  • Mining Emissions Effectively Monitored with Micro Pulse LiDAR Technology

    Mining operations include blasting, excavating, scraping, and sifting large amounts of dirt. These activities create dust and other emissions that are transported by air currents to surrounding areas. It is easy to say that dangerous particulate matter (PM) generated by mining should be monitored and kept to a minimum; however, it is very challenging to measure the levels of contaminants in the ...

  • Micro Pulse LiDAR: A Critical Tool for Emissions Source Detection

  • Safety and Noise Tips of Industrial Fans

    When choose industrial fans, the user maybe confused, and do not know which kind is better. While a good industrial fan is not only meeting performance requirements,but also involving safety and noise. Five safety standards for large industrial fans as follow: 1. Check whether the motor head and the whole machine will shake when rotating in low and medium speed gears, especially in high speed ...

  • Alternative Fuels - A Look At the Current Environment

    Overview Vehicles powered by gasoline and diesel account for emissions of dangerous air pollutants and contribute to the presence of greenhouse gases. Consumers, businesses, and public entities looking for environmentally friendly alternatives to gasoline and diesel-powered cars and trucks have viable choices beyond the well-known battery electric and plug-in hybrid electric ...

  • Micro Pulse Lidar: Perfect Tool for Atmospheric Research

    Micro pulse style lidars are active remote sensing tools proven to be highly useful in atmospheric research. This style of backscatter lidar has been around for decades; however, incremental improvements in photon counting, sensitivity, polarization, optical filters, coatings, and precision machining of each element support increasingly accurate analysis. Each iteration of the ...

  • Top 5 Differences between Micro Pulse LiDAR and Ceilometer Technology

    If you are evaluating backscatter LiDAR sensors for measuring aerosols, cloud vertical structure, and planetary boundary layer (PBL) heights, what factors should you consider in your comparison? It really comes down to a choice between the traditional analog technology used in ceilometers and the more recent advanced technology found in Micro Pulse LiDAR (MPL) sensors. ...

  • Multiple Instruments Work Together for a Better View of Air Quality

    Accurately identifying and quantifying particulate matter (PM) in the atmosphere is key to determining air quality. Researchers are particularly interested in PM that have a diameter of less than 2.5 micrometers because they are believed to contribute to heart and lung disease in humans and animals. These tiny particles are invisible to the naked eye and originate from power plants, fires, and ...

  • Phoenix Technologies - Green Machine solutions case study

    Problem Phoenix Technologies of  Bowling Green, OH  is a leading PET plastic recycler who was spending approximately $120,000 annually on replacement air filters. The Solution Phoenix sent us filters for testing and were satisfied that the Green Machine will be a perfect solution to dramatically lowering replacement filter ...

  • Puraflex Design and Installation Instructions

    In order to produce an effective barrier to contamination, any membrane must be installed properly by personnel familiar with the material.  Any defects in jointing or preparation of the sub-base could damage the integrity of the lining system and ultimately lead to barrier failure. ITP LTD's Design and Installation Guide describes the quality control measures, earthworks/ground preparation, ...

  • Case Study: Major Southern California Studios

    Most studios require - and Ellis is pleased to provide - emergency response services, from mold testing, to indoor air, to asbestos removal. Most recently, Ellis managed a $40,000 cleanup of the air supply system of a huge filming stage, following a fire and resultant smoke damage. Other services provided since 1995 include numerous asbestos and lead surveys, abatement projects, soils testing, ...

  • Preparing Test Specimens Using Undercompaction

    A specimen preparation procedure is presented that offers an improved method of preparing reconstituted sand specimens for cyclic triaxial testing. The method leads to more consistent and repeatable test results. This procedure (1) minimizes particle segregation, (2) can be used for compacting most types of sands having a wide range in relative densities, and (3) permits determination of the ...

  • Chemical oxidization of some AFFFs leads to the formation of 6:2FTS and 8:2FTS

    The present study tested some aqueous film‐forming foam (AFFF) products for the presence of or the potential to form 1H,1H,2H,2H‐perfluorooctanesulfonic acid (6:2FTS) and 1H,1H,2H,2H‐perfluorodecane sulfonic acid (8:2FTS). The results demonstrated the appearance of significant levels of 6:2FTS and 8:2FTS after the oxidization of those AFFFs. The authors concluded that fluorotelomer skeletons ...

  • On the Importance of Rate of Strain in the Consolidation Test

    In many consolidation tests the imposed rate of strain is several orders of magnitude faster than field rates even though it is well known that some of the parameters derived from laboratory tests are strain rate dependent. For this reason it is essential that the standard test procedure provides adequate guidance on the acceptable rate of strain for various classes of natural soils. This paper ...

  • Pedigree and specialisation - Rotork`s strengths in the nuclear power generation industry

    In common with other power generation technologies, nuclear energy relies heavily on electric valve actuators for safe and efficient plant operation. In particular, electric valve actuators are used for crucial safety-related duties, both inside and outside the nuclear containment area or nuclear island. In both cases these duties demand actuators that are built to strict material specifications ...

  • Saltwater flotation for more efficient matrix separation of wetland macroinvertebrates does not affect total mercury or methylmercury concentrations

    We compared benthic wetland invertebrate matrix separation techniques (handpicking vs. saltwater flotation) to test for effects on invertebrate mercury concentrations. Neither total mercury nor methylmercury concentrations differed significantly between techniques across eight taxa. Matrix separation by the flotation technique took significantly less time and resulted in significantly greater ...

  • WQP magazine`s featured article written by company president

    The interest in reducing environmental lead exposure in evident with the recent revision by the U.S. Environmental Protection Agency (EPA) for the nation's Air Quality Standards, which were lowered from 1.5 to 0.15 ug of lead per cubiv meter of air. "With these stronger standards, a new generation of Americans is protected from harmful lead emissions, especially children," said EPA Administration ...

  • The effect of water hammer on a confined air pocket towards flow energy storage system

    This research studies the behavior of a fully confined air pocket under the effect of water pulses induced by a water hammer phenomenon using several experimental tests in a pressurized transient condition. A compressed air vessel (CAV) has been tested under transient conditions to show its ability to absorb the pressure surges and to demonstrate the energy storage capability of the air ...
