  • Keeping APCr out of Landfill

    The CIWM have recently featured an article by our very own Dr David Deegan in the latest edition of their magazine. The article explains why Tetronics International were unhappy to be informed recently that Defra ministers had taken the decision not to remove the ...

  • Controlling Pharmaceutical Coating & Drying Process Emissions

    Capturing and destroying harmful emissions from pharmaceutical processes can be challenging. It’s not because the volatile organic compounds (VOCs) are difficult to destroy using catalytic or thermal techniques. It’s because their concentrations can be so high. These process streams raise safety concerns, both when they’re collected in vents and when they reach the final ...

  • Thermodynamic efficiencies and GHG emissions of alternative desalination processes

    Three alternative approaches to desalinating seawater were evaluated with respect to their thermodynamic efficiencies and greenhouse-gas emissions. The technologies considered were multistage flash distillation (MSF), reverse osmosis (RO), and membrane distillation (MD). The analysis was based on published stream data from large-scale operational MSF and RO facilities and experimental-scale data ...

  • Case study - Destruction of inert process emissions

    Many chemical companies use batch reactors to make their products.  These reactors typically have vents which are opened and closed during emptying, filling, mixing, heating or cooling and other steps of the production process.  The gases coming from these vents must be controlled under most government regulations.  Generally speaking, the emissions produced are inert (little or no ...

  • Emission Control Strategies and Technologies for the Chemical Processing Industry: An interview with Chris Anguil

    AC: Could you please provide our readers with a brief introduction to the industries that Anguil Environmental works within? CA: Our thermal and catalytic oxidizer systems are applied on any industrial process that is regulated for Volatile Organic Compounds (VOCs), Hazardous Air Pollutants (HAPs) or Nitrogen Oxides (NOX). Some of these industries include chemical ...

  • Modeling Greenhouse Gas Emissions From Activated Sludge Processes

    Dynamic simulation of activated sludge process is a common tool for wastewater treatment design and optimization. Most activated sludge models predict only the uptake of BOD and nutrients, however, they can easily be supplemented with further information regarding greenhouse gas (GHG) production to predict the generation of components such as CO2. Many published anaerobic digestion models contain ...

  • Wastewater treatment process impact on energy savings and greenhouse gas emissions

    The objective of this research was to assess the energy consumption of wastewater treatment plants (WWTPs), to apply a mathematical model to evaluate their carbon footprint, and to propose energy saving strategies that can be implemented to reduce both energy consumption and greenhouse gas (GHG) emissions in Greece. The survey was focused on 10 WWTPs in Greece with a treatment capacity ranging ...

  • Nitrous oxide emissions from one-step partial nitritation/anammox processes

    Measurements of nitrous oxide were made at pilot- and full-scale plants to evaluate greenhouse gas emissions from one-step partial nitritation/anammox processes applied in moving bed biofilm reactors treating reject water. It was found that 0.51–1.29% and 0.35–1.33% of the total nitrogen loads in the pilot- and full-scale reactor, respectively, were emitted as nitrous oxide. Between 80 and 90% ...

  • Effect of carbon sources on nitrous oxide emission in a modified Ludzak Ettinger process

    Effect of methanol and glycerol on nitrous oxide (N2O) emission in two laboratory-scale modified Ludzak Ettinger (MLE) processes was investigated during three distinct periods: dissolved oxygen (DO) control by intermittent aeration with a DO controller, and high and low aeration rates. N2O consumption rate in an anoxic tank and aeration mode influenced N2O emission rates from ...

  • Separate determination of PM10 emission factors of road traffic for tailpipe emissions and emissions from abrasion and resuspension processes

    Little is known about the relevance of mechanically produced particles of road traffic from abrasion and resuspension processes in relation to the exhaust pipe particles. In this paper, emission factors of PM10 and PM1 for light and heavy-duty vehicles were derived for different representative traffic regimes from concentration differences of particles and nitrogen ...

  • Interpreting the IPCC emissions scenarios

    This paper discusses how two sets of emissions scenarios, generated using the Atmospheric Stabilization Framework, were used by the United Nations Intergovernmental Panel on Climate Change (IPCC). In particular, it discusses how the scenarios were specified, what roles models played in developing the scenarios, and how the scenarios were interpreted by participants in the IPCC process. It draws ...

  • Effective control of fugitive emissions

    Are you Building a brand new process and want to get through the permit process quickly? Looking for ways to further reduce emissions? Under an order from U.S. Environmental Protection Agency (EPA) to further reduce emissions? With EPA continually pressuring industry to reduce emissions, control of fugitives is increasingly important to your overall emissions ...

  • Making money by reducing emissions

    Efforts to reduce emissions are really about changing companies' behavior. Pressure on companies from various activist groups combined with daily headlines in national and international media are driving various agendas among federal, state and local regulators. The current financial crisis does not appear to have lessened this pressure, rather the opposite. Compliance is now a must; ...

  • Emissions reduction with Diesel blending

    Diesel technologies are develops by huge rates. Modification of cars with diesel engines make a half of the new cars sold in Europe. The black smoke, noisy engine operation and unpleasant smell remained far in the past. Today diesel engines present not only profitability, but also high capacity and worthy dynamic characteristics. Quality of fuel also is changed. The modern diesel blending has ...

  • Tackling remediation emissions

    Organisations commissioning regeneration projects now have the option to substantially reduce the carbon emissions associated with any remediation project, while offsetting the remaining carbon impact of these works, says Joe Teer, operations director of QDS. QDS introduced a carbon neutral remediation (CNR) service earlier this year triggered at this particular time by the fact ...

  • N2O emission in short-cut simultaneous nitrification and denitrification process: dynamic emission characteristics and succession of ammonia-oxidizing bacteria

    A sequencing batch airlift reactor was used to investigate the characteristics of nitrous oxide (N2O) emission and the succession of an ammonia-oxidizing bacteria (AOB) community. The bioreactor could successfully switch from the complete simultaneous nitrification and denitrification (SND) process to the short-cut SND process by increasing the influent pH from 7.0–7.3 to 8.0–8.3. ...

  • Metal Coating Emission Control

    The use of regenerative thermal oxidizers is expanding into applications where they wouldn’t have been considered years ago, says Mike Scholz As the first generation of oxidizer systems in the industry nears the end of their service life, many canmaking plants face repair or replacement of their existing air pollution control systems. Like many others in the industry, a Silgan canmaking ...

  • Performance of the low-emission flare

    Job report / Elbisgraben (Bale / Switzerland) The summer of 1992 had finally arrived. The 5MW low emission furnace in the district heating station Liestal was ignited, supplied with landfill gas from Elbisgraben landfill. Since then the plant has been running continuously and the comprehensive measurements taken, verify that all targets aimed at have been achieved: plant ...
