摘要：The research for determining the optimum process conditions of the co-composting of bagasse and filter cake had been done in a laboratory scale.However,to be applied in the industry,it is necessary to compare the performance of co-composting process of laboratory scale with those of a larger scale.The objective of this study was to compare the performance of co-composting process of bagasse and filter cake on scale of 100 kg of composting material to laboratory scale.The main performance parameters evaluated included the kinetics of the composting process and the effect of aeration rate on the declining rate of C/N.The factors maintained were in the forms of reactor geometric similarities,aeration rate,and the initial C/N.The research was carried out in aerated pile for 60 days with initial C/N of 50 and added aeration rate of 0.4 L/minute.kg for one hour per day during the first week.Observation on the scale of 100 kg showed the same process condition as the one conducted in laboratory scale reaching the temperature at mesophilic phase at 41 oC and 36 oC,pH neutral,optimum range of moisture content,and nitrate increased after the second week.Based on the results,the process of co-composting at 100 kg scale gave a lower composting rate than process at 5 kg.Moreover,aeration treatment in the first week for 100 kg scale had no effect on the rate of C/N decline.Compost quality on 100 kg scale was completed with the standard and had higher water holding capacity than compost from laboratory scale.
