Other researchers have examined the combination UV/H2O2 processes in the decolourisation of textile wastewater and dyebath effluent e.g., [13–16]. Wang et al. [17] investigated
the removal of dissolved organic matter from biologically treated water by UV/H2O2, while Ahn et al. [18] and Park et al. [19] studied the optimum dose of H2O2 for the removal of colour.
