  • Quantitative analysis of automotive exhaust gas by Fourier Transform Infrared spectroscopy

    For monitoring gaseous emissions from muffler, instruments presently used can only measure quantitatively a given pollutant. Fourier Transform Infrared (FTIR) spectroscopy can provide quantitative and online real time analysis. Calibration of our FTIR spectrometer with CO, CO2, NO, NO2 and N2O was done and the limits of quantification obtained were shown to be as low as 80 ppm. The variation ...

  • Enhancing Biological Nutrient Reduction in Advanced Individual Onsite Wastewater Treatment Systems

    ABSTRACTAdvanced onsite systems need to continue to improve wastewater treatment through nutrient reduction. Some advanced onsite systems have been shown to reduce nutrients significantly. However, with modifications, these systems can reduce total inorganic nitrogen (TIN) to an even greater degree, and nitrate to levels below federal drinkingwater standards. INTRODUCTIONNitrogen compounds in ...

  • The challenges and benefits of local air quality monitoring

    A new generation of air quality monitors is now being offered to provide localised, real-time air quality readings – but the potential benefit is only just starting to be realised. It is generally accepted that whilst measurements from air quality reference stations are highly accurate, they are not sufficiently location-specific. Key pollutants – such as NO2 and PM2.5 ...

  • Wastewater treatment plant monitors Greenhouse Gas emissions - Case study

    Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...
