  • A Critical Evaluation of the South African Air Quality Offsets Guideline

    There is wide recognition in South Africa to the link between the quality of life and quality of the air we breathe. The Department of Environmental Affairs (DEA) attempts to improve air quality through two key regulatory tools; emission limits, which regulate the maximum concentration of certain pollutants permissible within certain, ‘listed’ industrial stacks or vents, and ambient ...

  • Integrated membrane systems incorporating coagulation, activated carbon and ultrafiltration for the removal of toxic cyanobacterial metabolites from Anabaena circinalis

    The use of integrated membrane systems (a train of treatment processes incorporating one or more membranes) is increasing globally as the technology is very effective for the production of high quality drinking water. In this investigation a laboratory scale integrated membrane system (IMS) featuring coagulation, powdered activated carbon (PAC) and ultrafiltration (UF) was investigated for the ...

  • In Situ Sediment Treatment Using Activated Carbon: A Demonstrated Sediment Cleanup Technology

    This paper reviews general approaches for applying activated carbon (AC) amendments as an in situ sediment treatment remedy. In situ sediment treatment involves targeted placement of amendments using installation options that fall under two general approaches: 1) direct application of a thin layer of amendments (which potentially incorporate weighting and/or binding materials) to surface ...

  • Understanding the contribution of biofilm in an integrated fixed-film-activated sludge system (IFAS) designed for nitrogen removal

    The objective of this study is to improve knowledge on the integrated fixed-film-activated sludge (IFAS) system designed for nitrogen removal. Biofilm growth and its contribution to nitrification were monitored under various operating conditions in a semi-industrial pilot-scale plant. Nitrification rates were observed in biofilms developed on free-floating media and in activated sludge operated ...

  • Environmental toxicity of PFCs: An enhanced integrated biomarker (EIBR) assessment and structure‐activity analysis

    Perfluorinated chemicals (PFCs) are a group of compounds with varying carbon chains and functional groups. However, available toxicity study is mainly limited to dominant species. While many other PFCs are detected in the environment and biota, it is important to extend toxicity study to different types of PFCs to better assess their environmental and ecological impacts. In the present study, ...

  • Separation of hydrophobic organic compound from surfactant solutions with activated carbon in a fixed bed

    The adsorption behavior of phenanthrene (PHE) in Triton X-100 (TX100) solutions with fixed activated carbon (AC) bed was studied to recover the surfactant. The effect of various parameters like bed depths, flow rates, influent TX100 concentration, and influent PHE concentration were investigated. The breakthrough time of both TX100 and PHE increased with the increase of bed height and decrease ...

  • Integrated maximum efficiency air pollution control system

    A major uranium refiner required an air pollution control system to control emissions from their hazardous incinerator. The presence of radioactive material demanded that outlet emissions approach non-detectable levels. Macrotek was contracted to design and supply the system. Advanced, cutting edge technology was used to design a system with the lowest possible emissions, which has been ...

  • Compost integral in new website in building soil

    A website called “BuildingSoil” has been launched by the Washington Organic Recycling Council to help builders preserve healthy soil on building sites. It's the latest Soils for Salmon project which aims to change standard site development practices. These new “soil best management practices” will soon be required by local governments around western Washington, as they update local codes to ...

  • DEFRA carbon initiatives break ground

    Say what you like about their propensity for acronyms, but the British have also made significant strides forward in the arena of climate change recently. To better approach the situation, they combined DEFRA and BERR within the DECC and then proceeded to make a significant step forward with the first issue of legally binding legislation within a national carbon trading scheme.There has been a ...

  • UK Carbon Reduction Commitment (CRC)

    Energy Efficiency Reduction Bill a Benchmark for Others?The pressure has been growing on individual companies, producers and emitters of greenhouse gases to try and restrict the output. Up until this time, it has been voluntary to report carbon emissions but legal initiatives are now underway to make this mandatory. A carbon reduction bill has already been put in place in the UK and may soon come ...

  • What carbon footprint? Asks Corus

    Problem In case you haven’t heard, our planet is getting warmer. At what rate it is occurring or how much human activity has to do with the increasing temperatures is a heated debate, pardon the pun. One thing we do know for sure…carbon dioxide (CO2) is a contributing factor in global warming and humans are responsible for a large portion of these emissions. If you had asked ...

  • The Benefits of Integrated Environmental Data Management - a Waste Industry and Regulator Perspective

    This paper presents the benefits of using integrated data management software to improve the efficiency of waste operations, and the flow of information between operators, regulators and any other stakeholders such as local communities. Further benefits such as automatic reporting of key performance indicators, carbon emissions and benchmarking companies are also discussed. Waste management ...


  • An overview of current household waste management in Indonesia: development of a new integrated strategy

    One of the main problems of current socio–economic activities in Indonesia is how to deal with the increasing amounts of household waste generated in urban areas. This paper discusses the main issues of the current management of household waste in Indonesia and analyses its socio–economic factors as well as introduces a new strategy to utilise and reduce household waste for current and future ...

  • ISCR-Enhanced Bioremediation Accelerates Groundwater Cleanup at Active Manufacturing Facility

    In the winter of 2008, full-scale in situ chemical reduction (ISCR) was implemented as a removal action at the Siltronic Corporation site in Portland, OR, to treat a source area contaminated by releases of TCE. The source area was considered to be the portion of the site with concentrations of TCE in groundwater greater than 11,000 µg/L, suggesting the ...

  • Carbon tax and energy resource in Indian power sector

    Abstract: Global warming is a universal problem nowadays. The recent United Nations Climate Change Conference in Copenhagen was partially successful because all participating countries realised the damages caused by greenhouse gas (GHG) emissions and promise to mitigate in the future course of time. India has also promised to reduce 20% to 25% of these emissions up to the year 2020. To implement ...
