  • Biosorption of uranium(VI) from aqueous solution by biomass of brown algae Laminaria japonica

    The uranium(VI) adsorption efficiency of non-living biomass of brown algae was evaluated in various adsorption experimental conditions. Several different sizes of biomass were prepared using pretreatment and surface-modification steps. The kinetics of uranium uptake were mainly dependent on the particle size of the prepared Laminaria japonica biosorbent. The optimal particle size, contact ...

  • Project profile - uranium treatment system Middletown Springs Elementary School Vermont

    Background The Middletown Springs Elementary School in Vermont is located in an area of the U.S. very susceptible to the formation of naturally-occurring uranium. Due to the high levels of uranium detected in the well water serving the School, it was placed on a “Do-not-Drink Advisory”. AdEdge was contacted by Otter Creek Engineering in June 2009 to assist the School in ...

  • Project profile - uranium treatment system village of Marshfield, VT

    Background Following a very successful pilot test, AdEdge Technologies Inc. (AdEdge) was selected in 2007 by the Village of Marshfield, VT and the site’s engineer, Forcier Aldrich & Associates (FA&A), to supply and install a full scale uranium treatment system using its AD92 regenerative Ion Exchange (IX) Technology. Given the high naturally occurring uranium of 76 ug/L ...

  • The costs of power: plutonium and the economics of India's prototype fast breeder reactor

    The Indian Department of Atomic Energy plans to expand nuclear power in the country by constructing a large fleet of plutonium fuelled breeder reactors, seen as necessary because of perceived shortage of uranium resources. We analyse the economics of generating electricity at the first such reactor in India, the prototype fast breeder reactor. We find that such electricity will be 80% more ...

  • Exposure assessment of metal intakes from drinking water relative to those from total diet in Japan

    Daily intakes of 17 metals (boron, aluminium, chromium, manganese, nickel, copper, zinc, arsenic, selenium, molybdenum, cadmium, antimony, lead, uranium, magnesium, calcium, and iron) via drinking water and total diet were investigated in six cities in Japan. The daily metal intakes were estimated and compared with tolerable daily intake (TDI) values proposed by the WHO or Joint FAO/WHO Expert ...

  • Uranium removal by chitosan impregnated with magnetite nanoparticles: adsorption and desorption

    A magnetic biosorbent composed of nanoparticles of magnetite covered with chitosan, denominated magnetic chitosan, was prepared. The magnetic chitosan showed a magnetic response of intense attraction in the presence of a magnetic field without becoming magnet, a typical behaviour of superparamagnetic material. Its adsorption performance was evaluated by the adsorption isotherm models of Langmuir ...

  • Analyzing sulfur in soil and sediment with handheld XRF

    Background Sulfur creates more than nasty odors. Exposure to low levels (0-10ppm) of hydrogen sulfide (H2S) causes irritation of eyes, nose, and throat; higher levels can cause headaches, dizziness, nausea and vomiting, coughing, and breathing difficulty. H2S and numerous other odor-causing compounds are generated as a result of organic material decomposition. In the case of the Muddy River in ...

  • Elk Point Country Club CC HOA, Nevada - Case Study

    In early March, 2009 after an evaluation period, AdEdge Water Technologies, LLC. was selected among other alternatives and contracted by Elk Point Country Club Community (EPCCHOA) to provide a packaged treatment system for uranium removal that complied with the Nevada Department of Environmental Protection (NDEP) regulations. The EPCCHOA is located on the South East side of Lake Tahoe at Elk ...

  • Arrowbear Park, California - Case Study

    In July 2010, AdEdge Water Technologies, LLC was contacted by Engineering Resources to design, manufacture and install a uranium water treatment system for the community of Arrowbear Park County Water District in the San Bernardino National Forest. The community water system has a raw water uranium concentration of 118 parts per billion well above the EPA maximum contaminant level of 30 parts per ...

  • Prospects for nuclear energy in Eastern Europe and the Caucasus

    This paper presents an analysis of the prospects for nuclear energy development in the Eastern European countries of Belarus and Ukraine and in the Caucasian countries of Armenia, Azerbaijan and Georgia. The main focus is on Ukraine, but some reference is made to the prospects for energy development in other countries of Eastern Europe and the Caucasus. The contribution of nuclear energy to ...

  • Researchers discover high uranium levels in south India groundwater

    The uranium isotopes during their course of their disintegration decay into other radioactive elements and eventually decay into stable lead isotopes. The cause of environmental concern is the emanation of beta and gamma radiation during disintegration. The present study tends to estimate uranium in groundwater trapped in granite and gneiss rocks. Besides, the study aims at estimating the ...

  • Barona Resort & Casino, California - Case Study

    In mid 2007, AdEdge was contacted by Pacific Advance Civil Engineering group (PACE) to assist a Native American Tribe in Southern California near San Diego to provide a packaged treatment system for uranium removal.

  • Uranium mining and milling: material security and risk assessment

    At present, physical protection for the front end of the nuclear fuel cycle is typically at a significantly lower level than at any other part of the nuclear fuel cycle. However, in view of past experiences it is feasible to take into consideration some generic threat scenarios, potentially resulting in loss of control over the nuclear material, respectively its by-products, such as: illegal ...

  • Determination of uranium concentration in surface soil samples of Iran

    The use of uranium-tipped antitank shells during the Iraq war (2003) caused serious concerns in Iran and the international media over possible contamination of the Iranian environment and consequent long-term health effects. After a shell explosion, uranium is discharged by fire into the air in the form of oxidised particles, which can be dispersed over a radius of several kilometres. Gamma ray ...
