Abstract

Apparatus for separating floating solids from a volume of liquid contained within a container (1) an edge of which forms a weir (3) comprises means (7,8) for sweeping surface floating solids over the weir (3). Operation of the sweeping means (8) is confined to an area of the liquid surface adjacent to the weir (3). Surface floating solids are continuously drawn into the 'operating' area by tension in the liquid surface.
