Abstract
The efficiency of a sewage settling tank is improved by providing the tank with a plurality of submerged, vertically spaced decks which divide the tank into a plurality of horizontal settling layers. This improves the settling rate in that solids travel a relatively short vertical distance before coming to rest on one or another of the decks. A floating siphon system having inlets at each deck level removes the settled sludge from each of the decks.
