A group at Texas A&M University (College Station, Tex.; is developing a process that converts organic municipal solid waste (MSW) into straight-chain alkanes, a primary component in gasoline. The four-step process (diagram) begins with a proven industrial waste-sorting method (using vibration, magnetism and air currents) that isolates the organic, digestible portion (typically food...

Technology developed by Algal Scientific Corp. (Northville, Mich.; uses algae to remove soluble organics, nitrogen and phosphorous from medium- to high-strength wastewaters in a single step. The technology is an alternative to multistep treatment processes involving the use of bacteria and chemical treatment. The...

The effluent discharged by domestic industries in Japan amounts to approximately 11.1 billion ton/yr. Most of this waste is comprised of relatively low concentrations of organic matter. Today, most of this effluent is treated by aerobic biotreatment (activated sludge). However, activated sludge treatment not only consumes large amounts of electric power needed to run blowers or fans, but it also produces...

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...

GE Power & Water (Trevose, Penn.; 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...

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...
