  • How to treat radioactive NORM sludge with VacuDry

    NORM doesn’t sound like a big thing. But Naturally Occurring Radioactive Material might let the alarm bells ring. Everyone has heard of “radioactive material” and that sounds dangerous. However, most of this material is trapped deep in the ground beneath our feet. From there it reaches the surface, for example via the water cycle. Another possible pathway for NORM to reach the ...

  • New LWT system improves safety for workers dredging radioactive materials

    Problem: Cleanup crews wanted to dredge radioactive sludge from hazardous waste pits without releasing contaminants to the environment. Solution: A remote-control system encloses the radioactive material during dredging and keeps workers at a safe distance. The Weldon Springs, Mo. Superfund site and remedial action project has four pits containing low-level radioactive raffinate debris and ...

  • Waste Management Overview

    Introduction Our Nation has entered an era in which, as a result of changing world conditions, nuclear weapons production is receiving less attention while the public is expressing increasing concern about protecting human health and preserving the quality of our environment. In response to this national concern, the Department of Energy (DOE) has made waste cleanup and environmental restoration ...

  • The shredding of hospital and medical waste

    Waste produced in hospitals is a type of waste considered special or dangerous, as the material is composed of different elements:  biological and anatomical components, single use items deriving from surgical treatment, material used by healthcare personnel such as shirts, caps and masks, bandages, medicines used by patients, single-use glass and plastic containers used for extracting and ...

  • All Waste is not created equal

    If you live in a house, apartment or similar abode, you produce waste. Right? You probably can't go a week without producing waste. All kinds of waste. Call it trash if you want. It's still waste. And if you don't live where recycling is mandatory or there is no outlet for your voluntary environmental tendencies, everything goes into the trash - bottles, cans, cardboard, plastics, bottle caps, ...


  • Nuclear Waste: Greatest environmental challenge facing society

    Dr Tim Johnson discusses how we can tackle the nuclear waste epidemic. A world full of waste They say you can tell a lot about a society by what it throws away. Like me, I’m sure you can recall the excitement of archaeologists on numerous TV documentaries, sifting through the remains of a rubbish dump or ‘midden’ on the edge of some ...

  • NORMs contamination treatment using Ivey-sol technology

    NORMs (naturally occurring radioactive materials) are found almost everywhere, and many natural materials, such as the earth’s crust, contain such radioactive materials. So what happens when oil and gas activities such as petroleum refining and natural gas extraction, disturb such radioactive material? They can alter the natural background radiation — the radiation that we are naturally exposed ...

  • Nuclear Plant in southeastern United States case study

    Turning Liquid Waste into Solid Money Savings using QUIK-SOLID© Project Background: A nuclear plant located in southeastern United States had to dispose of approximately 7,000 gallons (26,488 L) of liquid sludge that resulted from aggressive preventive maintenance activities. The plant stored the watery sludge in B-25 boxes (90 ft each). The slightly ...

  • FRACKING: Freeing Energy Resources versus Polluting the Earth and Public Health with Radiation and Toxic Chemicals?

    Fracking demands the use of millions of gallons of water, precious drinking water, and sand infused with up to 1,000 different toxic chemicals to fracture the shale rock and release the trapped gas or oil. The wastewater, brine, and sludge are then returned to the surface and in need of disposal. Unfortunately there is not yet a clear and safe method of disposal or storage. Among these chemicals ...

  • Remote control dredge prevents contamination at Fernald, Ohio nuclear remediation site

    When the operations manager at the Fernald, Ohio Super Fund Site Remedial Action Project needed a dredge to remediate sludge from one of four on-site waste (raffinate) pits, they required more than the usual dredging standards. The dredging operation was complicated with the possibility of unknown radon emissions, chemical contamination, and radiation that could be unleashed as material was ...

  • Dredging at weldon spring super fund project Morrison Knudsen - St. Charles, Missouri, USA

    Remote controlled Dredging proved to be the best method of removing radioactive sludge from settling ponds of a former uranium processing plant near St. Charles, Missouri. Dredging keeps the material wet and out of contact with the atmosphere throughout the removal and treatment process, eliminating the danger of contaminates becoming airborne. The Weldon Spring Site Remedial Action Project ...

  • Separation

    Introduction: Ex situ separation can be performed by many processes. Gravity separation and sieving/physical separation are two well-developed processes that have long been primary methods for treating municipal wastewaters. Magnetic separation, on the other hand, is a much newer separation process that is still being tested. Gravity Separation Gravity ...

  • Case study - Westbay System Data improved understanding of groundwater conditions in geologic repository

    Multilevel well system delivered accurate measurements of hydraulic properties CHALLENGE One of the major challenges facing  ANDRA during the initial stages of  construction was to monitor the effects of  construction on the geological formations  overlying the argillite. SOLUTION To monitor changes in ...


  • Lower costs, fewer delays - a highway expansion project applies XRF technology to obtain cost-effective remediation.

    X-ray fluorescence (XRF) spectrometry is a non-destructive, analytical method used primarily to detect the metal composition in soil/solids samples. Portable XRF instruments can provide rapid, accurate analysis of heavy metal levels in soil on new construction or redevelopment sites. In response to the growing need for field analysis of metals, many of these units have been adapted for use in the ...

  • What is Wastewater?

    What is wastewater? Wastewater, the waste discharge that first comes to mind in any discussion of stream pollution, is the discharge of domestic wastewater, which contains a large amount of organic waste. Industry also contribute substantial amounts of organic waste, some of which comes from vegetable and fruit packing; dairy processing; meat packing; tanning; processing of poultry, ...

  • Incineration

    Introduction: High temperatures, 870 to 1,200 °C (1,400 to 2,200 °F), are used to volatilize and combust (in the presence of oxygen) halogenated and other refractory organics in hazardous wastes. Often auxiliary fuels are employed to initiate and sustain combustion. The destruction and removal efficiency (DRE) for properly operated incinerators exceeds the 99.99% requirement for hazardous waste ...

  • Wet electrostatic precipitators: A preferred technology for emission control

    The basic science behind electrostatic precipitators is as familiar and as simple as static cling. But today, this elemental force has been harnessed to a technology that is helping to remove millions of tons of toxic chemicals from our atmosphere; saving billions of dollars annually in pollution-related physical damage; and averting costly impacts on health and mortality rates for millions of ...

  • Managing Environment, Health and Safety Risks at the National Museums of Kenya for Sustainability

    AbstractUrban environmental policy cannot escape the dictates of global environmental requirements as stipulated by the principles of Stockholm Conference, Rio-Summit, and the Johannesburg Summit that includes multilateral environmental agreements. The National Museum of Kenya (NMK) is a public, educational, scientific and heritage management institution established in 1909. It has undergone ...


  • Properties and Behavior of Inorganics in Contaminated Soil

    Often, specific technologies may be ruled out, or the list of potential technologies may be immediately narrowed, on the basis of the presence or absence of one or more of the chemical groups. The relative amounts of each may tend to favor certain technologies. Metals may be found in the elemental form, but more often they are found as salts mixed in the soil. At the present time, treatment ...
