Item Landfill leachate treatment by fenton and fenton-Like oxidation processes(Wiley, 2013-06-07) Kiril , Berna Mert; Yalılı Kılıç, Melike; Yonar, Taner Yona; Uludağ Üniversitesi/Mühendislik Fakültesi/Çevre Mühendisliği Bölümü.; 0000-0002-0387-0656; AAD-9468-2019; AAG-8505-2021; HKF-2179-2023; 55897413400; 6505923781The treatment of landfill leachate with physico-chemical and Fenton and Fenton-like processes was investigated. Additionally, the acute toxicities of the raw, the physico-chemical pre-treated, and the Fenton and Fenton-like oxidation treated leachates on activated sludge microorganisms are given (determined by the ISO 8192 (respiration inhibition test)). Pre-treatment with lime positively affected the biodegradability of the sludge by preventing inhibition. The Fenton and Fenton-like processes resulted in high chemical oxidation demand (COD) (>80%) removal performance from leachate samples. The inhibitory effects of the Fenton and Fenton-like reagents on activated sludge mixtures decreased. In addition to toxicity, the COD removal efficiencies and the operation costs of the applied processes were determined.Item Recovery of Cr(III) from tanning process using membrane separation processes(Springer, 2014-03-03) Kiril , Berna Mert; Kestioğlu, Kadir; Uludağ Üniversitesi/Mühendislik Fakültesi/Çevre Mühendisliği Bölümü.; 8910702800In chrome tanning wastewater study, a wastewater treatment alternative was decided. This treatment alternative contains cartridge filter, ultrafiltration [UF1 (20 kDa), UF2 (50 kDa), UF3 (150 kDa)], nanofiltration NF (XN45), and reverse osmosis RO (ACM2). Chrome tanning wastewater was given to the other membranes to increase the life time of the membranes after cartridge filter application. The wastewater from cartridge filter was given to 3 different UF membranes which have different pore diameters (20, 50, and 150 kDa) with 3 different pressure (6, 8, and 10 bar) in this alternative. For this treatment alternative, for 200 m(3)/G flow, 8 pieces of (273 m(2)) UF (20 kDa), 8 pieces of (160 m(2)) NF (XN45), and 12 pieces of (375 m(2)) RO (ACM2) membranes were used. The total investment for this treatment alternative was calculated as 228,415 a,not sign, and process cost was calculated as 2.77 a,not sign/m(3); however, for the classical treatment facility, investment was calculated as 345,400 a,not sign, and process cost was calculated as 0.8 a,not sign/m(3). As a result when compared to classical treatment systems, the membrane technology was found to have more economic the investment and the process costs.
