Purpose: The aim of this study was to investigate the removal performances of four pesticides (tributyl phosphate, flutriafol, dicofol and irgarol) by RO membranes. Methods: Three different RO membranes (BW30-LE, SW30-XLE and GE-AD) were used to reject pesticides in two transmembrane pressures of 10 and 20 bar in bench-scale membrane filtration cell. Tributyl phosphate and flutriafol were detected by GC/MS and dicofol and irgarol were monitored by HLPC instruments. Results: While the highest removal of tributyl phosphate was obtained by the BW30-LE and GE-AD membranes with 98-99%, all membranes (BW30-LE, SW30-XLE and GE-AD) rejected irgarol with around 98% performance at 10 and 20 bar pressures. Irgarol and dicofol removal performances of all the RO membranes tested were higher than 95%. Conclusion: Among the membranes tested, the BW30-LE membrane showed superior performance in the removal of all four pesticides, with removal efficiencies of 98-99%. Increasing TMP from 10 bar to 20 bar did not significantly affect pesticide removal efficiencies.

Removal of pesticides from secondary treated urban wastewater by reverse osmosis
ATEŞ, NURAY; UZAL, NİĞMET; Yetiş, Ülkü; Dilek, Filiz Bengü (2022-04-01)
The residues of pesticides that reach water resources from agricultural activities in several ways contaminate drinking water resources and threaten aquatic life. This study aimed to investigate the performance of three reverse osmosis (RO) membranes (BW30-LE, SW30-XLE, and GE-AD) in rejecting four different pesticides (tributyl phosphate, flutriafol, dicofol, and irgarol) from secondary treated urban wastewater and also to elucidate the mechanisms underlying the rejection of these pesticides. RO experiment...
Removal of imidacloprid from wastewaters by ozonation and photo-ozonation
Sönmez, Büşra; Dilek, Filiz Bengü; Department of Environmental Engineering (2019)
The widespread occurrence of micropollutants in the receiving water bodies apparently shows that conventional wastewater treatment plants (WWTP) are not capable to remove these compounds. Imidacloprid (IMI), which is a specific pollutant and an insecticide, exceeded Environmental Quality Standards (EQS) value (0.14 µg/L, annual average) in several receiving water bodies of WWTPs in Yeşilırmak basin. With the aim of examining advanced treatment methods to meet EQS value and to achieve good surface water qual...
Use of Fenton oxidation to improve the biodegradability of a pharmaceutical wastewater
Tekin, Huseyin; BİLKAY, Okan; Ataberk, Selale S.; Balta, Tolga H.; Ceribasi, I. Haluk; Sanin, Faika Dilek; Dilek, Filiz Bengü; Yetiş, Ülkü (2006-08-21)
The applicability of Fenton's oxidation to improve the biodegradability of a pharmaceutical wastewater to be treated biologically was investigated. The wastewater was originated from a factory producing a variety of pharmaceutical chemicals. Treatability studies were conducted under laboratory conditions with all chemicals (having COD varying from 900 to 7000 mg/L) produced in the factory in order to determine the operational conditions to utilize in the full-scale treatment plant. Optimum pH was determined...
Treatment of implant-related methicillin-resistant Staphylococcus aureus osteomyelitis with vancomycin-loaded VK100 silicone cement: An experimental study in rats

Introduction: The purpose of this present study is to investigate the efficacy of vancomycin-loaded VK100 silicone cement drug delivery system in the treatment of implant-related methicillin-resistant Staphylococcus aureus (MRSA) osteomyelitis in rats. Materials and Methods: Thirty-six adult (18-20 weeks old) female Sprague-Dawley rats were included in the study. All rats underwent experimental osteomyelitis surgery via injecting 100 mu L bacterial suspension of MRSA into the medullary canal. After a 2-week...
Recovery of brackish water from reactive dyeing wastewater by ultrafiltration
Erkanlı, Mert; ZAF, RUKEN DİLARA; Yılmaz, Levent; Çulfaz Emecen, Pınar Zeynep; Yetiş, Ülkü (2017-02-06)
In this study, brackish water recovery from a real reactive dyeing textile effluent for reuse of water and salt was investigated. With the aim of improving the overall retention of species that are partly retained in a single stage, three different two-stage ultrafiltration scenarios were considered: 5 kDa followed by 5 kDa, 5 kDa followed by 2 kDa and 2 kDa followed by 2 kDa. The 2 kDa + 2 kDa scenario reduced the total organic carbon (TOC) from 239 +/- 9 mg/L to 41 +/- 7 mg/L, at 2 bar of transmembrane pr...
