| Summary, etc. | Experiments on ABR were conducted to investigate its efficiency on organic carbon removal. Laboratory scale ABR units, made of PVC with dimensions of 0.25 x 0.15 x 0.32 m3 (width x depth x length), were used to treat the dissolved air flotation pre-treated slaughterhouse wastewater whose COD concentrations were 480 - 730 mg/L. The steady state performance was evaluated under organic loading rates (OLR) from 0.67 to 4.73 g COD/(L.d) and hydraulic retention time (HRT) of 2.5 to 26 h. The ABR was started up at an OLR of 0.67 g COD/(L.d) and at HRT of 26 h at ambient temperature (30 to 35' C during day time and 25 to 30' C during night time). The ABR unit was found to perform satisfactorily when operating from low OLR of 0.67 g COD/(L.d) up to 4.73 g COD/(L.d) at HRT of 2.5 h, in which the treatment efficiency of 75% was reached on a total COD basis and of 84% on a filtered COD basis. Based on COD mass balance in the ABR unit, sludge accumulation factor (Xacc) was in the range of 0.16 to 0.39 g VSS/g CODrcmovcd{u2022} and the conversion of COD removed into methane was in the range of 0.44 to 0.78 g CH4-COD/g CODrcmovcd· The sludge activities varied in the range of 0.066 to 0.293 kg CH4-COD/(kg VSS.d). Biagas produced contained 20 to 27% nitrogen, 69 to 73% methane and 2 to 4% carbon dioxide. Pilot-scale ABR experiments were conducted by using two or three upflow reactors in series. The results showed that between the OLR of 0.10 - 0.86 g COD/(L.d), the significant decrease of COD concentration within the first reactor was observed. The COD removal rates were found to increase from 0.09 to 0.66 g COD/(L.d) with increasing OLR from 0.10 to 0.86 g COD/(L.d); resulting in an average treatment efficiency of 77 -.86%. The results obtained from batch tests were used in computer simulation to determine the constant and reaction orders. The constant C of Compartments 1, 2, 3 and 4 were found to be 3.8x10- 7 , 1.9x10- 5 , 0.586 and 0.522, respectively and the reaction orders of Compartments 1, 2, 3 and 4 were 3.9, 3.1, 1 and 1, respectively. The finite difference method of the model coupling mass transfer into a biofloc with the reaction was applied to simulate the ABR performance. The model simulation of the laboratory-scale ABR process showed that the observed and predicted effluent dissolved COD concentrations agreed well between the OLR of 1.82 - 2.14 g COD/(L.d). (ii) The overall results obtained from this study have shown that ABR process is efficient for the treatment of slaughterhouse wastewater and compares favorably with other anaerobic systems. |
