Title: Method of refining of aluminum and its alloys
Inventor: PALENKO ANATOLIJ I
IPC: C22B21/06
Filed: 1994-12-14
Granted: 1997-09-10
Abstract: FIELD: refining of aluminum melts from impurities, for instance, of alkali metals, hydrogen and nonmetallic inclusions. SUBSTANCE: the offered method includes treatment of melt with flux, blowing with gas and filtering. Flux and gas are introduced in combination under the level of melt. Filtering is carried out under conditions of metal laminar flow. Flux and gas are introduced in ratio of (6-15):1 by specific flow rate, and metal flow rate at filter outlet is not in excess of 0.001 m/s. Application of combined supply of gas and flux excludes enveloping of bulb of gas-flux mixture with oxide film and continuous introduction of this mixture to under melt level contributes to more full and stable use of gas-flux mixture for refining from impurities, both, due to absence of oxide film on bubble surface and larger surface of contact of regent with melt, and also due to constant composition of supplied mixture and sufficient distance between bubbling zone and filter surface assists in suppression of turbulence in moving flow of melt and its feed to filter surface with flow velocities corresponding to laminar nature of motion. EFFECT: higher degree of refining of aluminum melts and reduced duration of refining process due more full use of gas and flux treatment of melt and provision of the most efficient conditions of filtration. 3 cl, 1 dwg, 1 tbl

Title: Method of removing chromates from waste water
Inventor: PUZEJ N V
IPC: C02F101/22
Filed: 1996-01-11
Granted: 1998-02-20
Abstract: FIELD: waste water treatment. SUBSTANCE: invention relates to cleaning waste water from Cr(VI) compounds and may be used in mechanical engineering, metal working, etc. for treating water prior to be reused or discarded into sewage system. Invention aims at removing Cr(VI) compounds from waste water without formation of concentrated unusable solutions. Objective of invention consists in regeneration of anionite and is achieved as follows: waste water is passed through filters with high-basicity anion-exchange resin that is further regenerated by reactive agent. Regeneration is accomplished by solutions of salts of strong acids or alkali metals or their mixture, and produced chromates are purified from chromates and reused for correcting composition and acidification. During these operations, concentration of alkali metal chlorides, sulfates, nitrates, or their mixtures is maintained within the range from 4 to 10 wt % and pH value as high as 3. When correcting water, solution obtained is fried of Cr(VI) compounds by reagents or by other ways and, once clarified and correction of salt concentration and pH value completed, are reused for regeneration operation. To prevent considerable dilution of eluate before regeneration and before washing after regeneration, filter is completely emptied by replacement with compressed air. Wash water polluted by salts and Cr(VI) compounds, is combined with other waste waters to be treated in the first treatment step. EFFECT: enhanced waste water treatment efficiency.
