NATURAL ADSORBENTS; AN ECO-FRIENDLY SOLUTION FOR THE REMOVAL OF PH, TDS, DO, BOD & COLOR FROM THE TEXTILE EFFLUENT

The use of different natural adsorbents to eliminate pollutant from textile effluent was studied in this research. Several naturally abundant adsorbents have been used in this work. Two blends of adsorbents made with different natural adsorbents. Blend-1 was made of Plantain Plant bark (Banana), Stem of Water Lilies, coconut fiber/coir and Hartaki. Blend-2 was made of Plantain Plant bark (Banana), Stem of Water Hyacinth, Stalk of an edible root and Dry straw of rice. The textile effluent was prepared and treated with both blends of natural adsorbents. The retention time for both blends of adsorbents was 24 hours. The pH value of the effluent found 12.14 and after 24 hours of treatment with blend-1 found 6.21 & for blend-2 found 8.45. TDS value of the effluent found 3920 before treatment and after treatment found 3440 & 2760 for blend-1 & blend-2 respectively. The DO in the effluent found 3.2 & 2.9 after treating with blend-1 & blend-2 respectively while before treatment DO content of the effluent was 0.8. Both blends of adsorbents showed similar effect (130) on the removal of BOD, while before treatment BOD value was 190. In both case, the color of the effluent turned to brown from its raw color (Black).
