An apparatus and method for separating water from an oil-and-water mixture includes at least two elongated separator vessels oriented at an incline and connected to one another so that an upwardly flowing oil predominant fluid passes from the first separator vessel to the second separator vessel where further electrostatic separation of water from the oil predominant fluid occurs. Each vessel has an electrode at its upper end preferably connected to a different voltage source. The inlet to each vessel is located relative to the electrode to provide an up flow or a down flow vessel. Additionally, the first vessel may be at a different elevation than the second vessel. An additional vessel may be included with output from the first vessel bypassing the additional vessel, the second vessel, or both. Baffles may be added in the water collection portion of each vessel to reduce turbulence and settling distance. |

Systems and methods for processing sludge from a fume scrubbing system that scrubs fumes from a steelmaking converter in a manner that separates/isolates a significant portion of the metallic iron particles in the sludge and prepares these particles for convenient handling. In an exemplary system, the system includes separating equipment that isolates metallic iron particles in the sludge and forming equipment that forms the isolated particles into briquettes that have relatively high mechanical resistance that allow the briquettes to maintain their integrity during handling and storage. The high-metallic-iron-content briquettes can be recycled in the steelmaking process, for example, as charging material for a basic oxygen converter or an electric arc furnace. Water used in the system can be recycled and reused within the system, thereby making the system environmentally friendly. |

A system providing selective spin modification and reaction in an electrolytic cell. An electrolytic cell is coupled to a magnet that provides a level-splitting magnetic field in a region of electrolyte adjacent to a working electrode, thus establishing a spin resonance for an unpaired electron associated with a chemical species in the region of electrolyte adjacent to the working electrode. The working electrode carries an excitation current produced by a switching source or amplifier. The excitation current produces an alternating magnetic field adjacent to the working electrode that alters the spin state population density for the unpaired electron associated with a chemical species within the electrolyte, thereby enhancing or inhibiting the reaction of the chemical species during subsequent electrolysis. |

A method for sorting nanoobjects from the mixture comprising nanoobjects such as semiconducting and metallic carbon nanotubes and an apparatus fabricated thereby. An embodiment comprises an energy transfer to the mixture in a way that the degree in which nanoonobjects are heated and bonded to the surface of a substance depends on their electrical conductivities. The next embodiment comprises an electrolytic deposition of a material on the mixture in a way that the degree in which nanoanobjects are bonded to the surface of the substance by the deposited layer depends on their electrical conductivities. The above nanoobjects are sorted by selectively separating mostly the weaker bonded nanoobjects from the surface. Another embodiment comprises an energy transfer in a low pressure reactive gas medium to the mixture in a way that the degree in which nanoonobjects are heated and chemically modified depends on their conductivities. |

A vertical electrostatic coalescer comprises a first and second electrode surface and a horizontally disposed foraminous surface. The first electrode surface and horizontally disposed foraminous surface are at ground potential. The first and second electrode surfaces share the same planar orientation relative to the central longitudinal axis of the vessel. The unique arrangement of the vessel and opposing pairs of first and second electrode surfaces provides for a substantially uniform voltage field around a perimeter of the vessel and an effective voltage field for coalescence within a center of the vessel. A circular-shaped distributor pipe or a distributor housing serves to absorb momentum of the incoming emulsion stream and distribute the stream into an interior of the vessel. |

The objective of this research is to model and design a microfluidic system that uses electrostatic fields to induce movement of discrete droplets of solution. Of particular interest is movement of droplets of H2O for use in biological testing with lab-on a-chip and μTAS systems. Using computer modeling, the electric-fields for planar electrode configurations positioned on an insulating substrate are calculated for a hemispherical drop of H2O on the substrate at various positions. From these electric-fields the force on the drop is calculated. These models show that electrostatic actuation of droplets of H2O is possible. However, as the complexity of the model increases the properties of the system become less desirable and actuation may not be possible. Using microfabrication techniques, the modeled microfluidic systems have been built for testing using a Kapton substrate with copper electrodes. Hexadecenyltrichlorosilane (HTS), a self-assembled monolayer, and its oxidant have been studied and found capable of providing hydrophobic and hydrophilic surface coatings for the systems. |

An apparatus and method of producing and using aluminum slurry containing aluminum particles having an extremely small size. In particular, a particle size that is small enough to freely flow through water filtration filters. Once the aluminum particles react with phosphorus, phosphates, and other contaminants, the resulting particles are large enough to be trapped by filters such that the contaminants can be easily removed. The aluminum slurry is created by the use of a unique process which rapidly transforms electrically charged aluminum plates into slurry. The resulting slurry is then added to the body of water where it disperses throughout the water and flocculates with the contaminants. The resulting clumps produced by the reaction are large enough to be trapped by filters in the water treatment facility. |
