Considerable oil can be removed by a separation tank because oil floats on top and there are separate drains for oil and water (see link). Oil is also separated using special porous filters that allow water but not oil to pass through. Centrifugal oil separators work like the separation tanks except that the rotational force speeds up the 'settling' process and operates with a continuous flow. Oil is also separated using special porous filters the allow only water to pass through.

Store used oil in a settling tank. Oil normally floats over water
Settled down water is drained from the tank. Heat the remaining oil to 230 deg. F and water evaporates. The remaining oil may be filtered and sampled.

I think in water treatment plants, they wait for the oil to rise to the surface of the water and skim it off with some kind of machine.

in water treatment plants the oil is separated in oil separators where oil floats on water due the density differance. the oil is skimmed off from top layer.

we used an oil skimmer on our settling tanks to separate any oils from the incoming liquid.
