Anaerobic digestion found limited use in sludges from industrial wastewater treatment plants (WWTPs). So, it is of interest to assess the biodegradability and co-digestion performance of industrial sludges of biological origin alone and when mixed with municipal sludge. In this study, sludge from two different organized industrial districts (OIDs) and textile industry WWTPs are individually mixed with municipal sludge with and without ultrasound pretreatment to investigate their energy production potential and digestibility using biochemical methane potential tests. Sludges were used at different mass ratios in reactors with F/M ratio of 1. During operation, biogas amount and methane percentage were measured. Before and after reactor operation, total solids (TS), volatile solids (VS), chemical oxygen demand (COD) and pH were measured as performance indicators of digestion. Methane production potential was highest in reactors containing only municipal sludge and lowest containing only industrial sludge. The specific methane production normalized with COD removed for OID I, OID II and textile sludges were 0.13 L/g, 0.11 L/g and 0.11 L/g, respectively; whereas average specific methane production for municipal sludge was 0.31 L/g. COD, TS and VS reductions were lower in industrial sludges compared to domestic sludge. The co-digestion reactors with mixed industrial and municipal sludge performed in accordance with the proportion of two sludges. Ultrasonication improved the digestion performance. Although adding industrial sludge reduced the observed biogas amount to lower than that expected, results show that it is possible to co-digest some industrial sludges with municipal sludge in closely coordinated additions (about < 20%).

Co-occurrence of Antibiotic and Heavy Metal Resistance in Kizilirmak River Isolates İçgen, Bülent (2014-12-01) Contamination of surface waters with antimicrobials has become an increasing public health concern because of the emergence of multi-resistant pathogens. For this reason, water samples collected from the Kizilirmak River-Kirikkale, Turkey were analysed to learn more about the co-occurrence of heavy metal and antibiotic resistance in bacteria. Resistant profiles were determined by using 26 antibiotics and 17 heavy metals. Out of 290, 24 isolates with both heavy metal and antibiotic resistance were determined...
Application of ADM1 model to a full-scale anaerobic digester under dynamic organic loading conditions Ozkan-Yucel, U. G.; Gökçay, Celal Ferdi (2010-01-01) 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 sta...
Use of calcium alginate as a coagulant in water treatment Çoruh, Hale Aylin; Sanin, Faika Dilek; Department of Environmental Engineering (2005) Coagulation and flocculation processes are important parts of water and wastewater treatment. Coagulation or destabilization of colloidal suspensions results in aggregation of colloidal particles by physical and chemical processes. Flocculation results in the formation of larger and settleable structures by bridging. Alginate, a polysaccharide obtained from marine brown algae, produces a gel structure when mixed with calcium ions, which is expected to be a potential coagulant in water treatment. This study ...
Behavior of sulfate-reducing bacteria in single-stage anaerobic digesters pretreated with ozone Tuncay, Sera; Akcakaya, Merve; İçgen, Bülent (null; 2019-10-28) Anaerobic digestion is a solid stabilization process commonly used at both municipal and industrial wastewater and sludge treatment. Anaerobic digesters convert the microbiological cells and other solids generated during the treatment process to a stable end product and also produce methane-rich biogas as an energy source through the degradation of organic matter. Microbial population dynamics involved in anaerobic digestion are not well-studied yet due to the requirement of an extensive investigation of mi...
Two-stage anaerobic digestion of ozonated sewage sludge predominantly took over by acetotrophic methanogens with increased biogas and methane production Akcakaya, Merve; Tuncay, Sera; İçgen, Bülent (2022-06-01) Ozonation of sewage sludge prior to single-stage anaerobic digestion (SAD) has been reported to increase biogas and/or methane production. However, no studies have evaluated the impact of ozone pre-treatment on two-stage anaerobic digestion (TAD) of sewage sludge over the production of these renewable fuels. Present study, therefore, aimed at investigating the impact of 0.06 g O3/g TSS ozone-pretreated sewage sludge on the productivity of mesophilic semi-batch lab-scale TAD and on its methanogenic consortiu...
