  • Analysis and optimization of ammonia stripping using multi-fluid model

    Ammonia recovery from anaerobic digestion (AD) is a notably beneficial process for removing excess nitrogen, producing low cost fertilizer and enhancing odor abatement. A process was developed for nutrients recovery by integrating a simple and effective stripping process with AD system. To design, optimize and scale up this system, multi-fluid model was developed to simulate flow, mass transfer ...

  • Design, Construction, Installation, and Operation of a Compact Bio-Oxidation System to Manage Odors at the City of Wilsonville WWTP

    ABSTRACTThe 5 mgd Wilsonville WWTP was experiencing odor complaints from the adjacent residential neighborhood. An existing in-ground, bark and wood-chip biofilter was not performing well. In December 2004, the City of Wilsonville contacted BioReaction Industries (BRI) requesting the design of a bio-oxidation system with guaranteed performance criteria. The project required an understanding of ...

  • 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 ...

  • Integrated assessment of Nitrogen losses from agriculture in EU-27 using Miterra-Europe

    Received for publication February 29, 2008. The high N inputs to agricultural systems in many regions in 27 member states of the European Union (EU-27) result in N leaching to groundwater and surface water and emissions of ammonia (NH3), nitrous oxide (N2O), nitric oxide (NO), and dinitrogen (N2) to the atmosphere. Measures taken to decreasing these emissions often focus at one specific ...

  • Performance of activated sludge diffusion for biological treatment of hydrogen sulphide gas emissions

    Odours from wastewater treatment plants are comprised of a mixture of various gases with hydrogen sulphide (H2S) often being the dominant constituent. Activated sludge diffusion (ASD) as a biotreatment system for odour abatement has been conducted for over 30 years but has limited broad application due to disagreement in the literature regarding the effect that ASD may have on wastewater ...

  • The Greening of Carbon Fibre

    Carbon fiber is a material that has, and will continue to revolutionize the products we use every day by making them stronger, lighter and more durable.  Experts estimate that the specialty material is twice as stiff as steel and five times stronger, per unit of weight.   It is made from organic polymers which consist of long strings of molecules held together by carbon atoms.  The ...

  • Industrial wastewater - who discharges what and who pays for the cleanup?

    Canada's renewable water supplies are being threatened by vast amounts of municipal and industrial waste being disposed of in rivers, lakes and other marine areas. Those industries largely responsible are not paying their share for the clean up according to Statistics Canada. The Industrial wastewater business is huge involving water costs of $1.7 billion and water treatment costs of $656 million ...

  • Carbon Fiber Emission Control Strategies

    Problem Carbon fiber (fibre) and graphite reinforced polymers are materials that have, and will continue to revolutionize the products we use everyday by making them stronger, lighter and more durable. However, the manufacturing process can have serious environmental ramifications and immediate danger to human health if careful consideration is not given to emission control at the ...

  • Case study - Wastewater treatment plant - ROPEC - deodorization plan project

    Bioconservacion has recently been awarded the supply of high capacity odor elimination media for two deodorization systems in a waste water treatment plant (WWTP) located in the Canadian capital of Ottawa. The Robert O. Pickard Environmental ...

  • Case study - Carbon fibre: furnace & oven emission control

    Overview A carbon fiber company in China was faced with the challenge of selecting an emission control system for a new pilot line at their specialty fiber products facility. The line would include furnaces and three ovens, both of which would emit Carbon Monoxide (CO), Ammonia (NH3) and lethal amounts of Hydrogen Cyanide (HCN).   Action ...

  • Global solution: Gas and particulate analysis in Cement industry

    Cement plants are increasingly required to install continuous emission monitoring systems (CEMS). While these represent a significant financial outlay, a range of other factors also need to be considered when selecting a suitable CEMS. To the inexperienced, selecting a suitable CEM can mistakenly be considered as simply ensuring that the applicable national regulations (eg MACT in the USA, ...

  • Costs of air pollution from European industrial facilities 2008-2012

    In 2011, the European Environment Agency (EEA) published a first assessment of the costs of air pollution caused by European industrial facilities. The report Revealing the costs of air pollution from industrial facilities in Europe (EEA, 2011) applied a simplified modelling approach to assess the damage costs to health and the environment in 2009, caused by pollutant emissions from industrial ...

  • Monitoring Environmental Quality

    ' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...

  • Water Quality Models

    ' In order to determine the impacts of a particular discharge on ambient water quality, it is usually necessary to model the diffusion and dispersion of the discharge in the relevant water body. The approach applies both to new discharges and to upgrading of existing sources. This note provides guidance on models that may be applicable in the context of typical Bank projects.' Introduction ...
