Method and Apparatus for Removing Metals from Roof Top Storm Water Runoff

摘要

A method and apparatus for the removal of metals and cleanup of roof top storm water runoff comprising a drum structure which includes at least two media beds for filtering the storm water runoff. The first media bed filters out particles of toxic metals and metal ions are absorbed on the media material in the first media bed. The storm water then runs through the second media bed which filters out additional particles of metal and metal ions are absorbed on the media material in the second media bed resulting in a clean effluent
