Abstract: An object of the present invention is to provide an improved vertical flow biofilter comprising a vertical filter bed system comprising a liquid permeable distribution layer, a liquid permeable treatment bed and a liquid permeable transition layer, wherein the permeability of the distribution and drainage layers being higher than the permeability of the treatment media bed. The biofilter system also comprises at least one bypass conduit extending vertically through the distribution layer and the treatment bed to terminate at the transition layer. A first open end of the at least one bypass conduit being substantially flush with the top surface of the distribution layer and a second open end extends to the bottom surface of the treatment bed. The bypass conduit being made of a liquid impermeable material and containing a permeable media having permeability higher than the permeability of the treatment media
