Clearance of waters after pumpingout of supernatant water
This variant makes sense with waters, which have a clear water phase above sludge layer and make a lowering of water level possible. In this case we can pump out water on short notice and can pile the pending sludge layer fornatural dewatering in heaps.
Special machines like swamp track dozers and long-armed dredgers make the movement of sludge volume possible for support of solar drying.
