Gravity Vacuum SystemClick to enlarge
Refuse will be thrown into the chute via Volumetric Control Hopper Door.
When the refuse reaches the pre-set level, STREAM Control Centre (SCC) will trigger the Centrifugal Fan (CF) to create the vacuum and airflow inside the piping system.
The Discharge Valve (DV) will be opened to discharge the refuse to piping network. Primary Air Intake (PAI) will be opened to allow the air.
The refuse will be transported via the piping network to Bin Center in the speed of 20 – 25 m/s.
In the Bin Center, the refuse and air will be separated in the Waste Container or Waste Separator.
The air will be filtered, DEODORIZED and discharged.
