A mobile unit for the treatment of BS to recover the saleable oil therefrom, and to clean the oil storage tank. The cleaning and treatment system is mounted on a truck or the like, so it can be taken to individual storage tanks from which the BS and water is to be removed from the bottom thereof and the storage tank cleaned. The components of the system are a BS treatment tank, a heating unit with a burner and coils, with the necessary pipes, valves and pumps to withdraw the BS from the bottom of the oil storage tank, heat and treat the BS until the water and marketable oil are separated and the saleable oil returned to the storage tank. The water and residue are discharged to a suitable place of disposal.
