  • Antifouling System Reduces Algal and Biological Growth on the In-Situ TROLL 9500 Water Quality Instrument

    Abstract New regulations regarding clean water have increased the need for long-term environmental monitoring. As water quality sensor technology improves and becomes more stable, the limiting factor in these projects becomes biological and non-biological fouling of instrumentation. Biofouling of environmental equipment increases site visits and maintenance, which elevate monitoring costs. ...

  • CO2 Gas Hazards in the Brewing Industry

    The hazards associated with CO2 in the brewing industry are well known, yet people still die needlessly every year in tragic and completely avoidable accidents in breweries. Just last year in Germany, which has a good safety record, two workers died in separate incidents at the same brewery. In the first incident, the owner was found dead with his head and torso in a beer mixing tank. It is ...

  • Noise level monitoring system flashes alerts in real time

    Exposure to harmful noise levels at work and noise-induced hearing loss can be prevented if the right processes and noise level monitoring system is available. Around the world, millions of workers are affected by excessive noise levels in the workplace.  A large proportion are exposed to noise loud enough, in the region of 80dB(A) – 85dB(A), that they have to raise their voices to be ...

  • Smart LDAR — more cost-effective?

    On December 19, 2008, EPA issued a final rule establishing a voluntary Alternative Work Practice (AWP) to detect leaks of volatile organic compounds (VOC) and hazardous air pollutants (HAP) from process equipment (FR Vol. 73, Number 246), thereby providing the regulated community additional flexibility in complying with leak detection and repair (LDAR) requirements. The AWP allows owners or ...

    An engineer repairs buried cables; a plant manager enters a small plant room; a contractor inspects the lining of a sewage pipe.  All these personnel face a common danger, despite working in widely different industries.  Gas-related injury poses a serious threat in any confined space where the free movement of air is limited.  ...

  • Gas Safety in the Laboratory

    Modern laboratories use a number of gases as part of their daily operations. This blog details two of the most common methods of laboratory gas supply, and their associated safety risks and benefits. A number of gases are used in laboratories to support various applications such as Chromatography (GC and LC-MS) Spectroscopy, ELSD and Sample Preparation, to name just a few. Helium, hydrogen and ...

  • Controlling Fugitive Emissions, Part 2: Permanent Total Enclosure

    Fugitive emissions are the uncontrolled release of gases into the atmosphere. This is something that occurs regularly; in fact, it often happens when we fill our cars' gas tanks. The air being displaced inside the gas tank when it is being filled causes gasoline vapor emissions (hydrocarbons) to exit into the atmosphere in an ...

  • Miller Argent case study

    On the hills above Merthyr Tydfil, Miller Argent is undertaking a highly ambitious land reclamation scheme that is also involving the extraction of coal by opencast methods. Known as the 'Ffos-y-fran Land Reclamation Scheme', this is the third and final phase of the East Merthyr Reclamation Scheme which is expected to run for another 17 years.

  • Erosion Control Specialist Uses Troll 9000 to Demonstrate How Construction Site Runoff Impacts Water Quality

    Study 1 - 2003: Monitoring slltatlon from construction runoff In 2003, water quality testing was performed at a construction site in order to document the direct impact to a nearby creek. The purpose of this test was to show that erosion and sediment controls at the construction site were inadequate to handle the associated volume of runoff. Large silt loads downstream were observed during ...
