TEKSTİL ATIKSUYU VE SENTETİK BOYARMADDE ÇÖZELTİLERİNDEN RENK VE KOİ GİDERİMİNDE ALÜM VE MAGNEZYUM KLORÜRÜN KARŞILAŞTIRILMASI
Öz
Bu çalışmada Adana
ilinde faaliyet gösteren iki farklı tekstil endüstrisi atıksuyu ve Basic Blue
41, Basic Blue 3, Vat Green 1, Vat Blue 4, Direct Blue 71 ve Reactive Blue 29
boyarmaddelerini içeren sentetik olarak hazırlanmış çözeltilerde magnezyum flokülasyonunu
çalışılarak geleneksel bir koagülant olan alüm ile karşılaştırılmıştır. Her iki
koagülant için optimum doz çalışılmış olup magnezyum flokülasyonunda pH’ın
etkisi araştırılmıştır. Magnezyum flokülasyonunda 11,5 pH değerinde daha etkili
sonuç alındığı gözlenmiştir. Renk ve KOİ gideriminde ise magnezyum
flokülasyonunun alümden daha etkili olduğu tespit edilmiştir. Ayrıca deneysel
çalışma verileri Freundlich, Langmuir, Temkin ve Dubinin-Radushkevich
adsorpsiyon izoterme modeline adsorpsiyon uyumunu tespit etmek için uygulanmış
ve model sabitleri hesaplanmıştır. Modelleme çalışması sonucunda Renk ve KOİ
gideriminde adsorpsiyonun da önemli etkisinin olduğu tespit edilmiştir.

COMPARISON OF ALUM AND MAGNESIUM CHLORIDE IN COLOR AND COD REMOVAL FROM TEXTILE INDUSTRY WASTEWATER AND SYNTHETIC DYEING SOLUTIONS
Öz
In this study, magnesium flocculation of textile
industry effluents from two factories and synthetic dyes solutions containing
Basic Blue 41 (BB41), Basic Blue 3 (BB3), Vat Green 1 (VG1), Vat Blue 4 (VB4),
Direct Blue 71 (DB71), and Reactive Blue 29 (RB29) have been studied and the
results were compared with alum as conventional coagulant. The effects of pH on
magnesium flocculation and optimum dosages for each coagulants have also been
investigated. The results showed that pH 11,5 was the most efficient for
magnesium flocculation. The color and COD removal efficiencies of magnesium
flocculation were found better than those of alum. The data from experimental
studies were also applied to Freundlich, Langmuir, Temkin, and
Dubinin-Radushkevich adsorption isotherm models and related constants of each
model were also calculated in order to determine the effect of adsorption. It
was found out that the adsorption played an important role during whole
coagulation process for the removal of color and COD
