“…Results show that Fe sacrificial electrodes are more cost-effective than Al electrodes, with total operating costs between 0.30 and 0.40 $/m 3 , nearly 50% of the total costs of using Al. Similar results were obtained by Ozyonar and Karagozoglu (2014), when calculating total costs for Al and Fe sacrificial electrodes at optimum conditions. Al electrodes were found less cost-effective than Fe electrodes with total costs of 2.76 and 0.87 $/m 3 , respectively.…”

“…Thus, the EC process involves onsite generation of M 3þ ions using sacrificial anodes. Additionally, these sacrificial electrodes might be interacting with H þ ions in an acidic medium, or with OH À ions in an alkaline medium Kobya et al, 2006;Bayar et al, 2011Bayar et al, , 2014Ozyonar and Karagozoglu, 2014). Kobya et al (2006) studied the influence of pH, operating time, electrode material, and current density of the EC process for SWW treatment on oilegrease and COD removal, sacrificial electrode and electrical energy consumption.…”

“…The results are shown in Figs. 11-16, As these figures show, increasing the coagulant concentration results in a reduction of pollution indices such as TSS, turbidity, and COD and increase of the TDS and EC [35]. It was also concluded that the trend of pollution indices for the concentrations more than 110 mg L -1 is slowly, therefore, with respect to consume coagulants; 110 mg L -1 can be selected as the optimal concentration.…”

Meat processing industries consume a lot of fresh water in the slaughterhouses and livestock industries worldwide. Currently, some slaughterhouses produce large amounts of harmful wastewater, because of the slaughtering process and cleaning of equipment. In this paper, an anaerobic and coagulation-flocculation hybrid process was explored in laboratory pilot scale for removal of contaminants from a slaughterhouse effluent. The findings indicated that anaerobic treatment as the first step caused a reduction of the portion of (COD), (TSS), and turbidity. Furthermore, it was concluded that coagulation-flocculation could reduce most of the suspended and colloidal particle with an aluminum sulfate dose of 110 mg l-1. (TSS), turbidity, (COD), (TDS) and (EC) have been reduced up to 71%, 41%, 76%, 49%, and 52%, respectively. Results show coagulation-flocculation can reduce most of the suspended and colloidal particles, and aluminum sulfate compare with ferric chloride and calcium oxide is a suitable coagulant for this special wastewater. On the other hand, adding coagulant generates various ions and causes an increase in TDS and EC. So, the optimal dose of aluminum sulfate was determined. Also results show that TDS and EC increased slightly after the coagulation-flocculation process compared with the anaerobic process which was due to the addition of coagulants to wastewater. Finally, the anaerobic and coagulation-flocculation hybrid process does not meet environmental standards to dispose of wastewater and requires a supplementary treatment process.

“…EC prosesi bütün bu avantajları sebebiyle farklı karakteristiklerde pek çok evsel ve endüstriyel atıksuyun arıtımında başarıyla uygulanmıştır [21][22][23][24]. Ayrıca, bu çalışmanın kapsamı olan bira endüstrisi atıksularına benzer tarım ve gıda endüstrilerinin atık sularının arıtılması için de EC prosesi tercih edilmiştir [25][26][27][28][29][30]. Ancak, bira/mayalama prosesi atıksularının arıtılması konusunda EC ile ilgili nispeten az sayıda çalışma bulunmaktadır.…”

ÖzBu çalışmada bir bira fabrikasına ait atıksuyun arıtımında anot ve katotu farklı metallerden oluşturulmuş elektrokoagülasyon (EC) yöntemi kullanılarak prosesin arıtma performansı ve işletme maliyeti analiz edilmiştir. Kesikli işletilen bir EC tankı içerisine demir (Fe) ve alüminyum (Al) elektrotlar sekiz farklı anot-katot-anot-katot (A-C-A-C) kombinasyonunda () dizilerek, prosesin atıksudan KOİ ve bulanıklık giderme verimleri ile işletme maliyetleri üzerine pH, akım yoğunluğu ve elektroliz süresinin etkileri incelenmiştir. Çalışma sonunda optimum olarak bulunan EC şartlarında (pH 7, akım yoğunluğu: 60 A/m 2 ve elektroliz süresi: 30 dak.) KOİ ve bulanıklık giderme verimleri demir elektrotlar (Fe-Fe-Fe-Fe) kullanıldığında sırasıyla %80 ve %92 olurken, demiralüminyum hibrit bağlantılı (Fe-Al-Fe-Al) EC reaktöründe ise %91 ve %97 olarak gerçekleşmiştir. Bir metreküp bira endüstrisi atıksuyunun seçilen optimum şartlar altında EC ile arıtımının işletme maliyeti ~35 TL olarak bulunurken, bir kg KOİ gideriminin maliyeti ise ~12 TL olarak hesaplanmıştır. Çıkış suyu karakteristikleri dikkate alındığında, gelecekteki çalışmalarda hibrit elektrot bağlantılı EC sisteminin benzer nitelikteki endüstriyel atıksular için bir ön arıtma yöntemi olarak kullanılabileceği ve yüksek KOİ konsantrasyonlarını bertaraf edebilecek bir anaerobik proses ile desteklenebileceği veya bir oksidasyon prosesini takiben, çıkış suyunu iyileştirme amacıyla son arıtma olarak değerlendirilebileceği sonucuna varılmıştır.Anahtar Kelimeler: Elektrokoagülasyon, Bira endüstrisi atıksuları, elektrot materyali, hibrit bağlantı şekli, kimyasal oksijen ihtiyacı, bulanıklık, işletme maliyeti AbstractIn this study, an EC process composed of the different anode and cathode materials was used for the treatment of brewery wastewater and the treatment performance and operating cost were analyzed. Iron (Fe) and aluminum (Al) electrodes are arranged in eight different anode-cathode-anode-cathode (A-C-A-C) combinations () and the effects of pH, current density and electrolysis time on COD and turbidity removal efficiencies and operating costs were investigated. At the end of the study, at the optimum EC conditions (pH 7, current density: 60 A/m 2 and electrolysis time: 30 min) COD and turbidity removal efficiencies were 80% and 92%, respectively, for iron electrodes (Fe-Fe-Fe-Fe) and 91% and 97% for EC reactor with iron-aluminum hybrid (Fe-Al-Fe-Al) electrodes. The operating cost of one cubic meter of beer industry wastewater treatment with EC under the optimum conditions was calculated as ~ 35 TL and the cost of one kg COD removal was calculated as ~ 12 TL. Considering the effluent characteristics, in future studies it can be concluded that the hybrid electrode-EC system can be used as a pre-treatment method for similar industrial wastewaters and can be integrated with an anaerobic process that can reduce high COD concentrations or can be considered as the final treatment for the treatment of effluent following an oxidation process.
