PERFORMANCE OF SOIL AQUIFER TREATMENT (SAT) WITH TAMARIND FRUIT SHELLS ADSORBENT TO REMOVE LEAD

In the present work, Tamarind Fruit Shell was used to enhance the removal efficiency of Soil Aquifer System (SAT) for the removal of Lead(Pb). The column studies were carried out using 3 different concentrations for Pb metal in Synthetic wastewater (5, 15, 25mg/L) and varying adsorbent heights (20%, 40%, 60%, and 80%) in 0.8m soil depth. Soil properties were determined and Loamy Sand soil was used. The efficiency of SAT to remove Pb without Tamarind Fruit Shell resulted in 38.4%, 44.5%, 43% for Pb. The conjunction of Tamarind Fruit Shell in SAT resulted in increased removal efficiency. Whereas the efficiency was observed maximum at 80% height of adsorbent resulting 82.8%, 84.4%, 75.3% for Pb. Comparison studies show that SAT in conjunction with Tamarind Fruit Shell showed better performance than without adsorbent one.
