EDS-ER™ (Electron Donor Solution – Extended Release)

Released in 2011, EDS-ER™ was the first water-mixable vegetable oil based organic substrate to provide a lasting source of carbon and hydrogen for enhanced reductive dechlorination and other bioremediation processes. EDS-ER™ is shipped as a 100% fermentable substrate concentrate to create the right aquifer conditions for anaerobic remediation. EDS-ER™ contains refined, bleached, and deodorized soybean oil and surfactants. The main role of the surfactant is to sufficiently reduce the energy (γo/w) required to increase the surface area so that spontaneous dispersion of oil droplets occurs, and the system is thermodynamically stable. When mixed with water, EDS-ER™ spontaneously becomes an emulsified vegetable oil (EVO).

Advantages:

  • Easily mixes with water, simplifying field operations
  • Spontaneously forms a high-quality, low-droplet size oil-in-water emulsion that easily and uniformly disperses in the aquifer
  • 100% fermentable and contains no water
  • A slowly fermenting product than can provide electrons for up to five years
  • Contains refined, bleached, and deodorized (RBD) food-grade soybean oil
  • Preservative free • Long shelf life
  • Lower transportation costs when compared to other EVO products
  • Up to 50% less packaging material required
  • Lower carbon footprint
  • USDA Certified Biobased Product
  • Can be injected into existing wells or via direct push
  • Decreases number of necessary injection points for low permeability structures
