Stormwater regulations are increasing calling for an increased level of treatment. This often takes the form of filtration systems. Two types of filtration systems used in stormwater are media filtration and membrane filtration.
Media Filtration systems are defined as filters that function through the use of physical capturing of pollutants, as well as absorption of pollutants through chemical reactions. Typical media based filtration systems are composed of sand, stone, organics, or other materials. The media utilized is typically chosen to target specific pollutants for removal.
