- 6. 2010/04/00 6 • Air Compressors Togenerate the compressed air required to operate the discharge and air valves pneumatically • Exhauster – create the negative pressure and suction required to move the waste from the storage sections to the collection terminal. The air after reaching the waste separator goes through these exhausters to the dust and deo filter chambers. • Allied Air Flow Pipes – Venturi Pipes Completes the installation to create a total vacuum pipe net from the storage section till the air is cleansed and let out into the atmosphere.

The compactor is designed to compact the waste in the ration 1:3 or 1:5. Main Components in Station

It also controls the emptying operations of the various DV based on Time and Level. • SCADA The system can be monitored using the SCADA system which is the visual representation of the system at all times. The system is emptied based on Time and Level Cycles which ever is earlier. Main Components Main Components in Station
