Optimization of CO2 stripping systems for removing inorganic carbons from anaerobic digestate of food waste |
| 초록 |
The CO2 stripping could be used to remove inorganic carbon species and alkalinity in wastewater with a high carbonate contents. The aim of the present work was to optimize the performance of two CO2 stripping systems, so diffused and packed tower aerator. Experiments were conducted using anaerobic digestate of food waste in different agitation speed (0-500 rpm), temperature (25-65℃) and air flow rate (0-50 vvm). The results showed that the packed tower stripper was more efficient than diffused aerator. Most 80% of dissolved CO2 was successfully removed at the conditions of 65℃, recirculation ratio of 10, packing volume of 60% and gas/liquid ratio of 20 in the continuous packed tower stripper. This study was supported by grants from COWEB. (Project No. 2013001580002) |
