  • 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 ...

  • 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, ...


  • 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 ...

  • 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 ...

  • 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, ...

  • Pyrolysis

    Introduction: Pyrolysis is formally defined as chemical decomposition induced in organic materials by heat in the absence of oxygen. In practice, it is not possible to achieve a completely oxygen-free atmosphere; actual pyrolytic systems are operated with less than stoichiometric quantities of oxygen. Because some oxygen will be present in any pyrolytic system, nominal oxidation will occur. If ...

  • 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 ...

  • A Neural Model for SPM Concentration Prediction in Coal Mines

    ABSTRACT Coal mines are the major sources of suspended particulate matter. To implement any control techniques or to install any control equipment around the coal mines, ambient concentration of suspended particulate matter should be known. In this paper a model is developed to find the concentration of suspended particulate matter at various locations away from the source. The model is ...


  • 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 ...

  • The New Environmental Insurance Products: When Does it Make Sense to Buy Them?

     Part One Introduction Real estate transactions with environmental problems often founder on attempts to shift the liabilities from one party to the other. In transactions with other types of problems, insurance is a popular risk transfer mechanism,  and is regularly used for that purpose, but it is used far less often when there are environmental risks. This so-called ...
