Wool scouring effluents (WSE) were analyzed by high-resolution gas chromatography-mass spectrometry (HRGC-MS), and then exposed to anaerobic biological treatment using laboratory scale fixed-bed filters. This resulted in a nearly 50% reduction in chemical oxygen demand (COD). Ozonation of the effluent from the biological step led to an even further decrease in total organic carbon (TOC). The fatty acid content of the WSE was affected by both biological treatment and ozonation. Finally, steroids in the WSE underwent reduction reactions when exposed to the anaerobic biological treatment.

Abstract
Wool scouring effluents (WSE) were analyzed by high-resolution gas chromatography-mass spectrometry (HRGC-MS), and then exposed to anaerobic biological treatment using laboratory scale fixed-bed filters. This resulted in a nearly 50% reduction in chemical oxygen demand (COD). Ozonation of the effluent from the biological step led to an even further decrease in total organic carbon (TOC). The fatty acid content of the WSE was affected by both biological treatment and ozonation. Finally, steroids in the WSE underwent reduction reactions when exposed to the anaerobic biological treatment.
