Prevent and remove organics from reservoir wells

A method for operating an electroplating vessel, the vessel having walls configured to hold a liquid solution of a metal plating material and including an organic species, the liquid solution contained within the vessel at a first level below a top rim of the vessel, wherein when a workpiece is immersed in the liquid solution to displace a volume of the liquid solution resulting in the liquid solution level rising within the vessel to a second level above the first level, and wherein a barrier material lining is located on the walls of the vessel and at, or above, the second level, the method comprising:

• after immersing the workpiece, immersing a removable object in the liquid solution contained in the vessel;
• the removable object when immersed causing displacement of a volume of the liquid solution resulting in the liquid solution level rising within the vessel to the second level;
• and
• removing the removable object from the liquid solution, wherein when the removable object is removed, the liquid level is lowered to the first level while simultaneously washing the organics back into the solution.
