Abstract
Method and apparatus for removing material from a gas stream. The gas stream with entrained material is moved downwardly through a filter bed of loose filtering solids of not more than 1.4 millimeter size, simultaneously with the passage of liquid downwardly through the filter bed which wets the surfaces of the filtering solids. Backwashing at intervals cleans the surfaces of the filtering solids of material that has accumulated thereon.
