  • Simultaneous determination of PM fractions, particle number and particle size distribution in high time resolution applying one and the same optical measurement technique

    Abstract The Fidas fine dust monitoring systems comprise an optical aerosol spectrometer, which is characterized by very good instrument characteristics, and utilize a sophisticated approach to convert the measured information on particle number and particle size into mass concentrations. As monitoring of PM requires reliable and quality-controlled performance of the measuring systems, ...

  • New laser-based dust emission monitoring system

    Abstract A new generation of continuous particulate matter concentration monitoring instruments is presented, covering a measuring range of 0 to 1000 mg/m3. The laser-based scattered light instrument gives an improved stability as well as excellent resolution in the low range. This enables high concentration measurement as well as especially low emission monitoring down to 0.01 mg/m3 with a ...

  • Reflectance spectroscopy as a tool for settled dust monitoring in office environment

    The aim of this study was to develop a technique based on reflectance spectroscopy that is capable of evaluating small amounts of sediment dust. Laboratory simulations and two field experiments conducted in the same office environment were carried out to generate particulate dust samples based on multivariate data analyses. Spectral measurements were taken using either a laboratory Quantum 1200 ...

  • Asbestos monitoring – what monitor should I be using?

    Asbestos is the name given to a group of minerals that occur naturally as masses of strong, flexible fibres that can be separated into thin threads and woven. These fibres are not affected by heat and do not conduct electricity. Asbestos is chemically, relatively stable. For these reasons, asbestos has been widely used in many industries.  These four types are classified as follows:  ...

  • Monitoring Environmental Quality

    ' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...

  • ‘New for old’ dust analyser deal brings 96.66% data capture rates to NE Lincs

    With the UK’s largest port and the industrial town of Grimsby in its jurisdiction, air quality monitoring is a primary concern for North East Lincolnshire Borough Council. When DEFRA reported that the TEOM dust analysers the council relied on weren’t up to standard, rapid action was required and Enviro Technology (ET) stepped in with its BAM 1020s. North East Lincolnshire is the ...

  • GM-Delphi: Whirl / Wet Combines High Efficiency Wet Dust Collection with Low Maintenance and Operating Costs

    Tri-Mer® dust collection technology has once again been selected by GM-Delphi. Four units were selected as replacements for dry collectors. Each unit serves four grinding (or shot blasting) stations. Capacities range from 425 to 52,500 cubic ft./minute. The units will accommodate very heavy loadings under continuous use, and allow regular maintenance without interrupting production. Equally ...

  • Workplace Monitoring: Who, What, When, Why, How?

    In my previous articles in this series for SHP readers, I have focussed on the need for current attitudes to general health and safety processes to change and emphasised the importance of regular monitoring. The best way to combat those ‘hidden killers’ and protect our workforces is to increase awareness of the benefits of regular monitoring and detection.  Employees then need to ...

  • Stacking up: flare Monitoring from LumaSense

    Lenny Shaver, LumaSense Technologies’ director of product management, explains the company’s IR and pyrometer technologies FLARING systems are common in many industries to burn gases before they enter the atmosphere. The safe operation of a flaring system requires the continuous monitoring of pilot flames and flared gases to ensure that vented gases are ignited. As ...

  • Portland Cement Manufacturer Upgrades Technology,Improves Operation and Reduces Costs

    One of the largest Cement factories in America was interested in reducing frequent visual emissions inspections mandated by new Portland Cement (MACT) rules in effect since June 2002. A second issue was the need to measure solids flow in the finish mill operation to determine the rejects flow rate. During a recent upgrade to the finish mill circuit, the rejects flow, which is traditionally ...

  • So Your Greenhouse Gas (GHG) Monitoring Plan is Complete... Now What?!?

    U.S. EPA's Greenhouse Gas Mandatory Reporting Rule (GHG MRR) codified at 40 CFR Part 98 required that facilities subject to the rule have a complete written GHG Monitoring Plan by April 1, 2010. At a minimum, the GHG Monitoring Plan must identify (1) methods used to collect GHG emissions information and supporting data, (2) personnel responsible for collecting the data, and (3) quality assurance, ...

  • NOx in Non-Utility Industries - Part II - Control options and monitoring methodology

     This the second in a two-part series. Part I, which appeared in our June 2001 issue focuses on air emission origins of nitrogen oxides (NOx) in non-utility industries. Choice of the NOx control technology is dependent on many factors, including regulatory requirements, technical feasibility, cost and public perception. Figure 1, compiled based on publications [1-5], presents a summary of ...

  • Measurement of Trace metals in Ambient air case study

    Trace metals are found at low concentration in the ambient environment and are associated with adverse health effects. The gold standard metal measurement is Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES); however, sample preparation is laborious and expensive. The Xact 625 metals monitor uses non-destructive X-ray fluorescence technology. A built-in sample collection system ...

  • Maintenance tips for cooling towers - White Paper

    Cooling towers are prone to the typical causes of rotating machine failure such as misalignment, but also face a range of specific environmental challenges, including high or gusting wind speeds, dust, sand and, in coastal locations, high concentrations of salt. In the 1990s, for example, vibration and accelerated wear caused a fan blade to shear off a cooling tower in Pennsylvania, ...
