  • Patent number: 8062530
    Abstract: A method for neutralizing brines that contain high levels of silica accompanied with a high pH. Brine is processed through a reactor in which the pH is lowered and the resultant silica precipitate is adsorbed onto a sacrificial crystal structure. The resultant stream is then processed through a solids removal zone wherein the solids are removed and recovered for reuse. The neutralized solids-free brine is then suitable for down-hole injection in the heavy oil industry or further treatment by common water treatment methods if further adjustment is required for other industries.

  • Patent number: 8048309
    Abstract: A method for disposing of carbon dioxide is provided. According to the invention, CO2 is dissolved in seawater and the salinity of the seawater is increased to produce CO2-containing brine. The CO2-containing brine is denser than the seawater from which it is made. Therefore, when it is released into the ocean, the CO2-containing brine sinks to depth and sequesters the carbon dioxide. The brine may be produced by forming CO2 hydrate, which extracts fresh water from the seawater. Alternatively, the brine may be produced by forming water ice from the seawater and injecting CO2 into the seawater either before or, more preferably, after the water ice has been formed.

  • Patent number: 8034238
    Abstract: A multi-chamber basin is sized to collect excess waste water exceeding the processing capacity of a sewage system. In order to disinfect the waste water exceeding the basin capacity, disinfectant is added at a point in the system after the first basin. After the rain event is over and there is excess sewage treatment capacity, the sewage treatment in the multi-chamber basin is returned to the sewage system. By not disinfecting the waste water in the first basin chamber, the overall disinfectant usage can be minimized.

  • Patent number: 8029677
    Abstract: A water purification method and devices, and in particular a purification method effective against microbes, that uses a silane-based antimicrobial, and in particular the AEGIS MICROBE SHIELD antimicrobial, where the antimicrobial is embedded, coated, or otherwise permanently applied to a substrate or carrier, such as a solid, a porous solid, fibers or the like. A volume of microbe contaminated water is exposed to the antimicrobial carrier for sufficient residence time such that sufficient quantities of microbes are eradicated and the water is made potable. The antimicrobial carrier may be an object suspended or placed into a container or reservoir for the water, or the antimicrobial carrier may comprise the container or reservoir itself. Particulate filters or the like may also be combined with the antimicrobial container to remove other undesirable contaminants.

  • Patent number: 8021543
    Abstract: A wastewater treatment system for treating excess wastewater from a sewer system includes a container having first and second portions adapted to receive excess wastewater from the sewer system, and a generally horizontally oriented screen arrangement disposed in the second portion of the container. The system further includes a treating agent dispenser for introducing a treating agent into the wastewater, and an effluent passage in fluid communication with the second portion of the container. During a sufficient rain event, the wastewater flows from the sewer system into the container, through the screen arrangement, and then into the effluent passage, such that the wastewater flows generally in a first direction through the first portion of the container, then generally in a second direction different than the first direction through the second portion of the container.

  • Patent number: 8021556
    Abstract: A method is provided for clarifying wastewater containing contaminants including soluble organic compounds and insoluble organic compounds. The wastewater is treated with a paculant admixture including a cationic coagulant polymer and powdered activated carbon. The cationic coagulant polymer is polydiallydimethylammonium chloride, poly quaternary amine, and/or a starch-based organic polymer. After an at least 2 second delay, a flocculent is added to the wastewater to achieve (i) microcoagulation of the cationic coagulant polymer with the contaminants to form coagulated particles having an effective mass and cationic charge to react with an anionic flocculent to be added thereafter, and (ii) absorption of the soluble organic compounds on the powdered activated carbon. The anionic flocculent as added and reacted with the coagulated particles to form a sludge, containing agglomerated particles including the coagulated particles and powdered activated carbon, of sufficient size for mechanical removal.

  • Patent number: 8017001
    Abstract: The disclosed systems and methods for maintenance of an enclosed body of water generally include mobile systems and/or methods for removal of mineral hardness and other particulate impurities via lime softening filtration. Chemicals are added to a body of water containing unwanted mineral hardness (or other particulate impurities) and mixed to assist dispersion. The chemicals react with the hardness minerals making them insoluble. The resulting precipitate falls out of solution to the bottom of the body of water for subsequent removal via filtration. This eliminates or otherwise reduces the need for draining water and/or adding new water to a body of water to maintain proper mineral hardness balance and/or concentration of other particulate impurities.

  • Patent number: 8012347
    Abstract: A device for separation of fluid, in particular oil, gas and water, in connection with the extraction of such a fluid from formations under the surface of the earth or the sea bed. The fluid is transported in a supply pipe or transport pipe (4) to a separator (1) in the form of a tubular separator body, a gravitation tank or similar. The separated components, water and oil, are passed out of the separator separately via outlet pipes. The fluid upstream of the separator (1) is subjected to shear forces so that the drops in the supply flow are torn up to form drops that are so small that the interface generally becomes new and “uncontaminated” by surfactants. The shear forces are supplied by a phase inversion device (6) in the form of a valve or similar. Water can expediently be added to the fluid upstream of the phase inversion device (6) to achieve the desired phase inversion.
