Physical chemistry principles point to a better way to clean up oil spills
One of the current methods for dealing with oil spills is through the use of dispersants. These dispersants, however, break oil into small globules that sink into the water, spreading the oil into a wider area, and they have toxic effects on the local marine ecosystem. Now, researchers, led by professor Moses O. Tade at the Dept. of Chemical Engineering at Curtin University (Perth, Western Australia...

This new membrane bioreactor cuts energy costs and boosts throughput
GE Power & Water (Trevose, Penn.; ge.com) has introduced an improved membrane bioreactor (mbr) technology whose productivity is said to be 15% higher than that of its predecessor for wastewater treatment plants. The new system, called LEAPmbr, was derived from innovations to GE’s ZeeWeed 500 mbr. Glenn Vicevic, senior manager, Engineered Systems, says the system has been tested on a commercial...

Biodegradation system for VOCs poised for expansion
A system that utilizes existing biological wastewater-treatment facilities for destruction of biodegradable volatile organic compounds (VOCs) and other organic hazardous air pollutants (HAPs) has been demonstrated at three U.S. petroleum-refining and chemical facilities, and the developer has plans to extend the U.S. patent-pending treatment approach to eight additional facilities in coming months. Environ...
