Complete decolorization of the dark brown wastewater of the yeast-prod
uction industry is faced with problems. Biological treatments, aerobic
or anaerobic, can never ensure colorless effluent; thus, some additio
nal decolorization process is usually needed. The application of ozone
, as a final decolorization step, seems to be promising.
