Abstract
The objective of this study is to establish the model of deodorization mechanism using GLASS FOAMING MATERIAL. Ammonia gas was targeted as to remove component of odorants in this study. Ammonia gas is one of the main component of odor from composting facilities. We assumed that the deodorization mechanism consists of the dissolution into water which is holding in glass foaming material and the decomposition of ammonia by microorganisms. The modeling of deodorization mechanism was attempted by using theoretical equations such as the doble boundary membrane theory, Fick's law, and Monod's equation. The model were established using COMSOL Multiphysics, a physical simulator. The validity of the model was verified by performing calculations up to 30 hours after the start of the experiment under the same conditions as in the microbiological degradation experiment. The results of the calculations showed that the model represented well the experimental values of the concentration of each substance in the holding water. In addition, calculations were performed for up to 7 days with input of the operating conditions of the deodorization equipment used in the actual composting facility to confirm the reproducibility of the model.
