Air Pollution Data Applications on Environmental XPRT

Data analysis and visualization tools for air pollution and meteorological modelling

Air pollution and meteorology are disciplines where 3D visualization is beginning to become commonplace on the evening news. EVS-PRO ,MVS, and EnterVol provide the tools to visualize and animate this data in countless new ways to meet any requirement from television weather reports to scientific analysis.

Low concentrations monitoring of benzene and aromatic hydrocarbons (BTEX) for pollution control and environmental monitoring

With over 15 years of experience in the measurement of volatile organic compounds (VOC), Environment SA announces the VOC72M, a new generation analyzer for the measurement of BTEX compounds by gas chromatography with photo-ionization detector (PID). The VOC72M can handle up to 40 compounds and eight configurations for analysis. This compact and fully automated analyzer with wide voltage range specifications (90-240V) provides equivalent performance to the laboratory chromatographs and is particularly suited to fixe or mobile ambient air quality monitoring laboratories. The VOC72M is fitted with a PID detector new generation, much more sensitive, more stable and whose lamp does not need to be cleaned; the analyzer integrates flow control fittings a 3 levels security system built on and uses only one gas (nitrogen). This robust and low maintenance instrument performs all the functions (sampling, analysis and data management) in a simple and completely autonomous mode. It is a particular

Air pollution control (APC) equipments for fire laboratories

Fire laboratories perform different types of tests and experiments to analyze the characteristics of products and materials , when exposed to fire. Using these data , manufacturers can improve their products, fire resistance, and their longevity. Although the fire is controlled in a laboratory, many toxic substances are formed and these must be removed before the air is released into the environment. EnviBATs technology is extremely effective for this type of application. It eliminates the particles of all sizes, which also has the advantage that it eliminates the burning smell.

Airport Environmental Monitoring

Water pollution from airport run-off is increasingly coming under public and government scrutiny. As environmental regulations tighten, the ability to monitor for aviation fuel contamination from runway run-off has become essential.

Monitoring sites at airports can be extremely challenging often with no power or telephone lines available and with limited access for maintenance. Chelsea’s robust UviLux Hydrocarbon Sensor with its low power consumption and high accuracy is ideally suited for this application. Installed at various locations around the airport, deployed with it’s own integrated anti-biofouling system, utilising the GSM network, the monitoring sites send data to a secure ftp site, where any internet enabled device can access the data. In this way the systems act as any early warning system allowing any hydrocarbon discharge to be detected in real-time.

Optional environmental monitoring features include remote control to allow the user to turn equipment on and off, change the sample rate and detection range. There is also a facility to allow SMS text and email alarm notifications triggered by user-defined set-points together with customised web pages, data displays and automated data downloads via an ftp server.

Airport runoff can contain high concentrations of various pollutants, in particular polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs), the environmental levels of which have to be monitored. An understanding of the magnitude of contamination due to airport runoff water is important for the effective management of airport infrastructure. Chelsea’s robust UviLux Hydrocarbon Sensor with its low power consumption and high accuracy is ideally suited to the airport environment.

Cost effective, real-time pollution monitoring networks

Ambient air pollution is a continuous problematic since many years, and the various organizations in charge of air quality monitoring work constantly on how to improve their structures and gain the most accurate and reliable data possible. Indeed, the changes in mentality and therefore in urbanism development for example, implies an access to the data faster and at multi-location level. Air quality monitoring reference stations used nowadays measure with an extreme accuracy in located areas, but requires a lot of energy, financial investment (to purchase and to maintain) and space. It is not easy then to move them easily, or to multiply them to cover more accurately the area. Cairsens sensors, installed under Cairtub or Cairnet formula perfectly address this problematic: autonomous, very compact, cost effective and ready to install systems, feature a viable alternative or or a complementary measurement methods to the existing reference networks.

Ambient air quality monitoring solutions for fence-line monitoring

The OPSIS open-path monitoring system is an excellent tool for monitoring the air quality, fugitive emissions and gas leaks at industrial sites. By arranging monitoring paths strategically at locations outside the borderline of an industrial area, fugitive emissions and gas leaks will effectively be detected. By combining the measured gas data with meteorological parameters information such as where the pollution sources are located and the strength of the emissions can be calculated, using the EnviMan software.

Odour Monitoring

Measurement of odours from pulp & paper, feedlots and natural sources is challenging and requires careful selection of instrumentation. Ecotech offers a complete monitoring solution designed for this application. Odours are one of the most common sources of air pollution complaints and may be due to a wide variety of sources from rotting vegetation, animal feedlots, pulp and paper manufacturing, sewerage treatment facilities etc. The measurement of odours is extremely difficult due to the variety of sources of odour and the often very low ppb concentrations that produce odour. However, some industries and applications have a known source of odour resulting from compounds such as mercaptans, hydrogen sulphide, ammonia, typically from industries such as pulp and paper manufacturing, fertiliser production or natural sources such as rotting vegetation. Ecotech is able to offer extremely sensitive instrumentation and systems that enables the low ppb monitoring of these species down to 1 ppb, fully integrated with our data evaluation and reporting software.
