A system, comprising: a heating chamber that heats bunker fuel oil passing therethrough; a first mixer stage fluidly coupled to the heating chamber, wherein the first mixer stage is adapted to mix the bunker fuel oil heated by the heating chamber with water containing one or more treatment chemicals; a first water/fuel separator stage fluidly coupled to the first mixer stage, wherein the first water/fuel separator stage is adapted to separate the water from the bunker fuel oil after a first cleaning operation; a second mixer stage fluidly coupled to the first water/fuel separator stage, wherein the second mixer stage is adapted to receive the bunker fuel oil from the first water/fuel separator stage; a treatment chemical inlet fluidly coupled to a water supply that is fluidly coupled to the second mixer stage, wherein the treatment chemical inlet is adapted to provide the one or more treatment chemicals to the water supply, the one or more treatment chemicals are mixed with water in the water supply prior to entering the second mixer stage, and the second mixer stage is adapted to mix the water that has been mixed with the one or more chemicals prior to entering the second mixer stage with the bunker fuel oil from the first water/fuel separator stage to create an emulsion, the particular one or more treatment chemicals being selected to assist in the removal of pollutants from the bunker fuel oil contained in the second mixer stage; a microcavitation chamber fluidly coupled to an outlet of the second mixer stage, wherein the microcavitation chamber is adapted to create cavitation bubbles in the emulsion; a reactor chamber fluidly coupled to an outlet of the microcavitation chamber and receiving the emulsion, the reactor chamber having a plurality of electrolysis plates that cause a current to pass through the emulsion, wherein the microcavitation chamber is positioned directly above the reactor chamber, and the first and second mixer stages (22, 34) are positioned on one or more sides of the microcavitation chamber; a second stage water/fuel separator stage fluidly coupled to the reactor chamber, where-in the second stage water/fuel separator stage is adapted to output bunker fuel oil after it has been separated; and a connection fluidly coupled to a water outlet of the second stage water/fuel separator and a water inlet to the first stage mixer that provides water exiting from the second stage to be used in the first mixer stage, wherein the water containing the one or more treatment chemicals exits the water outlet of the second stage water/fuel separator stage, travels through the connection, and enters the water inlet to the first stage mixer. a heating chamber that heats bunker fuel oil passing therethrough; a first mixer stage fluidly coupled to the heating chamber, wherein the first mixer stage is adapted to mix the bunker fuel oil heated by the heating chamber with water containing one or more treatment chemicals;
