Floating Oil Absorber

Briefly Discuss the Working Principle of Oil Absorbers:
The oil skimmer, a float-type stainless steel pot, draws the floating oil on the surface of the oil pool into the separator tank of the collection machine. The water and oil are then separated a second time within the tank, while impurities are retained by a larger filter tube. Once the tank is full, the water is detected by the level sensor and drained back into the pool through the drain. The oil remains in the tank until a large volume of oil flows out of the drain, indicating the tank is full. The oil can be emptied through the oil outlet and transferred into a spare empty drum.
