Abstract

Bu çalışmada, Balıkesir ilinde faaliyet gösteren bir zeytinyağı üretim tesisinden temin edilen zeytin karasuyunun arıtımında ozon (O3), ozon+hidrojen peroksit (O3+H2O2) ve fenton (Fe2++H2O2) proseslerinin etkinlikleri incelenmiştir. İlk olarak %10 kapasite ile O3 jeneratörü çalıştırılmış ve 3 farklı pH (4.75, 10 ve 11) değerinde 6 saat boyunca ozonlama işlemi gerçekleştirilmiş ve maksimum giderim verimi pH değeri 11 olarak ayarlandığında %15.27 olarak hesaplanmıştır. İkinci olarak %10 kapasite ile O3 jeneratörü çalıştırılmış ve ortama 500 mg L-1 H2O2 ilave edilmiştir. 6 saatlik bu deneme sonrasında giderim verimi %9.8 olarak gerçekleşmiştir. Son olarak zeytin karasuyunun arıtımı için farklı Fe2+ (2.014 g L-1 ve 4.028 g L-1) ve H2O2 (19.05, 44.44 ve 80 g L-1) konsantrasyonlarının etkilerinin incelendiği fenton prosesinde Fe2+ ve H2O2 konsantrasyonları arttığında deney sonunda ortamda kalan KOİ konsantrasyonları sürekli azalmıştır. Fe2+ konsantrasyonu 4.029 mg L-1 ve H2O2 konsantrasyonu 80 mg L-1 olarak ayarlanmış ve %81.94 oranında KOİ giderimi sağlanmıştır. Elde edilen sonuçlar fenton prosesinin, diğer proseslerden çok daha fazla etkinliğinin olduğunu ortaya çıkarmıştır.

Investigation of Olive Mill Wastewater Treatment with Advanced Oxidation Processes

Abstract

In this study, the effectiveness of ozone (O3), ozone+hydrogen peroxide (O3+H2O2) and fenton (Fe2++H2O2) processes were investigated in the treatment of olive mill wastewater obtained from an olive oil production facility operating in Balıkesir province. Firstly, the ozone generator was operated with a 10% capacity. Ozonation was performed for 6 hours at three different pH values (4.75, 10 and 11) and the maximum removal efficiency was calculated as 15.27% when the pH value was 11. Secondly, the ozone generator was operated with a 10% capacity and an avarage of 500 mg L-1 H2O2 was added. After this 6 hour experiment, the removal efficiency was obtained as 9.8%. Finally, in the fenton process, where the effects of Fe2+ (2.014 g L-1 and 4.028 g L-1) and H2O2 (19.05, 44.44 and 80 g L-1) concentrations were examined for the treatment of olive mill wastewater, the remained concentrations of COD decreased continuously at the and of the experinent when Fe2+ and H2O2 concentrations increased. The concentrations of Fe2+ and the H2O2 were set at 4.029 mg L-1 and 80 mg L-1 respectively, and COD removal was achieved at the rate of 81.94%. The results obtained from the experiments revealed that the fenton process has much more effeciency than other processes.
