Sažetak
Treatment of tobacco dust leachate represents an important problem because of high concentrations of organic compounds. Experiments were carried out in a batch reactor at initial concentrations of activated sludge of 3.1 and 6.0 g dm-3 and different initial concentrations of organic matter in leachate, expressed as COD concentrations, which were in range from 500 to 5000 mg dm-3. Efficiency of biodegradation process was approximately 89.4 %. The kinetic parameters μmax, Ks and Y during experiments were found to be 0.088 h-1, 4241 mg dm-3, and 0.400 mg mg-1 for Exp. 1 ; and 0.052 h-1, 3168 mg dm-3, and 0.257 mg mg-1 for Exp. 2, respectively. This model gives very good fits to experimental data, accompanied by a high regression coefficient (R2).
