  • Patent number: 8715498
    Abstract: A polymer-free method and self-draining self-cleaning apparatus for treatment of water with high total dissolved solids including optional pretreatment, precipitation/flocculation, and separation. The pH is raised by addition of caustic soda and/or soda ash. In a vertical clarifier silo, the feed is gently mixed to cause dissolved solids to precipitate and agglomerate to form suspended flocculates. The clarifier includes an internal mixer surrounded by a cylindrical tube diffuser. Rotation of the mixer provides gentle dual circulation patterns within the clarifier that allow for flocculates of a predetermined size to settle from suspension. The clarifier may also include one or more vertical recirculation lines to recirculate some of the heavier flocculates at the bottom of the vessel into the mixer chamber to enhance precipitation via the seeding effect. The suspended flocculates are stripped from the feed water in a centrifugal separator. The clarifier silo may be trailer mounted for rapid deployment.

  • Patent number: 8192631
    Abstract: An apparatus and method for treating raw water. The apparatus includes a vessel having an inlet for the raw water, an outlet for the skimmed water, a rotor mechanism for creating a plurality of gas bubbles within the raw water, and a disperser device operatively associated with the rotor mechanism for dispersing the plurality of gas bubbles from the rotor mechanism within the vessel. The vessel contains raw water. The gas bubbles create an oily froth on top of the raw water. The apparatus further includes a skim tray positioned about the rotor mechanism for removing the oily froth from the top of the raw water and a secondary skimmer positioned within the skim tray. An external skim tank may be configured to deliver a gas to the rotor mechanism and to receive the oily froth from the secondary skimmer.

  • Patent number: 6955763
    Abstract: It has been discovered that a mechanical flotation system having only two cells can be nearly as efficient as one having more cells, yet provide an apparatus with a considerably smaller footprint, significantly reduced capital and operating costs, as well as be resistant to floating oil recovery platform wave effects. The dual-cell mechanical flotation system has, in sequential order, an inlet chamber and two gasification chambers or cells, each with at least one gas ingestion and mixing mechanism, and a discharge chamber. A common primary skim collection channel atop the partition dividing the gasification chambers efficiently channels away the bulk of the floating collected matter. At least one baffle depending from the top of the vessel near the primary skim collection channel helps dampen the action of the fluid containing the suspended matter when the vessel is affected by wave motion against the floating oil production platform.
