  • GPR goes underground: Pipe Penetrating Radar

    Abstract: Pipe Penetrating Radar (PPR) is the underground in-pipe application of ground penetrating radar (GPR) either robotically or by manned entry to reveal wall thickness, delamination, voids, and other conditions that enable more precise determination of pipeline integrity and verifications for trenchless technology rehabilitation. PPR, when applied to pipe-bursting applications, can ...

  • Affinity–based biosensors for heavy metal detection

    In recent years, there has been a pressing need for fast and reliable methods for environmental monitoring. Among the various pollutants, the heavy metals are some of the most harmful because these substances are non–biodegradable and retained by the ecological system. Conventional analytical techniques for heavy metals imply high cost, trained personnel and the repute that they are mostly ...

  • Understanding Challenging Applications for Improved Metal Detection

    In the food industry, certain products can act like metal contaminants, a phenomenon known as ‘product effect.’ This is where the type of product being inspected can hinder the ability of inspection technology to correctly identify metal. At best this can lead to unacceptable false reject levels, at worst it can result in metal contaminated product leaving the production facility. ...

    The REDWAVE Metal Days, at BT-Wolfgang Binder in Gleisdorf, pro­vided the context for international experts from various sectors of the metal and aluminium recycling in­dustry to exchange information on markets, technologies and practical experience. In addition, the new REDWAVE XRF-M sorting system, for recycling in the metals sector, was presented to the participants. ...

  • Fixed Versus Portable Gas Detection – Which Is Better?

    Did you know that workers are needlessly injured every year as a result of leaking toxic or combustible substances? Such incidents are known to involve a wide range of hazardous gases (including ammonia, carbon monoxide, chlorine, hydrogen sulfide, hydrocarbon vapors and so on). The sad reality is that most of these accidents are avoidable if only the workplace is adequately monitored. This leads ...

  • Listening In: Smartball Detects Ancient Buried Sounds

    For this leak detection survey, Pure’s innovative free-swimming acoustic tool gathered critical information about the aging pipeline assets of this historic Arabian city. This large public utility supplies bulk water to this bustling, historic resort city located in the Arabian Penninsula region. The city’s infrastructure – above ground and below – ...

  • Developing Technologies to Detect Hydrogen Sulfide (H2S) Gas

    Abstract Hydrogen sulfi de (H2S) gas can cause nausea, headaches, unconsciousness, and death. Industries struggle to detect this deadly substance before it harms workers or communities. Safety system manufacturers have developed detectors that sense the H2S quickly and accurately. This paper illustrates, in general terms, considerations in effective placement of H2S detectors: ...

  • Validation of SPE-TOXcontrol for the determination of metals in drinking water

    Supervisors: Ramón López & Susana González Blanco; CETaqua; Dr. C.A.M. Broers, microLAN B.V. The potential of SPE-TOXcontrol as a new early warning system to detect possible hazards in drinking water was assessed. The work was done in the framework of the WATMATIN project funded by the Spanish Ministry of Science and Innovation…. The evaluation of SPE-TOXcontrol ...

  • Oligonucleotide-based fluorescence system for sensitive and selective detection of Ag(I) ions in aqueous solution

    In this letter, a new homogeneous assay with high sensitivity and selectivity was developed for the detection of silver ions in aqueous media at room temperature by using EvaGreen (EG), polycytosine oligonucleotide C20 and single-walled carbon nanotubes (SWNTs). The fluorescence of EG is weak in the absence or presence of randomly coiled C20. After C20 interacted specifically with Ag+ ions ...

  • Metals Determination in Biodiesel (B100) by ICP-OES with Microwave Assisted Acid Digestion

    Elemental composition of biodiesel is required for product quality control, auto-engine life, emissions control, and researching appropriate additives. We studied the use of microwave assisted acid digestion reaction system to prepare neat biodiesel (B100) samples in an aqueous medium for ICP-OES analyses. Biodiesel produced by a transesterification reaction was subjected to the test method for ...

  • The use of some industrial by products for adsorptive removal of heavy metals from wastewater

    Most available technologies applied in the removal of metal contaminants in aqueous systems use the well established processes of adsorption. Adsorbents currently in use are either too expensive or not readily available for wastewater treatment. There is a need to develop new adsorbents which are readily available at low cost to remove metal contaminants in aqueous system. In this work, Okra ...


  • Seasonal Fluctuation in Heavy Metal Pollution in Iran`s Siahroud River

    Abstract BackgroundThe management of its available water resources has become a key issue for Iran. During the last few decades, the water quality of Siahroud River in the coastal plain of the Caspian Sea in Gilan Province in Northern Iran has significantlydegraded. The scarcity of water has been compounded by rapid population growth and increasing pollution from ...

  • What’s New? Maximizing The Life Of Aging Metallic Pipelines With Modern In-Line Technology

    Maximizing the life of aging pipelines has long been a challenge in North America.

  • PureAire Oxygen Analyzer for 3D Printers: How Argon is used and Why O2 Detection is Required

    Thanks to new technologies, the 3D printers that have been used to create plastic three-dimensional objects can now print metal. Titanium 3D printing is possible thanks to a technique called DMLS, or Direct Metal Laser Sintering. While the potential to use titanium 3D printing is groundbreaking for many industries, the new advances could pose a health hazard if volatile gases used in the printing ...

  • Making Every Drop Count: Unitywater uses leak detection as a foundation for condition assessment

    It stands to reason why many utilities respond to leaks only after they receive a call about water gushing from a street or a complaint from a customer about a damp basement, or other signs of visible leakage. Human nature reflects the adage that is often easier to respond to an ...

  • Probabilistic approaches to accounting for data variability in the practical application of bioavailability in predicting aquatic risks from metals

    The Biotic Ligand Model (BLM) theoretically enables the derivation of Environmental Quality Standards that are based on true bioavailable fractions of metals. Several physico‐chemical variables (especially pH, major cations, DOC and dissolved metal concentrations) must, however, be assigned to run the BLM, but they are highly variable in time and space in natural systems. This paper describes ...
