TersOx™ - Inorganic Peroxygen for Enhanced Aerobic Bioremediation
RemBind designed to treat TPH, PAH, PFOS, PCBs, PCPs, and various pesticides
Sulfate Enhanced Bioremediation
As delivered, the physical state of EDS-ER™ (electron donor solution – extended release) by Tersus Environmental is significantly different than standard emulsified vegetable oil (EVO) products. Whereas other EVO products are concentrated emulsions containing water, EDS-ER™ is a water-mixable oil; it contains no water. Thus, the costs for shipping EDS-ER™ are about 50% less than conventional products.
At room temperature, EDS-ER™ is a liquid material with an appearance and viscosity roughly equivalent to vegetable oil. Unlike common EVO products, EDS-ER™ will not separate, will not freeze, and has a shelf life of 2 years without spoilage.
Tersus Environmental is proud to announce that EDS-ER™ does NOT contain ethoxylated polysorbate surfactants. As you may know, many environmental remediation injectates, such as emulsified vegetable oils use biodegradable non-ionic surfactants. Unfortunately, ethoxylation, the manufacturing process that creates these surfactants (e.g., polysorbates) often results in these products containing 1,4-dioxane.
EDS-ER™ is a simple, safe, low-cost solution for the bioremediation of halogenated compounds (e.g., PCE, TCE, DCE, VC, TCA, CT, etc.), nitrates, perchlorate, energetics, and select immobilization of oxidized heavy metals.
Field Application Design
EDS-ER™ applications are easily tailored to meet site-specific conditions. Typical configurations consist of grid and barrier patterns and application in excavations or trenches. The product’s low viscosity allows subsurface distribution through direct-push injection points, hollow-stem augers or pumped through existing wells.
