Abstract

The most important pollutant sources in the textile industry wastewater are the dyes used in the process. In this study, coagulation method with chitosan was applied for color and COD removal from dyeing wastewater. In the experimental studies, the Box Wilson statistical design method was used and the effects of dye concentration, chitosan concentration and precipitation time after coagulationflocculation on color and COD removal efficiency were investigated. The dye concentration was selected to be 50-200 mg/l, chitosan concentration 50-200 mg/l and precipitation time 30-120 minutes. The highest color removal efficiency (70%) was determined as 50 mg/l of dye concentration, 125 mg/l of chitosan concentration and 90 minutes of precipitation time. When the COD removal was examined, the highest COD removal efficiency (60%) was obtained at 200 mg/l of dye concentration, 200 mg/l of chitosan concentration and 30 minutes of precipitation time

Özet

Tekstil endüstrisi atıksularındaki en önemli kirletici kaynakları proseste kullanılan boyalardır. Bu çalışmada, boyalı sulardan renk ve KOİ giderimi amacıyla çitosan ile koagülasyon yöntemi uygulanmıştır. Deneysel çalışmalarda Box Wilson istatistiksel tasarım yöntemi kullanılmış, boya konsantrasyonu, çitosan konsantrasyonu ve koagülasyon-flokülasyon sonrası çökelme süresinin renk ve KOİ giderme verimi üzerindeki etkileri incelenmiştir. Boya konsantrasyonu 50-200 mg/l, çitosan konsantrasyonu 50-200 mg/l ve çökelme süresi 30-120 dakika aralığında seçilmiştir. En yüksek renk giderme veriminin (%70) elde edildiği boya konsantrasyonu 50 mg/l, çitosan konsantrasyonu 125 mg/l ve çökelme süresi 90 dakika olarak belirlenmiştir. KOİ giderimi incelendiğinde ise 200 mg/l boya konsantrasyonu, 200 mg/l çitosan konsantrasyonu ve 30 dakika çökelme süresinde en yüksek KOİ giderme verimi (%60) elde edilmiştir
