Abstract

Bu çalışmada, maya endüstrisi atıksuyunun renk ve kimyasal oksijen ihtiyacı (KOİ) giderimi için ultrases kullanılmıştır. Bu amaçla 20kHz frekansta ultrasonik homojenizatör kullanılmıştır. Ultrasonik güç, vuruş döngüsü, atıksu hacmi, seyreltme oranı (atıksu hacmi/distile su hacmi) gibi parametreler incelenmiştir. Renk gideriminin ultrasonik güç artarken ve atıksu hacmi azalırken arttığı gözlenmiştir. Sonuçlar maya endüstrisi atıksuyunun renk gideriminde vuruş döngüsünün önemli etkisinin olmadığını göstermiştir. Renk gideriminde optimum seyreltme oranı ¼’dür. Çalışılan koşullarda KOİ değerlerinde değişiklik olmamıştır.

Effect of operational parameters on ultrasonic treatment of baker’s yeast effluent

Abstract

In this study, ultrasound was employed to remove color and chemical oxygen demand (COD) from baker’s yeast effluent. An ultrasonic homogenizator with 20kHz frequency was used for this purpose. The effect of operational parameters such as ultrasonic power, pulsed cycle, volume of wastewater and dilution ratio (wastewater volume/distilled water volume) was investigated. It was observed that decolorization increased with increasing ultrasonic power and with decreasing wastewater volume.  The results show that there was no significant effect of pulsed cycle and an optimum dilution ratio was ¼ on decolorization of baker’s yeast effluent. There was no change on COD value at the studied conditions.
