Separation and extraction
of the oil

Where do water and pomace end up?
Vegetation water
The Sansa
The vegetation water is stored inside our settling and storage tanks, then it is sucked up by a tanker truck and sent to a Biogas plant.
It is transported via a screw conveyor into a pit separator, whose purpose is to separate the pit of the crushed olive from the pomace. The depitted pomace is discharged into a trailer for delivery to a Biogas plant, while the pits are placed into bags and stored on pallets ready for sale.
