Feasibility of industrial scale treatment of dye wastewater via bio adsorption technology.
This review emphasizes the importance of costs in industrial scale treatment of dye wastewater and provides a way to assess the cost based feasibility of bio adsorption technologies. Dye wastewater is one of the major contributors to environmental pollution. Bio adsorption has attracted considerable attentions in dye wastewater treatment due to its technical feasibility, flexibility and operation simplicity. However, industrial scale treatment of dye wastewater via bio adsorption technologies remains stagnant, mainly due to high costs. So far, no review or research articles have systematically discussed the criteria for successful utilization of bio adsorption technologies on a large scale. This review discusses the major factors affecting adsorption and desorption performance based on basic chemical and physical structures of bio adsorbents available in literatures. A quantitative relationship has been summarized based on previous studies to assess the cost to utilize a bio adsorption technology and serve as an access threshold for quality bio adsorbents to be taken into real applications.
