Abstract (2. Language): 
This study, it was aimed to investigate the treatment of slaughterhouse wastewater by chemical coagulation-floculation process. For this purpose, wastewater samples were provided from a slaughterhouse in Sivas City and the effect of initial pH and coagulant dosage on COD, oil-grease and turbidity removal efficiency were investigated for three different coagulants (Al2(SO4)3.18H2O, Fe2(SO4)3.7H2O, FeCl3.6H2O). The optimum operation conditions of coagulation process were determined. This conditions, optimum pH and coagulant dosage for both Al2(SO4)3.18H2O and Fe2(SO4)3.7H2O were pH 7 and 200 mgMe3+/l. Moreover optimum operation conditions for FeCl3.6H2O were pH 6 and 100 mgMe3+/l coagulant dosage. At the optimum operation conditions, COD, oil-grease and turbidity removal efficiencies were 36.4%, 93.6%, 89.8% for Al2(SO4)3.18H2O and 27.6%, 88.6%, 85.9% for Fe2(SO4)3.7H2O respectively. The max. COD removal efficiency with FeCl3.6H2O (37.4%) was obtained. Oil-grease and turbidity removal efficiencies of FeCl3.6H2O were 89.9% and 75.6% respectively. Furthermore, sludge production and economical and technical aspects of the three coagulants were also compared. The higher sludge production with Fe2(SO4)3.7H2O (3.28 kg/m3) was obtained. Operation cots for Al2(SO4)3.18H2O, Fe2(SO4)3.7H2O and FeCl3.6H2O were calculated to be 0.527-0.233-0.265 $/m3 respectively.

Bu çalıĢmada, mezbaha endüstrisi atıksularının ön arıtımında kimyasal koagülasyon ve flokülasyon prosesi ile arıtılabilirliğinin araĢtırılması amaçlanmıĢtır. Bu amaçla, Sivas (Turkiye) ilinde faaliyet gösteren bir mezbahane endüstrisinden atıksu numuneleri alınmıĢ ve 3 farklı türde koagülan maddenin (Al2(SO4)3.18H2O, Fe2(SO4)3.7H2O, FeCl3.6H2O) kullanıldığı koagülasyon deneylerinde baĢlangıç pH‟ın ve koagülan madde dozajının; KOI, yağ-gres ve bulanıklık giderme verimi üzerine etkisi araĢtırılmıĢtır. Koagülasyon prosesinin optimum iĢletme koĢulları belirlenmiĢtir. Bu koĢullar; hem Al2(SO4)3.18H2O hem de Fe2(SO4)3.7H2O için pH 7 ve koagülan dozu 200 mgMe+3/l olarak bulunmuĢtur. Bununla birlikte FeCl3.6H2O için optimum iĢletme koĢulları pH 6 ve koagülan dozu 100 mgMe+3/l „dir. Bu iĢletme koĢullarında, alüminyum sülfat ve demir sülfat koagülan maddelerinin kullanıldığı koagülasyon deneylerinde, KOI, yağ-gres ve bulanıklık giderme verimleri, sırasıyla %36,4, %93,6 ve %89,8. (Al2(SO4)3.18H2O) ve %27,6, %88,6 ve %85,9‟dir (Fe2(SO4)3.7H2O). En yüksek KOI giderme verimi %37,4 ile demir (III) klorür koagülan maddesiyle (FeCl3.6H2O) elde edilmiĢtir. Bu koagülan maddenin kullanılmasıyla yağ-gres ve bulanıklık giderme verimleri ise sırasıyla, %89,9 ve %75,6 olarak bulunmuĢtur. Ayrıca üç koagülan maddenin çamur oluĢumu, teknik ve ekonomik açıdan karĢılaĢtırılması da yapılmıĢtır. En yüksek çamur oluĢumu Fe2(SO4)3.7H2O (3.28 kg/m3) ile elde edilmiĢtir. Al2(SO4)3.18H2O, Fe2(SO4)3.7H2O and FeCl3.6H2O için iĢletme maliyetleri sırasıyla 0,567- 0,233-0,265 $/m3 olarak hesaplanmıĢtır.
