[Also in Division B1] Raw water containing coagulation agents is fed from a supply 23 via conduits 24 and the apertured and rotatable shafts 8 of agitators (see Division B1) to a homogenization zone A to be mixed. Water and flocks pass through slots 4, 41 in partitions 2, 3 to sludge zones B in which a sludge blanket is formed and then through channels 5 into sedimentation zones C. Sludge settled in the sedimentation zones C passes to discharge through openings 19 and channels 18 in a series of beams 17. Partially clarified water from the tops of zones B flows into troughs 15 and passes with further such water removed from the tops of zones C via pipes 13 through channels 181 and openings 20 in the beams 17 to filter zones F from which clarified water is removed. The filters 21 are of the multi-layer type. Rinsing conduits 14 are provided for cleaning purposes.
