Used motor oil which has impurities and dirt is fed right into a centrifuge. The centrifuge has a rotor that spins a really high RPM (revolutions each and every minute) also it pushes the impurities to the wall in the container that houses the rotor. This works because the mass from the impurities is greater than the mass from the oil particles. Appropriate extraction methods are used in order that impurities along with the clean motor oil are properly separated, and the oil is getting ready to be re-used. These filtering systems may also be appropriate for use with small-scale biofuel setups to take out any impurities.
