Investigation of the use of aerobic granules for the treatment of sugar beet processing wastewater

Bayramoğlu, Tuba Hande
The treatment of sugar beet processing wastewater in aerobic granular sequencing batch reactor (SBR) was examined in terms of chemical oxygen demand (COD) and nitrogen removal efficiency. The effect of sugar beet processing wastewater of high solid content, namely 2255 +/- 250mg/L total suspended solids (TSS), on granular sludge was also investigated. Aerobic granular SBR initially operated with the effluent of anaerobic digester treating sugar beet processing wastewater (Part I) achieved average removal efficiencies of 71 +/- 30% total COD (tCOD), 90 +/- 3% total ammonifiable nitrogen (TAN), 76 +/- 24% soluble COD (sCOD) and 29 +/- 4% of TSS. SBR was further operated with sugar beet processing wastewater (Part II), where the tCOD, TAN, sCOD and TSS removal efficiencies were 65 +/- 5%, 61 +/- 4%, 87 +/- 1% and 58 +/- 10%, respectively. This study indicated the applicability of aerobic granular SBRs for the treatment of both sugar beet processing wastewater and anaerobically digested processing wastewater. For higher solids removal, further treatment such as a sedimentation tank is required following the aerobic granular systems treating solid-rich wastewaters such as sugar beet processing wastewater. It was also revealed that the application of raw sugar beet processing wastewater slightly changed the aerobic granular sludge properties such as size, structure, colour, settleability and extracellular polymeric substance content, without any drastic and negative effect on treatment performance.


Influent COD/TAN ratio affects the carbon and nitrogen removal efficiency and stability of aerobic granules
KOCATURK, IREM; Bayramoğlu, Tuba Hande (2016-05-01)
Two identical sequencing batch reactors (SBRs) seeded with aerobic granules were operated with varying chemical oxygen demand/total ammonia nitrogen (COD/TAN) ratios (1-30). R1 was operated at increasing COD/TAN ratios (7.5, 10, 20, 30), while R2 was operated at decreasing COD/TAN ratios (7.5, 5, 3.5, 2, 1). The results indicated that high COD/TAN ratios (7.5-30) provided high COD removal efficiency (around 92%) and low TAN removal (33%), favoring heterotrophs that form white, fluffy flocs and large granule...
The effects of aerobic/anoxic period sequence on aerobic granulation and COD/N treatment efficiency
Erşan, Yusuf Çağatay; Bayramoğlu, Tuba Hande (Elsevier BV, 2013-11)
The effects of period sequence (anoxic-aerobic and aerobic-anoxic) on aerobic granulation from suspended seed sludge, and COD, N removal efficiencies were investigated in two sequencing batch reactors. More stable granules with greater sizes (1.8-3.5 mm) were developed in R1 (anoxic-aerobic sequence). Yet, no significant difference was observed between the reactors in terms of removal efficiencies. Under optimum operational conditions, 92-95% COD, 89-90% TAN and 38-46% total nitrogen removal efficiencies we...
Investigation of extraction methodologies for quantitative determination of polycyclic aromatic hydrocarbons in sediments
Topal, Tansel; Tuncel, Semra G.; Department of Chemistry (2011)
The extraction procedures for the determination of polycyclic aromatic hydrocarbons (PAH) concentrations in sediment samples had been developed by using GC-FID and GC-MS. The optimized methods were soxhlet extraction, ultrasonic bath extraction and solid phase micro extraction (SPME). In order to search out the main factors affecting extraction efficiencies of the methods, factorial design was used. The best extraction method was chosen and optimum values for main factors were selected for the development o...
Investigating the methane production efficiency of single- and two-phase anaerobic digestion and population dynamics of a second-phase anaerobic digestion
Koç, Engin; Bayramoğlu, Tuba Hande; Duran, Metin; Department of Environmental Engineering (2015)
The aim of this thesis study was to investigate the methane production efficiency of single-phase and two-phase anaerobic digestion (AD) in batch reactors and anaerobic sequencing batch reactor (ASBR). It was also aimed to monitor the population dynamics and change in the quantity of aceticlastic methane-producers of the second-phase of a two-phase ASBR. Two sets of batch reactors were conducted, namely, Batch Reactor Set-1 and Batch Reactor Set-2. The aim of Batch Reactor Set-1 was to investigate the effec...
Investigation into the microbiology of a high rate jet-loop activated sludge reactor treating brewery wastewater
Dilek, Filiz Bengü; Bloor, J. (1996-06-28)
The microbiology of a jet loop activated sludge reactor treating brewery wastewater has been investigated, with a venturi system combining liquid pumping with air diffusion being the basic feature of the system. The high F/M ratio, the high growth rate of the bacteria and the high levels of turbulence registered in the jet loop reactor caused the disappearence of filamentous bacteria and the production of a cloudy effluent. The population in the reactor was mainly formed by aerobic bacteria all belonging to...
