 Dichloromethane and benzene are toxic volatile organic compounds (VOC). Since they are readily dissolved in aqua media and harmful effect on ecology is expected, local governments strictly regulate the level of the exhausted VOC in to public sewerage. Especially, solubility of dichloromethane in water is much higher than that of typical VOC and the effective removal of dichloromethane from waste water is difficult. Although the acquisition of basic kinetic data is mandatory in order to design the practical removal plant of VOC by aeration, few experimental data were only observed in a beaker scale aeration test. The pilot scale plant for the removal of dichloromethane from waste water was designed on the basis of the beaker scale experimental kinetic data. In this report, the procedure of design of the practical plant for removal of VOC was established by calculation with the beaker scale kinetic data. The performance test of the constructed plant was also carried out. The modified intrinsic kinetic parameters are estimated after the performance test. And a guideline for the design is established.
