The gaps between the lamellas get gradually smaller towards the place where the sludge cake is removed. The gap between the lamellas is first 0.5 mm in the thickening zone, 0.3 mm in the dewatering zone, and at the end the gap is 0.15 mm. The end compression plate increases pressure onto the sludge cake to achieve more efficient sludge dewatering.
