摘要： Mineral particles consisting essentially of metallic magnesium particles subjected to special processing are accommodated directly in a microporous cartridge made of a sintered polypropylene material, and the cartridge is closed. The cartridge is put in a closed raw water container, whereby a large amount of hydrogen gas is generated in a short period of time and released from the whole surface of the cartridge in the form of microbubbles so as to be dissolved in raw water in the container.

摘要： Contemplated devices and methods for arsenic recovery employ a two-step process in which an arsenite and arsenate-containing solution is first subjected to a non-electrochemical reduction that reduces arsenate and arsenite. The arsenate-depleted arsenite-containing solution is the subjected to electrochemical reduction at alkaline pH using a cathode with a high-surface carbon portion. Most preferably, the treated solution is then used as eluent for an adsorbent that removed arsenate and arsenite from a water supply.

摘要： A waste stream from energetics processing is treated using a pre-filter having media, preferably sand, and a metal that has a reducing potential, preferably elemental iron (Fe0). The pre-filter is connected to a zero-valent metal column reactor. The waste stream is pumped through the pre-filter to trap solids and deoxygenate it, then enters the reactor and is subjected to a reducing process. Fe0 from the reactor is transformed to the ferrous ion (Fe+2), added to the resultant product, and fed to a continuously stirred tank reactor (CSTR) in which Fenton oxidation occurs. This product is then sent to a sedimentation tank and pH-neutralized using a strong base such as sodium hydroxide (NaOH). The aqueous portion is drawn off and the sludge pumped from the sedimentation tank. Both tanks are monitored and controlled to optimize required additives, while monitoring of pressure drop across the pre-filter and column reactor establishes replacement requirements.

摘要： Compositions in accordance with the principles of the present invention comprise a compressed mixture of fibrous organic materials and multi-valent metals used to remove organic chemical contaminants. The compositions are made into a pre-shaped, compressed form used to form a permeable reactive barrier for decontamination of soils, sediments, sludges, and waters containing environmental pollutants. The compressed mixture, comprising the fibrous organic particles and one or more multivalent metallic particles, is formed into reactive pellets, granules, and other pre-shaped structures for use in constructing a reactive barrier, typically for use in a contaminated environment or in an industrial process. By way of example, the pre-shaped structure may be used to construct a reactive barrier to remove halogenated organic chemical contaminants, nitroaromatic organic contaminants, or certain inorganic contaminants from various terrestrial and aquatic based ecosystems.

摘要： In accordance with the principles of the present invention, fluid is treated with MCM-41 amended with a metallic reducing agent. The iron undergoes anaerobic corrosion and produces hydrogen gas. The hydrogen gas is used at the MCM-41 to carry out dehalogenation reactions. The body of metal containing MCM-41 amended with a metallic reducing agent can be much thinner than conventional bodies of metal and therefore easier to install. In one embodiment the treated fluid can be water while in another embodiment the treated fluid can be a gas. A body of metal containing MCM-41 amended with a metallic reducing agent can be placed below the ground surface to treat contaminated groundwater in-situ. For pumped fluid, in one embodiment treatment units as small in size as a water softener can allow for treatment of relatively high flow rates of pumped contaminated fluid.
