Case Study

Tilbury STW

Storage Silo with Sliding Frame Discharge

Saxlund were chosen by Anglian Water to design, manufacture, and install a dewatered sludge cake truck loading silo for the Tilbury Sewage Treatment Works.

The silo shell was manufactured as bolted stainless steel panels, which reduces the carbon footprint by being 100% recyclable.

The truck loading silo is loaded by cake pumped into the side of the silo, maximising the storage volume. The silo is discharged by the Sliding Frame which is fitted onto the baseplate of the flat bottomed silo supported high above the ground.

The Saxlund Sliding Frame reciprocates across the silo floor promoting mass flow and discharges the sludge cake into a screw conveyor. The screw conveyor conveys the material towards the outlet and discharges through a hydraulically operated slide gate valve and into the truck waiting below.

Saxlund supplied and installed the MCC/PLC to control the unloading of the silo into the trucks, and the site cabling for the project.
