  • Real time odour monitoring: odour abatement monitoring using electronic noses.

    The equipment implemented to reduce odour emissions is designed with effectiveness in mind. However, some operating conditions may reduce that effectiveness without an industrial site being able to detect this quickly. Processes that most of the time have low odour emissions may become, under certain weather conditions, a major nuisance source. An electronic nose system can detect odour before ...

  • Electronic nose sniffs out odour pollution

    The science of smell is set to enhance air quality in the UK, thanks to the development of a pioneering ‘electronic nose’ for industrial odour monitoring.   Available in the UK for the first time, the technology can be used to help improve the control of odours associated with industries such as waste storage and recovery, sewage treatment, composting, chemicals and food ...

  • The need for electronic noses for environmental odour exposure assessment

    This paper focuses on the opportunities for using electronic noses for odour exposure assessment purposes, especially in cases where dispersion modelling is not applicable. Such cases include, for instance, those sources where a detailed characterisation and quantification of the odour emissions for every hour of the simulation time domain is particularly difficult, due to the nature of the ...

  • Is H2S a suitable process indicator for odour abatement performance of sewer odours?

    Odour abatement units are typically designed and maintained on H2S concentrations, but operational failures are reported in terms of overall odour removal, suggesting a wide range of malodorous compounds emitted from sewers that may not be efficiently removed by existing odour abatement processes. Towards providing greater insight into this issue, several activated carbon filters and biofilters ...

  • Roof over primary settling tanks to prevent air pollution and odours

    The Wastewater Purification Plant (EDAR) in Cambrils, Tarragona, was the setting for a solution deployed by Bioconservación, a gas absorption and air purification specialist. The project involved covering over the settling tanks to prevent hydrogen sulphide dissolved in the water from polluting the surrounding air. The H2S (hydrogen sulphide) dissolved in water as it arrives at the tank in ...

  • Development of a diagnostic tool: the wastewater collection network odour wheel

    The assessment of nuisance odour problems and the application of an effective odour management programme for the associated industrial activity may be achieved using a representative odour wheel and Odour Profile Analysis methodology. The odour wheel is a very useful tool for conducting odour quality control monitoring and developing a constructive dialogue regarding nuisance odours with the ...

  • 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 ...

  • Online Process Analyzer Installed at F.J. Horgan WTP to Monitor Chloramination

    Construction was completed on the City of Toronto's F.J. Hor-gan Water Treatment Plant in 1979, more than 60 years after chloramine had first been used to disinfect drinking water in an Ottawa plant. By then there was little debate about the benefits of chloramination and it was incorporated into the new plant's design as part of the disinfection process. Chloramine is more stable than free ...

  • Long-term noise monitoring – how a new approach leads to a better result

    Good Neighbours Limit their Noise Impact Long-term noise monitoring has taken place in various applications for many years. Business such as airports, power stations, refineries, mines, etc., may be required to perform continuous noise monitoring to ensure legal operating conditions are not breached, and to demonstrate to local authorities and communities that the business continues to be a good ...

  • peCOD is the New NOM Monitoring Tool for Measuring Organic Reactivity - Case Study

    Natural organic matter (NOM) is a critical parameter for measuring drinking water quality.  Levels of NOM are associated with taste, odour, colour, chemical treatment dosage, and disinfectant by-product (DBP) formation.  There are several tools accepted by drinking water quality experts which are used to evaluate NOM: total organic carbon (TOC), dissolved organic carbon (DOC), UV254, ...

  • In practice: M2M technology and H2S

    Coping with H2S is a crucial topic. Besides causing unpleasant odours, hydrogen sulfide can also lead to corrosion of important components as well as damages to health. Microtronics supports experts in water and wastewater treatment in coping with H2S with various M2M products and a platform. In practice there are different forms of applications. The measurment and transmission of ...

  • Formaldehyde - Sources, Health effects and Safety

    Formaldehyde is a colourless gas with a characteristic pungent odour. It's widely used in many industries and causes severe health issues if used inappropriately. In order to ensure employees and the public are not exposed to dangerous levels of Formaldehyde in the air, it is advised to detect and monitor levels with a suitable detection instrument, especially in industries and buildings where ...

  • Evaluating the potential of an electronic nose for detecting the onset of anaerobic conditions during composting

    Most bad odours in composting plants are formed under anaerobic conditions and often they could be avoided if detected early enough. In this project an electronic nose was used to evaluate the odours produced during a composting process at bench scale. The electronic nose consists of an array of electronic chemical sensors with partial specificity and an appropriate pattern recognition system ...

  • Invasion of the non-indigenous nuisance mussel, Limnoperna fortunei, into water supply facilities in Japan

    The aquatic nuisance mussel, Limnoperna fortunei, arrived in Japan before 1987 possibly with the Asian clam imported as food from mainland China. Now the mussel’s distribution has spread to two river systems in central Japan. Water authorities reported several cases of damage caused by L. fortunei. Most cases of damage were caused by dead mussels clogging small diameter pipes for raw water ...

  • SCORe-CT: a new method for testing effectiveness of sulfide-control chemicals used in sewer systems

    A new method for testing the effectiveness of chemical products for sulfide control in sewers is reported. The method, called SCORe-CT (Sewer Corrosion and Odour Research – Chemical Testing), consists of two specially designed laboratory-scale systems that mimic sulfide production in real rising main sewers, and a multi-phase and multi-facet testing protocol. The monitoring tools/methods include ...

  • Holmestown waste management facility, Wicklow, Ireland

    AFS were appointed by Wicklow County Council to design, build and install a flaring system that would last the life-cycle of their new waste management facility. We designed a flare that could safely extract gases being generated by the new facility; the flare could operate at up to 2000m3/hr but would also operate effectively at very low flow rates. The current configuration includes a ...

  • Verification of an alternative sludge treatment process for pathogen reduction at two wastewater treatment plants in Victoria, Australia

    At South East Water wastewater treatment plants (WwTPs) in Victoria, Australia, biosolids are stockpiled for three years in compliance with the State guidelines to achieve the highest pathogen reduction grade (T1), suitable for unrestricted use in agriculture and landscaping. However, extended stockpiling is costly, may increase odour nuisance and greenhouse gas emissions, and reduces the ...
