  • 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 ...

  • Controlling Dust and Bioaerosols at a Biosolids Composting Faclity

    Studies at enclosed Longmont, Colorado project evaluate exposure level of employees. Operational changes reduce dust, endotoxin and A. Fumigatus by 90 percent. WHEN dealing with public health issues and composting, attention has been predominantly focused on potential exposure from the release of Aspergillus fumigatus (A. fumigatus) from composting facilities. Numerous studies were conducted to ...


  • Exposure to dust, endotoxin and airborne microorganisms in wastewater sludge thermal drying units

    The objective of this study was to assess workers' exposure to bioaerosols in sludge drying units. Simultaneous collection of inhalable dust and airborne biological agents was carried out using rotating cup samplers (CIP 10, Arelco). Sixteen stationary and 30 personal measurements were performed in three drying plants, during summer and winter. Microbial content of air was characterized by high ...

  • 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 ...

  • Air Separation Plants and the Use of Oxygen Monitors

    Air separation plants are critical for many different industries, from clean energy to manufacturing. Nowadays, cryogenic is the most common type of distillation used to separate air into its component gases - nitrogen, oxygen, and inert gases including helium and argon. If your industry relies on air separation for product development or manufacturing, then knowing how the process works is ...

  • Designing and Implementing Perimeter Air Monitoring Programs

    Perimeter or fenceline ambient air quality and meteorological monitoring programs have become increasingly valuable at hazardous waste, landfill, dredging, ports, and MGP remediation sites. Air quality monitoring programs protect public health and reduce owner liability ...

  • 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 ...


  • Work Safely in Dusty Environments

    Dust is a term used to describe all airborne particles – these can be wood, stone, flour, concrete, grain, mould or asbestos particles as well as fumes and chemicals. Many activities create dust. Larger dust particles get lodged in the nose and throat while the smaller more dangerous particles get lodged deep in the lungs – these dust particles are the ones that can cause fatal ...

  • 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 ...

  • 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, ...
