摘要：A hydrodynamic gravitational separator and an attending drainwater filtrationsection positionable within a horizontal flow passage of a drainage system utilizes acircular-walled collection cavity into which drainwater is directed so that a swirling motionis imparted to the drainwater collected within the collection cavity. Furthermore, a baffleplate is supported within the collection cavity adjacent the exit opening thereof to isolatethe exit opening from the swirling motion of the drainwater collected within the cavity.The filtration section includes a filter disposed downstream of the exit opening of thecollection cavity so that drainwater which exits the collection cavity is subsequentlyrouted through the filter.
