  • Patent number: 10603636
    Abstract: A multistage desalination process for treatment of seawater or salt wastewater. During initially processing the seawater or salt wastewater is treated to precipitate scaling minerals as phosphates including magnesium ammonium phosphate useful as a fertilizer. During the initial phase, ammonium phosphate and sodium phosphate are added to the seawater or salt wastewater followed by an addition of ammonia and a water-based charged solvent. After separating the precipitated solids, the cleaned seawater or salt wastewater is aerated and filtered to produce potable or otherwise usable water.

In a treatment method for radioactive strontium-containing wastewater, wastewater containing radioactive strontium and a powdery alkali metal titanate are mixed in a stirrer-equipped reaction tank by stirring such that radioactive strontium in the wastewater is adsorbed on the powdery alkali metal titanate, followed by subjecting the powdery alkali metal titanate having radioactive strontium adsorbed thereon to solid-liquid separation. The radiation dose of treated water can be effectively reduced in such a manner that a powder of an alkali metal titanate is directly added to radioactive strontium-containing wastewater and is dispersed therein and therefore radioactive strontium is efficiently removed by adsorption.

  • Publication number: 20140346114
    Abstract: Flow and product waste water from fracturing can be cleaned and reused utilizing a precipitation methodology incorporating, in part, a super critical reactor 30. Initially, the waste water is treated to remove solids, destroy bacteria, and precipitate out certain salts, such as barium, strontium, calcium, magnesium and iron. The waste water then can be passed through a radioactive material adsorption unit 20 to remove radium, as well as other radioactive materials, and then introduced into the super critical reactor 30. The super critical reactor is designed to bring the waste water to super critical conditions at a central portion of the reactor. This causes any dissolve solids, in particular sodium chloride and the like, to precipitate out of solution in the center 42 of the reactor 30 thereby avoiding scale formation on the walls of the reactor. A catalyst can be utilized to promote the breakdown of carbon bonds and promote the water/gas shift reaction.

    Abstract: An immiscible lipophilic or hydrophilic liquid phase separated respectively from a continuous hydrophilic phase or a lipophilic phase liquid. Fibers having hydrophilic and hydrophobic properties are formed into a filter. The separation mechanism involves capture of small droplets of the immiscible phase, coalescence of the small droplets into larger droplets as the immiscible liquid flows through the fiber filter, and release of the large immiscible droplets from the filter. Regarding separation of a hydrophilic immiscible fluid such as water in a lipophilic continuous fluid such as oil, the hydrophobic fibers cause small water droplets to migrate towards the hydrophilic fibers whereby large droplets form on hydrophilic surface. The large droplets stay on hydrophilic fiber surface for extended periods of time and continue to coalescence until they are so large that they can no longer be maintained by the hydrophilic fibers and are released and drained off of the filter.

One solution can involve heating the wet biomass with a heating unit to a pre-treatment temperature sufficient for organic constituents in the feedstock to decompose, for precipitates of inorganic wastes to form, for preheating the wet feedstock in preparation for subsequent removal of soluble sulfate contaminants, or combinations thereof. Processing further includes reacting the soluble sulfate contaminants with cations present in the feedstock material to yield a sulfate-containing precipitate and separating the inorganic precipitates and/or the sulfate-containing precipitates out of the wet feedstock. Having removed much of the inorganic wastes and the sulfate contaminants that can cause poisoning and fouling, the wet biomass feedstock can be exposed to the heterogeneous catalyst for gasification.

  • Publication number: 20140001120
    Abstract: In an apparatus for treating wastewater, e.g sewage water, the water passes through a standard treatment process stream to promote production of dissolved reactive phosphate ions (PO4). Iron (or aluminum) ions are generated by electrochemical means and added to the process stream at one or more locations to produce metal-P coagulant solids removed in part by pump-out, with the substantial remaining P removed by mineralization and filtration in a biological filter such as a sand filter or leach field. In another apparatus, the water passes through a standard aerobic treatment process stream to promote production of dissolved reactive phosphate ions. Iron (or aluminum) ions are generated by electrochemical means and added to the process stream at one or more locations to produce a flocculant of Fe—P minerals that are separated out by sedimentation, physical filtration or magnetic means.

  • Publication number: 20130319947
    Abstract: The invention relates to a process and apparatus that treats waste water, in particular waste water containing surfactants and including grey water, for local reuse. According to the invention, the process comprises a) collecting waste water in a reservoir; b) injecting gas into waste water from the reservoir to form bubbles in the waste water; c) separating the bubbles, and any entrained contaminants, from the waste water; d) drying the separated bubbles and returning any water recovered from the dried bubbles to the waste water undergoing treatment; e) optionally repeating steps b) to d) to achieve the desired purification of the waste water; and f) collecting the purified waste water.

  • Publication number: 20130292336
    Abstract: The present invention is a wastewater treatment method using dried BOF slag and hydrogen peroxide, wherein hydrogen peroxide is oxidized to generate hydroxyl radicals that reacts with soluble metal contaminants in the sludge such that these contaminants can be adsorb on the catalyst particles and/or eliminated from the wastewater stream by separation techniques. The process can use catalytic oxidation for soluble metals removal. In addition, catalytic oxidation can produce a filtered water saturated with Oxygen and higher in pH resulting in enhanced precipitation of soluble metals when softening agents, such as Sodium Carbonate, are added in a subsequent processing step. Another embodiment of the present invention is a method using ferrous sulfate for removing soluble metals in wastewater, followed by Catalytic Oxidation to remove soluble Fe without addition of metal salts, and removing sulfates by adding Barium Carbonate.

  • Patent number: 8532829
    Abstract: A controller for water treatment in a cooling system includes a processor, a user interface, a plurality of relays, at least one network port, and at least one communication port. The processor is configured to monitor cooling fluid in the cooling system and cause the system to drain fluid when an amount of dissolved solid in the fluid exceeds a predetermined threshold. The plurality of relays are configured for both wet operation and dry operation. The controller is accessed using a web server on the controller through a communication port. The controller is controller and control parameters are modified via the web server. A relay of the plurality of relays in the controller is configured for either wet operation or dry operation. The configuration of the relay of the plurality of relays is dynamically changed to the other of wet operation or dry operation.

  • Patent number: 8500847
    Abstract: A gold thiosulfate leaching process uses carbon to remove gold from the leach liquor. The activated carbon is pretreated with copper cyanide. A copper (on the carbon) to gold (in solution) ratio of at least 1.5 optimizes gold recovery from solution. To recover the gold from the carbon, conventional elution technology works but is dependent on the copper to gold ratio on the carbon.
