description abstractThe plenum-aerated biofilter (PA biofilter) is an unsaturated, single pass vertical flow biofilter with horizontal air plena within the media to enhance passive aeration. Plena enlarge the surface area of the air/media interface, increase oxygen ingress, and permit a reduction in the footprint of ammonium oxidizing biofilters. An experimental PA biofilter was operated on household wastewater pretreated in a primary settling tank. The prototype was a 7.3 cm (3 in.) inner diameter circular column, containing 61 cm (24 in.) of granular clinoptilolite media. Three 5.1 cm (2 in.) aeration plena were placed at successive 7.6 cm (3 in.) media thicknesses below the upper filter surface. The biofilter was operated for 28 weeks at hydraulic loading of
