With the apparatus being used, the plating solution can be recovered in the manner that sludge and iron are removed from the plating solution used for electroplating of a steel strip. Further, with the apparatus being used, even when stopping the operation of a device(s) related to iron removal, a continuous electroplating operation can be maintained without reducing the operation rate of the sludge removing device.

摘要： The process consists in passing the liquid to be purified and a superabsorbent, preferably of polyacrylic type, through a column, the upward speed of the liquid being chosen such that, in the column, the superabsorbent which is merely swollen is in a stationary dynamics regime, whereas the superabsorbent laden with polyvalent ions settles at the bottom of the column. Application to the treatment of the aqueous rinses of articles which have undergone a nickel-plating treatment.

摘要： An electrolytic treatment method and a unit in which such a method is practiced are provided wherein heavy metal hydrous oxides are precipitated and recovered from a dilute waste stream to render the waste stream suitable for discharge. The waste stream is passed into the cathode chamber of an anion exchange membrane delineated electrolytic cell and subjected to high current density electrolysis to promote the formation of regular, noncompressible metal hydrous oxide crystals. Fluoride ion is added to the precipitate-containing waste stream, the precipitate is filtered and the clarified liquid waste stream is split so that a portion is discharged and a portion is recycled into the metal ion-containing waste stream for further treatment.

摘要： Described is a method of separating and recovering metal values from a waste stream containing metal hydroxides comprising the steps of providing an aqueous waste stream containing metal values including chromium; subjecting the waste stream to an oxidation process to convert the chromium to chromium (VI); precipitating the other metal values in the aqueous stream by adjusting the pH of the stream to cause the precipitations; and separately recovering the chromium (VI) from the remaining metal values. The process described pertains to separating and recovering metal values such as those from an electroplating process or an electroless process wherein the metals may be iron, cobalt, zinc, cadmium, nickel, copper, silver, aluminum and chromium. The chromium recovery step is performed by oxidizing chromium (III) to chromium (VI) preferably in the presence of a manganese catalyst and preferably utilizing ultrasound waves. The remaining metal values are separated by the use of a chelating ion exchange resin.

摘要： Multivalent heavy metal ions are removed from metal plating waste streams by passing them through an unexpanded vermiculite cation exchange column. The column is effective to remove copper, zinc, and nickel ions and mixtures thereof. Where cyanide and cyanide-metal complexes are also present in the plating waste stream, the stream is pretreated to destroy the cyanide and cyanide complexes prior to passage through the ion exchange column.

摘要： An exfoliated vermiculite cation-exchange column is used to remove multivalent heavy metals (copper, zinc, nickel, chromium, etc.) from metal plating wastes. The exfoliated vermiculite may be either chemically or relatively low-temperature thermally expanded vermiculite ore. It preferably has a cation exchange capacity of over 80 meq/100g. Exfoliated vermiculite particle sizes of less than approximately 10 mesh are preferred as the column packing. The ion-depleted vermiculite from the exchange column after use can be further expanded thermally and used as a lightweight filling material.

摘要： In a unit for reclaiming plating wastes containing chromic acid and the like, the rinse liquid from the first of a plurality of wash tubs into which plated articles are dipped successively to rinse off the plating solution, is sucked into a tower where it is heated by steam partially to vaporize and concentrate it to plating strength. The vapor generated in the tower is passed through a check valve to an ejector, where it is introduced transversely into a jet of cooling water to be condensed and conveyed with the stream of cooling water to a reservoir. The cooling-water jet develops a vacuum in the tower; and a trap is interposed between the tower and ejector to trap any cooling water which a faulty check valve might otherwise allow to back up into the tower.
