An apparatus for removing contaminants from emissions is provided with a reverse venturi shaped fluidized bed device integrated into the system. The system includes numerous component devices such as, but not limited to, an influent source, a fluidized bed device, a post filter device, and an effluent discharge. The system may also include one or more application specific pre-filter and/or post filter devices. The fluidized bed is constructed with a specific length to diameter ratio for optimum restrictive flow through a specialized filter media. The filter media is a mass of reactive material disposed within the fluidized bed which is in intimate contact with the emissions, as the emissions pass through the fluidized bed. The mass of reactive material contains an amalgam forming metal which chemically binds with the emissions that are passing through the system. Methods for removing contaminants from gaseous and non-gaseous emissions are also provided.

An air intake system for a vehicle has a conduit having an internal wall forming an air passage. A deflector is disposed within the air passage. A restricting structure is disposed within the air passage between the deflector and a conduit outlet. The restricting structure defines at least in part an opening substantially laterally aligned with the deflector. The restricting structure has a lateral wall disposed downstream of the deflector and extending within the air passage. The lateral wall has a front surface generally facing a conduit inlet, and a plurality of surface-increasing features provided on the front surface. Each of the surface-increasing features has a length of at least 1 mm measured from the front surface in a direction normal thereto. An air intake system having a collector connected to the deflector and positioned to collect at least some moisture from air flowing past the deflector is also described.
