A treater for electrostatically separating entrained saltwater from oil during longitudinal flow through a horizontally elongate metal tank, wherein the gas vapor and freewater are separated by gravity separation. Foam is eliminated by passing the gas vapor through an oil wash and coalescing of the entrained saltwater droplets is accomplished by flowing the emulsified oil downward through an electric field. The force of the downward flow through the electric field sweeps the coalesced saltwater drops from the electric field. The oil containing the coalesced water drops flows horizontally from the electric field rearward in the treater for gravity separation of the coalesced saltwater drops from the oil. Saltwater free oil, gas vapor and saltwater are discharged separately from the treater.
