Aerobic treatment of leachate from tobacco waste
This research was initiated to characterize the biodegradability of leachate from composting tobacco waste. Leachate that originated from tobacco waste has high concentrations of chemical oxygen demand (COD). Experiments were conducted in a batch reactor with different initial concentrations of leachate (500, 1000, and 1500 mg dm-3), and initial concentration of activated sludge (5.8 g dm-3) during of 48 hours. The results of the mixed liquor suspended solids (MLSS) concentrations were between 6.38 g dm-3 - 6.74 g dm-3. The ratio of MLVSS/MLSS was in the range 0.69–0.70. The pH values and dissolved oxygen (DO) were about 7.02 and between 5.90 to 5.44 g dm-3. The COD was reduced by 62 % and resulted to 13.9 % increase in MLSS. The feed to microorganism (F/M) ratio varied from 0.29 to 0.49 g COD (g MLSS) -1 d-1. The specific oxygen uptake rate, SOUR varied between 0.16 and 1.31 mg O2 (g MLVSS)-1 d-1. Mean floc size increased by about 24 % within the first 24 h.
