  • Patent number: 11040313
    Abstract: The invention is related to a super-hydrophilic/underwater super-oleophobic attapulgite separation membrane, and a preparation method and use thereof. Monodispersed hydrophilic nanoparticulates are loaded on a surface of nanoparticles, to obtain a super-hydrophilic nanocomposite material with a micro-nanostructure. The nanocomposite material is dispersed in a mixed aqueous solution of polyacrylamide and methyl cellulose, to obtain a membrane-forming slurry after vigorous stirring. A disc-shaped porous support is infiltrated with water and placed on a horizontal surface, and then a certain volume of the membrane-forming slurry is slowly and uniformly drip-coated on a surface of the support, dried and sintered to obtain a super-hydrophilic/underwater super-oleophobic microfiltration membrane layer.

  • Patent number: 11008240
    Abstract: The instant application is directed towards methods for removing sulfide from a wastewater stream. The pH of the wastewater stream is adjusted to between 7.0 and 8.0. A first oxidizing agent is mixed with the wastewater stream, oxidizing the sulfide to elemental sulfur. The wastewater stream is then softened by mixing lime with the wastewater stream. The addition of lime further raises the pH of the wastewater stream to 10.0 or higher, and converts the elemental sulfur to soluble sulfide (S2-) and/or thio-sulfate. Calcium carbonate is precipitated and sulfide (S2-) and/or thio-sulfate is adsorbed thereon. Thereafter, the wastewater stream is directed to a solids-liquid separation process, which separates the calcium carbonate and adsorbed sulfide (S2-) and/or thio-sulfate from the wastewater stream. The solids-liquid separator produces an effluent that includes residual elemental sulfur.

  • Patent number: 10938329
    Abstract: Systems and methods for generating electricity from low grade heat. The system and method may be a closed loop. When a liquid mixture of salt, water, and an ion-stripping liquid is heated using the low grade heat, water dissolves more readily into the ISL, due to the increased solubility of the water in the ISL, at the increased temperature. The salt remains in a high-salinity aqueous phase that separates from the ISL phase. Upon cooling of the ISL phase, a nearly pure water phase can be separated therefrom. This low salinity water phase and the high salinity water phase can be fed to any of various processes for generating electricity from a salinity gradient, such as pressure retarded osmosis or reverse electro-dialysis. Low and high salinity water exiting the power generating portion of the process can be recycled, to reform the original liquid stream, upon recombination with the ISL.

  • Patent number: 10918997
    Abstract: An adjustable filtration assembly performs water filtration tests from a sample point. A container contains a water solution. An inlet valve enables a flow of the water solution into the container. An adjustable pressure regulator valve regulates the flow. A relief valve releases a portion of the water solution when a pressure of the water solution exceeds a threshold pressure. A differential pressure gauge displays a current pressure reading of the water solution in the container, receives adjustments specifying a specific pressure to be maintained, maintains the specific pressure of the water solution, and triggers the relief valve when the pressure exceeds the specific pressure. An outlet valve, when opened, outputs a measured volume of the water solution. A filter membrane mounted in the outlet valve filters solids from the measured volume. A relative plugging index (RPI) of the water solution is determined based on a weight of the solids.

  • Patent number: 10392271
    Abstract: A method for removing hydrogen sulfide from a liquid stream is described. The method includes contacting the liquid stream including a first amount of hydrogen sulfide with a first side of a porous gas-liquid separation membrane. The hydrogen sulfide moves through the pores of the membrane from the first side to a second, opposite side of the membrane. The method further includes contacting a receiving fluid with the second, opposite side of the porous membrane to receive the hydrogen sulfide. The liquid stream is thus converted to a reduced-sulfide liquid stream having a second amount of hydrogen sulfide that is less than the first amount of hydrogen sulfide. A method for removing ammonia from a liquid stream is also described.

  • Patent number: 10358360
    Abstract: In a method for purifying an oil (8)/water (42) mixture (40), the mixture (40) is fed to a container (48) having an ultrafiltration unit (52) with a membrane (30), and a protective material (50) is added to the mixture (40), which protective material, directly or after chemical reaction with the water from the mixture (40), as a film (62) on the membrane (30), keeps free oil (8) away from said membrane. Purified process water for extracting and/or refining of petroleum (8) is thus produced from process water (42) which is contaminated with petroleum (8). A purification device (64) substantially comprises a container (48) having an ultrafiltration unit (52) with a membrane (30), a feed line (28) to the container (48) and an addition device (27) for protective material (50) in the flow path (56) to the membrane (30).
