  • Impact of hydraulic loading rate and media type on removal of bulk organic matter and nitrogen from primary effluent in a laboratory-scale soil aquifer treatment system

    The effect of hydraulic loading rate (HLR) and media type on the removal of bulk organic matter and nitrogen from primary effluent during soil aquifer treatment was investigated by conducting laboratory-scale soil column studies. Two soil columns packed with silica sand were operated at HLRs of 0.625 and 1.25 m/d, while a third column was packed with dune filtering material and operated at HLR ...

  • Characterisation of potassium bromide loaded with dysprosium fluoride nanocrystals for neutron detection

    We explore a novel concept of passive optically–enabled detection of thermal neutrons that exploits transmutation of 164Dy into 165Ho. The concept relies on significant differences in optical properties of Dy and Ho and on our ability to find the most sensitive optical method of differentiating between Dy and Ho. While the concept ...

  • Wood waste becomes bigger part of picture for Colorado materials recycler

    Since it entered the materials recycling arena in 1979, Oxford Recycling has successfully focused its efforts on bringing new life to concrete, asphalt and scrap tires. In 1999, the Englewood, Colorado-based company began taking in wood waste as part of its overall operation, and chose to subcontract the grinding part of that business. A recent significant upturn in volumes prompted Oxford’s ...

  • Development of Industry Consensus Standards for Recycled-Plastic Lumber

    Just a decade ago, recycled-plastic lumber (RPL) was used mainly for park benches, picnic tables, and other non-critical load bearing applications. While produced in common dimensional lumber sizes, RPL materials have some important mechanical property differences compared to wood. The thermodynamics of processing RPL materials produce products that are non-homogeneous in their cross-section. ...


  • Investigation of a Plate Index Test for Railroad Ballast

    A need exists to determine the physical state of ballast in railroad track. The use of a small surface bearing plate was investigated for this purpose. The measurement problem is particularly difficult because ballast is a coarse, angular material with particle sizes up to 50 to 75 mm (2 to 3 in.) in diameter, for which the bulk properties to be assessed vary over distances as short as 300 mm (1 ...

  • Weigh batching: the benefits of an automated system

    In many plants that batch-blend bulk products, weigh batching is a manual, time-consuming operation in which ingredients are weighed individually before being charged to a blender or other process vessel. A significant number of such plants could benefit from the installation of an automated weigh batching system. For small as well as large operations, an automated weigh batching system can pay ...
