A new vision for clean air

When President George H.W. Bush signed into law the Clean Air Act Amendments (CAAA) of 1990, he put in place a precedent-setting statute that completely revamped our nation’s approach to improving air quality. That statute was an earnest commitment to environmental protection; the comprehensive air pollution control strategy established in it provided state and local regulators with tools to make ...

In the queue for clean air

The National Emissions Ceilings Directive (NECD), adopted in 2001, defines the maximum emissions on a national level for four major air pollutants that have a high impact on human health and the environment. These are: sulphur dioxide, nitrogen oxides, volatile organic compounds and ammonia. The Directive will undergo revision in 2008, which would set new interim air quality targets and related ...

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 ...

Keep your air clean with Wet Dust Collectors

Wet dust collectors use liquid — often but not always simple water — to capture and separate dust, mist, fumes, and other particulate matter from a stream of flowing gas — often but not always simple air. Some wet dust collectors spray liquid in a sheet across the stream of gas; others bubble the gas through ...

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 ...

Air/water cleaning for the control of particulate fouling

Fouling of feed spacers in spiral wound membrane elements due to particulate fouling and biofouling is one of the main operational problems of nanofiltration or reverse osmosis membrane plants. Removal of particulate fouling from spiral wound membrane elements is investigated using frequent air/water cleaning (AWC). In a pilot setup two spiral wound elements were operated in parallel and were fed ...

Two Landmark Interpretations of the Clean Air Act

The most recent U.S. Supreme Court term is notable for two landmark interpretations of the Clean Air Act (CAA). In Massachusetts vs. EPA (U.S., No. 05-1120, 4/2/07), the court held that greenhouse gases (GHGs) are air pollutants subject to regulation under the CAA, overruling an interpretation by the Bush administration. In Environmental Defense vs. Duke Energy Corp. (U.S., No. 05-848, 4/2/07), ...

Air bubbles enhance membrane cleaning: a future perspective

Abstract Air bubbles generated using a novel micro-bubble generator have displayed a dramatic enhancement in cleaning efficiency when used in conjunction with specially formulated cleaning chemicals. In order to establish the effect of this application on membrane performance, a series of experiments were conducted using both a flat sheet test rig and a small scale pilot plant. ...
