  • Odour control case study

    A Scottish maggot farm, supplying bait for fishing, faced the problem of dealing with ammonia odours emitted during production. The Scottish Environmental Protection Agency (SEPA) had given the company an emissions discharge consent level of a demanding 5ppm of ammonia. To achieve this the maggot farm commissioned a biofilter to remove the pollutants from the air stream. The design of the ...

  • Biological Odour Control for wheelie bins

    One of the problems with large wheelie bins used for waste storage is that organic deposits build up and these give rise to bad odours. From time to time the bins are washed to remove the organic deposits. However in many cases the odours are not removed so the bin may look clean but not smell clean. There are a number of different types of systems used to wash the bins and BioFuture have worked ...

  • Odour control with Direct Cold Plasma

    Odour emission during the production or processing of food and feed is often an unwelcome side effect. However, by using cold plasma technology, the smell can be reduced up to 95%. Increasingly, feed manufacturers are being required to address the issue of emitting of odour and harmful contaminants into the surrounding community. Local communities, special interest groups and government ...

  • Sustainable odour control in urban environments

    Abstract With an ever increasing focus on sustainability, the municipal recycling sector is increasingly locating recycling facilities in urban environments to be closer to their waste sources. The odour control industry needs to respond in providing ever more efficient odour extraction technologies to minimise any odour nuisance to their residential community neighbours. ...

  • Odour Control at Pesticide Facilities: Eliminating volatile compounds

    Chemical formulation plants are susceptible to emissions of unpleasant and malodorous volatile compounds, a fact which makes the implementation of efficient odour control measures essential. North-western Spain is home to one of the country's oldest industrial sites for the manufacture of phytosanitary products, with some facilities located relatively close to populated areas. Recently, the ...

  • The next generation biological odour control systems

    Odour is usually caused by the presence of hydrogen sulphide, mercaptans (Organic sulphur components) and ammonia, but also multiple other VOC’s (volatile organic compounds) bringing numerous odour complaints at e.g. WWTP’s, pumping stations and composting plants. An odour control system therefore will have to treat not only hydrogen sulphide, but also other pollutants to reduce the total ...

  • High efficiency odour control for wastewater treatment

    Since the banning of sewage sludge disposal at sea in 1998 secondary treatment of sludge is now a vital part of waste water treatment. Initially many water companies opted for incineration, but over the last 10 years other options have been adopted such as producing stabilised sludge and pelletised dried sludge for use as fertiliser for agriculture. Currently over 62% of sludge is used in ...

  • High Rate Biological Odour Control Demonstration for Biosolids Exhausts

    Abstract Biorem has successfully demonstrated its high rate odour control system for biosolids exhausts at Ashbridges Bay sewage treatment plant in Toronto, Ontario. The demonstration used XLD™, a biofiltration media engineered specifically for biosolids odours. The system has achieved 95% odour removal in less than 20-s Empty Bed Residence Time (EBRT) despite high concentration of ...

  • High rate Biological odour control system - Case Study

    ABOUT THE PROJECT Biorem has conducted a successful demonstration of high rate odour control at Preston Wastewater Treatment Plant in Cambridge, Ontario over the last three years. The system treats exhausts from primary clarifier and intermediate pump station. A combination of biotrickling filtration (BTF) and biofiltration (BF) processes was used in a novel horizontal flow ...

  • The benefits of planned maintenance for waste water odour control systems

    Abstract This paper summarises ERG’s experience in the first three years of their odour control maintenance framework agreement with Southern Water and ERG’s perceptions of the benefits Southern Water has derived from this agreement. Key Words Planned maintenance, odour control, chemical scrubbing, bio‐filters, carbon filters, waste ...

  • Odour Nuisance - Where We Are and Where to Next?

    Prior to 1990 there were very few examples of effective odour control schemes at sewage treatment works. Sources were often not properly identified, much less quantified and budgets did not allow the introduction of properly engineered solutions. Since then, in response to a seemingly endless increase in pressure from public, considerable progress has been made tackling the problem. First ...

  • The smell of success. Odour management in sludge treatment

    Production of municipal solid waste (MSW) is increasing worldwide, although many – primarily industrialized - countries are making major efforts to cap that growth. In France, for example, MSW production has tripled over the past 25 years. In 2006, the country produced 30 million metric tonnes of municipal solid waste, with a substantial portion of this waste ending up in landfills. In keeping ...

  • 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 ...

  • Waste Transfer Station Odours - Case Study

    Application Greenstar Ltd. who operate the large waste transfer station at Ballyogan needed to ensure working conditions inside the building were acceptable to the workforce and that the surrounding area did not suffer from odourous emissions. An early part of the design process called for an efficient extraction system to draw air from the Reception Hall and the Baling Hall to meet these ...

  • Evaluating odour control technologies using reliability and sustainability criteria – a case study for water treatment plants

    Technologies for odour control have been widely reviewed and their optimal range of application and performance has been clearly established. Selection criteria, mainly driven by process economics, are usually based on the air flow volume, the inlet concentrations and the required removal efficiency. However, these criteria are shifting with social and environmental issues becoming as important ...

  • Performance of sanitary sewer collection system odour control devices operating in diverse conditions

    Controlling odours from sanitary sewer systems is challenging as a result of the expansive nature of these systems. Addition of oxidizing chemicals is often practiced as a mitigation strategy. One alternative is to remove odorous compounds in the gases vented from manholes using adsorptive media. In this study, odour control devices located at manholes were observed to determine the ability of ...

  • Control of odour nuisance in urban areas: the efficiency and social acceptance of the application of masking agents

    This paper presents and discusses the results of the project named ‘Jasmin’ implemented in Algiers to control the strong odours of the river named Oued El Harrach, one of the largest rivers in the centre of the city. Pending the achievement of curative solutions, a temporary option for mitigation of nuisance odour by masking agents was implemented in the vicinity of the main ...
