Abstract: In order to remove fluorine from a zinc containing solution before zinc electro-refining in lower cost, fluorine is removed by adsorption from a zinc containing solution (leached solution) utilizing the character of the predetermined iron compound or zinc compound which can adsorb fluorine in an acid solution and desorb fluorine in an alkaline solution. The fluorine adsorbent/desorbent having adsorbed fluorine is treated in an alkaline solution, to desorb the fluorine. This makes it possible to regenerate the fluorine adsorbent/desorbent. Further, an electrolytic solution for zinc electro-refining can be prepared in lower cost, thus total zinc refining costs can be reduced.

Abstract: A process for the partial purification of contaminated phosphoric acid plant pond water is described, in which the pond water is treated sequentially, with two basic compounds, clarified, aged, clarified again and re-acidified. The thus treated pond water, still containing the majority of the phosphate originally present, can then be concentrated via the removal of essentially pure water, using any conventional means of concentration, without the formation of solid precipitates.

Abstract: Trace impurities such as organic compounds and carbon monoxide are reduced to sub-ppb levels in gases such as nitrogen, helium and argon, by gas purifying systems that contain an ultra-low emission (ULE) carbon material. Ultra-low emission (ULE) carbon materials is capable of removing impurities from a gas stream down to parts-per-billion (ppb) and sub-ppb levels without concurrently emitting other impurities such as moisture or carbon dioxide to the purified gas stream. The carbon material is superactivated by heating the carbon to temperatures between 300-800° C. in an ultra-dry, inert gas stream. The ultra-low emission (ULE) carbon material is handled and stored in an environment that minimizes contamination from moisture and other oxygenated species in order to maintain its ppb and sub-ppb impurity removal and low emission properties.

Abstract: Trace impurities such as organic compounds and carbon monoxide in reactive fluids such as ammonia, hydrogen chloride, hydrogen bromide, and chlorine are reduced to sub-ppb levels using gas purifying systems that contain a preconditioned ultra-low emission (P-ULE) carbon. P-ULE is capable of removing impurities from a reactive fluid down to parts-per-billion (ppb) and sub-ppb levels without concurrently emitting other impurities such as moisture or carbon dioxide into the purified reactive fluid. The P-ULE carbon is prepared by heating a carbon material to temperatures from 300° C. to about 800° C. in an ultra-dry, inert gas stream, to produce an ultra-low emission (ULE) carbon material, subjecting the ULE carbon to a second activation process under a reactive gas atmosphere to produce a P-ULE carbon and storing the P-ULE carbon in an environment that minimizes contamination of the P-ULE prior to its use in a gas purifier system.

Abstract: A waste water treatment equipment treats a fluorine waste water containing organic matter, nitrogen, phosphor and hydrogen peroxide by an anaerobic tank 3 in which a calcium carbonate mineral 9 is placed and an aerobic tank 15 in which the calcium carbonate mineral 9 is placed and into which a biologically treated water is introduced from a treatment equipment 444 of another system. Therefore, the fluorine in the waste water can be treated by the calcium carbonate mineral 9 placed in the anaerobic tank 3 and the aerobic tank 15 with the formation of calcium fluoride 11. The organic matter of the surface active agent and so on in the waste water can be treated by the microorganism included in the biologically treated water. Furthermore, nitrate nitrogen can be treated so as to be reduced to a nitrogen gas in the anaerobic tank 3, while ammoniacal nitrogen and nitrite nitrogen can be treated so as to be oxidized in the aerobic tank 15. That is, the waste water treatment equipment can highly efficiently treat the surface active agent, nitrogen, polychlorinated aluminum, macromolecular coagulant, hydrogen peroxide and phosphor in the waste water, by which the waste can be reduced.

Abstract: An apparatus for treatment of fluorine waste water has an introduction tank, a main treatment tank, a calcium hydroxide tank, a polychlorinated aluminum tank, a macromolecular flocculant tank, a settling tank, and a concentration tank. Fluorine waste water is introduced through the introduction tank into a lower part of the main treatment tank through a lower inlet pipe. Also, return sludge from the concentration tank and silicon sludge from a silicon waste water treatment system are introduced into an upper part of the main treatment tank. Thus, silicon recovered from silicon waste water is recycled for treatment of fluorine waste water. Also, unreacted chemicals, which have been loaded in the calcium hydroxide tank, polychlorinated aluminum tank, macromolecular flocculant tank, are recycled. The main treatment tank has no stirrer, and thus conserves electrical energy, but can neutralize the waste water.
