  • Monitoring NH3, N2O, CO2 and CH4 emissions

    In France, as in other countries, there is a need to improve knowledge of greenhouse gas and ammonia emissions from livestock production with various management options. The aim of this study was to quantify the NH3, N2O, CO2 and CH4 emissions from two pig solid manure heaps, turned and not turned, in order to examine the effect of turning on gaseous emissions and to obtain additional information ...

  • Fast, simultaneous and continuous monitoring of NOx and NH3 in DeNOx applications

    In DeNOx systems using urea injection with ammonia (NH3) as a reducing agent, the flow rate and control of NH3 must be continuously adjusted and controlled to prevent excess NH3 emissions (slip), to reduce environmental impact and cost of reagents. To optimize this process, it is essential to use an emissions analysis system for simultaneous and continuous monitoring of NOx and NH3. For preparing ...

  • Monitor Volatile Organic Compounds (VOC’s) with PPM Technology’s IAQ Monitor

    Volatile organic compounds (VOC’s) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. VOC’s is one of numerous sensor options that can be incorporated into PPM Technology’s ...

  • Monitoring Multiple Gas Hazards in Ice Arenas

    The equipment used in an arena such as an ice re-surfacer, ice edger, floor sweepers, lift trucks and other special equipment are more often powered by fuel than electricity. The exhaust produced by the gas, propane or diesel fuel powered machines emits, into the air, carbon monoxide (CO), nitrogen dioxide (NO2) and particulates. Ammonia (NH3) is commonly used in the ice chiller mechanical room ...

  • Online Odors Monitoring in Waste Water Treatment Plants

    Odors are very distinct air contaminants as they generate nuisances (see note at the end). 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 automated solution to well identify the origin and the level of odors. Technology Description We offer a ...

  • Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

    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 ...

  • A Comparison of Point Sensors and Open Path Monitors For Toxic Gas (esp. HF) Monitoring

    Point Sensors Ion Mobility Spectroscope (IMS) – a gas sample is ionized by a radioactive source (Ni63). Differences in ion drift under the influence of an applied electric field produce a spectrum that is dependent on the mass, charge, and shape of the component ions. The detector signal and strength is tuned to the drift time of the ion of interest (in this case HF) and signal strength is ...

  • NOx in Non-Utility Industries - Part II - Control options and monitoring methodology

     This the second in a two-part series. Part I, which appeared in our June 2001 issue focuses on air emission origins of nitrogen oxides (NOx) in non-utility industries. Choice of the NOx control technology is dependent on many factors, including regulatory requirements, technical feasibility, cost and public perception. Figure 1, compiled based on publications [1-5], presents a summary of ...


  • Monitoring and control of a partially packed biological aerated filter (BAF) reactor for improving nitrogen removal efficiency

    This paper examines on-off systems and automatic monitoring and control of a biological aerated filter to identify the end point of nitrification and denitrification processes, and chemical oxygen demand (COD), ammonia-nitrogen removal (NH3-N) and aeration savings. Oxidation-reduction potential (ORP), pH and dissolved oxygen (DO) were measured on-line and chemical parameters were measured in the ...
