Abstract: A system and method for automated single tank surface treatment, the system including a process tank, a manifold fluidly coupled to the process tank, a controller coupled to the manifold, and a plurality of holding tanks in fluid communication with the process tank via the manifold. The process tank may include a conductive support configured to hold a workpiece to be anodized and electrically coupled to a power supply source, and one or more cathodes electrically coupled to the power supply source, wherein the power supply source is configured to apply a voltage between the one or more cathodes and the workpiece via the conductive support. The system may also include a pH sensor, a temperature sensor, a cooling coil, a heating element, a level sensor, a vacuum outlet, a pressurized air inlet, and a pressure sensor.
