Chemical Treatment Patents (Class 210/749)
  • Patent number: 10585069
    Abstract: Methods for detection, monitoring, and determination of location of changes in rigid structures with arbitrarily complex geometries are described. Implementations include locating acoustic transducers that generate and receive acoustic signals at multiple locations along a surface of the rigid structure, wherein longitudinal spacing between the transducer locations define measurement zones. Acoustic signals with chosen amplitude-time-frequency characteristics excite multiple vibration modes in the structure within each zone. Small mechanical changes in the inspection zones lead to scattering and attenuation of broadband acoustic signals, which are detectable as changes in received signal characteristics as part of a through-transmission technique. Additional use of short, narrowband pulse acoustic signals as part of a pulse-echo technique allows determination of the relative location of the mechanical change within each zone based on the differential delay profiles.

  • Patent number: 10240311
    Abstract: Methods for reducing the size of an oil slick on a water surface or on a water surface when ice is present are described. Spreading of oil can be reversed by reducing the surface tension of the seawater, for example, by using a low concentration of at least one water-soluble surfactant, such as a non-ionic surfactant. A controlled amount of the surfactant or surfactant mixture may be discharged over time at the inner-wall of a spill control boom surrounding the oil spill, or within the vicinity of the oil spill in the absence of control booms using a soaker hose or a floating polyethylene or polypropylene hose impregnated with surfactant, whereby the confinement and contraction of the oil slick is maintained by compensating for dissolved surfactant and surfactant moving away from the oil slick. Water-soluble surfactants are typically solids or gels at low temperatures when no organic co-solvent is added to the surfactant.

Once a desired concentration of copper ions has been achieved, the concentrated solution is stored in portable vessels for transport to the remote water volume. Concentrated solution is added to the remote water volume to achieve a concentration therein of approximately 0.2-0.3 ppm.

    Abstract: A mobile water re-use system can include a chemical treatment apparatus, at least one weir tank in fluid communication with the chemical treatment apparatus, and two or more settling tanks in fluid communication with each other and at least one of the settling tanks in fluid communication with the weir tank. The weir tank can have a first end, a second end, an internal chamber, and a plurality of baffles that induce turbulent flow of fluid through the internal chamber. The settling tanks can provide, promote, facilitate, result in, and/or induce laminar flow of fluid through at least a portion of the internal chamber. Weir tanks, settling tanks, and method of treating flowback and produced water are also described.

  • Patent number: 8968646
    Abstract: An odor control composition may be dosed to a wastewater treatment system to control hydrogen sulfide levels. The composition may include a sulfide-reducing agent and an oxidizer. Synergy between the compounds of the odor control composition may facilitate efficient reduction of hydrogen sulfide levels. The sulfide-reducing agent and the oxidizer may be present in a single odor control composition or may be dosed to the system separately.

  • Patent number: 8968572
    Abstract: In a device and a process for purifying water which is contaminated with sulphate ions and heavy metal ions, the water is collected in a water reservoir and a substance having basic activity in water is fed to the water reservoir in such a manner that a precipitant having heavy metal ions is precipitated from the water, wherein at least a subquantity of water is taken off from the water reservoir and is separated into pure water which is substantially freed from sulphate ions and heavy metal ions and dirty water which is enriched with sulphate ions and heavy metal ions. The dirty water is at least in part recirculated to the water reservoir, as a result of which a concentration of sulphate ions in the water reservoir is achieved such that a precipitant having sulphate ions is precipitated from the water.

  • Publication number: 20150053626
    Abstract: Implementations of the present invention relate to systems, methods, and apparatus for filtering and treating water, such as tap water, well water, spring water, etc., and producing drinking, bathing, and swimming water. More specifically, such systems, methods, and apparatus can produce purified water by removing substantially all suspended as well as dissolved solids, undesirable acids, gasses and all and any contaminates from the water. Additionally, the systems, methods, and apparatus can produce reprogrammed high biophoton mineralized drinking water by chilling vortexing over proprietary lodestones, ingenious, sedimentary and metamorphic rocks and creating bicarbonate ions in the water introducing minerals and/or salts into the water.

  • Publication number: 20150041411
    Abstract: A preparation including a) at least one N-formal and b) at least one dialkylhydroxylamine. The preparation is preferably formulated as a concentrate. The preparation can be used (in particular in the form of the concentrate) for the reduction of free oxygen and the preservation of water, and also correspondingly additivated water. The mixture of N-formals with dialkylhydroxylamine is not only outstandingly compatible, but considerably improves the activity of dialkylhydroxylamines as oxygen scavengers.

  • Patent number: 8945396
    Abstract: The present invention relates to a delamination method for recovering constituents of a paper-based multi layered laminated packaged waste. The method comprises using of a mixture of inorganic bases to separate the constituents of the packaged waste and recover paper, plastic and/or aluminium components separately. The paper can be recovered as pulp, the plastic can be recovered as is, and the aluminium can be recovered as a water soluble salt. The delamination method of the present invention is also effective on cardboard-based multi layered laminated packaged waste.

  • Patent number: 8945476
    Abstract: A method, apparatus, and system for obtaining a solution from a solid product are disclosed. A solid product is housed in a dispenser. A liquid is introduced into the housing of the dispenser to interact with the solid product to form a solution. To control the concentration of the formed solution, the turbulence of the liquid introduced to the dispenser is controlled and adjusted either manually or on a real time basis to account for varying characteristics of either or both of the solid product and the liquid. The dispenser will adjust the turbulence based on the characteristics to maintain a formed solution within an acceptable range of concentration. The concentrated solution can then be discharged from the dispenser to an end use application.
