    Treatment of olive mill wastewater by combined process of coagulation, fenton oxidation and adsorption process
    (Parlar Scientific Publications (P S P), 2021-01-01) Kılıç, Melike Yalılı; YALILI KILIÇ, MELİKE; Bursa Uludağ Üniversitesi/Mühendislik Fakültesi/Çevre Mühendisliği Bölümü.
    In this study, the treatability results of olive mill wastewater (OMW) using acid cracking, coagulation, Fenton oxidation and adsorption processes are presented. Various coagulants, such as alum and ferric chloride were used in coagulation experiments. The effect of coagulants, iron-salt, and hydrogen peroxide dosages, and activated carbon concentration on treatment efficiency was evaluated, and optimal conditions were established. Acid cracking and coagulation showed high efficiency of chemical oxygen demand (COD) (73%), phenol (84%), and suspended solid (SS) (90%) removal from the OMW. As a result of this study, the COD reduction increased to 95% though when acid cracking and coagulation were coupled with Fenton.

    A comparative treatability study for textile wastewater: Agricultural waste adsorbent versus activated carbon
    (Hard, 2020-01-01) Kılıç, Melike Yalılı; YALILI KILIÇ, MELİKE; Bursa Uludağ Üniversitesi/Mühendislik Fakültesi/Çevre Mühendisliği Bölümü; 0000-0001-7050-6742; AAG-8505-2021
    This study aimed to remove color from textile wastewater taken from a common effluent channel in Bursa, western Turkey. For this purpose, chemical coagulation with various coagulants including Al-2(SO4)center dot 18H(2)O, FeCl3 center dot 6H(2)O and FeSO4 center dot 7H(2)O was applied, followed by adsorption processes. In the coagulation experiments, the maximum color removal efficiency (48%) was obtained at pH 6.5 with a 300 mg/L dose of Al-2(SO4)(3)center dot 18H(2)O. The adsorption experiments were conducted using 5 g each of agricultural waste adsorbent (corncob) particles with dimensions of 0.25 mm, 0.50 mm, 0.85 mm and 1.25 mm on the chemically treated wastewater samples, and color removal efficiencies of up to 100% were obtained. In addition, adsorption columns were designed according to the experimental data. As a result of the design calculations, 84 tons of the corncob are required to effectively remove color from 10,000 m(3) of textile wastewater. In addition to the color removal efficiencies of the applied processes, the associated operating costs were also calculated.
