The present disclosure provides a degreasing apparatus which may be made at least partially, or substantially, of at least one plastic material, for use with solvents having relatively low boiling points that are chemically compatible with plastic materials, such as 1233zd (1-chloro-3,3,3-trifluoro-propene, CF.sub.3CH═CHCl). Plastic degreasing apparatuses may comprise a tank comprising a side wall and a bottom wall, a partition coupled to a lower portion of the tank, dividing the tank into an immersion sump and a vaporizing sump, a heating element located within the vaporizing sump, and a condensing element positioned above the lower portion, wherein at least one of the side wall, the bottom wall, and the partition is made of a plastic material.

Aspects treat and remove a layer of scale comprising iron oxide and alloying elements oxides that is formed on an advanced high strength metal surface comprising at least two (2) percent by weight of alloy. A first conditioning process compromises structural integrity of or removes iron oxide within the scale layer to expose the alloy oxide to chemical engagement with a disposed aqueous alkali salt solution that is heated to transforming one or more alkali salts within the disposed solution into a quasi-molten form. The alloy oxide is oxidized via reaction with the solution quasi molten alkali salt(s) and water, forming one or more water soluble alkali alloy compounds. A water rinse dissolves and rinses the water soluble compound(s) from the steel product surface of the advanced high strength, leaving a film of iron oxide on the surface that is removed via a final pickling process.

To realize excellent durability of an apparatus, realize a dissolved gas amount suitable for propagation of ultrasonic waves, and stably generate fine bubbles that further comply with a treatment using ultrasonic waves. An ultrasonic treatment apparatus according to the present invention includes: a treatment part capable of accommodating a treatment liquid and an object to be treated; an ultrasonic generator that is provided in the treatment part and applies ultrasonic waves to the object to be treated; and a circulation path for circulating the treatment liquid in the treatment part, in which a fine bubble generator which performs deaeration on an extracted treatment liquid and generates fine bubbles in the treatment liquid, is provided to the circulation path, in series with a treatment liquid extraction pipe. The fine bubble generator has two or more narrow portions each having an opening flow path with a size narrower than an inside diameter of the treatment liquid extraction pipe, in which the opening flow paths of the narrow portions adjacent to each other are configured to prevent the treatment liquid from proceeding straight, and an opening cross-sectional area at each pressure reduction zone satisfies a predetermined relation.

The amount of wash water to be consumed in an electrodeposition coating facility and the amount of used wash water to be discharged that requires post-treatment are reduced. To achieve this object, an electrodeposition coating facility that includes a degreasing process section A, a post-degreasing rinse section B, a chemical conversion process section C, a post-chemical-conversion rinse section D, an electrodeposition coating section E, and a post-electrodeposition rinse section F is provided with a filtration process apparatus 4 and a wash water recycling line 5. The filtration process apparatus 4 performs a filtration process on wash water W after being used to wash an object to be coated 1 in the post-electrodeposition rinse section F. The wash water recycling line 5 feeds, to the post-chemical-conversion rinse section D, the wash water W after being subjected to the filtration process in the filtration process apparatus 4 as wash water W to be used to wash an object to be coated in the post-chemical-conversion rinse section D.

An acidic treatment liquid processing apparatus includes: a tank having an interior space; a diaphragm permeable to a metal cation and separating the interior space of the tank into a first chamber and a second chamber; a first electrode disposed in the first chamber; a second electrode disposed in the second chamber; a power supply configured to apply a voltage while using the first electrode as an anode and the second electrode as a cathode; a first liquid passing part configured to pass an acidic treatment liquid containing a dichromate ion and a metal cation into the first chamber; and a second liquid passing part configured to pass an acid aqueous solution into the second chamber.

In an acidic treatment liquid processing apparatus, a space between a first electrode and a second electrode spaced from each other is separated by a first diaphragm permeable and a second diaphragm into a first chamber, a second chamber, and a third chamber. While the first chamber is fed with an acidic treatment liquid containing a dichromate ion and a metal cation, the second chamber is fed with a first acid aqueous solution, and the third chamber is fed with a second acid aqueous solution, a voltage is applied using the first electrode as an anode and the second electrode as a cathode.
