Efficiency of biological leachate treatment from tobacco waste

In this study an aerobic treatment of leachate from tobacco waste using activated sludge under batch conditions was carried out. In experiments, pH value, dissolved oxygen, chemical oxygen demand (COD), and suspended solids have been monitored. Leachate treatment was conducted with different initial concentrations of leachate from 500 to 5000 mg dm-3 and initial concentrations of activated sludge from 1.84 to 6.62 g dm-3 during 96 hours. Leachate treatment efficiency was 80.0 – 99.8 % for Experiment A, 88.0 – 91.5 % for Experiment B, 87.0 – 92.0 % for Experiment C, 84.0 – 96.0 % for Experiment D, and 81.0 – 95.0 % for Experiment E in respect to initial COD concentrations.
