ABSTRACT:
A wastewater treatment device evaporates water from contaminant containing wastewater, to produce a contaminant concentrated residue. The device includes a transport, such as pump, for transporting wastewater to a wastewater applicator, and a wastewater applicator for applying the wastewater to an evaporating surface of an evaporator drum. A rotatable evaporator drum has a heat conductive evaporating surface, and a heater for heating the evaporating surface to foster the evaporation of water from the wastewater. A motor, chain and drive shaft are provided for rotating the evaporator drum, and a scraper is provided for removing the contaminant concentrated residue from the evaporating surface. A controller is provided for controlling the operation of the device.
