This is the first granulation study except Ferguson [Ferguson LN. Anaerobic codigestion of aircraft deicing fluid and microaerobic studies. M.S. Thesis. Milwaukee, WI, USA: Marquette University; 19991 to develop coupled granules by using a mixture of suspended anaerobic and aerobic cultures exposed to alternating cyclic anaerobic/microaerobic/aerobic conditions. Coupled granules with median sizes of 1.28-1.86 mm and settling velocities of 31-39 m/h were developed, which were comparable to those of both anaerobic and aerobic granules. Coupled granules displayed noteworthy specific methanogenic activity (SMA) and specific oxygen uptake rate (SOUR) as 14-42 mL CH4/g VSS h h and 6-47 mg DO/g VSS h, respectively, indicating that they were composed of both anaerobic and aerobic cultures.

Kinetics model for growth of Pseudomonas putida F1 during benzene, toluene and phenol biodegradation Abuhamed, T; Bayraktar, E; Mehmetoglu, T; Mehmetoglu, U (Elsevier BV, 2004-04-30) The effect of adaptation of Pseudomonas putida F1 ATCC 700007 (Pp F1) to the biodegradation of benzene (B), toluene (T) and phenol (P) was studied. The adaptation of microorganism to BTP decreased the biodegradation time from 24 to 6 It for benzene (90 mg/1) and toluene (90 mg/1), and from 90 to 18 It for phenol (50 mg/1). Andrews kinetics model for single substrate was solved to obtain maximum specific growth rates, half saturation and substrate inhibition constant. Cell growth using toluene (mu(max.T) = 0...
Degradation of chlorinated compounds by Penicillium camemberti in batch and up-flow column reactors Taseli, BK; Gökçay, Celal Ferdi (Elsevier BV, 2005-02-01) A Penicillium camemberti strain isolated in this laboratory was studied for its ability to degrade chlorinated compounds including pentachlorophenol (PCP), 2-chlorophenol and trichloroacetic acid. The batch experiments were conducted in shake flasks using PCP as co-substrate resulting in around 56% PCP removal by the fungus. Experiments in shake flasks not containing acetate but Tween 80, produced 86% of PCP and 53% of 2-chlorophenol removals in 21 days. PCP was also fed to a column reactor with an adsorbab...
Investigation of systemic change at a university preparatory language department: the northview case İpek, Ömer Faruk; Karaman, Abdullah Cendel; Department of English Language Teaching (2017) This qualitative explanatory case study provides insight into the self-initiated prescriptive and planned systemic change process at a university preparatory department called ‘Northview’ situated in the western part of Turkey. Although English is taught worldwide and there are many English language institutions, few studies have been conducted on the systemic aspect of English language teaching. Therefore, by using a conceptual framework and related literature, this study examined the reasons, components, ...
An application of depth analysis on middle bronze age palaces at Acemhöyük, Tell Mardikh, and Kültepe Eren, Güzin; Summers, Geoffrey; Department of Settlement Archaeology (2010) Many MBA buildings have been studied from different points of views and approaches; however, their spatial patterns were scarcely investigated. This thesis aims to assess the usefulness of Depth Analysis, a sub-method of Space Syntax, in the understanding of spatial patterns of MBA palaces. The palaces of key MBA sites, Acemhöyük, Tell Mardikh and Kültepe, were selected for the analysis. In the conclusion it is suggested that Depth Analysis can be a very useful method in understanding the configuration of s...
Anaerobic treatment of olive mill wastes in batch reactors Bayramoğlu, Tuba Hande; DEMİRER, GÖKSEL NİYAZİ (Elsevier BV, 2000-01-01) Anaerobic treatment of olive oil mill wastes, namely black water and prina, was investigated in batch reactors. Biochemical methane potential (BMP) tests were conducted to determine the anaerobic biodegradability of black water and/or prina. With these BMP tests the biodegradability of olive mill wastes (OMWs) at different initial chemical oxygen demand (COD) concentrations and corresponding methane gas productions were investigated. Furthermore, a screening study was performed to determine the most importa...
