Tersus Environmental, LLC products
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 - Model EDS-ER - 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 - Model ISCR - 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 - Model Waterloo Emitter - 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.).
