A continuous galvanizing apparatus for multiple rods. The apparatus includes a kettle for heating and retaining a liquid therein with at least a portion of the kettle having an open top. A trough assembly retains liquid therein. The trough assembly is arranged above the kettle open top above the liquid level, with the trough assembly having at least one lower chamber within the kettle below a level of the liquid in the kettle. A pump in the lower chamber draws liquid from the kettle to the trough assembly. A plurality of entry openings are provided in the trough assembly along with a plurality of exit openings opposed to and aligned with the entry openings. Adjacent tubes in the trough assembly are aligned with the plurality of entry and exit openings.

A method of applying a treatment to a surface of an open body having a volume within an interior of the open body comprises; providing an inner structure (110) shaped to complement the shape of the interior of the open body and to fill a major portion of the volume or a major portion of a width of the interior of the open body; positioning the inner structure (110) within the open body in order to form a treatment fluid inner volume comprising an inner space (150) confronting an inner surface within the interior of the open body; and introducing a treatment fluid into the treatment fluid inner volume to thereby modify the inner surface of the open body by applying the treatment using the treatment fluid. Optionally, the method includes providing a tank (120) shaped to complement and contain the open body; positioning the open body within the tank (120) in order to form a treatment fluid outer volume comprising an outer space confronting the outer surface of the open body; and introducing the treatment fluid into the treatment fluid outer volume to thereby modify the outer surface of the open body by applying the treatment using the treatment fluid.

A substrate processing apparatus includes a processing tank, a holder, an organic solvent supply, a drainage port, a gas supply, and an exhaust port. The processing tank stores an aqueous layer. The holder holds a substrate. The organic solvent supply supplies an organic solvent onto the aqueous layer to form a liquid layer of the organic solvent. The drainage port discharges the aqueous layer from a bottom wall of the processing tank and causes the liquid layer of the organic solvent to descend from above the substrate to below the substrate. The gas supply supplies a gas of a water repellent agent to the liquid layer from above the processing tank while the liquid layer descends. The exhaust port is exposed on a side wall of the processing tank by the descending of the liquid layer and discharges the gas of the water repellent gas.
