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%.
At room temperature, EDS-ER™ is a liquid material with an appearance, viscosity and freezing point similar to vegetable oil. Unlike common EVO products that freeze at ~0°C and require preservatives, EDS‑ER™ is preservative free and has a shelf life of over two years without spoilage.
