STORMWATER FILTRATION SYSTEMS AND RELATED METHODS

摘要

A stormwater filtration system includes one of a filter cartridge structure or a filter basket structure. The structure includes an internal collection space surrounded by a filter media bed, an outlet opening toward the bottom of the internal collection space for delivering water out of the structure, and a valve assembly associated with the outlet opening. The valve assembly is configured to provide a variable flow out of the outlet opening according to level of water within the internal collection space.
