The fate and removal of six selected endocrine disrupting compounds in a lab-scale anaerobic/aerobic (A/O) sequencing batch reactor (SBR), operating at 5 days, solids retention time (SRT) were investigated. A carbamazepine (CBZ), acetaminophen (ATP), diltiazem (DTZ), butyl benzyl phthalate (BBP), estrone and progesterone mix was spiked as model endocrine disrupting compounds (EDC) into domestic wastewater obtained from a nearby sewage treatment plant. The influent, effluent and sludge samples from the SBR unit were analysed by using an LC/MS/MS instrument equipped with electrospray ionization. More than 80% removal was observed for all the EDCs tested. It was found that biodegradation is the most important mechanism for BBP, ATP and progesterone. Biodegradation constants were calculated according to the simplified Monod model for these compounds. The DTZ seemed to have lower rate of biodegradation. The CBZ appeared totally resistant to biodegradation. However, it presented a high rate of sorption onto the sludge and was thereby treated. This contradicts with the literature studies.

Determination of Selected Endocrine Disrupter Compounds at Trace Levels in Sewage Sludge Samples
Sonmez, Munire Selcen; Muz, Melis; Komesli, Okan Tarik; BAKIRDERE, Sezgin; Gökçay, Celal Ferdi (2012-09-01)
Simultaneous determination of endocrine disrupter compounds (EDCs), namely diltiazem, progesterone, benzylbutylphthalate (BBP), estrone, and carbamazepine (Cbz) were performed by using high performance LC-electrospray tandem MS. The ultrasound-aided sequential extraction of sludge samples was optimized to increase extraction efficiencies of the analytes; ranging between 93.0-98.3% recovery. The limit of detection values for diltiazem, progesterone, BBP, estrone, and Cbz were found as 0.78, 0.72, 0.24, 0.75,...
Removal of endocrine disrupter compounds and trace organics in membrane bioreactors
Komesli, Okan Tarik; Gökçay, Celal Ferdi; Department of Environmental Engineering (2012)
Endocrine disrupters and trace organic contaminants are recently recognized contaminants in wastewaters. Current concept is the multibarier approach where the contaminants are removed from the water cycle both by water and wastewater treatment facilities, as well as natural die-away. In this thesis work LC/MS/MS determination of selected EDC compounds, namely, diltiazem, progesterone, estrone, carbamazepine, benzyl butyl phthalate and acetaminophen, at ultra trace levels, have been carried out by optimizing...
Removal of hexavalent chromium anions via polymer enhanced ultrafiltration using a fully ionized polyelectrolyte
HAKTANIR, CEREN; Ozbelge, H. Onder; Bicak, Niyazi; Yılmaz, Levent (Informa UK Limited, 2017-01-01)
A fully ionized polyelectrolyte was synthesized for Cr(VI) removal from aqueous solutions by continuous polymer enhanced ultrafiltration (PEUF). Effect of operating parameters such as pH, loading, polymer, and competing ion concentrations were examined. Highest Cr(VI) retention was obtained at a loading of 0.01 at pH 4. Increasing both polymer and chromate concentrations at a fixed loading of 0.01 decreased the retention which demonstrated the effect of crowding. In the presence of competing anions such as ...
PRODUCTION OF L(+)-LACTIC ACID USING IMMOBILIZED RHIZOPUS-ORYZAE - REACTOR PERFORMANCE-BASED ON KINETIC-MODEL AND SIMULATION
Hamamcı, Haluk (1994-02-01)
The production of L(+)-lactic acid using alginate immobilized Rhizopus oryzae in tapered-column fluidized-bed batch reactor was tested and simulated using the kinetic data taken independently in shake-flask cultures. The data show saturation kinetics with substrate and product inhibitions in linear form. Analysis of the kinetic data gave kinetic constants: V-m, 11.04 g lactic acid/(L-bead. h); K-m, 20.9 g glucose/L; and K-i, 365 g glucose/L for lactic acid production. The product inhibition constant, K-p, w...
Removal of some organic compounds and color from olive mill wastewater by electrocoagulation
Ugurlu, Mehmet; Kula, Ibrahim; Guerses, Ahmet (2006-01-01)
The effective performance of electrocoagulation (EC) technique in the treatment of olive mill wastewater (OMW) was investigated using Al and Fe electrodes. Current densities (CD), electrode materials (Al and Fe), electrolyte amounts, time and initial pH value were selected as parameters. In these parameters, the removal percentage of chemical oxygen demand (COD), color, phenol and lignin from OMW were experimentally investigated. OMW was used directly without pH adjustment and pretreatment. The experiment r...
