 Colours make the world more beautiful and happier, but the discharge of coloured wastewaters turns the world ugly and saddens the environment. The release of coloured wastewaters into surface water is undesirable not only because of their aesthetic appearance and the impact of dyes on photosynthesis of aquatic plants, but also because many of these dyes and their breakdown products are carcinogenic. Without adequate removal, dyes may persist for decades in the environment, thus representing a big challenge for environmental engineers in the design of an efficient and economical attractive treatment. The overall objective of this research was to develop novel treatment strategies in anaerobic bioreactors for coloured wastewaters by using thermophilic anaerobic granular sludge and redox mediators such as flavin-based vitamins and quinones containing-humus. This aimed to include the cost-effective anaerobic technology as a pre-treatment for coloured wastewaters from textile, chemical and pharmaceutical industries, in closing process water cycles.
