1. A method comprising:
directing crude oil into an interior chamber of a vessel of a dehydrator and desalter system;
performing a first liquid phase separation of water from the crude oil using a fixed super-hydrophobic mesh subsystem that includes at least one fixed super-hydrophobic mesh;
determining a residual water content in the crude oil using one or more inductor cup sets;
determining, based on the residual water content in the crude oil from the one or more inductor cup sets, whether to rotate a movable super-hydrophobic mesh for a second liquid phase separation of water process;
performing the second liquid phase separation of water process from the crude oil using the movable super-hydrophobic mesh;
performing a first electrostatic dehydration process on the crude oil using a first set of electrified metal grids;
performing a second electrostatic dehydration process on the crude oil using a second set of electrified metal grids; and
causing the crude oil to exit the vessel.
