ABSTRACT:
A filter compartment containing water with surface scum is bounded by first and second end walls and spaced side walls, the latter of which are spanned by a moving bridge. The bridge is movable between the ends of the compartment and has associated nozzles which direct a pressurized air or other fluid angularly against the upper surface of the scum layer to skim the scum towards at least one collecting pot, in which scum is collected, and from which the scum is withdrawn for delivery to a scum pit for further treatment or disposal.
