  • Patent number: 9463398
    Abstract: A bubble removal method removes a bubble from liquid whose viscosity is reduced when shear occurs. A vessel whose volumetric capacity is variable is used. The interior of the vessel is depressurized and pressurized by increasing and decreasing the volumetric capacity of the vessel from a plurality of locations. As a result, the volume of the bubble is increased and decreased and the bubble is caused to move and be removed.

    Abstract: A method for treating an aqueous effluent comprising at least one dissolved gaseous compound, by partially separating said compound from said effluent, in order to obtain a treated aqueous phase. In the method, an upflow liquid column of the aqueous effluent is established by injecting and distributing into said column, at the bottom, a gas phase less rich in said compound than the aqueous effluent, for example air or oxygen, said gas phase being distributed in the column in the form of bubbles where the volume increases upward. A mixed liquid/gas stream is obtained at the top. The mixed liquid/gas stream is then separated into a liquid stream constituting the treated aqueous phase, and an offgas stream enriched with said gaseous compound, where the mixed liquid/gas stream is later separated under vacuum by establishing a gas headspace between the liquid stream and the gas stream, and by aspirating the latter.

An apparatus is provided for defoaming, comprising: a vacuum system, including a vacuum head for drawing the foam through a suction hose terminating in a nozzle, that feeds the foam into a holding tank that initially stores a quantity of defoaming agent, and a pump drawing the defoaming agent from the holding tank to at least one injector that is fitted on the vacuum-side of the vacuum system, whereby the defoaming agent is actively mixed with the collected foam, reducing the collected foam. The reduced foam and defoaming agent are recirculated through the pump and the nozzle, the suction hose, the vacuum system, the injector and holding tank are of chemical-resistant construction.

  • Publication number: 20080314247
    Abstract: A liquid foam system and process for treating an aqueous medium volume includes foam breaking equipment for treating foam floating on a liquid medium. The foam breaking equipment includes a foam conveyer, a rotatable driven screw for sucking foam present in the foam conveyor and for causing at least a partial defoaming of the foam and for expelling foam out of the foam conveyor, and an exhaust gas tube for removing gas within the foam conveyor released from the foam during defoaming. The foam breaking equipment may be used in conjunction with a first tank having a liquid medium and the process includes conveying foam downwardly into the foam conveyor and at least partially defoaming the conveyed foam.

  • Patent number: 7232476
    Abstract: An apparatus for scum removal is disclosed wherein toothed paddle induces turbulent effect on the fluids present in the reactor by means of its rotary motion. This results in both breaking and radial displacement of the scum, accumulated on the fluid during the course of the biochemical or chemical reaction, towards the outlet of the reactor, thereby ensuring that the reaction continues in scum free environment uninterruptedly.

  • Patent number: 6969419
    Abstract: A method for removing bubbles adhering to the interior wall of a fluid-filled chamber through which a fluid flows, and a related method and apparatus for removing bubbles from a chamber having medical sensory equipment such as a blood gas and chemistry analyzer. The method includes drawing a quantity of gas into the chamber to empty the chamber of fluid, maintaining the chamber in an empty state for a predetermined period of time, and then refilling the chamber with fluid at a rate low enough to remove remaining bubbles and to prevent the formation and trapping of new bubbles within the chamber.

  • Patent number: 6800116
    Abstract: Discloses apparatus and method to deaerate and condition bitumen froth obtained from a primary tar sands bitumen extraction process comprising a vessel containing a plurality of inclined plates, called a static deaeration conditioner. The inclined plates of the static deaeration conditioner are substantially equidistantly spaced from each other and are inclined at an angle to the horizontal. The plates form a corresponding plurality of channels there between for the froth to be deaerated to flow along. The declination angle is selected to obtain a gravity induced froth flow rate in the channel that exhibits a lamella effect near laminar flow characteristics, which promotes the creation of a water-enriched froth region near the lower plate of the channel. A braking pump can be provided on an outlet port of the vessel to control the rate of flow through the vessel of the froth to be deaerated and conditioned.
