A reserach project investigated the feasibility of using ozonation to renovate spent reactive dyebath effluents and of using the decolored water for subsequent dyeings. Trials utilized ten commercial shades and performed dyeings of cotton fabrics in a tumbler dyeing machine, which was designed to collect the spent dyebath. A continuous ozone contactor accomplished the ozonation. Researchers considered the effects of temperature and pH on decolorization and studied the kinetics of color removal. The success of dyeings that used the renovated water depended on the shades being dyed and the quality of the renovated water supply. Reproducibility of dark shades was excellent for dyeings that utilized water in which 50 to 90 percent of the color had been removed by ozonation. Successful dyeings of very bright or pastel shades, however, required the use of renovated water from which 95 percent of the color had been removed. 12 refs.
