In this period of the research, aerobic and anaerobic digestion, characterization of alkaloids present and radiolysis products formed after irradiation, under different conditions of ambient and additives, optimization of dose to achieve desired end characteristics for discharge of waste water were aimed. In this regard, unirradiated and irradiated wastewaters were subjected to aerobic and anaerobic digestions. Substrate removal efficiencies of unirradiated and irradiated wastewater with various initial COD values were determined with SBR aerobic digestion treatment method. On the other hand Fenton’s advanced oxidation treatment method was also applied for pre-treatment. BMP tests of anaerobic digestion were also completed. LC/MS studies were carried out on unirradiated and irradiated alkaloid standard solutions of morphine, codeine, thebaine, papaverine, and noscapine to determine the degradation mechanisms and byproducts. Dose optimization studies were completed and found to be a lower dose of 5 kGy rather than 40 kGy for ambient irradiation conditions

Anaerobic treatment of dilute wastewaters
Alptekin (Ener), Emel; Demirer, Göksel Niyazi; Department of Environmental Engineering (2008)
In this study, domestic wastewater was used to determine the anaerobic treatment performances of a dilute wastewater in one-phase upflow anaerobic sludge blanket (UASB) system and two-phase upflow anaerobic filter (UAF) and UASB system. The acidification performances of domestic wastewater were compared in UAF and UASB reactors. The degree of acidification is higher in UAF reactor (31%) compared to UASB reactor (18%) at 2 h hydraulic retention time (HRT) in the anaerobic treatment of domestic wastewaters. T...
Kinetic analyses of the effects of temperature and light intensity on growth, hydrogenm production and organic acid utilization by rhodobacter capsulatus
Sevinç, Pelin; Gündüz, Ufuk; Department of Biotechnology (2010)
Effects of temperature and light intensity on photofermentative hydrogen production by Rhodobacter capsulatus DSM1710 by use of acetic and lactic acids as substrates were studied. Experiments were conducted at 20, 30 and 38oC incubator temperatures under light intensities in the 1500 – 7000 lux range. pH of the medium and quantity of hydrogen forming together with quantity of biomass, and concentrations of acetic, lactic, formic, butyric and propionic acids in the medium were determined periodically. Growth...
Anaerobic mesophilic co-digestion of sugar-beet processing wastewater and beet-pulp in batch reactors
Alkaya, Emrah; Demirer, Göksel Niyazi (2011-03-01)
In this study, biochemical methane potential (BMP) assay was conducted to investigate the effect of waste mixing and F/M ratio on the co-digestion of wastewater and beet-pulp, in addition to the digestion of the wastes separately. In the studied F/M range (0.51–2.56 g COD/g VSS), observed treatment efficiencies (63.7–87.3% COD removal and 69.6–89.3% VS reduction) were indications of high biodegradability for both wastewater and beet-pulp, which decreased with increasing F/M. It was evident that the extent o...
Biological hydrogen production from olive mill wastewater and its applications to bioremediation
Eroğlu, Ela; Eroğlu, İnci; Department of Chemical Engineering (2006)
Hydrogen production by photosynthetic bacteria occurs under illumination in the presence of anaerobic atmosphere from the breakdown of organic substrates, which is known as photofermentation. In this study, single-stage and two-stage process development were investigated for photofermentative hydrogen production from olive mill wastewater by Rhodobacter sphaeroides O.U.001 within indoor and outdoor photobioreactors. It was proven that diluted olive mill wastewater (OMW) could be utilized for photobiological...
Oxygen-transfer strategy and its regulation effects in serine alkaline protease production by Bacillus licheniformis
Çalık, Pınar; Özdamar, Tunçer H. (2000-08-01)
The effects of oxygen transfer on the production and product distribution in serine alkaline protease (SAP) fermentation by Bacillus licheniformis and oxygen-transfer strategy in relation to the physiology of the bacilli were investigated on a defined medium with citric acid as sole carbon source in 3.5-dm(3) batch bioreactor systems. By forming a 3 x 3 matrix with the parameters air-inlet rates of Q(O)/V-R = 0.2, 0.5, 1.0 vvm, and agitation rates of N = 150, 500, 750 min(-1), the effects of oxygen transfer...
