Sludge with 30–60% moisture and similar bulk materials often has poor flow, which makes storage and discharge harder than expected. As the material sits in the silo, it can accumulate and compact under its own weight, and that compaction increases the chance of arching or bridging at the outlet. When this happens, discharge becomes uneven and difficult to control.

To handle this, the storage step uses a sliding frame silo combined with multiple discharge screws. The goal is to keep material moving instead of relying only on gravity. At the bottom, hydraulic sliding frames move back and forth to disturb sludge near the outlet and help break bridges before they become a blockage. Meanwhile, the multi-screw discharge pulls material out across the full bottom area, supporting steady feeding and smoother unloading.

Integration into the dewatering line is also considered in the structure. The solid material storage silos have a rectangular body and a flat-bottom, modular design, which makes installation and system matching easier. Suitable for daily operation, storage silos for solid materials provide the strength and stability needed for long operating hours. Their smooth inner wall with an anti-corrosion coating helps protect the surface, while external reinforcing ribs support the body when the silo is full. If needed, a level gauge can be installed to track material quantity, and the usable storage volume is sized to handle viscous materials comfortably.
