A water filter system with a filter housing, a filter media, a filter coupling, and a dynamic seal. The filter housing has a top plate and a bottom plate which are both water-permeable, as well as a cavity between the top plate and the bottom plate. The filter media is within the cavity of the filter housing and extends through the bottom plate of the filter housing. The filter coupling extends upward from the top plate and is configured to attach to a float with at least one air chamber. The dynamic seal is coupled to the filter housing along a perimeter of the filter housing and is configured to extend beyond a perimeter of the float, maintain contact with a wall of a water container, and restrict water from passing between the dynamic seal and the wall of the water container.

A floating liquid intake for a liquid suction removal system, the liquid intake comprising housing defining an internal cavity. The housing has a hollow and buoyant annular body, an upper cover and a lower cover. The internal cavity is formed between the upper and lower covers. A substantially annular inlet is formed in the annular body for ingress of liquid into the cavity. The annular body has a buoyancy sufficient for the liquid intake to float in a liquid with the annular inlet submerged below the surface of the liquid in which the liquid intake is floating. A pipe extends into the cavity and the pipe includes an inlet that in use is open below the surface of the liquid within the cavity. The pipe extends outside of the cavity for connection to a liquid suction removal system.

The present invention relates to a device (1) for filtering storm water inside a storm drain. The device (1) comprises a filter unit (2), a metal capturing ballast unit (6), and a floating carrier (4) for carrying the filter unit and the metal capturing ballast unit (6). Whereby, in use, the device (1) is arranged in a floating condition in the storm water of the storm drain. The filter unit (2) is at least partially arranged above a surface (5) of the storm water, and the metal capturing ballast unit (6) is arranged below the surface (5) of the storm water. The metal capturing ballast unit (6) comprises a solid material for capturing metal and providing ballast.
