The IWA Anaerobic Digestion Model No. 1 (ADM1) was used to simulate the full-scale anaerobic sludge digester of Ankara Central Wastewater Treatment Plant. The digester is a completely mixed, once through continuous flow type which is being fed with a primary and secondary sludge mixture. The variability and unpredicted nature of the primary sludge composition was expected to challenge the model. A one-year dynamic data set from the digester was used for model calibration and validation in the study. The standard ADM1 model was corrected in the study with regard to nitrogen and carbon mass balances. A good correlation between the measured and simulated data was obtained for biogas yield, total volatile fatty acids and pH after heuristically calibrating stoichiometric and kinetic parameters of the ADM1 model. The simulation is sensitive to influent composition.

Investigation of methane production potential of industrial sludges mixed with domestic sludge during anaerobic digestion Aksu Bahçeci, Hazal; Sanin, F. Dilek.; Department of Environmental Engineering (2019) Anaerobic digestion has been established as a sludge stabilization and biogas production method for domestic sludge. However, anaerobic digestion has limited success in industrial sludge applications. In this thesis sludge from two different Organized Industrial Districts (OIDs) and textile industry are mixed with urban wastewater sludge with and without ultrasound pretreatment to investigate their energy production potential by using BMP tests. Sludges were digested alone (A for industrial, D for domestic ...
EFFECT OF PRETREATMENTS ON THE SEMICONTINUOUS ANAEROBIC-DIGESTION OF SUNFLOWER HEADS POLAT, H; Selçuk, Nevin; SOYUPAK, S (1992-10-01) The effects of hydraulic retention time and alkali treatment on methane production rate from the semicontinuous anaerobic digestion of 2 % sunflower-head/water mixtures were investigated. The experiments were carried out in laboratory-scale fermenters, fed with 1 liter of untreated, 2 g NaOH/100 g total solids (TS), and 5 g NaOH/100 g TS alkali-treated sunflower-head/water mixtures, respectively, and maintained at 55-degrees-C Digestion experiments were performed for hydraulic retention times of 8, 10, and ...
Investigation of biogas production potential of three different sludges after thermal hydrolysis Arı Akdemir, Ece.; Sanin, F. Dilek.; Department of Environmental Engineering (2019) Biogas production through anaerobic digestion using biological sludge is one the sustainable approaches. Hydrolysis is the first and rate limiting step during anaerobic digestion. For enhancement of hydrolysis of sludge, it is feasible to investigate pre-treatment before anaerobic digestion process. In this research, biogas and methane production potentials of municipal wastewater treatment plants sludge, membrane bioreactor sludge and organized industrial district sludge were investigated using small scale...
Removal and recovery of nutrients as struvite from anaerobic digestion/co-digestion residues of poultry manure Yılmazel, Yasemin Dilşad; Demirer, Göksel Niyazi; Department of Environmental Engineering (2009) The main objective of this study was to investigate the removal and recovery of nutrients from anaerobic digestion residues of poultry manure through struvite (MgNH4PO4.6H2O, MAP) precipitation. To this purpose, three sets of laboratory experiments were conducted. In the first set, separate and co-digestion of poultry manure and sewage sludge were studied in laboratory-scale mesophilic anaerobic batch reactors and subsequent struvite precipitation experiments were conducted with the reactors effluents. The ...
Performance of leaching bed reactor converting the organic fraction of municipal solid waste to organic acids and alcohols DOĞAN, Evrim; Dunaev, T.; Bayramoğlu, Tuba Hande; DEMİRER, GÖKSEL NİYAZİ (2009-02-01) A lab-scale leaching bed reactor (LBR) was operated to (1) investigate the potential of in-vessel solid-state anaerobic digestion of the organic fraction of municipal solid waste (MSW) and (2) examine the feasibility of using LBRs for hydrolysis/liquefaction and acidification of organic fraction of MSW for maximum total volatile fatty acid (tVFA) and alcohol production. A hydrolysis efficiency of 60% was achieved in the LBR, which was mainly affected by the solids content of organic fraction of MSW, the amo...
