Abstract:
There is provided an electrophoresis device. The device includes a chamber, for containing liquid medium, the liquid medium including a flowing separation medium, carrying a sample, a pair of opposing electrodes for generating an electric field, with effect that the generated electric field effects spatial separation of the sample into sample fractions and, with respect to at least one of the electrodes, also effects generation of gaseous material from the liquid medium disposed at, or substantially at, an operative electrode surface of the electrode, with effect that the generated gaseous material becomes, at least initially, disposed within the liquid medium, wherein the generated gaseous material includes at least one generated gaseous compound, and at least one outlet for collecting a sample fraction. In some embodiments, for example, the device further includes a gas separator for inducing removal of at least a fraction of the generated gaseous material from the chamber, the gas separator including a space configured for effecting fluid communication between the liquid medium and a generated gaseous material receiving fluid phase such that a fluid interface is defined between the liquid medium and the generated gaseous material receiving fluid phase, and such that at least a fraction of the generated gaseous material migrates upwardly from its disposition at, or substantially at, the operative electrode surface to the fluid interface in response to buoyancy forces, and then from the fluid interface and into the generated gaseous material receiving fluid phase in response to a driving force. In some embodiments, the device further includes flow guides, disposed between the electrodes, for directing the flowing separation medium towards the at least one outlet. In some implementations, the flow guides mitigate the creation of a pH gradient.

Abstract:
Decomposition is performed with the application of the method and apparatus by separating solid contaminants from the emulsion, absorbing CO 2 gas in the emulsion, thereby switching the emulsion type from W/O to O/W, pre-heating the emulsion utilizing a heat regenerator (32), setting the stability minimum of the emulsion by adjusting the pH, resolving the emulsion in an electrochemical decomposition reactor (38) by passing it between an anode made of electrochemically active material and a cathode made of electrochemically inactive material, while the colloid particles of the emulsion are bound in flocks forming a foam utilizing as a flocculant the compound produced in situ from the electrochemically active anode, - discharging the foam produced in the above step, and - discharging the decontaminated water through a final settlement tank (47) and/or a final filter (44) and a heat regenerator (32).

Abstract:
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.
