  • Patent number: 8097167
    Abstract: The present invention relates to a process of concentrating an aqueous suspension of solid particles comprising the steps of adding at least one organic polymeric flocculant to the suspension thereby forming flocculated solids in which the flocculated solids are allowed form a layer of solids and thereby forming a more concentrated suspension in which the process comprises the addition of an effective amount of an agent that is selected from the group consisting of free radical agents, oxidising agents, enzymes and radiation, in which the agent is applied to the suspension prior to or substantially simultaneously with adding the organic polymeric flocculant and/or the organic polymeric flocculant is added to the suspension in a vessel and the agent is applied to the suspension in the same vessel. The process is particularly suitable for solids liquid separation in which the flocculated solids are allowed to settle by sedimentation in a gravity thickener.

  • Patent number: 8092688
    Abstract: A method for treating water in a ballasted flocculation system comprises directing water into a ballasted flocculation zone and adding ballast and a flocculation reagent to the water to form a water-floc mixture. The water-floc mixture is directed into a settling zone to form treated water and sludge containing ballast. The ballast is then directed to a recirculation line where the ballast is recirculated to the ballasted flocculation zone. The method further includes determining the ballast concentration and comparing the ballast concentration with a predetermined threshold value. The rate at which ballast is recirculated to the ballasted flocculation zone is adjusted based on the determined ballast concentration and the predetermined threshold value.

  • Patent number: 8080166
    Abstract: A multiphase separation system utilized to remove contaminants from fluids includes a pre-filtering module for filtering a contaminated fluid to provide a filtered contaminated fluid. A condenser module receives the filtered contaminated fluid and a contaminated gas phase for condensing the contaminated gas phase to a contaminated liquid. A phase reaction chamber converts the filtered contaminated fluid to a contaminated mist wherein the mist is subjected to a low energy, high vacuum environment for providing a first change of phase by separating into a contaminated gas phase and a liquid mist phase. The contaminated gas phase is carried out of the phase reaction chamber by a carrier air. A vacuum pump provides the low energy, high vacuum environment in the phase reaction chamber and delivers the contaminated gas phase to the condenser module for condensation providing a second change of phase.

  • Patent number: 8062529
    Abstract: A method for treating water includes directing untreated water into a mixing zone in a water treatment system and mixing the untreated water with a flocculating agent and a ballast to form a ballast-floc mixture. Thereafter, the ballast-floc mixture is directed to a settling zone where the mixture settles to form sludge. Treated water is discharged from the settling zone and the sludge is directed to a separator. The method further includes separating at least a portion of the ballast from the sludge and directing the separated ballast from the separator to the mixing zone. Finally, the sludge is directed from the separator to a sludge treatment reactor where at least some of the remaining ballast settles from the sludge and substantially ballast-free sludge is discharged from the sludge treatment reactor.

  • Patent number: 8062517
    Abstract: A method and system for removing from an aqueous system which is contaminated therewith: (1) mercury present as colloids, ions and/or organically bound compounds, and (2) hydrocarbons solubilized, dispersed, and/or emulsified in the said system. Pursuant to the invention the aqueous system to be treated (such as “produced water”) is passed successively through three filtration stages. The first filtration stage is provided with absorption media which effects reduction/removal of dispersed organically bound mercury species and of the dispersed and partially dissolved hydrocarbon phases, as well as of some colloidal mercury and other dissolved metallic species. The second filtration stage utilizes a salt modified reticulated granular filtration media for reduction/removal of slightly dissolved hydrocarbon phases, mercury in colloidal and ionic form and other dissolved metals.
