  • Publication number: 20090293721
    Abstract: A dispersion apparatus for dispersing a treating agent into a fluid treatment system that includes a flow duct in which a fluid stream flowing through the duct is mixed with the treating agent. The apparatus is based on a multi-pipe lance positioned in the stream flow, where each pipe supplies a minimum of feed discharge nozzles (typically one to four), and the individual pipes branch off from the same location. Use of the multi-pipe lance, in combination with a suitable baffle, results in better overall dispersion/distribution of the injected medium by surface area. By improving the surface area distribution, better utilization of the injected sorbent can be achieved. The baffle acts to generate a low pressure zone on its downstream side and creates a high-intensity turbulence plume in the fluid. The orifices of the pipe are located to inject the treating agent into the turbulence plume to better distribute and intermix the injected treating agent into the surrounding fluid.

  • Patent number: 7022509
    Abstract: A method for removing a gas from a site comprising placing cells having gas vesicles under conditions that induce the cells to float to a surface of an aqueous medium, harvesting the cells from the surface of the medium, lysing the cells, separating the gas vesicles from the lysed cells, crosslinking the gas vesicles with a crosslinking agent, loading a gas with a lowered partial pressure for the compound to be removed into the gas vesicles, and placing the gas vesicles such that the gas compound is removed from the site. Harvesting gas-vesicle-containing cells is achieved by placing the cells under conditions that induce the cells to rise to the surface of an aqueous medium—such as darkness, exponential growth stage, flocculation, or dissolved gas flotation—then collecting the cells from the surface of the medium. Gas vesicles are isolated by lysing the cells and separating the gas vesicles from the lysate. Once the gas vesicles are isolated, they can be modified, such as by crosslinking with glutaraldehyde.

  • Patent number: 6699389
    Abstract: A method for removing contaminants from water involves filtering the water through a filtering apparatus which includes a porous media container having an inner chamber which is suitably configured so that water can pass through the chamber and processed straw retained within and suitably within the chamber such that when water passes through the chamber, it also passes through the straw. A method is provided for enhancing the composting (470) of organic matter, e.g., sludge, including the steps of adding processed straw to a compost mixture and digesting said mixture.

  • Patent number: 6592763
    Abstract: A novel method for purifying, by means of an essentially closed circuit water purification system, an aqueous flow from a processing unit includes the steps of: (a) supplying to a bioreactor, and combining therein, the aqueous flow, as well as a discharge flow from a membrane filtration unit; (b) allowing microbiological conversion of biodegradable constituents to take place therein, thereby, generating an effluent flow; (c) supplying the bioreactor effluent flow to an ultrafiltration unit, thereby, separating the effluent flow into permeate and concentrate flows; (d) supplying at least some of the permeate flow to a membrane filtration unit, thereby, generating a product flow and the discharge flow; and (e) supplying the discharge flow to the bioreactor, as noted in step (a), and supplying at least a portion of the product flow to the processing unit. Apparatus related thereto are also disclosed.

  • Patent number: 6586181
    Abstract: A method for detecting allelic imbalance (AI) in sample nucleic acid, which method comprises providing multiple copies of a target nucleic acid region present in the sample, the target nucleic acid region comprising a marker of heterozygosity, separating the multiple copies into individual strands then allowing the individual strands to reanneal under conditions which permit the formation of homoduplexes and heteroduplexes, removing any heteroduplexes so formed, subjecting the remaining homoduplexes to the above steps of separation, reannealing and heteroduplex removal one or more times so that any difference in the initial ratio of allelic variants is amplified, and detecting the presence or absence of AI by reference to any difference in allele ratio so detected.

  • Patent number: 6573087
    Abstract: An absorbent package for containment and bioremediation of hydrocarbons and method thereof are disclosed. The package comprises a concentration of microorganisms, a timed release mechanism including a time release capsule, a matrix of fibrous material which is hydrophobic and oleophilic, and a porous casing. The fibrous material may be selected from synthetic fibers and cellulose fibers for storing accumulation of hydrocarbons. The method includes positioning a concentration of microorganisms capable of degradation of the hydrocarbons. Further, the method also provides the matrix which is absorbent, and such method includes filling the casing with the matrix and the microorganisms to form a hydrocarbon containment and degradation package. Then the method employs the action of absorbing and storing hydrocarbons passing through the casing and wicking hydrocarbons via capillary action through the matrix and absorbing the hydrocarbons into the matrix.
