  • Dry cleaner investigation

    A BEACON Passive Soil-Gas (PSG) Survey was performed at a dry cleaner site in the southeastern United States to determine if Tetrachloroethene (PCE) contamination identified beneath the dry cleaner in a prior BEACON PSG Survey was migrating off site and, if so, in which direction it was moving. This survey involved 30 field samples collected in a grid pattern. Analytical results were provided to ...

  • Microwave Drying of Soils

    Drying of soil specimens in microwave ovens can permit rapid determination of moisture content; such determination is very important in field quality control of earthwork construction. A laboratory study was performed to investigate differences between soil moisture contents based on microwave oven drying and moisture contents developed from conventional drying procedures. For nine materials ...

  • Rapid drying of Lucerne Hay by Maceration case study

    Drying is of major importance in haymaking. The dry matter loss associated with drying is about 25% for fine weather conditions and can exceed 40% when rain occurs. This loss can be minimized by using more efficient conditioning techniques that increase the drying rate and thus reduce the time interval between cutting and baling. Studies in Australia and overseas have shown that hay drying rates ...


  • Dry/Wet Scrubbers for Clean Air Compliance

    Air-scrubbing venturis and towers may be the answer to clean air compliance for small- to medium-sized companies. Forthcoming requirements of the Clean Air Act Amendments of 1990 will inventory many more specific chemicals considered hazardous. From acetaldehyde to xylenes, the list regulated under the air taxies program includes 189 hazardous air pollutants (HAPs). That number may ...

  • The Thermal Probe—Measurement of the Thermal Conductivity and Drying Rate of Soil in the Field

    The thermal probe is a metal rod with an internal heating element and temperature sensor. In the field it is pushed into a predrilled hole in otherwise undisturbed soil, and the thermal properties of the soil are estimated from the temperatures recorded at intervals after a constant power is supplied to the heating element. The following are discussed in this paper: the theory behind the methods ...

  • Dry–wet cycles increase pesticide residue release from soil

    Soil drying and rewetting may alter the release and availability of aged pesticide residues in soils. A laboratory experiment was conducted to evaluate the influence of soil drying and wetting on the release of pesticide residues. Soil containing environmentally long‐termaged (9–17 years) 14C‐labeled residues of the herbicides ethidimuron (ETD) and methabenzthiazuron (MBT) and the fungicide ...

  • Residual indicator bacteria in autosampler tubing: a field and laboratory assessment

    Microbial contamination in surface waters has become a worldwide cause for concern. As efforts are made to reduce this contamination, monitoring is integral to documenting and evaluating water quality improvements. Autosamplers are beneficial in such monitoring efforts, as large data sets can be generated with minimized effort. The extent to which autosamplers can be utilized for microbial ...

  • Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory

    ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...

  • Demonstration of DeconGel at Oak Ridge National Laboratory building 2026

    Challenge In 2003 an area behind the hot cells in Building 2026 at the Oak Ridge National Laboratory (ORNL) was flooded with highly contaminated liquids when a liquid low level waste pipe became clogged. The main contaminants of concern are uranium and plutonium. Transferrable contamination levels are in the 1,000,000 disintegrations per minute range. The area is posted as an airborne ...

  • Mathematical modelling of thin layer drying of fresh green pea ( Pisum sativum ) husk

    Thin layer green pea husk (pericarp) drying characteristics were evaluated in a laboratory scale tray dryer. The drying experiments were carried out at 65, 70, 75 and 80 °C. Mathematical models were tested to fit drying data of green pea husk. The drying process of green pea husk occurred mainly during a falling rate period except for a very short accelerating period at the beginning. ...

  • Estimating losses of dry matter from wetted Alfalfa–Orchardgrass mixtures using cell wall components as internal markers

    Methods previously used to measure recoveries of dry matter (DM) from forages following natural or simulated rainfall often have relied on simple gravimetric techniques, which yielded inconclusive estimates of DM recovery. Our objective was to evaluate insoluble cell-wall constituents as internal markers for estimating recoveries of DM from alfalfa (Medicago sativa L.) or alfalfa–orchardgrass ...

  • Comparing the Performance of Recirculating Cyclones Applied to the Dry Scrubbing of Gaseous HCI with Hydrated Lime
