摘要： A method for producing a surface-activated crystalline titanium oxide product having a high adsorptive capacity and a high rate of adsorption with respect to dissolved contaminants includes the steps of preparing a titanium oxide precipitate from a mixture comprising a hydrolysable titanium compound and heating the precipitate at a temperature of less than 300° C., without calcining the precipitate. Preferably, the titanium oxide product includes crystalline anatase having primary crystallite diameters in the range of 1-30 nm. The surface-activated crystalline titanium oxide product is used in methods to remove dissolved inorganic contaminants from dilute aqueous streams by suspending the product in an aqueous stream or by filtering an aqueous stream through a bed of the product. In another method, a hydrolysable titanium compound is added to an aqueous stream so that titanium oxides form as a co-precipitate with dissolved contaminants within a bed of particulate material.

摘要： Dissolved inorganic contaminants are removed from a dilute aqueous stream by adding a hydrolysable metal compound to the aqueous stream, co-precipitating a hydrolyzed metal compound with the inorganic contaminants, and, concurrently with the co-precipitation step, filtering the co-precipitate from the dilute aqueous stream using a packed bed filter. The process may be carried out so that the metal oxide co-precipitate forms within the packed bed. Dissolved contaminants, particularly arsenic compounds, are removed more efficiently than by conventional co-precipitation/filtration processes. An apparatus for carrying out the process provides for injection of the hydrolysable metal compound into the dilute aqueous stream immediately upstream of the packed bed filter, without an intervening flocculation or sedimentation vessel, thereby providing an effective contaminant removal system that requires a smaller footprint and lower capital cost than conventional water treatment systems.

摘要： A process for stabilizing chromium in a chromite ore processing residue (COPR) comprises the steps of adding an acid to consume the excess alkalinity of the COPR, resulting in a pH of less than 10; and adding a chemical reductant to the COPR to convert any hexavalent chromium present to trivalent chromium. A source of sulfate may be added to the COPR to reduce heave potential and improve its geotechnical stability. Treated COPR may be encapsulated in a material suitable to prevent contact between the COPR and water, such as an asphalt.
