  • The true value of magnetic separators and metal detectors in bulk handling

    Introduction The purpose of a bulk material handling may be to transport material from one of several locations to an ultimate destination or to process material such as ore in concentrating and smelting or handling materials for manufacturing. The handling of dry materials in loose bulk form involved the extensive use of static machinery such as belt conveyors, screw conveyors, and various ...

  • Handling Bulk Foods? Inspecting Them Can Save You Money

    A new white paper from Mettler-Toledo explains how bulk food inspection systems can protect consumers and minimise the risk of expensive product recalls by eliminating physical contaminants. Bulk food product inspection systems are specifically designed to inspect a wide range of loose, bulk foods at various stages of the production process. Despite frequently inspecting loose ...

  • 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 ...

  • No Small Task: Regulating Nanotechnology To Ensure Safety, Maximize Benefits

    Nanotechnology is about engineering at the same size as large molecules like DNA, which is two nanometers wide — a nanometer is a billionth of a meter — or even smaller. Smallness has its virtues. Nanoscale zinc oxide diffracts light better, making a better sunscreen. Similarly, ultrathin nanoscale films are improving the efficiency of cell phone screens and photovoltaics. In the future, moving ...

  • Organic micropollutant removal from groundwater: comparison of pellet softening and nanofiltration

    This study investigated the fate of selected pharmaceuticals and estrogens and the characteristics of bulk organic matter during pellet softening and proposed a possible hybridization with nanofiltration (NF) treatment. A groundwater softening system called pellet softening was used to remove calcium ions from groundwater by crystallizing calcium carbonate on the surface of sand grains that ...

  • In situ microscopy as a tool for the monitoring of filamentous bacteria: a case study in an industrial activated sludge system dominated by M. parvicella

    The present study demonstrates the application of in situ microscopy for monitoring the growth of filamentous bacteria which can induce disturbances in an industrial activated sludge process. An in situ microscope (ISM) is immersed directly into samples of activated sludge with Microthrix parvicella as dominating species. Without needing further preparatory ...

  • A novel acoustic imaging tool for monitoring the state of rapid sand filters

    A new technology based on acoustic waves is developed to monitor the state of sand filters used in drinking water treatment. Changes in the sand filter, due to the removal of suspended particles from the water and their accumulation in the pores, result in an increase of the bulk density and acoustic speed of the granular material. Consequently, the reflected acoustic response changes as the ...

  • Properties and Behavior of Fuels

    Fuel contaminants are generally nonhalogenated. Information presented for nonhalogenated VOCs and nonhalogenated SVOCs may also be appropriate for many of the fuel contaminants presented in this subsection. Contamination by fuel contaminants in the unsaturated zone exists in four phases: vapor in the pore spaces; sorbed to subsurface solids; dissolved in water; or as NAPL. The nature and extent ...

  • Typical process weighing applications

    Process weighing relates to the weighing of a powder material as part of a production process. The technology includes continually monitoring a material in a silo, discharging material by weight or rate, or even weighing products on the move. This article gives an overview of most of the typical process weighing applications that are used in all sorts of industries: level or inventory measuring ...

  • Buried debris case study

    Saufley Field, Escambia County, Florida GeoView was tasked with performing a geophysical investigation at a military base in the southeastern United States. The purpose of the investigation was to locate a reported debris burial pit. The burial pit was reported to be 60 feet (ft) in length and up to 10 ft deep. Historical records indicated that the pit  contained buried drums and ...

  • Application of Mossbauer and positron annihilation spectroscopies for monitoring of WWER RPV steel degradation

    This paper describes the application of Mossbauer Spectroscopy (MS) and Positron Annihilation Spectroscopy (PAS) to evaluate the microstructure parameters of materials. These methods are used to collect additional characteristics for understanding of degradation processes in Reactor Pressure Vessel (RPV) steels. Samples from the Russian 15Kh2MFA and Sv10KhMFT steels, commercially used at WWER-440 ...

  • Magnetic Separation Myths 4 of 10 – Magnets Can’t Attract Stainless Steel or Can They?

    The vast majority of stainless steel used in plants processing foodstuffs, chemicals, plastics and handling bulk materials whether in solid, liquid or powder form, is non-magnetic. Or is it? Traditionally, Magnetic Separators were installed to remove anything that was magnetically susceptible.  Today, this can even include magnetic plastic, used for gloves and even tools.  Magnetically ...


  • LEGAL LOOKOUT: EPA Proposes Amendment to SPCC Plan Requirements

    On Dec. 12, 2005, the EPA proposed to amend Spill Prevention, Control, and Countermeasure (SPCC) plan requirements to reduce the regulatory burden these requirements impose on covered entities. The agency also released a document entitled SPCC Guidance for Regional Inspectors to assist regional inspectors in assessing a facility's implementation of SPCC requirements. As such, the document is an ...

  • Fires at Composting Facilities: Causes and Conditions

    The subject of fires at composting facilities is a bad news/good news situation. The bad news is that fires are more common than we realize. Ask a group of facility operators if they have had to deal with a fire, and the majority will quietly admit they have. The good news is that we don’t realize that fires are fairly common at composting facilities. Most are neither frequent nor destructive ...
