摘要： A storm drain filter (10) functioning to remove selected substances from water flowing through a municipal storm drain. The storm drain filter (10) has an absorption filter (18) functioning to absorb selectable substances from a liquid. The absorption filter (18) comprises an absorption filter frame (18A) enclosing an absorption filter absorbing material (18B) between pairs of at least two absorption filter longitudinal retainers (18C) and at least two absorption filter transverse retainers (18D). The at least two absorption filter longitudinal retainers (18C) and at least two absorption filter transverse retainers (18D) function to retain the absorption filter absorbing material (18B) within the absorption filter frame (18A). A tray (16) functions to support the absorption filter (18). The tray rear (16B) comprises at least one orifice (16BA) functioning to permit liquid to flow therethrough. The tray front (16D) and tray rear (16B) further comprises at least two tray front fastener hole (16DB) which functions to receive a tray holddown mean functioning to hold the filter in place. A rack (14) which functions to securely restrain at least two trays (16) in an alternating pattern. The rack (14) is inserted into the cage (12) having alternating placement of the at least two trays (16) allows large debris to pass through the storm drain filter (10). A cage (12) functions to receive the rack (14) therein. A sealing means is securely attached to an upper perimeter of the cage (12) functioning to seal the interface between the cage (12) and a drain device opening.
