Bu çalışmada sülfat indirgeyen sabit aktif karbon yataklı bir biyofilmreaktörde (Sİ-AKYB), metal işleme sanayii klişecilik faaliyetlerinden kaynaklanan Cr+6, Cu ve Fe yüklü atıksu simüle edilerek sistem kararlılığı ve metal giderim performansı araştırılmıştır. Sülfat İndirgeyen Bakteri (SİB) ile zenginleştirilmiş Sİ-AKYB, her bir işletme fazında yeni bir ağır metal ilave edilmek suretiyle 150 mg/L Cr+6, 570 mg/L Cu ve 115 mg/L Fe konsantrasyonlarına varan metal yükleri ve 24 saatten 6 saate kadar düşürülen hidrolik bekletme süresi koşullarında test edilmiştir. Yürütülen çalışmalar, Si-AKYB’nin Cr+6 içeren ağır metal yüklü atıksuların arıtılmasında kimyasal çöktürme işlemlerine kıyasla daha çevre dostu ve maliyet etkin bir alternatif olabileceğini göstermiştir.
