Kimyasal Spreyleme Atıksuyunun Arıtımında Elektrokoagülasyon Prosesinin Optimizasyonu: Box-Behnken Dizaynı
Abstract
Bu
çalışmada, kot pantolon üretiminde kimyasal spreyleme işleminden oluşan
atıksuyun, Alüminyum (Al) elektrot kullanılarak Elektrokoagülasyon (EK) Prosesi
ile arıtımı incelenmiştir. EK
prosesi ile KOİ (Kimyasal Oksijen İhtiyacı) ve TÇK (Toplam Çözünmüş Katı)
parametrelerinin giderimi için pH, akım yoğunluğu (A.Y.) ve elektroliz süresi
(E.S.) gibi EK proses verimliliğinde önemli rol oynayan parametrelerin etkileri
belirlenmiştir. Deneysel tasarımda Box-Behnken istatistiksel modeli kullanılmıştır.
İstatistiksel analizler her iki kirletici için de sonuçların quadratik modele
uygun olduğunu göstermiştir. EK reaktöründe KOİ ve
TÇK'nın giderilmesi için regrasyon (R2) değerinin sırasıyla 0,95 ve
0,99; R2adj değerinin sırasıyla 0,88 ve 0,99 olduğu
bulunmuştur. R2 ve R2adj
değerlerinin 1'e yakın olması, deney sonuçlarının ve istatistiksel
çıkarımların uyumlu olduğunu ve işlem parametrelerinin etkilerinin
belirlenmesinde Box-Behnken istatistiksel tasarımının etkili olduğunu
göstermektedir. KOİ ve TÇK giderimi için optimum pH değerleri sırasıyla
5,01 ve 6,66 olarak tespit edilirken, her iki kirletici için optimum akım
yoğunluğu 59 A / m2 ve elektroliz süresi 29 dk. olarak belirlenmiştir.
