Methane is an important global warming gas. Large amounts of methane and other light hydrocarbons are produced as solution gas in the production of oil, and as biogas from landfills and animal feedlots. Some of this gas is emitted directly to the atmosphere, some is flared, and some (from the very largest sources) is used as fuel in specially modified turbines or engines to generate electricity.

Cryptosporidium, originating from contamination of public drinking water supplies, ponds, rivers, or swimming pools, have cause large-scale and deadly outbreaks, which became a major cause of waterborne infectious diseases. Since 1991, the percent of outbreaks attributable to Cryptosporidium has doubled, and in the 1993-1994 period, 17 percent of all outbreaks were caused by Cryptosporidium. In 19 ...

It is estimated that there are approximately 300 million tires discarded each year in the United States and this is in addition to the 800 million scrap tires that reside in landfills and tire dumps throughout the country. About 180 million are recycled, and the remaining 120 million scrap tires are discarded (legally or illegally) in landfills or tire dumps. Current tire reuse technologies offer ...

Ships generate large volumes of bilge and ballast water which, to meet new environmental regulations, will require treatment prior to overboard discharge. Such wastewaters contain high levels of emulsified and free-phase oil and suspended solids. Treatment by ultrafiltration can produce dischargeable water, but all currently available membranes are finely porous and only moderately hydrophilic. Th ...

Systems & Processes Engineering Corporation (SPEC) proposes to develop receptors composed of DNA oligomers ("aptamers") from a combinatorial library for binding and detecting Cryptosporidium parvum oocysts and three species of Encephalitozoon spores. Aptamers will be generated by the Systematic Evolution of Ligands by EXponential enrichment (SELEX) combinatorial chemistry technique. SELEX aptamers ...

The occurrence of causative agents such as Cryptosporidium parvum and other pathogens in water supplies presents a critical issue. Transmitted through water and animals, these organisms provide a reservoir of infection, which results in the excretion of the environmentally stable cysts or oocysts that are impervious to inactivation by many drinking water disinfectants. Cryptosporidium infections a ...

This Phase I project is concerned with the development of a simple, cost-effective, environmentally friendly process for the production of potassium ferrate. Lynntech, Inc.'s proposed method can be readily scaled up for the production of industrial quantities of this extremely useful oxidant. Ferrate is an environmentally friendly oxidant that represents an ideal substitute for other oxidants, par ...
