摘要：The study was conducted to treat the textile, dye and printing industry effluent usingnatural occurring biological adsorbents (Areaca catechu, Moringa pterygosperma,Quercus infectoria and Tamarindus indica). The treatment was carried out on variousconcentrations (25%, 50% 75% and 100%) of dye effluent. Highest removal of pollutantwas observed at lower effluent concentrations (25% and 50%) as compared to highereffluent concentrations (75 % and 100%). The addition of biological adsorbents hasbrought significant reduction in various parameters of textile, dye and printing industryeffluent. The reduction in pollution load may be due to the coagulative and chelativeproperty of Areaca catechu, Moringa pterygosperma, Quercus infectoria andTamarindus indica, which can be used as low cost and safe biological adsorbents forremoving toxic substances in textile, dye and printing industry effluent.
