Abstract

Increasing industrialization creates a large scale of pollution and affects the availability of usable water. Dyes in wastewater are a visible pollutant, difficult to treat, and are toxic in nature. Amongst all the physicochemical methods, adsorption is the extensively applied process for the aqueous removal of dye. In the present study; the Bagasse Fly Ash (BFA) is used as an adsorbent for aqueous removal of Acid Orange dye in packed bed adsorption technique. The packed bed studies for different bed heights, influent concentration and flow rate are performed. The efficacy of packed columns is investigated using different models namely Bed depth service time, Thomas, Wolborsaka, Yoon-Nelson, and Bohart-Adams Models. The maximum adsorption capacity of BFA for 50% saturation of column is calculated to be 38 (mg/g) which shows BFA as a good adsorbent for dye removal.
