    Abstract: An adsorbate is removed from an adsorbent by contacting the adsorbent with a supercritical fluid which is a solvent for the adsorbate. The supercritical fluid containing the dissolved adsorbate is then subjected to a physical treatment which renders the supercritical fluid a nonsolvent for the adsorbate and makes it possible to remove the adsorbate from the supercritical fluid. The supercritical fluid is then subjected to another physical treatment to restore it to a state wherein it is a solvent for the adsorbate so that it may be reused. The process and apparatus are particularly suitable for adsorbent regeneration in the treating of waste water.

    Abstract: A method of treating water containing chromate by bringing the water-to-be-treated into contact with ion-exchange resins, which comprises: passing the water-to-be-treated through a bed of weakly acidic cation exchange resin in H-form at first; subsequently passing the same water through a bed of weakly basic anion exchange resin in salt form thereby to remove said chromate from the water; introducing an alkali metal hydroxide solution into said weakly basic anion exchange resin bed in the reverse direction relative to the direction of passing of the water thereby to elute chromate; and further introducing an acid solution therein thereby to convert the weakly basic anion exchange resin into salt form.

    Abstract: Heavy metal ions are recovered from a dilute aqueous solution by flowing the solution through either a single bed of ion-absorbing material in successive forward and reverse directions, or through a first bed of ion-absorbing material and thereafter through a second bed of ion-absorbing material in the reverse directon of flow. The reversal of flow is to periodically mechanically agitate a bed of ion-absorbing material to dislodge contaminants, such as gelatin.The method is accomplished by using one enclosed vessel, or a pair of enclosed vessels, that have valves to control the direction of flow. A timing device preferably automatically reverses the direction of flow about each hour.After a relatively large number of reversals of flow the heavy metal ions are recovered from the ion-absorbing material and the same is regenerated in the process to again absorb ions from the dilute aqueous solution.

    Abstract: Bottler's liquid sugar is produced essentially from brown sugar, which is derived from cane sugar and crystallized in one or more intermediate strikes, by remelting the crystallized product of one or more intermediate strikes, filtering the remelted product, and passing the filtered product in contact with chloride form of Type-1 strong-base anion-exchange resin. An array of plural columns, which contain similar resin, is operated in a merry-go-round sequence allowing continuous operation. Countercurrent regeneration is preferred. Regeneration by an aqueous solution of hydrochloric acid followed by an aqueous solution of sodium chloride and sodium hydroxide allows service at 30.degree. C.
