Tersus TASK - Surfactant-Enhanced Aquifer Remediation (SEAR)
Our anionic surfactant formulations have the unique ability to selectively desorb and liberate sorbed petroleum hydrocarbons from soil and fractured bedrock surfaces allowing for their improved mass recovery and or improved treatment by other remediation techniques. Supported by nearly two decades of research and formulation testing at the University of Oklahoma,
Tersus - Electron Donors
EDS-ER™ (Electron Donor Solution, Extended Release) is a long-lasting source of carbon and hydrogen required for enhanced reductive dichlorination and other bioremediation processes. 100% of the EDS‑ER™ you buy will serve as a fermentable substrate to create the right aquifer conditions for anaerobic remediation. When mixed with water, EDS-ER™ spontaneously becomes an emulsified vegetable oil (EVO). That said, most EVO products in the market are shipped as concentrated emulsions containing water. EDS-ER™ is shipped without water, typically reducing shipping costs by 50%.
Tersus - In Situ Chemical Reduction System
iSCR combines both biological processes and ZVI particle driven abiotic pathways to chemically reduce persistent organic compounds such as chlorinated solvents, pesticides and energetics into harmless end products. ISCR is often used in conjunction with an electron donor substrate like Tersus’ EDS-ER™. The incorporation of ZVI enhances chlorinated contaminant remediation by enabling various chemical reduction pathways and limits the formation of undesirable chlorinated contaminant breakdown products such as Cis-DCE and vinyl chloride.
Tersus - Simple Versatile System
The Waterloo Emitter™ is a simple, low cost device designed for the controlled and uniform release of oxygen, or other bio-enhancing amendments, to encourage and sustain the growth of microorganisms required for in situ bioremediation of contaminated groundwater. The patented technology (U.S. Patent # 5,605,634) enables steady, direct diffusion of oxygen into an aquifer through pressurized silicone or LDPE tubing. Continuous, consistent release of oxygen into the tubing creates the ideal concentration gradient driving this passive system, without ‘bubbling off’ excess oxygen. Emitters are ideal for the bioremediation of BTEX and MTBE using oxygen. The diffusive process provides immediate bioavailability of molecular oxygen for aerobic biodegradation enhancement; therefore, no loss of the amendment gas occurs. The Waterloo Emitter can also encourage desirable abiotic reactions (pH adjustment, hydrolysis, etc.).
Nutrisulfate - Sulfate Enhanced Bioremediation
Enhanced aerobic bioremediation technologies such as the iSOC gas inFusion technology or the use of oxygen releasing compounds such as TersOx are commonly used to accelerate naturally occurring in situ bioremediation of petroleum hydrocarbons, and fuel oxygenates such as MTBE and TBA, by indigenous microorganisms in the subsurface. However, these indigenous microorganisms do not function well in the high contaminant concentrations of the source area. Moreover, the oxygen technologies have to overcome the anaerobic conditions of the source area and often the presence of iron.
Dissolved Phase Anaerobic
NanoEVO - Self-Emulsifier
Tersus Environmental has introduced a nanoscale emulsified vegetable oil, called NanoEVO™. Nanoemulsions are defined as emulsions with droplet sizes typically ranging between 50 and 500 nanometers. As reported by the Applied Surfactant Laboratory at the University of Oklahoma, the median droplet size for NanoEVO™ is approximately 50 nanometers (0.05 microns), which is about 20 times smaller than other commercially available products. The small size of the particles in our NanoEVO™ delivery system offer a number of benefits including:
