    Waste water treatment plants Air quality control by TRS MEDOR Online Odor Monitoring

    ontext & 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. Odors are very distinct air contaminants as they generate nuisances. The factors playing a role in the determination of odor annoyance are: odor concentration and intensity, frequency, appreciation, duration, synergy and location. CHROMATOTEC® proposes an automatic solution to well identify the origin and the level of odors.

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.

    Tunnel solutions for the gaseous pollutants

    The TunnelTech 200 series are primarily gas monitors with optional Visibility capability. Most use Infra-red absorption technology to monitor gaseous pollutants and those with a visibility channel use optical attenuation for that application. All TunnelTech 200 analysers except the TunnelTech 205 use the same rugged corrosion resistant enclosures and have an optional Data Display unit. As there is only one moving part so reliability levels are very high and maintenance levels very low.

    CH4 Monitoring in Air

    CH4 (Methane) is a colorless, odorless natural gas that is used in a wide variety of industrial applications such as power generation and chemical production. It is also a byproduct of many biological and geological processes, fracking, and gas drilling. It is highly flammable and creates amounts of carbon monoxide as its combustion byproduct. Methane needs constant monitoring in waste water treatment (for co-generation) and to ensure proper process control (e.g. to determine burning efficiency). A quality CH4 analyzer that is able to provide continuous monitoring is a perfect solution for this.

    Ambient air quality monitoring at airports

    To measure the ambient air quality at airports is a challenge. The monitoring site needs to be representative for background levels and not dependant on changes in local traffic. A large number of gaseous components need to be measured with high accuracy and high availability. The OPSIS DOAS system provides the user with a fast system that gives high availability at low cost. The impact of aircraft take-offs and landings can easily be followed on-line. The OPSIS system can also monitor fugitive emissions from other sources at the airport.

    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.

    Processing of Alternative Fuels for the energy industry

    RDF is a fuel that is normally produced from waste with high calorific value. The original waste comes from households, industry and commerce and is processed for energy extraction; it is meant for co-incineration plants and replaces standard fuels (e.g. coal) in production plants for cement, power plants or other co-incineration plants.
