ABSTRACT:
A cylindrical vessel having a horizontal, longitudinal axis of rotation is filled with biofilter material and receives gases through a perforated dispersion pipe located along the axis. Humidified gases pass through the biologically active filter material where the gases are converted into elemental gases, carbon dioxide, biomass, or water. The vessel is lined with geotextile material which acts as a collection plenum for the gases which flow radially outward to the lining. Collection pipes located at regular intervals between the lining and the vessel conduct the gases to a manifold, also located on the axis. The vessel is rotated periodically, e.g. weekly, for several rotations in order to mix the filter material, break up any compacted material, and collapse any fissures.
