Tersus Environmental Secures Patent Rights for Vadose Zone Remediation by Barometric Pumping
Raleigh, NC, June 26, 2011 --(PR.com)-- Tersus Environmental, LLC, a developer and marketer of advanced, innovative technologies for the remediation of soil and groundwater, and Savannah River Nuclear Solutions, LLC (SRNS) announced that they have signed an Exclusive Patent License Agreement. This royalty-based agreement grants Tersus Environmental an exclusive worldwide license to manufacture, use, and sell the technology known as MicroBlower™, a passive soil vapor extraction technology developed at the U.S. Department of Energy’s Savannah River National Laboratory (SRNL), which is operated for DOE by SRNS.
“This license agreement with Savannah River Nuclear Solutions enables us to expand our strong foundation of intellectual property,” said Gary Birk, Managing Partner of Tersus Environmental. “Working with the outstanding researchers at Savannah River National Laboratory will provide our associates at Tersus Environmental and inVentures Technologies more design freedom as we develop the next generation of remediation technologies to meet the demands of this ever-expanding environmental sector. Our customers will benefit as we continue to implement an expanding array of uniquely effective remediation strategies.”
Targeting the “vadose zone” during remediation traditionally has been considered difficult and the researchers at the Savannah River National Laboratory have developed a MicroBlower™ assisted barometric valve specifically for remediation of organic compounds in the vadose zone.
MicroBlower™ uses a small, low power vacuum blower to extract or inject gases into the subsurface for characterization or remediation. While similar in design to an active soil vapor extraction (ASVE) blower, the MicroBlower™ is a low-cost alternative designed to run on renewable sources of energy such as solar and wind energy to treat volatile organic compound (VOC) contamination in the unsaturated zone. MicroBlower offers the advantage of a reduced carbon footprint and very low operating and maintenance expenses.
A growing trend in environmental remediation is the use of natural processes. Researchers at SRNL are developing remedial approaches that take advantage of natural phenomena. These approaches are reducing the costs of cleanup and intruding less on the environment. The MicroBlower™ technology is an example of such an approach, based on natural venting cycles between the surface and subsurface. When atmospheric pressure is higher than the subsurface’s pressure, air is induced to flow through wells into the subsurface. Conversely, when atmospheric pressure is lower than subsurface pressure, air flows out of wells into the atmosphere, taking with it organic contaminants such as chlorinated solvents in the gas phase.
Tersus Environmental also provides sales management and marketing services for CO2 SWI (Saturated Water Injection) Technology by inVentures Technologies. The treatment of contaminants in the vadose zone is further accelerated using CO2 SWI in tandem with the MicroBlower™.
About SRNL: SRNL is DOE’s applied research and development laboratory at the Savannah River Site (SRS). SRNL puts science to work to support DOE and the nation in the areas of national and homeland security, energy security and environmental management. The management and operating contractor for SRS and SRNL is Savannah River Nuclear Solutions, LLC.
About Tersus Environmental: Tersus Environmental develops and markets advanced innovative technologies for the remediation of soil and groundwater. They offer engineered sustainable solutions to help their clients reduce uncertainty, minimize risks, and achieve cost-effective results.
Tersus Environmental’s marketing efforts include providing technical support, training, and business development for technology leaders in the field of in situ soil and groundwater remediation. Tersus Environmental also provides global sales management and marketing services for inVentures Technologies’ complete family of groundwater remediation products based on the worldwide-patented Gas inFusion technology, which allows for supersaturated levels of dissolved gas into liquids.
Tersus Environmental can be a valuable partner to consultants, as they have intimate knowledge of leading edge technologies, their appropriate applicability and their advantages and limitations. Their customers include national and regional consulting firms and federal and state governments.
