摘要： A liquid filter having a casing with liquid inlet and outlet and characterized by a filter element comprised of a multitude of absorbent cellulosic cloth discs, such as terry cloth, in compressed stacked face-to-face relation around a tube disposed between the inlet and outlet. The tube is open at one end and closed at the other and perforated along its length. The liquid to be filtered is forced to pass radially between adjacent cloth discs between the perimeters of the discs and the tube. Dissolved iron is removed from water passed through the filter if the cloth discs are saturated with potassium permanganate.

摘要： ACIDIFIED AMMONIUM PERSULFATE SPENT AS ETCHANT FOR VICALLOY (AN ALLOY CONTAINING COBALT, VANADIUM, AND IRON AND WHICH MAY ALSO CONTAIN SILICON AND MANGANESE) IS TREATED WITH AN IRON REAGENT FOR REDUCING PENTAVALENT VANADIUM AND TRIVALENT COBALT. THE SOLUTION IS THEN NEUTRALIZED TO THROW DOWN SUBSTANTIALLY ALL OF THE VANADIUM FROM THE SOLUTION AS INSOLUBLE SALTS OF TRIVALENT AND TETRAVALENT VANADIUM, AND TO REMOVE THE IRON AS IRON HYDROXIDE. THESES INSOLUBLE MATERIALS, TOGETHER WITH ANY SILICON DIOXIDE, ARE THEN SEPARATED FROM THE LIQUID. THE PH OF THE RESULTING LIQUID IS HIGHLY ALKALINIZED TO THROW OUT THEREFROM SUBSTANTIALLY ALL OF THE COBALT AND THE REMAINING IRON AS INSOLUBLE MATERIALS OF BIVALENT COVALT AND IRON HYDROXIDE. THSES LAST INSOLUBLE MATERIALS ARE THEN SEPARATED FROM THE LIQUID, WHICH IS THEREAFTER NEUTRALIZED.

摘要： A process for the treatment of aqueous sulphuric acid solutions of a metal salt or salts containing ferrous sulphates wherein the pH value of the solution is adjusted by the addition of a calcium compound to selectively precipitate calcium sulphate after which the precipitated calcium sulphate is separated and calcined before adjusting the pH of the mother liquor to a value in the range 7 to 9 by the addition of a calcium-containing compound to precipitate there from solid metal compounds which are then separated and/or calcined.

摘要： Cations of metals other than the alkali metals may be precipitated practically completely from their aqueous solutions at a pH of 4 or higher by N-acylamino acids whose acyl group is alkanoyl or alkenoyl having seven to 25 carbon atoms, the acylamino group being connected with the carboxyl group by divalent alkylene having one to five carbon atoms. The voluminous precipitates include even more of the metal ions originally present and settle faster in the presence of small amounts of polyhydric alcohols, polyethers, alkali metal silicates, or alkali metal borates. Water polluted with heavy metals can be made potable by this method.

摘要： Method and apparatus for removing heavy metals as sulfides from aqueous liquids. The aqueous liquid is introduced into a circulating liquid loop wherein there are established a mixing zone, a controlled precipitation initiating zone, a crystal growing zone and a crystal settling zone. The aqueous feed liquid containing H.sub.2 S dissolved therein and at a pH below that at which the sulfide is precipitated is mixed in the loop with a pH-adjusting liquid; and the degree of supersaturation with respect to the metal sulfide is maintained within the controlled precipitation initiating and crystal growing zones in the metastable condition so that the growth rate of the metal sulfide crystals remains greater than under uncontrolled conditions vis-a-vis the nucleation rate to effect the production of metal sulfide crystals of a character which makes it possible to separate them through clarification and filtration.
