Round silos – The sliding frame is built as an elliptical frame, made of solid steel bars profiled to a wedge shape. This elliptical framework with its wedge profile, pushes under the sludge in one direction and draws it toward the discharge opening in the other, thereby allowing near total emptying of a flat bottom silo.

The role of sludge thickening is to thicken the sludge of low concentration generated in STPs, and to make subsequent processes such as sludge digestion and sludge de-watering more effective. Thickened sludge may be of two kinds: primary sludge generated in the primary settling tank and excess sludge generated in the secondary settling tank.

The existing belt conveyor has been reversed so it delivers the sludge cake to the PCP inlet hopper rather than to the old truck loadout bays. Dewatered sludge cake is distributed to three 160-cubic-yard storage silos. Each silo is mounted on load cells that weigh the contents of the silo and transmit a weight signal to the main control panel.
