  • Determination of Flow Rates in part-filled Applications using the Radar Method

    Introduction The radar measurement method plays an increasingly important role in the water and wastewater field. This is particularly reflected by the "Metering outside of the medium" trend. Flow measurement using radar which enables contactless measurements thus becomes a major focal point. It features a wide range of applications and hence is useful as permanent measurement system for ...

  • Solar radiation (PAR, UV-A, UV-B) penetration in a shallow maturation pond operating in a tropical climate

    Solar radiation is considered the primary route for disinfection of pathogenic bacteria in maturation ponds. There is scarce information on depth profiling and attenuation of photosynthetically active radiation (PAR), UV-A and UV-B in shallow maturation ponds operating in tropical climates. Measurements of solar irradiance of the three wavelength ranges, together with turbidity, have been ...

  • What is a Spectrometer?

    The characteristics of a white LED light differs greatly, when compared to a yellow CFL. Without any special tools, one can see that the LED emits a clear white color, while the CFL generates yellow light. Going one step further, using a spectrometer, one will be able to “dissect” the light sources and see that they are composed of other colors in the visible light spectrum, such as ...

  • Isotherms, thermodynamic and mechanism studies of removal of low concentration uranium (VI) by Aspergillus niger

    In order to develop an effective and economical method for removing low concentration radioactive wastewater of uranium, the biomass of ‘CMCC(F)-98003’ Aspergillus niger was investigated in a batch system. The maximum uranium adsorption capacity of 12.5 mg g−1 was obtained at the initial uranium concentration of 0.75 mg L−1. The biosorption data on a biomass ...

  • The Key To Controlling Airborne Contamination In Food Processing

    In the food and beverage industry, contamination is always a high priority concern. Small mistakes in handling, preparation, and even in the cleaning of the environment where food comes into contact with surfaces can cause disastrous results that can potentially affect hundreds of thousands of people. Often overlooked is the threat from another source of food contact: air. ...

  • Natural radionuclides in waste water discharged from coal-fired power plants in Serbia

    Investigation of the natural radioactivity levels in water around power plants, as well as in plants, coal, ash, slag and soil, and to assess the associated radiation hazard is becoming an emerging and interesting topic. This paper is focused on the results of the radioactivity analysis in waste water samples from five coal-fired power plants in Serbia (Nikola Tesla A, Nikola Tesla B, ...

  • A High-Performance Base-Metal Approach for the Oxidative Esterification of 5-Hydroxymethylfurfural

    Exploring high-performance base-metal approaches for the sustainable production of chemicals from biomass is presently attracting immense interest and is truly important to promote their industrialized application. Herein, CoOx-N/C and α-MnO2 were combined as a base-metal catalyst that can achieve high yields of furan-2,5-dimethylcarboxylate (FDMC, 95.6 %) for ...

  • How to treat radioactive NORM sludge with VacuDry

    NORM doesn’t sound like a big thing. But Naturally Occurring Radioactive Material might let the alarm bells ring. Everyone has heard of “radioactive material” and that sounds dangerous. However, most of this material is trapped deep in the ground beneath our feet. From there it reaches the surface, for example via the water cycle. Another possible pathway for NORM to reach the ...

  • Measurement Science and Technology Paper - Potential for improved radiation thermometry measurement uncertainty through implementing a primary scale in an industrial laboratory

    A primary temperature scale requires realising a unit in terms of its definition. For high temperature radiation thermometry in terms of the International Temperature Scale of 1990 this means extrapolating from the signal measured at the freezing temperature of gold, silver or copper using Planck's radiation law. The difficulty in doing this means that primary scales above 1000 °C require ...

  • Spatial differences in trace element bioaccumulation in turtles exposed to a partially remediated coal fly‐ash spill

    Large‐scale releases of environmental contaminants from industrial facilities can cause considerable damage to surrounding ecosystems and require remediation. The expense and/or undesirable environmental side effects of physical removal may constrain remediation efforts. In 2008, approximately 4.1 million cubic meters of fly‐ash were released into the Emory River at a coal burning power plant ...

  • Sizing and Selecting the Proper Metering Pump: Part 1 of 2

    A typical agriculture or process application can consume large amounts of chemicals during daily operations. While the volumes may be large, though, they must also be very precise, with exact amounts delivered according to strict injection schedules. The pressures—from very high to very low—that the chemicals are injected at must also be governed precisely. This demand for ...
