If the vertical filter has additional aeration, the amount of energy it consumes will increase but the filter’s yield will increase by approximately 200%. Since this system takes up less space, it presents additional possibilities in urban environments. This type of filter is also used to treat cleaning water containing antifreeze from airport runways (such as Heathrow and Orly), for example. Aquarama, 2011
