    Gas analysis & monitoring system for dust

    Particulate matter, suspended particulate matter, atmospheric dust, particulate matter, total suspended particulate (TSP), are terms that commonly identify the group of substances suspended in the air (fibers, carbon particles, metals, silica, polluting liquid or solid). Particulate matter is the pollutant that is now considered the greatest impact in urban areas, and is composed of all those solid and liquid particles dispersed in the atmosphere, with a diameter ranging from a few nanometers to 500 microns and above (ie billionths of a meter to half a millimeter).

    Ambient air monitoring by FID detection – airmoVOC BTEX

    Urban pollution is a problem that concerns more and more people in charge of public health. In large cities, car emissions are an important source of atmospheric pollution. This problem is growing as the traffic keeps on increasing. BTEX compounds are present in car emissions. It is therefore important to be able to analyze them with short analysis cycle duration and on a continuous and automatic way.

    Ambient Stations for Ambient Air Quality Monitoring

    Ambient air monitoring involves the measurement of `representative` air in urban, industrial and rural areas. These measurements are used to determine the human exposure to pollutants and can be combined with trace/background monitoring.

    Waste water treatment plants Personnel Safety & H2S filter management

    Context & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. As a result of the confinement of the waste water stations, toxic components such as H2S and Methylmercaptan increased. Safety of employees on such working sites has therefore become of major problem. To fight this hazardous pollution, air filtering systems have been installed. For the station managers, personal safety coupled with the need for constant air quality control and filter change has been a heavy task.

    Waste water treatment plants Air quality control by TRS MEDOR

    Context & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. At the entrance of the waste water plants, where the waste water arrives, strongly smelling and polluted air is captured and neutralised by a chemical cleaning process called ‘’Stripping’’. The correct amount of chemical products needed to neutralise the polluted air has to be calculated.

  • Roadside monitoring

    Traffic, especially in urban locations, is one of the greatest contributors to air pollution. Traffic produces a variety of different pollutants that include particulates, NO2, NO, CO, hydrocarbons and in some cases SO2. The monitoring of roadside pollution can be challenging as often it is difficult to find suitable locations for large air quality monitoring systems and many sites that are available can be too far away to be representative of roadside air pollution.

  • Noise and vibration monitoring for city monitoring

    Noise has become the primary source of environmental disturbance. In 2002, the European Union took decisive action in the form of directive 2002/49/CE relating to the assessment and management of environmental noise. Through the use of strategic noise mapping, every urban community must implement an action plan to combat noise pollution. The monitoring of noise levels in urban environments is therefore an essential factor.

  • Traffic Emissions Monitoring

    Traffic, especially in urban locations, is one of the greatest contributors to air pollution. Traffic produces a variety of different pollutants that include particulates, NO2, NO, CO, hydrocarbons and in some cases SO2. The monitoring of roadside pollution can be challenging as often it is difficult to find suitable locations for large air quality monitoring systems and many sites that are available can be too far away to be representative of roadside air pollution. Roadside pollution concentrations can change quickly as types and volume of traffic changes and so instrumentation used must be able to cope with these rapidly changing conditions. Ecotech has established a wide variety of roadside monitoring stations incorporated both into large walk-in style shelters to compact monitoring shelters. Our solutions can be tailored to your needs. Ecotech`s compact solution uses a compact monitoring shelter fitted out with a variety of analyzers and particulate monitors. These analyzers offer fast response, minimal maintenance and are widely used for roadside monitoring.
