Biofilm-mediated wastewater remediation has been developed as one of the most promising, inexpensive, and environmentally friendly technology it breaks down contaminants via biotransformation, bioaccumulation, biomineralization, biosorption.

Lauren L. Murphy: The Effects of Viscosity and Subsurface Heterogeneity on a Brine Barrier Approach to DNAPL Remediation (Under the direction of Cass T. Miller) Dense nonaqueous phase liquids (DNAPLs) are a long-term source of groundwater contamination. Difficulties of current remediation methods have led to the study of a novel brine barrier remediation technology (BBRT) which presents a solut...

Uranium plays a key role in nuclear power supply, demand of which is growing up with time because of its prospective features. Persistent increase in different nuclear activities leads to increase generation of nuclear wastewater containing uranium. Separation and recovery of the uranium from its unconventional source like nuclear wastewater is worth to explore for addressing the reutilisation ...

This paper reviews the development of ex-situ soil treatment technologies over the last 20 years, against the background of developing legislation and market forces. Legislation along the lines of site remediation, soil treatment, landfilling and reuse was developed and improved in the eighties and nineties. In addition, substantial budgets were made available by the national government to tack...

Microplastics are pollutants highly stable to complete biodegradation and require more specific separation processes for their removal. Classification potential remediation technologies, such as membrane technology, discussed in this review.

Mercury is a highly toxic heavy metal and the ability of the neurotoxin methylmercury to biomagnify in the food chain is a serious concern for both public and environmental health globally. Because thousands of tons of mercury are released into the environment each year, remediation strategies are urgently needed and prompted this study. To facilitate remediation of both organic and inorganic f...

Phytoextraction is a remediation technology that uses plants to remove heavy metals from soil. The success of a phytoextraction process depends on adequate plant yield (aerial parts) and high metal concentrations in plant shoots. A pot experiment was conducted to investigate the combination effects of plants [sunflower (Helianthus annuus) and canola (Brassica napus)] with soil treatments (manur...

a ABSTRACT The Intelligent Systems and Robotics Center (ISRC) at Sandia National Laboratories (SNL) is developing technologies for glovebox size reduction in the DOE nuclear complex. A study was performed for Kaiser-Hill (KH) at the Rocky Flats Environmental Technology Site (RFETS) on the available technologies for size reducing the glovebox lines that require size reduction in place. Currently...

BACKGROUND Assessment of soil arsenic (As) bioavailability may profoundly affect the extent of remediation required at contaminated sites by improving human exposure estimates. Because small adjustments in soil As bioavailability estimates can significantly alter risk assessments and remediation goals, convenient, rapid, reliable, and inexpensive tools are needed to determine soil As bioavailab...
