCA; Livscykelanalys;

   Abstract : Människan ger upphov till avloppsvatten varje dag. Kommunalt avloppsvatten är rikt på kol, kväve och fosfor, vilka har en stor miljöpåverkan. Vattenrening är i och med detta en nödvändighet för att minimera den antropogena inverkan på naturen och den biologiska mångfalden. READ MORE

4. 8. Feedstock Recovery From Municipal Food Waste

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

   Author : Matilda Palmér; Anna Sandström; Sara Johansson; Josefin Eklund Wallin; [2020]
   Keywords : Feedstock Recovery; Food waste; Sludge; Anaerobic digestion; VFA;

   Abstract : Volatile Fatty Acids (VFAs) are a by-product when producing methane through anaerobic digestion (AD). Due to their many uses as building block chemicals, it is of interest to look into ways to optimize anaerobic digestion toward VFA production instead of methane generation. READ MORE

5. 9. 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

6. 10. Anammox in IFAS reactor for reject water treatment

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Bingquan Chen; [2019]
   Keywords : Deammonification; IFAS; Online sensors; Partial nitritation Anammox; Reject water; Specific anammox activity;

   Abstract : The aim of this study was to evaluate the performance of the integrated fixed-film activated sludge (IFAS) reactor achieving partial nitritation/anammox process to treat reject water after dewatering of digested sludge. During the study period, dissolved oxygen setpoint, aeration mode and inflow loading were changed to evaluate their influence on the process performance and efficiency in the reactor. READ MORE
