Abstract |
|
The study for removal of organic pollutants from tannery effluents was carried out in batch process using activated coconut shell mixed with laterite. The parameters included contact time, adsorbent dosage and pH. The optimum dosage for the study obtained was 100g/L, with optimum contact time of 60 min. The optimum dosage and time had greater impact on removal of pollutants like COD (86.41%), Turbidity (92.3%), TDS (95.89%) and TC (93.8%). Study on variation in pH was also carried out, where the pH from 2 to 8 was studied, in which at acidic pH i.e. at pH 2, the amount of removal of pollutants was higher i.e. it exhibited 87.92% COD, 97% removal of Turbidity, 95% removal of TDS and 93.3% of TC. As the pH decreased, the removal efficiency increased and decreased gradually by increasing the pH. |
