Efficiency of Natural Biological Adsorbents to Remove Pollutants from Textile, Dye and Printing Industry Effluent

Adsorption is considered to be one of the most promising techniques for wastewater treatment over the last decades. The present study was conducted to treat the Textile, dye and printing industry effluents using naturally occurring biological adsorbents (Areaca catechu, Moringa pterygosperma, Quercus infectoria and Tamarindus indica). The treatment was carried out on various concentrations (of dye effluents). Highest removal of pollutant was observed at lower effluent concentrations (25% and 50%) as compared to higher effluent concentrations (75% and 100%). The reduction in pollution load may be due to the coagulative/chelative property of the adsorbents which could be used as low cost and safe bilogical adsorbents for removing toxic susbstances in Textile, dye and printing industry effluents
