| Abstract | ||||
| This study describes the macromixing within a hydrodynamic vortex separator and considers its potential as a disinfectant contact tank. It is typically used in the sedimentation process during the treatment of sewage. The macromixing was investigated by conducting tracer experiments from which are retention time distribution was obtained and interpreted to characterize the mixing. The separator was operated in a continuous mode with no base flow, and the retention-time distribution was obtained using a pulse input for a range of the flow-rates. The method of moments was used to obtain various functions such as axial dispersion and tanks-in-series model parameters. The study revealed that the HDVS is best treated as an imperfect plug-flow mixing device with a large amount of dispersion. | ||||
