摘要： An apparatus and process for recovering metals from aqueous solutions by passing an aqueous solution, which contains dissolved metals, into a space between two elongated electrodes of a treatment chamber. A very high voltage electric field is created in the treatment chamber and is accompanied by a very small trickle current charge to enhance adsorption, polarization, ion exchange or to otherwise agglomerate the dissolved metal, which is then recovered by filtering, adsorbing, exchanging or otherwise separating the metal from the water.

摘要： Methods and compositions for removing perchlorate and/or nitrate from contaminated material utilizing a DM-17 bacteria. DM-17 is a gram-negative, motile, polymorphic, facultative anaerobe which is deposited with the American Type Culture Collection under ATCC No. PTA-2685. DM-17 may be used as a substitute for anaerobic bacteria which are presently being used in biological systems for removing perchlorate and/or nitrate from water and other contaminated materials, such as soil. Enhancement of nitrate reduction results from the presence of a level of perchlorate. Enhancement of perchlorate results from the presence of a level of nitrate. Particular carbon contributors further enhance remediation.

摘要： Electropurification of contaminated aqueous media, such as ground water and wastewater from industrial manufacturing facilities like paper mills, food processing plants and textile mills, is readily purified, decolorized and sterilized by improved, more economic open configuration electrolysis cell designs with electrodes comprising a plurality of conductive porous elements in electrical contact with one another. The cells may be divided or undivided, and connected in monopolar or bipolar configuration. When coupled with very narrow capillary gap electrodes more economic operation, particularly when treating solutions of relatively low conductivity is assured. The novel cell design is also useful in the electrosynthesis of chemicals, both organic and inorganic types, such as hypochlorite bleaches and other oxygenated species.

摘要： A water treatment arrangement is provided in which water is given a reduced pH by a first catalyst and then is caused to flow over a second catalyst that changes nitrates, nitrites, phosphates, salts and other contaminants from reactive to nonreactive form. The first catalyst may be palladium and the second catalyst an alloy containing copper, tin, nickel and zinc. The first catalyst prevents precipitants from coating the second catalyst and also increases the supply of oxygen in the water. Preferably, a third catalyst, also palladium, is included downstream of the second catalyst. The first and third catalysts include longitudinal vanes having louvers to present a large surface area and create turbulence. The second catalyst is a tubular assembly with ribs and grooves also to create turbulence and removal of the stagnant boundary layer from the catalyst's surface. The catalysts are in an end-to-end abutting relationship within a housing of corrosion-resistant material.
