Bu çalışmada alüminyum elektrotun farklı bağlanma şekilleri
kullanılarak elektrokoagülasyon yöntemi ile çamaşırhane atıksuyunun
arıtımı incelenmiştir. Çamaşır yıkama suları belirli oranlarda (ön
yıkama, ana yıkama ve durulama sonrası atıksular 1:1:1,5 oranında)
karıştırılarak atıksuyun karakterizasyonu yapılmıştır. Anot ve katot
olarak kullanılan alüminyum elektrotun farklı bağlanma şekillerinde,
monopolar paralel (MP-P), monopolar seri (MP-S) ve bipolar paralel
(BP-P) ile arıtım gerçekleştirilmiştir. Her bir bağlanma şekillerinde pH,
akım yoğunluğu ve süre gibi proses değişkenlerinin MBAS, KOİ ve
bulanıklık giderimi üzerine etkileri incelenmiştir. Yapılan denemelerde
maksimum giderim verimi KOİ, MBAS, bulanıklık için sırasıyla; %80,
%97, %97 değerleri ile MP-P bağlanma şeklinde pH 5.5 değerinde 15 dk.
süre ve 5 mA/cm2 akım yoğunluğunda elde edilmiştir. Monopolar
paralel bağlantı şekli ile çalışılan sistemde optimum giderim koşulları
pH 5.5, süre 15 dk. akım yoğunluğu 5 mA/cm2
, sıcaklık 25 ○C ve
karıştırma hızı 200 rpm bulunmuştur. Optimum giderim verimleri ise
MBAS, KOİ, bulanıklık için sırasıyla; %97, %80, %96 değerleri tespit
edilmiştir.

Application of various aluminum electrode connection methods to laundry wastewater via electrocoagulation

Öz

In this work, various bonding techniques for the aluminum electrode
were used to explore the electrocoagulation method for treating
laundry wastewater. By combining the laundry water in specific ratios
(1:1:1,5 ratio of the wastewater after prewash, main wash, and rinsing),
the wastewater was characterized. Aluminum electrodes were
employed as the anode and cathode, and purification was conducted
using monopolar parallel (MP-P), monopolar series (MP-S), and bipolar
parallel (BP-P) in various connection configurations. For each bonding
form, the impacts of process variables like pH, current density, and time
on COD, MBAS, and turbidity removal were examined. In the
experiments, the maximum removal efficiencies for COD, MBAS, and
turbidity, respectively, were obtained in the form of MP-P binding, at pH
5.5 for 15 minutes and at a current density of 5 mA/cm2
. The
corresponding values were 80%, 97%, and 97%, respectively. The
optimum removal conditions in the system examined with a monopolar
parallel connection were pH 5.5, duration 15 minutes, current density 5
mA/cm2
, temperature 25 ○C and stirring speed 200 rpm. The optimal
removal efficiencies for MBAS, COD, and turbidity were determined to
be 97%, 80%, and 96%, respectively.
