Surbec Environmental (www.surbec.com) and Tersus Environmental (www.tersusenv.com) announced today the signing of a Distribution Agreement between the two firms. Under the terms of the agreement, Tersus Environmental will market, promote and serve as the worldwide distributor of Surbec’s leading surfactant technology and related products. The patented anionic surfactant formulations have the unique ability to selectively desorb and liberate sorbed petroleum hydrocarbons from soil and fractured bedrock surfaces.
A key efficacy metric for surfactants is the reduction of the interfacial force, which is the force that keeps the oil trapped within pores. Most nonionic surfactants (conventional surfactants) reduce this trapping force by about an order of magnitude. TASK™ (Tersus Advanced Surface Kinetics) reduces the interfacial force by three to four orders of magnitude allowing improved mass recovery and improved treatment by other remediation techniques.
Tersus’ anionic biodegradable surfactants provide considerable advantages.
- Dramatic reduction in cost
- Minimal surfactant mass – usually 0.5 to 0.9 weight percent
- 1 to 1.4 pore volumes for up to 95% mass removal
- The recovered oil and water gravimetrically separate within 30 minutes, making the waste stream easy to handle
- Low-cost solution – less surfactant, low disposal costs.
Supported by nearly two decades of research and formulation testing at the University of Oklahoma, TASK™ can address a wide range of applications related to hydrocarbon contamination, including:
- In situ soil and groundwater remediation
- Emergency spill clean-up
- Pipeline cleaning and spill clean-up
- Tank cleaning and sludge removal
David Alden, Technical Associate with Tersus was a guest panelist on Biotechnologies at the 2014 NC Federal Advanced Technologies Review (NCFATR) held on June 4/5, 2014 in Raleigh, NC. The Federal Advanced Technologies Review focus was on the future advanced technology needs of the Department of Defense (DoD) and other federal agencies within North Carolina. United States Senator Richard Burr, the North Carolina Military Business Center (NCMBC), North Carolina Military Foundation, University of North Carolina and the Institute for Defense and Business hosted the event.
