Abstract
Abstract A decantation apparatus comprises a horizontally elongated vessel having a top section and a bottom section and being arranged to be filled to a predetermined level of the top section. Feed means feeds the suspension into the vessel. A distributor chamber extends lengthwise of the vessel substantially coextensive within the top section and receives the suspension from the feed means. An elongated loading well extends lengthwise of the distributor chamber below the same and substantially coextensive therewith. It communicates with the distributor chamber and projects downwardly into the bottom section. A pair of outlet channels extends lengthwise of the loading well at opposite lateral sides thereof at the level of the suspension. Discharge means is provided in the bottom section extending lengthwise of the vessel at least substantially coextensive therewith for discharging the solid component of the suspension which has settled in the bottom section.
