Brief description of how a WET substances DOT vacuum truck works:
- Vacuum transport
The movement of the product is a result of the pressure difference
- Volume increase
As the material makes the transition from the suction pipe connection (6”) to the tank (which is bigger than 6”), the liquid separates from the air flow.
Vapours/liquids are removed from the air flow in the service water tank.
The remaining air flow is discharged through a vent pipe
