The
yeast production industry wastewaters contains high amount of chemical oxygen
demand (COD), brownish color and recalcitrant organic components. In this work,
one of the yeast production plant wastewaters operating in the Aegean Region,
the color removal were studied with using Photo-Fenton (H₂O₂/Fe(II)/UV)
oxidation processes. In this study, the Box–Wilson statistical experimental
design method applied to optimization of decolorisation of the yeast production
industry wastewater. For this reason, the initial oxidant and catalyst
concentrations and pH of water were chosen as the experimental parameters on decolorisation.
Color removal was observed during the experimental studies. Complete color
removal (E=100%) was achieved with the addition of 2400 mg/L H₂O₂
and 121 mg/L Fe(II) at 3.7 pH after 120 min. of exposure to the UV irradiation.

Maya endüstrisi atıksularından foto-fenton yöntemi ile renk giderimi

Öz

Maya üretim endüstrisinin atığı, yüksek miktarda
kimyasal oksijen ihtiyacı (KOİ), azot, koyu renk ve biyolojik olarak
parçalanmayan organik bileşikler içermektedir. Bu çalışmada, Ege Bölgesi’nde
faaliyet gösteren bir maya sanayinin atıksularının, renk giderimi Foto-Fenton
(H₂O₂/Fe (II)/UV) oksidasyon yöntemi kullanılarak
arıtılmaya çalışılmıştır. Box-Wilson istatistiksel deneysel tasarım yöntemi kullanılarak
başlangıç oksidan ve katalizör konsantrasyonları ve suyun pH'sı gibi bazı
çalışma parametrelerinin renk giderme üzerindeki etkileri araştırılmıştır.
Çalışma süresince renk giderimi izlenmiş ve komple renk giderimi (E=%100) 120 dk.
sonra, 3.7 pH'da

2400 mg/L H₂O₂ ve 121 mg/L Fe (II) ilavesinin olduğu UV
oksidasyonu işlemi sonucunda elde edilmiştir.
