New environmental regulations have identified many of the currently used oxidizing agents employed for industrial waste control, disinfection, and wastewater treatment as a caveat that must be addressed. Ferrate has potential for becoming the alternative of choice because of its aggressive oxidation properties and its negligible impact on the environment. However, there has been little industrial ...

Dynaflow, Inc., proposes the development of a novel jet-induced cavitation process for the removal of various pollutants¿including pesticides from wastewater discharge¿ that would be economical, readily applicable to both large- and small-scale systems, and that does not produce potentially hazardous by-products of chlorination and ozonation. Ultrasonically induced cavitation is known to be capa ...

The goal of this project is to develop a portable system for the real-time detection and quantification of adenovirus in wastewater. The system is based on a small, portable flow cytometer that was developed and is being marketed by Becton Dickinson Biosciences (BDB) under the trade name FACSCount¿ for use in selected medical and research applications. Unlike previous efforts to apply flow cytome ...

Chlorinated hydrocarbons represent the most prevalent contaminants of groundwater in the country. When released in the subsurface, they tend to persist below the water table, and it can take decades or centuries before slow-moving groundwater completely dissolves accumulations of chlorinated solvent product. Analytical methods currently available for monitoring these compounds require extensive ...

Heavy metal species mobilized and released into the environment by technological activities tend to persist indefinitely, circulating and eventually accumulating throughout the food chain, posing a serious threat to the environment, animals, and humans. Typical industrial metal-containing discharges can be considered as point-source emissions, which in turn offer the possibility of feasible remed ...

A novel, environmentally benign antimicrobial surface modification based on immobilized quaternary ammonium-functionalized dendrimers is proposed for the prevention of biofilm formation. Dendrimers are unique nanomaterials that have attracted attention as possible antimicrobial agents due to their compact structure, high local charge density of functional surface groups, unique carrier properties, ...

Zebra mussels cause an estimated $5 billion in economic damages annually. They clog water intake pipes, damage water supplies, threaten native fish and aquatic species, and promote the mobilization of toxic materials into the food chain. Chlorination is presently the most common treatment for zebra mussels. However, chlorine causes many serious environmental risks, thus necessitating the develo ...

OmniSite BioDiagnostics, Inc. (OmniSite) proposes to develop artificial receptors composed of DNA oligomers (called "aptamers") for binding and removal of organophosphorous and chlorinated pesticides. Aptamers will be generated by the systematic evolution of ligands by exponential enrichment (SELEX) combinatorial chemistry technique. SELEX aptamers offer several major advantages over antibody tech ...

This Phase I project will develop a multianalyte biosensor field screening instrument (MBFI). The MBFI has the potential to reduce the annual cost of environmental analyses in the United States by more than $20 million and to reduce the analysis turnaround time from approximately 19 days to less than 15 minutes. The major barrier to the development of a biosensor instrument for environmental mea ...

Cutting fluids have been used in machining processes for many years to decrease the temperature during machining by spraying the coolant into the machining zone, directly on the cutting tool and the part. This has the effect of decreasing the tool temperature, which increases tool life and improves the part quality. These benefits come with significant drawbacks. Cutting fluids are environmenta ...
