Development of a Sustainable Approach for Indigo Dye Removal in Textile Wastewater by a Combinative Adsorption and Catalytic Regeneration System

In this project, an integrative approach in which combined process of adsorption and ozonation are used for removing the indigo dye from textile wastewater and the regeneration of the adsorbent materials. Series of novel alumina-based adsorbents and clay-based adsorbents as efficient dye adsorbent materials for indigo dye wastewater will be developed for adsorption process and regenerated by ozonation process. This new, environmental-friendly and cost-effective approach target to achieve chemical oxygen demand (COD) removal from indigo dye wastewater at least 95% and percentage of decolourisation at least 95%.
