Abstract
An integrative approach combines a process of adsorption and ozonation which are used for removing the indigo dye from textile wastewater and the regeneration of adsorbent materials. Metal oxide modified adsorbents are efficient dye adsorbent materials for indigo dye wastewater and are used have been developed for adsorption process and regenerated by ozonation process. Upon the regeneration process, the adsorption capacity has been recovered. The synergistic effect of adsorption and ozonation benefit for the efficient dye removal from wastewater and the adsorbent regeneration achieved in an environmentally friendly and cost effective way.
