Özet:

 Electrochemical wastewater treatment methods are effectively used for all type of wastewaters and pollutants. One of the huge negative impact of these processes is the energy consumption of the process. Therefore, the goal of the study is to develop a minimal energy user Electrocoagulation EC option with an integration of a direct photovoltaic solar panel as a subsection of electrochemical processes for the degradation of low COD Chemical Oxygen Demand from metal cutting wastewater. To optimize the operating parameters of the EC process such as pH, current density C.D. and electrolysis time E.T. Box-Behnken Design by RSM was used with a double criterial optimization option. COD removal and energy consumption were evaluated as responses of the model and they were well-fitted with the quadratic model. Also, it was determined that all parameters are effective on EC process. Optimum conditions were found at a pH of 7.48, a C.D. of 30 Am2, an E.T. of 65 min, an energy consumption of 3.9 kWhm3 and a desirability of 0.954. At the optimum conditions, the energy consumption of the EC process was fulfilled from solar panel in a ratio of 71 and 1495 in overcast and sunny weather, respectively. Especially, the energy obtained by the solar panel in the sunny weather produces much more than the energy required of the process.

 Elektrokimyasal atıksu arıtma yöntemleri her türlü atıksu ve kirletici için etkin bir şekilde kullanılmaktadır. Bu proseslerin en büyük olumsuz etkilerinden biri prosesin enerji tüketimidir. Bu nedenle, çalışmanın amacı, metal kesme atıksuyundan KOİnin ayrıştırılması için elektrokimyasal proseslerin bir alt bölümü olarak doğrudan fotovoltaik güneş paneli entegrasyonu ile minimum enerji kullanan bir Elektrokoagülasyon EK seçeneği geliştirmek olarak belirlenmiştir. EC prosesinin pH, akım yoğunluğu A.Y. ve elektroliz süresi E.S. gibi işletme parametrelerini optimize etmek için çift kriterli optimizasyon seçeneği ile RSM ile Box-Behnken Tasarımı kullanılmıştır. KOİ giderimi ve enerji tüketimi modelin yanıtları olarak değerlendirilmiş ve kuadratik model ile iyi uyum göstermişlerdir. Ayrıca, tüm parametrelerin EC prosesi üzerinde etkili olduğu belirlenmiştir. Optimum koşullar pH 7,48, A.Y. 30 Am2, E.S. 65 dakika, enerji tüketimi 3,9 kWhm3 ve arzu edilebilirlik 0,954 olarak bulunmuştur. Optimum koşullarda, EK sürecinin enerji tüketimi kapalı ve güneşli havalarda sırasıyla 71 ve 1495 oranında güneş panelinden karşılanmıştır. Özellikle güneşli havada güneş panelinden elde edilen enerji, proses için gerekli olan enerjiden çok daha fazlasını üretmektedir.
