  • 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 ...

  • Synthetic media biofilter eliminates hydrogen sulphide and other reduced sulphur compound odours

    Abstract Innovative synthetic biofilter media has revolutionized biofilter technology for removal of hydrogen sulphide (H:S) odours from several wastewater treatment facilities across North America. The major drawback of biofilter technology in the past was use of organic wood-based media, which had several problems including high-pressure drop, frequent media replacement, lack of ...

  • Biofilters vs Asdorption

    In the last three decades biological technologies have emerged as a sustainable and economically-viable alternative compared to traditional techniques like adsorption/absorption for purifying gases. They were well-received initially in the industry and interesting products with good results were carried out for several years. However, owing to a series of reasons that will be detailed in this ...

  • 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 ...

  • The simple, effective and economical treatment of odourous emissions

    The odours from an anaerobic digester and a waste handling depot were fed to two large biofilters with wood chip packing. The seeding of the biofilters was carried out using a microbial product, BFL Odour Clean. For the initial seeding of the biofilter with microbial cultures a manual method of application was used. Careful application of the product to the entire filter bed is key to the success ...

  • Odour control on waste water treatment plants and pumping stations using DMT biotrickling filtration

    Lengthy detention times and warm weather / climate leads to septic waste water producing copious amounts of not only hydrogen sulphide, but also ammonia, organic sulphides, mercaptans, bringing numerous odour complaints on waste water treatment plants ( WWTP’s ) and pumping stations. An odour abatement unit therefore will have to treat not only hydrogen sulphide, but also other pollutants ...

  • Manic 5 and Manic 5 PA (Hydro Québec), Quebec case study

    Part of an hydroelectric complex counting four dams, Manic 5 and Manis 5 PA are two power houses installed in the valley of the Manicouagan river, north of Québec. Unveiled in 1970, this plant represents the higher multiple-arch and buttress dam in the world. For the Manic 5 and Manic 5 PA sanitary water treatment, Hydro-Québec mandated the Groupe-conseil TDA to find a compact ...

  • 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 ...

  • Elimination of NH3 and odor from composting by biotrickling filter and preliminary exploration on molecular biology

    A biotrickling filter was focused on treatment of odorous NH3 gas, along with volatile organic compounds (VOCs) and other odorous gases during cattle manure composting. The biotrickling filter could treat NH3, the main composition, with removal efficiencies of close to 100% because NH4+ was bio-oxidized in the biofilm to NO3− resulting final NO3− concentrations of about 1000 mg/L. Results of ...
