  • Patent number: 10035089
    Abstract: The present invention presents a filtration system with an integrated manifold valve. The filtration system employs only one pivotal component—the pivoting of the manifold. The manifold valve includes a dual aperture design for a two-fold alignment scheme with the ingress and egress lines of the fluid source. The invention is free of multi-component rotary valve with internal, rotatable parts, or an activation component, such as a handle, for initiating the rotary valve, allowing the user to rotate the rotational components thereof. The reduction in moveable components in this design reduces the likelihood of failure and increases the reliability of the filtration system.

  • Patent number: 8940159
    Abstract: The invention includes a method for the optimization of the soluble CO2 concentration in the aeration basin of an activated sludge system, which significantly improves the specific growth rate of the nitrifying bacteria. The result is a reduction in capital and energy costs for municipalities. The rate of nitrification is a product of the nitrifying bacteria biomass concentration and the specific growth rate of the bacteria. In the activated sludge system, the biomass concentration is maintained at high concentrations by reducing the wasting rate. The specific growth rate is a function of the ammonium concentration and the environmental conditions. Here, the inventors show that growth of nitrifying bacteria is inhibited when the soluble CO2 concentration is elevated beyond certain parameters. Elevated soluble CO2 concentration also reduces the pH, which also impacts the rate of growth of nitrifying bacteria.

    Abstract: A horizontal flow water treatment method and wetland biofilter apparatus provides a chamber with impermeable outer walls spaced away from permeable interior walls of a media filtration bed such that a catch basin is formed between the outer walls and the interior walls. The catch basin creates an open area around the perimeter of the interior walls for influent water to fill within the open area before penetrating the filtration media, providing a large surface area for influent water to interact with the media filtration bed. The influent water enters the catch basin in a horizontal flow path to provide for pre-settling of particulates before making contact with the filtration media. The biofilter design increases the available surface area of the media filtration bed by up to four times for a given volume of water, and thereby minimizes the loading or infiltration rate on the media filtration bed.

    Abstract: Provided are a process and device for reducing radioactive material of an object containing the radioactive material to a safe level in a living environment. Included are a step of performing at least a step of carrying out a heating process on the object, into which radioactive material is absorbed and/or adsorbed from an environment or which absorbs and/or adsorbs radioactive material from an environment, in a state where temperature is less than or equal to the critical temperature of water and pressure is greater than or equal to the saturated vapor pressure of water, or a step of abruptly releasing the pressure; and a step of separating, after the above step, into liquid and solid.

  • Publication number: 20140217037
    Abstract: Methods for producing or regenerating an iodinated resin are presented. The methods include converting iodide residues on a surface of and in pores of an iodide loaded anion exchange resin to iodine and iodine intermediates using a source of active halogen to form an iodinated resin having iodine and iodine intermediate residues on the surface of and in the pores of the iodinated resin. The iodinated resins show reduced and stable levels of iodine elution compared to conventional iodinated anion exchange resins and may utilizes less iodine raw materials during the manufacturing process. The iodinated resin can also act as an end-of life indicator in a water purification system that incorporates the iodinated resin to reduce microbial, including bacterial and viral, contamination in drinking water sources. Methods and systems for purifying water are also presented.

  • Publication number: 20140217027
    Abstract: Systems and methods for controlling fluid movement and volumes of fluid between a subject and a controlled compliant flow path. The controlled compliant flow path has a means for selectively metering in and metering out fluid from the controlled compliant flow path. An extracorporeal flow path is in fluid communication with the controlled compliant flow path across a semi-permeable membrane where the extracorporeal flow path has a first terminal end and a second terminal end.

  • Patent number: 8771515
    Abstract: A horizontal flow water treatment method and wetland biofilter apparatus provides a chamber with impermeable outer walls spaced away from permeable interior walls of a media filtration bed such that a catch basin is formed between the outer walls and the interior walls. The catch basin creates an open area around the perimeter of the interior walls for influent water to fill within the open area on all sides before penetrating the filtration media, providing a large surface area for influent water to interact with the media filtration bed. The influent water enters the catch basin in a horizontal flow path to provide for pre-settling of particulates before making contact with the filtration media. The biofilter design increases the available surface area of the media filtration bed by up to four times for a given volume of water, and thereby minimizes the loading or infiltration rate on the media filtration bed.

  • Patent number: 8759251
    Abstract: A treatment medium has a particulate natural substrate saturated, suffused and/or coated with hydrous iron oxide. The particulate substrate can be wood based, such as wood chips, bark, sawdust, wood waste or other plant material (such as straw, lucerne, hay, coconut husk or other bulk particulate plant material). The hydrous iron oxide is provided in aqueous suspension form. The substrate may be tumbled in aqueous hydrous iron suspension to achieve saturation/coating. The resulting hydrous iron oxide bearing medium is either placed loose directly into the target treatment site or contained in bags 18 before placing into the target site.
