  • Technology: clean air’s unsung hero

    Last year, we celebrated the 40th anniversary of the U.S. Clean Air Act (CAA) and the 20th anniversary of the 1990 Amendments to the CAA. The CAA has been a huge success. From 1990 to 2008, emissions of six common pollutants were down 41%, while gross domestic product grew 64%. Emissions of volatile organic compounds dropped 31%, carbon monoxide dropped 46%, and sulfur dioxide dropped 51%. Lead ...

  • Climate change & clean technology: from challenge to opportunity

    Over the past few years, climate change and sustainability have been catapulted to the forefront of headline news. As ongoing public pressure for improved environmental stewardship continues to mount, governments are actively pursuing legislation, including regulations, to accelerate positive change. We have already witnessed significant regulatory, policy and legal changes related to lower ...

  • New Nozzle Technology “Cleaning More with Less”

    This technical paper will explain the new nozzle technology developed by Scientific Dust Collectors that allows high air-to-cloth ratio baghouses to use 80psig of compressed air instead of the industry standard 100psig.   The reverse pulse jet baghouse has been around for over 50 years and the cleaning cycle has not changed very much during that time. The cleaning cycle is the most important ...

  • Dry/Wet Scrubbers for Clean Air Compliance

    Air-scrubbing venturis and towers may be the answer to clean air compliance for small- to medium-sized companies. Forthcoming requirements of the Clean Air Act Amendments of 1990 will inventory many more specific chemicals considered hazardous. From acetaldehyde to xylenes, the list regulated under the air taxies program includes 189 hazardous air pollutants (HAPs). That number may ...

  • Clearing the air on “free Air CFM” - Specs for portable duct cleaning vacuums

    Many times when researching equipment for duct cleaning vacuums you will find manufacturers posting the CFM suction ratings on their vacuums as “Free Air” or “bench Test”. The Free air test is the rating on the impeller wheel of the vacuum, simply put it is the maximum amount of airflow the impeller can produce with out any restriction. It seems as though many ...

  • Present status and future prospect of clean coal technology in China

    Coal consumption accounts for about two thirds of the primary energy consumption in China. High economic growth has brought about a rapid increase of coal consumption. Low-efficiency combustion of a large amount of coal caused coal-smoke related air pollution. The Chinese government put forward plans to develop clean coal technology in the early 1990s, and has listed it as one of the emphases for ...

  • Big Clear Sky – A short history of the Clean Air Act

    Major advances over 50 years have led to cleaner air and groundbreaking technology. The detrimental impact of industrialization to air quality in the United States went unchecked through federal legislation for most of the first half of the 20th Century. But following the 1948 industrial catastrophe in Donora, Pennsylvania – where a cloud of smog killed 20 and injured thousands – regulation of ...

  • Is `clean` coal possible?

    VANCOUVER, April 18, 2007 (GLOBE-Net) - Coal is the world’s most commonly used fuel to produce electrical energy, and will continue as such for some time. Yet it is one of the ’dirtiest’ of all fossil fuels. It is a major source of toxic air pollutants and the leading source of energy-related greenhouse gas emissions. Many believe ’clean coal’ technologies will improve the energy efficiency of ...

  • A global clean fossil scenario

    In this article, a so-called Clean Fossil Scenario (CFS) [1], valid for the year 2050, based on a bottom-up demand analysis, is described. It is proposed to mitigate the rise of atmospheric CO2 concentrations by disposing of the CO2 in deep sea and in other reservoirs to limit its liberation to the air. The scenario is clean, because emissions to the environment are reduced drastically compared ...

  • The natural way to clean wastewater

    John Todd founded Ocean Arks International in the 1980s, where he started to experiment with processes that mimic natural ways to purify wastewater. He built a greenhouse and ran sewage through a series of tanks, with plants suspended in the flowing waters, and constructed marshes made of sand and gravel. No chemicals were added, but plenty of aquatic creatures from snails to small fish were ...
