Gravitational separator and drainwater treatment system for use in a horizontal passageway

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