Abstract: Disclosed is a dewatering system and method for separating oil/water sludge into clean water and dewatered waste oil components in a repetitive batch process. The system comprises a vacuum distillation device. The vacuum distillation device has a feed port for loading the oil/water mixture, a processing chamber with heating and heating controlling means, a vapor phase port communicating with the chamber, a vacuum pump connected to the vapor phase port and configured to removing water vapor from the chamber to reduce vapor phase pressure to below atmospheric pressure, and a waste port configured for retrieving dewatered waste oil from a bottom portion of the chamber. The system further comprises a control unit configured to perform one or more control functions for controlling operation of the system in a programmed manner. A gravitational settling device is provided for pre-treating sludge to remove continuous phase water prior to loading the distillation device.
